用炉渣作载体制成的1605颗粒剂,防治玉米螟效果虽好,但很多地方炉渣来源困难,筛制较费工。去年,我区应用细砂代替炉渣作载体,加粘着剂后再拌乙基1605制成颗粒剂,防治玉米螟面积13.18万亩,防治效果达77.8％。细砂的来源较广,成本低廉,筛制容易,投入玉米心叶内滚动性 Slag as a carrier made of 1605 granules, prevention and control of corn borer effect is good, but many local sources of slag is difficult, screening more costly. Last year, my area of ​​fine sand instead of slag as a carrier, add adhesive and then mixed with ethyl 1605 granules, prevention and control corn borer area of ​​131,800 mu, prevention and control of up to 77.8%.
