Alhoewel hierdie middel omvattend onder ‘n groot verskeidenheid toestande getoets
is, waarborg die registrasiehouer nie dat dit onder alle toestande doeltreffend sal wees
nie aangesien die werking en effek daarvan beïnvloed kan word deur faktore soos
abnormale klimaats- en bergingstoestande, kwaliteit van verdunningswater,
verenigbaarheid met ander stowwe wat nie op die etiket aangedui is nie en die
voorkoms van weerstand van die siekte teen die betrokke middel sowel as die metode,
tyd en akkuraatheid van toediening. Verder aanvaar die registasiehouer nie

verantwoordelikheid vir skade aan gewasse, plantegroei, die omgewing of vir nadelige
effek op mens of dier of vir ‘n gebrek aan prestasie van die betrokke middel as gevolg
van die versuim van die gebruiker om etiketaanwysings na te kom of as gevolg van die
ontstaan van toestande wat nie kragtens die registrasie voorsien kon word nie.
Raadpleeg die verskaffer in die geval van enige onsekerheid.
VOORSORGMAATREËLS
Vermy kontak met oë, vel en klere.
Moet nie eet, drink of rook terwyl gemeng of gespuit word nie.
Moet nie spuitnewel inasem nie.
Dra ‘n beskermende oorpak en ‘n geskikte masker vir die beskerming teen plaagdoders.
Dra rubberhandskoene en gesigmasker wanneer gemeng en gelaai word.
Gedurende toediening - dra ‘n oorpak en rubberhandskoene.
Was met seep en water na hantering.
Trek skoon klere aan en was dan hande en gesig.
Was besoedelde klere daagliks.
Moet nie fonteine, damme, riviere, eetgerei, voedsel of voer besoedel nie.
Vermy die oorwaai van spuitnewel na ander gewasse, weiding, riviere, damme en areas wat
nie behandel word nie.
Keer die leë houer om oor die spuittenk of mengbak en dreineer vir minstens 30 sekondes
nadat die vloei tot ‘n gedrup verminder het. Spoel die houer daarna drie keer uit met ‘n
volume water gelykstaande aan ‘n minimum van 10% van die houer. Gooi die spoelwater by
die inhoud van die spuittenk voordat die houer op die voorgeskrewe wyse vernietig word.
Vernietig leë houer deur vol gate te kap en raak ontslae by wyse van verbranding of deur dit
in ‘n gronvulling te begrawe. Moet nooit houer vir enige ander doeleindes hergebruik nie.
Maak spuittoerusting deeglik skoon na gebruik. Doen weg met die waswater op ‘n veilige
plek.
SIMPTOME VAN MENSLIKE VERGIFTIGING:
Moontlike tekens of simptome van menslike vergiftiging sal aanvanklik vergroting van die
pupille, vertraagde asemhaling en tekens van verdowing wees. Ernstige vergiftiging mag
lomerigheid, bewing van spiere en rukkings veroorsaak.
NOODHULPBEHANDELING:
Kry mediese hulp in alle gevalle. Verwyder persoon van die oorsaak van vergiftiging en stel
hom gerus en hou hom stil.
Inaseming: Neem pasiënt na vars lug, weg van die vergiftigingsbron. Dien kunsmatige
asemhaling toe of geslote hartmassering indien nodig. Hou die lugweë oop.
Inname: Kry mediese hulp onmiddelik. Moet nooit iets per mond aan ‘n bewustelose persoon
toedien nie, insluitende mond-tot-mond asemhaling. Neem pasient onmiddelik na die naaste
geneesheer.
Vel: Verwyder besoedelde klere en was besmette liggamsdele deeglik met baie seep en
water. Moet nie vel hard vryf nie.
Oë: Spoel oë vir minstens 15 minute moet oorvloedige hoeveelhede water uit.
NOTA AAN GENEESHEER:
Daar is geen bekende spesifieke teenmiddel vir akute abamektien-vergiftiging nie. In die
geval van simptomatiese simptome moet ondesteunde behandeling, wat van die
simptomatologie sal afhang, voorsien word teen einde lewensfunksies te onderhou.
