呋喃丹是一种高效杀虫(线虫)剂,具有胃毒、触杀和内吸杀虫作用,残效期长。国内用于防治水稻害虫已取得显著的防治效果。鉴于棉花害虫对常用农药的抗药性逐年增加,而提高药液浓度和增加喷药次数又会造成杀伤天敌和污染环境等严重问题。1979年开始,我们试用呋哺丹颗粒剂隐蔽施药的办法,防治棉蚜,获得初步成效。每亩用3%呋喃丹颗粒剂3斤,对棉蚜有效控制期可达50天左右,麦收前可以不需喷药治蚜,伏期每亩用呋喃丹3斤拌肥埋施,对伏蚜有效控制期也可达到30天。采取这
Carbofuran is a highly effective insecticidal (nematode) agent with stomach toxicity, contact and systemic insecticidal action and long residual duration. Domestic for the control of rice pests have achieved significant control effect. In view of cotton pest insecticide resistance to commonly used pesticides increased year by year, and increase the concentration of liquid and increase the number of spraying will cause serious damage to natural enemies and polluting the environment. Beginning in 1979, we try furosemide granules concealed pesticides approach to control cotton aphid, to obtain initial results. 3 kg per acre with 3% carbofuran granules, cotton aphid effective control period of up to 50 days before the wheat can be sprayed without spraying aphids, volts per mu with 3 kg carbofuran mixed fertilizer embedding, Aphid effective control period can reach 30 days.
