为探索“菊磷”新农药大面积防治稻纵卷叶螟的可行性、可靠性,特进行本试验.6%和12%菊磷乳剂由平乐县化工厂提供,是菊酯类与有机磷复配加增效剂而成的农药.前者设880倍、1000倍,后者设2000倍、3000倍,并设不施药空白对照.每处理重复2次,每小区0、07亩,于药前、药后1天、7天,调查各小区的虫数,每小区调查20丛.并计算虫口减退率及其防治效果.试验结果表明:12%和6%菊磷乳剂对稻纵卷叶螟都具较好的防治效果,药后1天为63.6～B4%,药后7天达78.6～89、1%.各处理间差异不大,其中以12%菊磷乳剂
In order to explore the feasibility and reliability of large scale prevention and treatment of rice leaf roller with “Chrysophyllum” new pesticides, 6% and 12% chrysanthemum emulsion were provided by Pingle Chemical Plant, Phosphorus compound with synergist made of pesticides.The former set 880 times, 1000 times, the latter set 2000 times, 3000 times, and set no blank control.Each treatment repeated 2 times, each district 0,07 acres, In the pre-drug, 1 day after treatment, 7 days, the investigation of the number of insects in each plot, 20 plots per plot and calculate the rate of decline and its prevention and control of insect population.The test results show that: 12% and 6% Leaf roller borer has a better control effect, after 1 day of drug was 63.6 ~ B4%, 7 days after treatment up to 78.6 ~ 89,1% .There was no significant difference between the treatments, of which 12%