INSEK WEERSTANDSBEHEER:
Mecti is ‘n groep 6A Insekdoder. Enige insek populasie sal enkele individue bevat wat
weerstand het teen Mecti en ander Groep 6A Insekdoders. Die weerstandbiedende individue
domineer die insekpopulasie wanneer hierdie insekdoder herhaaldelik gebruik word. Die
weerstandbiedende insekte mag dalk nie deur Mecti of ander Groep 6A Insekdoders beheer
word nie. Ervare konsultante moet gekontak word oor plaaslike weerstandsbeheer
strategieë.. Die volgende klassifikasies is gebasseer op die manier van werking, hierdie
klassifikasies bewys dat insek en myt weerstand teen insekdoders en mytdoders ontstaan as
gevolg van verhoogde metabolisme, verlaagde penetrasie of gedrags veranderinge. Hierdie
verandering is nie gekoppel aan enige “site of action” klassifikasie nie, maar is spesifiek vir

individuele chemikalieë of chemiese groepe. Nieteenstaande, bly die afwisseling van
mengsels met verskillende chemiese klasse steeds ‘n lewensvatbare bestuurstegniek.
Die vertraging van insekmiddel weerstandbiedendheid kan verky word deur:
• Vermy eksklusiewe, herhaaldelike gebruik van insekdoders van dieselfde
chemiese supgroep.
• Integreer veskeie beheer maatreëls (chemies, kultuur, biologies) in insekbeheer
programme.
Vir verdere inligting kontak u naaste verspreider.
Weerstandsbiedensheids strategie
Weens die inherente risiko van weerstoestandbiedenheid wat teen enige produk kan
ontwikkel, word dit streng aanbeveel dat Mecti in ‘n goeie weerstand biedenheidsbestuursprogram
gebruik word. Dit sluit in die gebruik van produkte met verskillende modes
van werking en toedienings moet aangewend word wanneer nodig volgens goeie
geïntegreerde plaagebeheer programme.
Moet nie meer as:
3 bespuitings van Mecti per seisoen op katoen, of
2 bespuitings per seisoen op sitrus, of
4 bespuitings teen die laagste aanbevole dosis per seisoen op appels en pere, of
4 bespuitings per groeiseisoen op aarbeie, of
5 bespuitings per seisoen op tamaties toedien nie.
Mecti moet met geskikte spuittoerusting, wat in goeie werkende toestand en korrek
gekalibreer is, toegedien word. Deeglike en egalige bedekking van die gewas is ‘n vereiste.
Mecti word vinnig deur die plant geabsorbeer en onder normale toestande weerstaan dit
afwas, mits die spuitmengsel voldoende tyd gegun word om heeltemal droog te word.
Oorbespuiting mag minder doeltreffende beheer teweeg bring weens die afloop van Mecti
vanaf die blaaroppervlak.
Mecti kan vir voorkomende en korrektiewe behandelings van spinmyte gebruik word op
katoen en tamaties. Spuitneerlae van Mecti het ‘n minimale uitwerking op voordelige
natuurlike vyande, insluitende roofmyte, wat die residuele mytbeheer kan verleng. Op appels
en pere is Mecti mees geskik vir gebruik in die GPB-program (Geïntergreerde Plaagbeheer).
Teen die aanbevole dosis sal sommige spinmyte oorleef, wat sal dien as ‘n voedselbron om
die opbou van roofmyte te bevorder.
Mecti het getoon dat dit nie die veselgehalte van katoen nadelig beïnvloed nie.
GEBRUIKSAANWYSINGS:
Gebruik slegs soos aangedui.
Mecti is doeltreffend vir die beheer van volwasse en onvolwasse stadia van myte,
sitrusblaaspootjie en larwe stadia van Amerikaanse blaarmyner.
Mecti het, algemeen gesproke, ‘n redelike stadige aksie. Alhoewel die spinmyte en
blaarmyner kort na blootstelling verlam word, sal tussen 3 en 5 dae nodig wees, afhangende
van omgewingstemperature, om maksimum mortaliteit te verkry. Gedurende hierdie periode
is voeding deur die plae baie beperk en plantbeskadiging minimaal.
