多年来在防治麦秆蝇工作中一直采用六六六粉,敌百虫粉剂等防治成虫,由于防治时受不利环境影响较大,加之一年多次防治,费用高昂,残毒积累量大。七八年我们试验用乳剂农药杀卵兼杀成虫的办法进行防治。在麦秆蝇特大发生的情况下,乳剂农药仍有一定的防治效果,试验结果如下,供参考。 Over the years in the prevention and control of the work of straw flies have been using six six six powder, trichlorfon powder and other prevention and control of adults, as a result of adverse environmental control greater impact, combined with many times a year prevention and control, high cost, large residual accumulation. In seven or eight years we test the use of emulsion pesticides to kill eggs and kill adults to prevent and cure. In the case of a large occurrence of straw, emulsion pesticides still have some control effect, the test results are as follows for reference.
