在无气温逆增条件下,使用不同浓度、不同用量的溴氰菊酯油烟剂防治褐边绿刺蛾、马尾松毛虫、竹螟和竹蝗的试验,证实油烟剂可以在无气温逆增条件下使用。防治褐边绿刺蛾、3龄以下马尾松毛虫,25%溴氰菊酯用量需8mL667m2;防治5、6龄松毛虫需25%溴氰菊酯16mL667m2,两者油烟剂用量都为400mL667m2,效果良好;防治竹螟、竹蝗需用25%溴氰菊脂25mL667m2以上,油烟剂500mL667m2以上,才能取得较好的防治效果。非气温逆增条件下使用油烟剂,用户更方便,可进一步推广。
In the condition of no temperature increase and reverse addition, the experiments of using different concentration and dosage of deltamethrin fume-controlling agent to prevent and cure Brown moth, Dendrolimus punctatus, Chilo suppressalis and Locust locust showed that the fume-releasing agent can be used under the condition of no temperature increase Under use. The control of brown moths, 3-day-old Dendrolimus punctatus, 25% deltamethrin dosage required 8mL667m2; prevention and control of 5,6-year-old pine caterpillar 25% deltamethrin 16mL667m2, both the amount of soot are 400mL667m2, the effect Good; prevention and treatment of bamboo borer, bamboo locust 25% 667m2 with 25% deltamethrin above, soot 500mL667m2 more in order to achieve better control effect. Non-temperature inverse increase in the use of soot under the conditions, users more convenient and can be further promoted.