LUGTOEDINGING:
Lugtoediening van hierdie produk mag slegs deur ‘n geregistreerde toediener toegedien word,
wat ‘n korrek gekalibreerde, geregistreerde vliegtuig het volgens die instruksies van SABS
Kode 0118 (Lugtoediening van Landboumiddels). Dit is belingrik dat die spuitstof egalig oor
die teikengebied versprei word end ie verlies aan spuitmiddel tydens toediening tot ‘n
minimum beperk word. Ten einde hieraan te voldoen, moet die volgende vereistes nagekom
word.
a.) Toediening parameters:
- Volume: ‘n Minimum spuitvolume van 30ℓ / ha word aanbeveel. Omdat hierdie
produk nie teen ‘n verlaagde dosis ge-evalueer was nie, kan die registrasie houer
nie effektiwiteit waarborg, of verantwoordelik gehou word vir enige ongustige
toestande indien hierdie produk teen ‘n laer dosis, as aanbeveel hierbo, per lug
toegedien word.

- Druppelverspreiding: ‘n Druppelverspreiding van 30-40 druppels / cm 2 moet op
die teikengebied herwin word.
- Druppelgrootte: ‘n Druppelspektrum met ‘n VMD van 250-280 mikron word
aanbeveel. Verseker dat die produksie van fyn druppels (minder as 150 mikron –
hoë dryf en verdamping potensiaal) tot ‘n minimum beperk word.
- Vlieghoogte: Die hoogte van die spuitstukke moet teen ‘n hoogte van 3 – 4
meters bo die teiken area gehandhaaf word. Moenie spuit wanneer die vliegtuig
besig is om te klim, tydens toppunt, gedurende ‘n duik of tydens landing.
b) Toerusting:
Gebruik geskikte atomiseer toerusting (hidroliese spuitneuse of rotasie
atomiseerders) wat geskikte druppel grootte en bedekking sal produseer en
terselfdetyd die minimum verlies van die spuitmiddel deur of “endodrift” (binne teiken
gebied) of “exodrift” (buite teiken gebied) sal waarborg. Die spuitoperateur moet
toerusting gebruik wat ‘n druppelspektrum met die laagste moontlike relatatiewe span
sal produseer.
Alle spuitneuse / atomiseerders moet binne die binne 60 – 75 % van die vliegtuig se
vlerkspan geplaas wees sodat druppels nie in die maalstroom van die vlerkpunt
beland nie.
c) Weerkundige toestande:
Die verskil tussen die nat-en droëbollesing, soos met ‘n swaaihigrometer bepaal,
moet nie 8°C oorskry nie. Die byvoeging van ‘n gesk ikte anti-verdampingsmiddel
word aanbeveel indien die VMD van die druppelspektrum minder as 200 – 250
mikron is.
Staak toediening as die windsnelheid meer meer as 15km / h is.
Lugtoediening van hierdie produk moet nie tydens onstuimige, onstabiele toestande
gedurende die hitte van die dag wanneer stygende temperature en valstome voorkom
toegedien word nie. Neem kennis dat lugtoediening van hierdie produk onder
temperatuur inversie toestande (bespuiting tydens of bo die inversie laag) aanleiding
kan gee tot die volgende:
- Verlaagde effektiwiteit as gevolg van die suspensie en verdamping van klein
druppels in die lug (onvoldoende bedecking).
- Skade aan ander sensitiewe gewasse en / of nie teiken gebiede deur die
beweging van die suspensie spuitdampe weg vanaf die teikengebied.
VERENIGBAARHEID:
Mecti is nog nie in alle tenkmengsels of volgordes van plaagdoderbespuitings getoets nie.
Mecti mag met molasse vir lugtoediening op katoen gemeng word. Mecti moet saam met ‘n
goedgekeurde ligte minerale spuitolie gemeng word vir toediening op appels en pere. Sien
appels en pere onder algemene aanwysings.
