摘要： 研究噻虫嗪种衣剂的科学合理施用技术，旨在解决传统施药过程中劳动强度大的问题。2010—2012年，采用田间小区试验，探索噻虫嗪种子处理对水稻秧苗生长的影响及其对稻蓟马的防治效果。试验结果表明，以噻虫嗪不同剂型(70%WS、30%FS)对水稻种子进行包衣浸种或浸种包衣处理后，其抗寒能力明显增强；同时，该药剂对出苗率、成苗率以及对成苗后的水稻秧苗生长具有一定的促进作用。此外，25 g/L咯菌腈FS中加入30%噻虫嗪FS能有效控制稻蓟马为害，播后23~30天的卷尖率为2.00%~24.77%，明显低于不施药处理(41.33%~88.87%)。

Abstract: To solve the labor- intensive problem during traditional pesticide application, a scientific and reasonable application technology of thiamethoxam seed coating formulation was studied. Field plot experiments were conducted to investigate effects of thiamethoxam seed treatments on the rice thrips, Chloethrips oryzae (Williams) and seedling growth of rice in 2010- 2012. The results showed that high cold tolerance of rice could be achieved, when different formulations of thiamethoxam, such as 70% WS and 30% FS were coated for pre-soaked or post-soaked of rice seeds in water. As the same time, simulation roles for emergence rate, seedling rate and seedling growth of rice were observed using above insecticide. Furthermore, perfect control on C. oryzae could be achieved by 25 g/L fludioxonil FS plus 30% thiamethoxam FS; the leaftip rolling rate was 2.00%-24.77% and significantly lower than that of untreated, which was 41.33%-88.87%, at 23-30 days after rice direct-seeded.
