摘要
为有效测定75%肟菌戊唑醇WG(拿敌稳)对水稻稻曲病的防治效果、施药时间、使用方法及对水稻的安全性等,开展了该药剂的田间药效试验及应用技术研究。结果表明:75%肟菌戊唑醇WG(拿敌稳)3 000倍对水稻稻曲病有很好的防治效果,连续2次用药后11 d和23 d的防效分别达83.7%和82.3%,极显著优于对照药剂4%井冈霉素AS 250倍的防效,其不但持效期长、安全性好,而且增产效果极显著优于4%井冈霉素AS 250倍,比清水对照增产8.8%,因此在生产上具有良好的推广应用前景。
To verify the efficiency of 75% Trifloxystrobin.Tebuconazole WG in rice false smut control, and its application time, usage and safety, etc., field trials of the pharmaceutical and application technology researches were carried out. The results showed that 75% Trifloxystrobin.Tebuconazole WG 3 000 times had good control effects on rice false smut, and after twice treatments, the control efficiency at 11 d and 23 d reached 83.7% and 82.3%, respectively, which were significantly better than that of the agent of 4% Jinggangmycin AS 250 times. This pesticide had not only long duration and safety, but also its yield effects were significantly better than that of 4% Jinggangmyein AS 250 times. Also, compared with the water, its yield was increased by 8.8%. So, this insecticide had good application prospects in agricultural production.
