18.6%拌福乙种衣剂防治棉花蓟马的效果研究

【目的】考察种衣剂种类、拌种时间不同的情况下防治棉花蓟马效果。【方法】2009和2010年在新疆喀什地区进行小区试验。【结果】同一种衣剂拌种时间不同对棉蓟马的防治效果不存在显著影响。此外,在5个类型的种衣剂筛选试验中,种衣剂1的平均防效为86.8%,高于种衣剂4和5,显著高于种衣剂6和7。【结论】播种前拌种对棉蓟马的防治效果最好。在棉花生产中,推荐使用种衣剂1(即18.6%拌福乙种衣剂)防治蓟马。

Control Effects of 18.6% Seed Coating of Amicarthiazol & Thiram & Acephate on Thrips of Cotton

【Objective】The prevention effect of different seed dressing time on thrips of cotton and five different kinds of seeds coating were screened.【Method】Plot test in field experiments were carried out in Xinjiang province during 2009-2010.【Result】The results showed that no significant difference was observed between the different seed dressing time.Besides,in all the five different kinds of seed coating treatments,control effect of seed coating one on thrips of cotton was 86.8% on average,and higher than seed coating four and five.Moreover,control effect of seed coating one on thrips of cotton was significantly higher than seed coating five and seven.【Conclusion】Control effect of seed dressing treated with a few time before sowed on thrips of cotton was better than seed dressing treated for a long time.The best control effect of seed coating on thrips of cotton was seed coating one(18.6% Seed Coating of Amicarthiazol & Thiram & Acephate)in agriculture production.