As tenkmengsel met sintetiese piretroïede op katoen aangewend word, gebruik altyd laagste
aanbevole piretroïed dosis vir weeklikse beskerming.
Dit is nie nodig om benattings/kleefmiddels by die Mecti mengsel te voeg nie. Raadpleeg
Plaaskem of hul verspreider vir die jongste inligting. Mecti plus olie is op ‘n wye
verskeidenheid appels en pere vir veiligheid getoets. Alhoewel nie alle kombinasies en
volgordes van spuitmengsels volledig geëvalueer is nie, word dit nie aanbeveel om Mecti in
tenkmengsels toe te dien nie. Kontak die naaste verspreider vir die nuuste inligting
aangaande die mengsel.

ALGEMENE AANWYSINGS:
KATOEN:
GRONDTOEDIENING: Wend aan in tot soveel as 200 ℓ water/ha afhangende van die
plantgrootte en die spuittoerusting wat gebruik word.
“TREMLYN”-TOEDIENING: Dien 50 – 100 ℓ van die spuitmengsel/ha net op droëland katoen
wat in “termlyne” geplant is, afhangend van die plantgrootte toe. Plaas ten minste 5 hol-kegel
spuitkoppe van gepaste grootte oor die “tremlyne”. Een spuitkop moet direk oor die top van
elke ry spuit. Een spuitkop moet tussen die twee rye spuit en twee spuitkoppe moet so
geplaas word dat hulle 45 grade opwaarts wys, opgestel op val-arms aan die buitekant van
elk van die twee rye.
TAMATIES:
Gebruik ‘n fyn sproei ten hoë druk en dien slegs toe tot die punt van afloop.
APPELS EN PERE:
Dien toe as ‘n hoë volume, hoë druk dekbespuiting tot die punt van afloop. Voeg 0.25% by
volume van ‘n ligte mineraal spuitolie in die finale (verdunde) spuitmengsel. ‘n Deeglike
bedekking is van uiterste belang. Daar word aanbeveel dat kaptan of swawel spuitstowwe
nie binne 14 dae voor of na ‘n toediening van olie gebruik word, aangesien die olie kolvlekke
op die vrugte en blare mag veroorsaak.
AARBEIE:
Dien toe as ‘n hoë volume, hoë druk dekbespuiting. Deeglike bedekking van beide die bokant
en onderkant van blare is noodsaaklik om spinmyte te beheer
SITRUS:
Aangesien Mecti die mees effektiefste is wanneer dit ingeneem word sal maksimum
effektiwiteit eers waargeneem word twee tot drie dae na toediening. Mecti moet vir die rede
nie gebruik word vir die beheer van groot getalle sitrusblaaspootjie nie (meer as 40%
vrugtebesmetting) waar ‘n uitklop toediening benodig word.
MENGINSTUKSIES:
Maak die spuittenk halvol met skoon water. Meet die benodigde hoeveelheid Mecti af en
meng dit eers in minstens 10 ℓ water (as enige ander produk met Mecti gemeng word, moet
die benodigde volume van daardie produk eers op soortgelyke wyse met water gemeng word
bv. ligte mineraal spuitolie). Roer die water in die spuittenk en voeg die voorafgemengde
produk(te) by. Vul die spuittenk met water terwyl daar geroer word om deeglike vermenging
te verseker.
Roer tydens toediening. Gebruik die voorbereide mengsel dadelik. Moet nie oornag laat
staan nie.
Mecti kan met water gemeng word waarvan die pH-waardes en hardheid wissel wat
normaalweg onder landboutoestande gevind word.

TOEDIENINGSVOORSKRIFTE
Kan as ‘n voorkomende en/of korrektiewe beheermaatreël gebruik word.
Verseker deeglike plantbedekking. Herhaal toediening wanneer nodig
om die mytbevolking onder die ekonomiese drempelwaarde te
handhaaf.
Grondtoediening: Dien in 100-200 ℓ water/ha toe. Moet nie minder as
300 ml Mecti toedien nie.
Termlyn-toediening: Dien 50-100 ℓ/ha van die spuitstofmengsel toe op
droëland katoen, afhangend van die plante grootte. (Moet nie minder as
3ml per 100 m ry gebruik nie).
