苏云金杆菌(Bailus thuringiensis)140或018工业菌剂每亩用200～255克,加杀灭菊酯20%乳剂每亩8毫升混用防治第二、三代红铃虫,虫口减退率和铃害下降率分别为80.5～93.4%和68.8～84.6%;杀灭菊酯每亩40毫升单用效果分别为96～97.2%和84.6～95.8%,都能有效控制红铃虫的危害。棉花产量测定表明,菌剂加菊酯混用使皮棉增加21.3～30.9%,菊酯单用增加11.4%。
Bacillus thuringiensis (Bailus thuringiensis) 140 or 018 industrial acreage with 200 ~ 255 grams per mu, add fenvalerate 20% Emulsion 8 ml per mu mixed with the second and third generation of pink bollworm, population decline and boll decline rate Respectively 80.5-93.4% and 68.8-84.6%. The single effect of fenvalerate at 40ml per acre was 96-97.2% and 84.6-95.8%, respectively, which could effectively control the harm of Helicoverpa armigera. The cotton yield test showed that inoculation with inoculant increased the lint by 21.3-30.9% and that by pyrethroid increased by 11.4%.
