PEST / BACTERIAL / FUNGAL IDENTIFICATION IN CROP SYMPTOMS SUGGESTED PRODUCT American Bollworm Larva feed on the leaves initially and later bore onto the square/boll by thrusting their head alone inside, leaving the rest of their body outside. Meta + BT Pink Bollworm Larvae feed on flower buds, and flowers and bore into cotton bolls. Meta + BT Tobacco Caterpillar Larva feeds gregariously on the leaves and skeletonizes them leaving only the veins and midrib. Traps + BT + Meta Aphids Tender shoots and undersurface of the leaves are mostly infested. Lifeline + Traps + BT Jassid Nymphs and adults suck the sap from the undersurface of the leaves causing the yellowing of leaves. Lifeline + Traps + BT Thrips Nymphs and adults scrap the tissue and suck the sap from the epidermis of the leaves. Lifeline + Traps + BT Whitefly Irregular yellowing (Chlorotic spots) of leaf tissue. Lifeline + Traps + BT Mealybug White fluffy mass of mealybugs can be seen on the underside of the leaves, near growing tips and stems with waxy secretions. Lifeline + Traps + BT Mites Fine webbings can be seen on the undersurface of the leaves. Acarida + Traps + BT Fusarium Wilt The earliest symptoms appear on the seedlings in the cotyledons which turn yellow and then brown. The base of the petiole shows a brown ring, followed by wilting and drying of the seedlings. Indofa + Bacillus Anthracnose The fungus infects the seedlings and produces small reddish circular spots on the cotyledons and primary leaves. Indofa + Bacillus Seedling Blight Small, water-soaked, circular, or irregular lesions develop on the cotyledons. Later, the infection spreads to the stem through the petiole and causes withering and death of seedlings. Indofa + Bacillus Angular Leaf Spot Small, dark green, water-soaked areas develop on the lower surface of leaves, enlarge gradually and become angular when restricted by veins and veinlets and spots are visible on both the surface of leaves. Indofa + Bacillus Vein Blight/ Vein Necrosis/ Black Vein The infection of veins causes blackening of the veins and veinlets, giving a typical “blighting” appearance. On the lower surface of the leaf, bacterial oozes are formed as crusts or scales. Indofa + Bacillus Black Arm On the stem and fruiting branches, dark brown to black lesions are formed, which may girdle the stem and branches to cause premature drooping off of the leaves, cracking of the stem, and gummosis, resulting in the breaking of the stem. Indofa + Bacillus Square Rot/ Boll Rot On the bolls, water-soaked lesions appear and turn into dark black and sunken irregular spots. The infection slowly spreads to the entire boll and shedding occurs. Indofa + Bacillus
