摘要
为了筛选出防治番茄白粉虱的适宜药剂,选用12%哒满·异丙威烟剂、10%吡丙醚乳油、22%螺虫·噻虫啉悬浮剂、22.4%螺虫乙酯悬浮剂、70%吡虫啉水剂、1.3%苦参碱水剂和100亿孢子·g^(-1)白僵菌粉剂共7种杀虫剂,对番茄白粉虱进行药剂处理。运用密闭环境药效试验和田间药效防治试验两种方法,开展番茄白粉虱药效筛选试验。结果表明,在密闭环境下施药后2 d调查,22%螺虫·噻虫啉、12%哒满·异丙威的防治效果最好。在田间进行施药试验显示,22%螺虫·噻虫啉悬浮剂防治效果最好,1 d的防治效果是96.04%,7 d的防治效果是97.18%,14 d的防治效果是95.70%,施药后的速效性和持效性都好于其他处理。70%吡虫啉的速效性和持效性都较差,1 d的防治效果是84.36%,14 d的防治效果是74.10%。而1.3%苦参碱、100亿孢子·g^(-1)白僵菌作为生物制剂,虽然在防治初期的速效性较差,但是持效性好,而且生物制剂无毒,无化学残留,对植物、环境都有安全性,可与22%螺虫·噻虫啉悬浮剂联合用于番茄白粉虱的防治。
In order to screen out the suitable medicament for controlling tomato whitefly,12%Daman·Isoprocarb,10%Pyriproxyfen EC,22%Spirotetramat and Thiacloprid suspending agent,22.4%Spirotetramat suspending agent,70%Imidacloprid water,1.3%Matrine water,10 billion·g^(-1) Beauveria bassiana powder,a total of 7 kinds of pesticides were selected,the tomato whitefly for chemical treatment.Using two methods of drug efficacy test in closed environment and field drug efficacy control test,the screening test of drug efficacy of tomato whitefly was carried out.The results showed that the control effect of 22%Snailworm·Thiacloprid and 12%Daman·Isoprocarb were the best in the investigation 2 days after spraying in a closed environment.The application test in the field showed that the control effect of 22%Snailworm·Thiacloprid suspension agent was the best,the control effect of 1 day after application was 96.04%,the control effect of 7 days after application was 97.18%,and the control effect of 14 days after application was 95.70%.The quick-acting and long-lasting effects were better than other treatments.70%Imidacloprid had poor quick-acting and long-lasting effects,the control effect of 1 day after application was 84.36%,and the control effect of 14 days after application was 74.10%.And 1.3%Matrine and 10 billion·g^(-1) Beauveria bassiana as biological preparations,although the quick-acting effect in the early stage of control was poor,but the lasting effect was good.And the biological preparations were non-toxic and had no chemical residues,which were safe for plants and the environment.It can be used in combination with 22%Spirulina·Thiacloprid suspending agent for the control of tomato whitefly.
