Paddy Pests and Disease Management-Plant Hoppers-BASF

For management of Plant Hoppers:
• These hoppers include, white backed plant hopper and brown plant hopper.
• Both nymphs and adults of these pests suck the cell sap particularly from the leaf-sheath from July to October. The crop dries up in patches.
• As the plants dry up, the hoppers migrate to the adjoining plants and kill them. In a few days, the area of the dry patches enlarges.

For management,
• Foliar spray of Fenmezodiatiaz 200 g/l SC @ 60 ml per acre at 45-50 days after transplanting followed by Pymetrozine 50% WG @ 120 gms per acre at 70 Days after transplanting.
• Repeat the spray if necessary. For better effectiveness, use knapsack sprayer while directing its spray towards the base of the plants.
• If the damage is noticed at hopper burn stage, treat the affected spots along with their 3-4 m periphery immediately as these spots harbour high population of the insect.
• About one month after transplanting, a few plants in the field should be slightly tilted and tapped 2 or 3 times at the base at weekly interval. When minimum 5 planthoppers per hill (ETL) are seen floating in the water.
