Seed treatment with Trichoderma @ 0.6 to 1%depending upon soil and pathogen status.Remove all weeds from field.DrenchTrichoderma @ 1% suspension after20 days of sowing to reduce early infection inbeans.Drench Copper Oxychloride @ 0.3% near the collarregion in evening for immediate disease control inbeans only.Powdery Mildew (Erysiphe pisi)SymptomsDiesease appears as white to light gray, powderyfungal spores on leaves, twigs, tendrils and pods aspustules. Soon these pustules coalesce and cover allfoliar part of pea. Infection of pods leads to partialfilling of the grain and pod remain smaller in size.Outer skin of infected pods becomes gray in colourand rough.Rust (Uromyces fabae, Uromyces pisi andU. phaseoli)SymptomsCharacteristic symptoms observed as minute, slightlyraised pustules on all above ground plant parts.Generally elongated pustules are seen on stem. Rustpustules are never observed on pods of pea. Thesepustules on pea are distinct, faint yellow, circularconsisting of numerous uredospores. Later on darkred coloured teleutospores are formed on the leavesand tendrils. Early bloom stage of crop to four weeksbefore harvest is most critical period for rust andmust be protected from the infection.Uredo pustules on pea stemPowdery mildew on foliageManagementAvoid delay in sowing and complete up to firstfortnight of October.Always use tolerant varieties.Foliar spray of Penconazole @ 0.025% or Tridemorph@ 0.1% or Dinocap @ 0.1% at 5-7 days interval.Infected crop debris must be burnt after harvestingof pods.Rust pustules on cowpeaDISEASE MANAGEMENT/LEGUMINOUS & VEGETABLES (PEA AND BEANS)37
