鉴于棉蚜(Aphis gossypii Glover)对常用的有机磷酸酯类杀虫剂抗药性目益严重,而提高药液浓度和增加喷药次数招致杀伤天敌及污染环境,我们于1977年研制了属氨基甲酸酯类的呋喃丹微粒剂,采取隐蔽施药,用于拌棉种治蚜,已初获成效。每亩用3％呋喃丹微粒剂三斤,对棉蚜有效控制期达55天左右,较国外的3％呋喃丹颗粒剂药效高,麦收前可不需喷药治蚜。此药加工和施用方便,且对棉花生
In view of Aphis gossypii Glover resistance to commonly used organophosphate pesticides serious, and increase the concentration of liquid and increase the number of spraying lead to natural enemies and polluting the environment, we developed in 1997 is a carbamate Carbofuran ester granules, to take a concealed application, for cotton seed treatment of aphids, has achieved initial success. 3 mu of carbofuran granules per mu with three pounds of cotton aphid effective control period of about 55 days, 3% carbofuran granules than foreign high efficacy, before the wheat harvest without spraying aphids. The drug processing and application of convenience, and on cotton
