| 摘 要： | 科学合理的施药技术对提高药效与减少用药量至关重要。2009年，氯虫·噻虫嗪防治水稻稻纵卷叶螟、二化螟的田间试验结果表明，40%氯虫·噻虫嗪水分散粒剂能有效防控以上2种虫害且持效性好。同一剂量下，药后7 d的防效受喷头与用水量的影响较大，药后14 d喷雾器、用水量显著制约药效，药后21 d各因素对防效影响无规律性。同一药械（喷雾器类型、喷头型号）下，用水量、剂量和助剂对该药剂防治上述水稻螟虫的作用依次递减。 |

| Abstract: | A scientific and reasonable application technology is very important to increase control efficacy and reduce usage volume of pesticide. Field experiments were conducted to control rice leaf-roller, Cnaphalocrocis medinalis and striped stem borer, Chilo suppressalis with 40% chlorantraniliprole·thiamethoxam WG in 2009. The results showed that perfect control and excellent persistent effect of two rice stem borers could be achieved with above insecticide. When same doses of 40%chlorantraniliprole·thiamethoxam WG were applied, first of all, control efficacy was extremely affected by nozzle and usage volume of water within 7 d after treatment. Furthermore, during the period of another 7 d, the impact of sprayer and usage volume of water were significant for it. Lastly, there was not obvious on influence of usage volume of water, dosage and adjuvant at the end of 21 d after treatment. However, when 40% chlorantraniliprole·thiamethoxam WG was used to control C. medinalis and C. suppressalis through same sprayer and nozzle types, the role of these three effectors on effectiveness was decreased in turn. |
