摘要
为比较多种防治枣瘿蚊药剂在实际生产过程中的效果,选择了3种生物药剂及1种实践常用药剂进行田间试验,结果表明:4种药剂对枣瘿蚊的防治效果均有较长的持效期。30%印楝素乳油具有较好的速效性和持效性,施药第3d,虫口减退率和防效率均达到80%以上,而6000IU/微升苏云金杆菌悬乳剂,0.5%苦参碱水剂,5%高效氯氟氰菊酯防效和减退率均低于60%。同时,在药剂施药后的第5d、第7d药效也相比于其他三种药剂好。
To compare the prevention and control of a variety of jujube gall midge reagent in the actual production process control effects, a field experiment chose four kinds of commonly used agents, using randomized block design, the control effect of comparing different reagents. Experimental results show that the control effect of 4 kinds of medicament to jujube gall midge has longer effect. 30% neem butter has better readily availability and its effect, 3 d, applying pesticide population decline rate and FangXiaoLv are above 80%, and 6000 iu/edged bacillus thuringiensis suspended emulsion, 0.5% matrine agent, 5% efficient chlorine fluorine with ester control effect and loss rate are lower than 60%. At the same time, the reagent 5 d, 7 d after applying pesticide efficacy also compared to the other three kinds of agents.
