摘要
针对西花蓟马对京郊保护地彩椒危害严重的现况,选取市售的0.6%苦参碱水剂、n5%印楝素乳油、l%虫菊·苦参碱微囊悬乳剂、1.5%除虫菊素水乳剂、7.5%鱼藤酮乳油等5种植物源药剂和1%甲氨基阿维菌素苯甲酸盐微乳剂、1.8%阿维菌素乳油、2%高氯·甲维盐微乳剂、6%乙基多杀菌素悬乳剂等4种非植物源药剂,进行田间药效筛选。结果表明:在试验观察期,施药后1、3、7d,5种植物源药剂校正防效由34.8%~50.0%上升至59.2%~68.6%,防效随着处理时间的延长表现出增强的趋势,药效呈现较好的持效性;4种非植物源药剂在药后3d的校正防效均达64%以上,对西花蓟马表现出较好的速效防治效果,但防效随时间延长表现出减弱的趋势,施药后第7天,除1.8%阿维菌素乳油之外,非植物源药剂的防效均显著低于植物源药剂防效。
Five commercial botanical insecticides ( 1.5% pyrethrin, 7.5% rotenone, 0.5% azadirachtin, 0.6% matrine and 1% pyrethrin· matrine ) and other 4 non-botanical insecticides ( 1% emamectin benzoate, 1.8% abamectin, 2% beta-cypermethrin · emamectin benzoate, 6% spinetoram ) were chosen to conduct field pesticide effect experiment on 1, 3, 7 days after spraying so as to screen appropriate insecticides against Frankliniella occidentalis ( Pargande ) of greenhouse color sweet pepper, which caused serious damage in outskirt of Beijing. The result Showed that the correction control efficiency of 5 botanical insecticides ranged from 34.8%-50.0% to 59.2%-68.6% during test, which showed an increasing trend along with the increasing of spraying time during this experiment and showed good persistence effect. The control efficacy of 4 non-botanical insecticides reached 64% on day 3, which showed good rapidly available effect and weakening tendency with increasing time against western flower thrips. The control efficiency of botanical insecticides except 1.8% abamectin were significantly higher than that of non-botanical insecticides on day 7 after spraying.