Lugbespuiting: Dien in 30 ℓ water/ha toe. Moet nie minder as 300 ml
Mecti/ha toedien nie.
Voorkomende Beheermatreël: Dien 300 ml/ha wanneer die spinmytbevolkingsindeks
‘n skielike toename van een week tot die volgende
toon maar voordat die ekonomiese drempelwaarde bereik is. (Sien
“Verkenningstegnieke”).
Korrektiewe Beheermaatreëls: Dien toe teen 600 ml/ha wanneer die
ekonomiese drempelwaarde van spinmytbevolking vir ‘n gegewe
groeistadium van die gewas gebasseer op verkenningsresultate bereik
of oorksry is.
Nood Beheermaatreëls: Gebruik teen 600 ml/ha tydens hewige
mytbesmettings en wanneer klimaatstoestande vinnig vermeerdering
van mytbevolking kan bevorder (baie warm en droë dae).
Nota: Die toediening teen 600 ml/ha kort voor die gewas geoes word
mag die normale ontblaring van die gewas, wat deur die myte
veroorsaak word, vertraag.
Dien toe as ‘n hoë volume, hoë druk volle dekbespuiting toe tot die punt
van afloop. Gebruik tot 2000 ℓ spuitmengsel per ha.
Wanneer jong plante bespuit word, gebruik ‘n minimum van 300 ml
Mecti in nie minder as 500 ℓ spuitmengsel / ha nie en spuit tot die punt
van afloop. Moet nooit 1 200 ml van die konsentraat per ha oorskry nie.
Nota:
1. Vir spinmyte herhaal toediening wanneer nodig.
2. Vir Amerikaanse blaarmyner herhaal toediening elke 7 dae of
wanneer nodig om beheer te handhaaf.
Dien Mecti toe wanneer die rooispinmyt populasie die ekonomiese
drempelwaarde bereik en herhaal wanneer nodig. Dien toe as ‘n hoë
volume (2150-4300 ℓ/ha) hoë druk dekbespuiting tot by alfoop. Indien
minder as 2150 ℓ/ha toegedien word, gebruik ‘n minimum van 750ml
Mecti plus 0,25% spuitolie in genoeg water om deeglike bedekking te
verkry.
Moet nooit meer as 1 500ml/ha per bespuiting toedien nie of meer as
3000 ml Mecti/ha in een groei-seisoen toedien nie.
Appels: Dien toe alleen op boorde waar die GPB program nie
doeltreffende beheer van spinmyte handhaaf nie.
Dien ‘n hoë volume, hoë druk volle dekbespuiting toe wanneer die
eerste tekens van besmetting verskyn. Dien aanvanklik 2 bespuitings
toe met tussenposes van 7-10 dae en herhaal indien nodig.
Gebruik ‘n minimum van 500 ℓ water/ha en deeglike bedekking van alle
plant oppervlakke is noodsaaklik. Moet nooit meer as 4800 ml Mecti per
ha per groei-seisoen toedien nie.
Mecti moet toegedien word sodra blaaspootjie getalle begin toeneem.
Dien toe as ‘n ligte dekkenslaag maar vermy afloop. Herhaal toediening
indien nodig. Moenie meer as twee agtereenvolgende toedienings
aanwend nie met ‘n maksimum van drie toedienings per seisoen.
Mecti behoort afgewissel te word met ander blaaspootjiemiddels om

water weerstand te voorkom. Moet nie toedien as meer as 40% vrugte besmet
is nie. Toedienings sal laeveld en rooimyt onderdruk.

FIRST AID TREATMENT:
Get medical attention in all cases. Remove patient to a well-ventilated area away from source
of poisoning. Keep the patient quiet and reassure him at all times.
Inhalation: Remove patient to a well ventilated area away from source of poisoning. Give
artificial respiration or closed chest cardiac massage if necessary. Maintain open airway
passages.
Ingestion: Obtain medical help immediately. Do not induce vomiting or give anything by
mouth, including direct mouth to mouth resuscitation, to an unconscious person.
