目的:探究几种常见农药水稻田间防治稻水象甲的药效对比。方法:选用20.00%的三唑磷、5.00%的锐劲特以及40.00%的辛硫磷3种常见农药防治稻水象甲,试验地点选为西秀区东屯乡本寨万亩大坝,试验时间为2013年5月6日起,然后,对试验结果进行统计分析。结果:以5.00%的锐劲特45 mL/666.7m2防治稻水象甲的效果最好,在用药后的5 d、10 d,5.00%的锐劲特45 mL/666.7m2防治稻水象甲成虫的防治效率达到了100.00%和91.02%,而40.00%的辛硫磷药后的效率分别为80.12%、90.14%、73.23%。结论:在防治水稻田间稻水象甲时,可以使用40.00%的辛硫磷和5.00%的锐劲特这2种农药交替进行防治,以提高防治效率。
Objective: To explore the efficacy of several common pesticide rice fields in the control of rice water weevil. Methods: Three kinds of common pesticides including 20.00% triazophos, 5.00% fipronil and 40.00% phoxim were used to control the rice water weevil. The test site was selected as the Baishuangwan dam of Dongtun Township in Xiu District, The test time is May 6, 2013, and then the statistical analysis of the test results. Results: The best effect was achieved with 5.00% of fipronil 45 mL / 666.7m2, and 5 mL, 6 d, 5.00% of fipronil 45 mL / 666.7 m2 after treatment The control efficiency of adults reached 100.00% and 91.02%, while the efficiencies after 40.00% phoxim were 80.12%, 90.14% and 73.23% respectively. Conclusion: In the control of rice water weevil, we can control the two kinds of pesticides with 40.00% phoxim and 5.00% fipronil alternately to improve the control efficiency.
