烟蚜(Myzus Persicae Sulz)是烤烟的主要害虫。它使烤烟产量降低,品质变劣。近年来,我们作了多种农药的防治试验,但防效均不理想。1982年,我所与楚雄县烟草公司、通海、江川、澄江和峨山县农科所作了磷胺的田间药效试验。磷胺防治烟蚜试验,以同量乐果对照同时施用。结合生产实际中的用药量,试验分为三组:①磷胺、乐果每亩各163毫升;②190ml/亩;③217ml/亩。三组均设清水喷施为对
Myzus Persicae Sulz is a major pest of tobacco. It reduces yield and quality of flue-cured tobacco. In recent years, we made a variety of pesticide control trials, but the control effect is not satisfactory. In 1982, I and the Chuxiong County Tobacco Company, Tonghai, Jiangchuan, Chengjiang and Asan County, Pesticide made a field effect test of phosphorus amine. Phytophthora pest control test to the same amount of dimethoate control at the same time. Combined with the production of the actual dosage, the test is divided into three groups: ① phosphorus amines, dimethoate 163 ml each; ② 190ml / acre; ③ 217ml / acre. Three groups were set to spray water as right
