BIOLOGICAL SPECTRUM
PRODUCT INFO
This product is an emulsifiable concentrate insecticide containing 400 g/ltr. of Dimethoate, a wide range insecticide.
Dimethoate is an organic phosphorus ester. It has an enduring systemic action in the control of plant sucking
insects (e.g. aphid, sucking mites) miners and fruit borers. Additionally however, it is remarkably effective as a
contact insecticide against a number of important chewing ectoparasites.
Dimethoate is metabolised in the plant into non-toxic substances. About 3 weeks after treatment no appreciable
residues will be left.
METDHODS OF APPLICATION
This product is to be mixed with water and may be applied with conventional dilute or concentrate ground sprayers.
Add the required dose rate of the product to the half-filled tank and start agitation. Add the remaining water
in the tank and spray the mixture immediately. The spray concentration depends on the type of spray equipment,
the crop, the infestation pressure and the local experience.
Chemical has quick knock-down effect and systemic activity lasts for up to 14 days. The product must be applied
as soon as the first insects appear and repeat 2 - 3 weeks later or as necessary. Timing and number of sprays have
to be decided in function of the level of infestation.
Apply the low rates on small plants, small insects and light infestations of insects. Use intermediate rates on large
insects and heavier infestations. Best results achieved when crop growing vigorously.
Phytotoxicity: Do not use on Chrysanthemum and some other sensitive ornamentals. A preliminary phytotoxicity
trial is recommended on a reduced scale before carrying out the actual treatment on citrus, olive, apricots and
early peach varieties.
Preharvest interval: In general approximately 2 weeks before cropping. Pertinent local statutory regulations
must be complied with! Treated fodder crops must not be grazed or fed to live stock within 7 days after the last
treatment.
To avoid excessive residue at harvest do not exceed the maximum dosage per ha, or the time restriction between
last application and harvest for each group listed in the table hereafter.
IMPORTANT: The product is toxic to bees and should not be applied during the flowering period.

EMERGENCY GUIDELINES
Symptoms of poisoning
Dimethoate is a cholinesterase inhibitor. Signs of overexposure develop after a latent period and may include:
feeling of exhaustion, headache, blurred vision, weakness, confusion, vomiting, abdominal pain, excessive sweating,
salivation, difficulty in breathing, arrhythmia and cardiac failure, unconsciousness and convulsions.
First aid
* I poisoned by skin absorption, remove all contaminated clothing and wash the patient thoroughly with plenty of
water and soap; contaminated clothing should be laundered thoroughly before re-use.
* In case of eye contact, flush eyes with copious amounts of water for at least 15 minutes.
* If product has been swallowed, it should be noted that dimethoate is dissolved in solvents and that inducing
vomiting then involves a risk of aspiration pneumotitis. Induce vomiting by thickling the back of the throat with
a finger. Do not induce vomiting when the patient is unconscious.
* Keep the patient at absolute rest.
Note to physician
If the product swallowed, perform rapid stomach lavage with 5% sodium bicarbonate, taking care to avoid aspiration
into the lungs. Person with manifest peripheral symptoms, should be treated with 2 - 4 mg of atropine sulphate
by intravenous injection. More atropine may be given as needed. In case of respiratory difficulties or convulsions,
should be given atropine and a reactivator immediately. Allow no further exposure to any cholinesterase
activity inhibitor until recovery is assured. Treat symptomatically. Put patient at complete rest in hospital
for at least 72 hours.
Contraindicated: morphine, barbiturates, phenothiazine, tranquillizers and central stimulants of all kinds.
