摘要
黄条跳甲、茎象甲是青海春油菜田的主要虫害。为了探讨国产噻虫嗪30%FS对春油菜田苗期虫害的防效,本试验比较了国产噻虫嗪30%FS、进口噻虫嗪30%SC对黄条跳甲、茎象甲的田间防治效果。2014年和2015年两年试验示范结果表明,国产噻虫嗪30%FS按照10g/0.4kg剂量进行油菜种子包衣,对黄条跳甲的防效可达到73.6%—79.7%,对茎象甲的防效达到71.2%—76.8%。且表现安全,生产成本较进口噻虫嗪低。
Striped flea beetle and weevil is the major pests of Qinghai spring rape field. In order to investigate the domestic thiamethoxam 30% FS of spring rape seedling pest control effect. The experiment compared the domestic thiamethoxam 30% FS,imports of thiamethoxam 30% SC on striped flea beetle,stem weevil field control effect. 2014 and 2015 two years test results show that,domestic thiamethoxam 30% FS according to the dose of 10g/0. 4kg of rape seed coating,the striped flea beetle control effect reached 70. 6% —84. 1%,the stem weevil control effect reached 66. 9%-72. 2%.
