黄花梨在我县部分乡镇已形成产业种植，但梨网蝽的发生为害十分严重。此虫繁殖快，代数多，老农药甲基１６０５、马拉松不仅防效差，残效短，还存在着对天敌杀伤大，农药残留高的缺点。为筛选高效、低毒、低残留的防治药剂，进行了本试验。１试验设计１． １供试药 １１．５％ Huanghua pear in some counties in our county has formed an industrial plant, but Pear bug occurred very serious harm. This insect propagation fast, algebra and more, the old pesticide methyl 1605, marathon not only poor control effect, short residual, there are still large on natural enemies, pesticide residues high shortcomings. In order to screen high efficiency, low toxicity and low residue control agents, this experiment was carried out. 1 Experimental Design 1. 1 for the test drug 11.5%
