(3) Trichogramma bee packs were also effective at the peak of spawning. (4) When necessary, spray 2.5% trichlorfon powder, 1.5-2.5kg per 667m2, or spray 90% crystal trichlorfon 1000 times or 50% icacas EC 1 000 before 3rd instar. Double fluid. (5) Using poison sticks to kill every 667m2, use 80% of dichlorvos emulsifiable concentrate 10og, 0.75L of water, and then use 0.33m large branches, one end bundled with waste cotton dip liquid 14ml, and then each 3.33.3m2 spacing Insert one, 60 plugs per 667m2, smoke treatment effect is good. (6) Use 90% trichlorfon emulsifiable concentrate 100ml, add ammonium sulfate 150g and dry sand 75g, add 2 parts of ammonium nitrate and 1 part of grasshopper make 200g of combustion agent, and then put the resulting aerosol into a diameter of 15cm , 24cm high iron drums or bamboo drums, in the windless morning or dusk in the fire in the Maeda, as long as the smoke continued in the field for 20 to 30 minutes, the small bridges can be dead to death, can treat the stem corn 螟.
