| 中文摘要: |
| 葱蓟马Thrips tabaci Lindeman是一种世界性农业害虫，为明确3种纳米缓释剂农药对葱蓟马的防治效果，开展了田间药效评价试验。结果表明，0.7%甲维盐纳米缓释剂（NR）和5%甲维盐微乳剂（ME）对葱蓟马的速效性和持效性较好，3~14 d的防效均达到90%以上；10%高效氯氟氰菊酯NR和5%高效氯氟氰菊酯ME对葱蓟马的速效性较好，药后3 d，防效均达90%以上，但后者的持效性稍弱；2%呋虫胺NR和20%呋虫胺可溶粒剂（SG）的速效性和持效性较好，3 d和14 d的防效均达85%以上。上述结果表明，甲维盐、高效氯氟氰菊酯和呋虫胺适用于田间葱蓟马的防治；相同或更低剂量下，纳米缓释剂型与传统剂型农药的效果相当或者更优，显示出良好的应用前景。 |
| 英文摘要: |
| Thrips tabaci Lindeman is an important agricultural pest around the world. A field trial was conducted in order to evaluate the control efficacy of three controlled release nanopesticides against T. tabaci. The results showed that 0.7% emamectin benzoate nano-relievers (NR)and 5% emamectin benzoate microemulsion (ME)provided excellent quick and persistent effect to T. tabaci and the control efficacy was over 90% 3~14 days post spraying. Similarly, the quick efficiency of 10% lambda-cyhalothrin NR and 5% lambda-cyhalothrin ME to T. tabaci was high and the control efficacy was over 90% 3 days post spraying. However, the persistency of 5% lambda-cyhalothrin ME was relatively lower than the former. The quick and persistent effects of 2% dinotefuran NR and 20% dinotefuran water soluble granule (SG)were high to T. tabci and the control efficacy was over 85% 3~14 days post spraying. The results indicated that three controlled release nanopesticides of emamectin benzoate, lambda-cyhalothrin and dinotefuran could be used against T. tabaci in the field. At the same or lower dosages, the controlled release nanopesticides had similar or ever higher control efficacy, which showed an ideal application with bright prospect in the future. |
