Bhendi crop is grown throughout the year. Various types of pests infest this crop. Jassids infestation is mainly observed during the cropping period. Let's know about this insect. • This insect is green in colour. • Apart from bhendi crop, this pest also damages crops like cotton, potato, brinjal, tomato etc. In some crops, it acts as a vector for viral diseases. • Both nymphs and adults are green in colour and triangular in shape. • These insects mostly live on the lower surface of the leaves. • The nymph does not have wings and cannot fly, Adult insects move from one leaf to another or from one plant to another. • Adults and nymphs suck the cell sap from leaves. As a result, the edges of the leaves turn yellow and turn upward, leaves become cup-shaped. • Due to the presence of a toxic element in its saliva, leaves begin to dry and become brittle. • To monitor this pest, install yellow sticky traps in the field. • At initial stages of pest infestation, neem oil @ 50 ml or garlic extract @ 500 g or neem extract @ 20 ml (1% EC) to 40 ml (0.15% EC) or Verticillium lecanii, a fungal base powder 40 gm should be sprayed by dissolving in 10 liters of water. • To control this, spray Buprofenzin 70 DF @ 5 ml or deltamethrin 2.8 EC @ 5 ml or thiamethoxam 25 WG @ 4 gm or imidacloprid 17.8 SL @ 4 ml or acetamiprid 20 SP @ 4 gm by dissolving in 10 liters of water.
