ManagementBurning of infected crop debris is very effective forreduction of inoculum.Use rust tolerant variety of pea.Avoid delay in sowing of pea and complete up tofirst fortnight of October.Fungicidal sprays should be done in critical periodif an average of two pustules per leaf is observedin the field.Use Flusilazole or Hexaconazole @ 0.025 % orBitertanol @ 0.05% or Triadimephon @ 0.05% atinterval of 5-7 days for effective control.Leaf Blight (Pseudocercospora cruentaand Cercospora cruenta)SymptomsDisease appears as black, sooty and moldy growth offungus on all foliar part. Initially the spore mass areolivaceous dark brown and spread very fast in thefield. Quick defoliation is characteristic feature of thedisease, which leads to naked stem and twigs on theplant. Symptoms of Cercospora are observed as smallcircular brown spots with reddish margin. Aschochytablight is a severe disease of cowpea, French bean andpea. Aschochyta paseolorum infects cowpea producinglarge, circular to irregular brown spots with reddishmargin on leaves and all other plant parts.Spray should be started immediately after diseaseinitiation. Delay in spray schedule may not giveproper control due to very fast secondary infectionrate.Avoid delay in sowing of kharif cowpea and it mustbe completed latest by last week of June.Collect the defoliated leaves and burn in field itselfto reduce the inoculum at source.Sclerotinia Blight (Sclerotinia sclerotiorum)SymptomsDisease is observed as wet, soft and white rotting ofthe tissues. Very soon white fungus growth is observedon the rotted portion. Later on embedded sclerotia inwhite mycelium is formed on the infected portion aswell as inner portion of pith and fruits. Primary infectionon pea and cow pea always starts from floral infectionfollowed by pods. Seeds converted into sclerotiabecome concomitant mixture during threshing.Sclerotina rot in French beanPseudocercospora black leaf blightManagementTwo to three foliar sprays of Hexaconazole @0.025% or Biteranol @ 0.05% or Difenconazole @0.025% at 6 days interval.ManagementAll infected part must be carefully collected andburnt before drying of the plants.Seed cleaning is essential to remove the sclerotialmixture during threshing and processing.Deep ploughing, low land paddy with continuousstagnation of water reduces the sclerotialpopulation.Close planting and dense canopy of plant shouldbe avoided.Remove all weeds particularly from the field.38 Integrated Pest Management Schedule for Vegetables
Fungicidal spray must be started at early bloomstage of flowering stage.Alternate spray of Cabendazim @ 0.1% andMancozeb @ 0.25% at 7-10 days interval isessential.Bacterial Blight (Xanthomonas campestrispv. phaseoli (common blight); X. phaseolivar. fuscans (Fuscous blight), Pseudomonassyringae pv. phaseolicola (Halo blight),P. syringae pv. syringae (Brown spot blight).SymptomsDisease is first seen as small translucent, water soakedspots on leaves. Symptoms of common blight, fuscousblight and brown blight are difficult to differentiateon the basis of symptoms except, isolation of casualorganism. However, the infected tissue may turnyellow and die to form lesions of various sizes andshapes. Bigger blotch symptoms appear on the leavesin severe cases of common blight particularly in rainyseason. Small spots appear on pods of different ages.Vascular discoloration is evident in severe incidence.Halo blight has most of the symptoms of commonblight along with a chlorotic halo.Field sanitation by burning of all the infectedleaves and crop debris.Use of clean, disease-free seed and tolerantvarieties.Seed soaking in Streptocycline solution @ 100ppm for 30 minutes.Proper drainage should be maintained in the fieldto avoid water stagnation.Sowing time should be adjusted in such a way thatfruiting stage should not coincide with heavy rainperiod.Cow pea Golden Mosaic (Viral disease)SymptomsThis is an aphid borne viral disease caused by potyvirus while white fly transmitted mosaic is geminivirus. Symptoms appear as yellow and green mosaicpatches on the apical leaves. Lateron most of theleaves become complete yellow. Infected pods turn toyellow from normal green colour. Fruit setting is alsoreduced in infected plants.Yellow mosaic of cowpeaBacterial blight in cowpeaManagementCrop rotation of about 2-3 years is sufficient todispose off over wintering bacteria.ManagementSoil application of Carbofuran @ 1.5 kg ai/ha duringseed sowing.Use resistant lines like Arka Garima, Cowpea-263and KS-10.Rouging of infected plants at initial stage.Foliar sprays of Abamectin @ 0.05% at 10 daysinterval up to flowering stage.DISEASE MANAGEMENT/LEGUMINOUS & VEGETABLES (PEA AND BEANS)39