Skin: Remove contaminated clothing and wash contaminated body area with plenty of soap
and water. Do not rub skin hard.
Eyes: Flush thoroughly with clean water for at least 15 minutes.
NOTE TO PHYSICIAN:
There is no known specific antidote for Mecti acute toxicity.
In case of symptomatic effects, provide supportive treatment depending on symptomatology
to maintain life functions.
RESISTANCE WARNING:
For resistance management, Mecti is a group 6A insecticide. Any insect population may
contain individuals naturally resistant to Mecti and other group 6A insecticides. The resistant
individuals dominate the insect population if these insecticides are used repeatedly. These
resistant insects may not be controlled by Mecti or other group 6A insecticides, although local
experts should be consulted for local resistance recommendations. The following
classification scheme is based on mode of action. It is recognized that resistance of insects
and mites to insecticides and acaricides can also result from enhanced metabolism, reduced
penetration or behavioral changes that are not linked to any site of action classification but
are specific for individual chemicals or chemical groupings. Despite of this, alternation of
compounds from different chemical classes remains a viable management technique. To
delay insecticide resistance:
*Avoid exclusive repeated use insecticides from the same chemical subgroup.
*Integrate other control methods (chemical, cultural, biological) into insect control programs
For further information contact your local distributor.

Resistance management:
Due to the inherent risk of resistance development to any product, it is strongly recommend
that Mecti be used in a sound resistance management programme that includes the use of
products with different modes of action and applications made, only when necessary, based
on sound integrated pest management programmes.
Do not apply more than:
3 sprays of Mecti per season on cotton, or
2 sprays per season on citrus, or
4 sprays of the lowest rate recommended per season on apples and pears, or
4 sprays per growing season on strawberries, or
5 sprays per season on tomatoes.
Mecti must be applied using suitable spray equipment that is in good working order and
correctly calibrated. Thorough and even coverage of the crop is essential.
Mecti is rapidly absorbed into the plant and under normal conditions resists wash-off provided
the spray mixture has been given adequate time to dry off completely. Over-spraying may
result in less effective control by causing run-off of Mecti from the leaf surface.
Mecti can be used for preventive and corrective treatments for spider mite control on cotton
and tomatoes. Spray residues have a minimum effect on beneficial natural enemies,
including predatory mites, which could extend the residual mite control. On apples and pears
Mecti is most suited for use in the IPM programme. At the recommended dose rate some
spider mites will survive which will serve as a food source to encourage build-up of predatory
mites.
Mecti has been shown not to have a detrimental effect on lint quality.
DIRECTIONS FOR USE:
Use only as directed.
Mecti is effective for the control of adults and immature stages of spider mite, citrus thrips,
and larval stages of American leafminer.
Mecti is, in general, slow-acting and although mites and leafminer become immobilised soon
after exposure, between 3 and 5 days, depending on ambient temperatures, may be required
to achieve maximum mortality. During this period feeding by the pests is very limited and
plant damage is minimal.
AERIAL APPLICATION
Aerial application of this product may only be done by a registered aerial application operator
using a correctly calibrated, registered aircraft according to the instructions of SABS Code
0118 (Aerial Application of Agricultural Remedies). It is important to ensure that the spray
mixture is distributed evenly over the target area and that the loss of spray material during
application is restricted to a minimum. It is therefore essential that the following criteria are
met:
a) Application parameters:
- Volume: A minimum volume of 30 litres per hectare is recommended. As this
product has not been evaluated at a reduced volume rate, the registration holder
cannot guarantee efficacy, or be held responsible for any adverse effects if this
product is applied aerially at a lower volume rate than recommended above.
- Droplet coverage: A droplet coverage of 30-40 droplets per cm² must be
recovered at the target.
- Droplet size: A droplet spectrum with a VMD of 250-280 microns is
recommended. Ensure that the production of fine droplets (less than 150 microns
high drift & evaporation potential) is restricted to a minimum.
- Flying height: The height of the spray boom should be maintained at 3-4 meters
above the target. Do not spray when aircraft is in a climb, at the top or during a
dive, or when banking.

