Increase in Rice plant hopper Population (ਰਾਤੋ ਰਾਤ ਝੋਨੇ ਦਾ ਤੇਲਾ ਕਿਉ ਵੱਧ ਜਾਂਦਾ ਹੈ)

A few reasons and role of synthetic parathyroid in multiplication of Rice plant hopper discussed in the video. Plant hoppers: These hoppers include, white backed planthopper and brown planthopper. 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 enlarge. 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, spray 94 ml Pexalon 10 SC (triflumezopyrim) or 80 g Osheen/Token 20 SG (dinotefuran) or 120 g Chess 50 WG (pymetrozine) or 800 ml Ekalux/Quinguard/Quinalmass 25 EC (quinalphos) or 80 ml neem based bio-pesticide, Ecotin (azadirachtin 5%) or 4 litres PAU Homemade Neem Extract in 100 litres of water per acre. Repeat the spray if necessary. Prefer Ecotin or PAU Homemade Neem Extract at pest initiation stage. 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 alongwith their 3-4 metre periphery immediately as these spots harbour high population of the insect.
