Fruit rot extends to the seedcavity making it internally seed borne pathogen.Die back in chilliChoanephora on stem & leaf rotPhytoplasmal leaf deformationManagementPeriodical spray of systemic insecticides isnecessary to control vector.Uproot the severely infected plants and burn justbefore starting of spray schedule.Avoid early transplanting before third week ofAugust to escape leafhopper population.During first sign of initial infection, sprayTetracycline @ 100 ppm twice at 10-12 days intervalto check the multiplication of phytoplasma in thehost tissue.CHILLI/CAPSICUMDieback and Anthracnose (Choanephoracapsici, Colletotrichum capsici)SymptomsDisease initiate on tender twigs from the apical top ofthe plant as necrosis and withering. It progresses fromtip to downward. Choanephora capsici rotted leavesand twigs clearly show black sporangial structure overit. The twigs are water soaked, brown and dieback asthe infection spreads downward. Later on infectedtwigs developed several minute acervuli. Symptomson red fruits are more commonly observed than greenfruits. Small, irregular, sunken, light brown lesions wereobserved on mature fruit. Most often they are coalescedand become papery on green fruits. Apparently fruitslooking healthy during harvest may show the symptomsof diseases during drying.