) Equipment:
Use suitable atomising equipment (hydraulic nozzles or rotary atomisers) that will
produce the desired droplet size and coverage, but which will ensure the minimum
loss of product either through endodrift (within target field) or exodrift (outside target
field). The operator must use a setup that will produce a droplet spectrum with the
lowest possible relative span.
All nozzles / atomisers should be positioned within the inner 60% to 75% of the
wingspan to prevent droplets from entering the wingtip vortices.
c) Meteorological conditions:
The difference in temperature between the wet and dry bulb thermometers, of a
whirling hygrometer, should not exceed 8°C. The ad dition of a suitable anti-evporant
is recommended if the VMD of the droplets is less than 200-250 microns.
Stop spraying if the wind speed exceeds 15 km/h.
Aerial application of this product must not be done under turbulent, unstable
conditions during the heat of the day when rising thermals and downdraughts occur.
Also note that the application of this product under temperature inversion conditions
(spraying in or above the inversion layer) may lead to the following:
* Reduced efficacy due to suspension and evaporation of small droplets in the
air (inadequate coverage)
* Damage to other sensitive crops and or non-target areas through the
movement of the suspended spray cloud away from the target field.
COMPATIBILITY:
Mecti has not been tested in all tank mixtures or sequence of pesticide sprays.
Mecti may be mixed with molasses for aerial application on cotton. Mecti must be mixed with
an approved light mineral spray oil on apples and pears. See apples and pears under
general directions.
If tank mixtures with synthetic pyrethroids are applied on cotton, use the lowest recommended
pyrethroid dose for weekly protection.
Mecti does not require the addition of surfactants/aduvants to the spray mixture. Consult
Plaaskem or their distributors for up-to-date information. Mecti plus oil has been tested for
safety on a wide variety of apples and pears. Since all combinations and sequences of
sprays used have not been fully evaluated, it is recommended not to tank mix with Mecti.
Consult your local distributor for the latest information on the different tank mixtures.
GENERAL DIRECTIONS:
COTTON:
GROUND APPLICATION: Apply in up to 200 ℓ water/ha depending on plant size and spray
equipment used.
“TRAMLINE” APPLICATION: Apply only to dryland cotton planted in “tramlines”: using 50 –
100 ℓ of spray mixture/ha depending on plant size. Position at least 5 hollow-cone nozzles of
suitable size over the “tramlines”. One nozzle must spray over the top of each row. One
nuzzle must spray between the two rows and two nozzles should be positioned to point 45
degrees upwards, mounted on drop-arms on the outside of each of the two rows.
TOMATOES:
Use a fine spray at high pressure and only apply to point of incipient run-off.
APPLES AND PEARS:
Apply as a high volume, high pressure cover spray to point of incipient run-off. Add 0.25% by
volume of a light mineral spray oil in the diluted spray mixture. Thorough coverage is
essential. It is recommended not to apply captan or sulphur sprays 14 days prior to or after
an application of oil as the oil may cause spotting on the fruit and leaves.

STRAWBERRIES:
Apply as a high volume, high pressure cover spray. Thorough coverage of both the tops and
underside of leaves is essential to control spider mites.
CITRUS:
As Mecti is most effective when ingested, maximum efficacy may only occur two to three days
after treatment. For this reason, Mecti should not be used for the control of high numbers of
citrus thrips (more than 40 % fruit infestation) where a knock-down treatment is required.
MIXING INSTRUCTIONS:
Half fill spray tank with clean water. Measure out the required quantity of Mecti and premix
this with at least 10 ℓ water. (If any other product e.g. light mineral spray oil is to be mixed
with Mecti, the required volume of that product must be premixed in similar fashion). Agitate
the water in the spray tank and add the premixed product(s) to the tank. Fill spray tank with
water while maintaining agitation to ensure thorough mixing.
Maintain agitation during spraying. Use the prepared mixture immediately. Do not allow to
stand overnight. Mecti can be mixed with waters of different pH values and hardness normally
encountered in agricultural conditions.

Mecti can be used as a preventive or corrective control measure.
Ensure thorough coverage of the plants. Repeat application as
required to maintain the mite population below the economic
threshold level.
Ground application: Apply 100-200 ℓwater/ha. Do not use less
than 300 ml/ha of Mecti.
“Tramline Application: Apply 50-100 ℓ/ha of spray mixture to
dryland cotton, depending on plant size. See General Directions
above. Do not use less than 3ml per 100m row.
Aerial application: Apply in 30ℓ water/ha. Do not apply less than
300 ml Mecti / ha
Preventive Control Measure: Apply Mecti at 300ml/ha when the
spider mite population index shows a sudden increase from one
week to the next, but before the economic threshold level is
reached for a given growth stage of the crop based on weekly
scouting results. See Scouting Techniques and Economic
Threshold Levels below.
Corretive Control Measure: Apply Mecti at 600mℓ/ha when the
economic threshold of the spider mite population has been reached
or exceeded for a given stage of the crops based on weekly
scouting results.
Emergency Control Measure: Apply Mecti at 600ml/ha under
conditions of very severe mite in-festations and when climatic
conditions favour the rapid increase of mite populations (very hot
and dry weather). The application of Mecti at 600ml/ha near
harvest may delay the normal plant defoliation caused by mites
Apply Mecti at first signs of infestations as a high volume, high
pressure, full cover spray to point of run-off using up to 2000 ℓ spray
mixture per hectare. If less than 500 ℓ of spray mixture are applied
(i.e. when spraying young plants) a minimum of 300ml of Mecti per
hectare must be applied in sufficient water to provide a full cover
spray. Never exceed 1200 ml of Mecti per hectare.
Ensure that all foliage surfaces are thoroughly wetted by the spray
to point of run-off.
Spider mites: Repeat application as necessary.
American leafminer: Repeat application after 7 days or as needed
to maintain control.

pressure full cover spray, but avoid run-off. If less than 2 150 ℓ
spray mixture per hectare is applied i.e. low volume, use a minimum
of 750ml Mecti plus 0.25% spray oil per hectare in sufficient water
to obtain thorough coverage. Never exceed 1 500ml Mecti per
hectare per application or 3 000ml Mecti per hectare in one growing
season.
Apples: Apply only to orchards where the IPM programme is not
maintaining effective control of mites.
Apply Mecti as a high volume, high pressure full cover spray at first
signs of infestation. Apply initially 2 sprays 7 – 10 days apart.
Repeat as necessary. Mecti must be applied in a minimum of 500 ℓ
water per hectare to control red spider mite. Thorough coverage of
all plant surfaces is essential. Never exceed 4 800ml Mecti per
hectare per growing season.
Apply Mecti when thrips numbers start to increase. Apply as a film
wet, light cover spray but avoid run-off. Repeat when necessary.
No more than three applications or two consecutive applications
should be applied per season. Mecti should be alternated with
other thrips remedies to retard development of resistance. Do ot
apply if more than 40 % of the fruit is infected. Applications will also
suppress lowveld and redmite.
Note on Red Spider Mite Scouting Techniques for Cotton:
Inspect 48 cotton plants at random in fields up to 15 ha in extent every week from the third
week after germination until first boll split (± week 20). Sample 3 leaves from each plant – 2
leaves from the top and 1 leaf from the middle – and note the total number of adult female
mites present on the sampled leaves. Determine the spider mite population index per plant
as follows:
Total number of female mites/3 leaves/ Spider Mite Population plant
Index
0 0
1 to 10 1
11 to 30 2
30+ 3
Calculate the average index value per field by adding the 48 individual index values and
dividing by 48. Apply Mecti as recommended depending on scouting results for a given
growth stage of the cotton crop. (See Economic Threshold Levels below).
Economic Threshold Levels:
Weeks after Germination 3-10 12 14 16 18 20
Spider Mite Population Index 0.5 0.8 1.1 1.4 1.7 2.0
Economic Threshold Level of Pears and Apples:
Pears: 1 female / leaf throughout the season
Apples: 2 females/leaf up to the end of March and thereafter 1 female/leaf.
