杀虫脒虽是防治水稻螟虫效果较好的药剂,但因残毒、致癌等原因,现在粮食作物上已限制使用,为了寻找替代品种,1981年我们对25％杀虫双水剂进行了防治水稻害虫的试验示范,取得了良好结果。 有关杀虫双的使用技术 1.使用剂量:对几种主要害虫进行的每亩用量3、5、7、9两的剂量试验结果一致表明,每亩用量3两时,防治效果就可达90％左右,剂量增加,药效期显著延长。 2.用药方法:水稻的害虫,经常栖息在植株的中下部,杀虫双是一种内吸输导型药剂,用泼浇、撒毒
Chlordimeform is a good pesticide against rice stem borers. However, due to the causes of residual poison and carcinogenicity, the use of chlordimeform has now been restricted on food crops. In order to find alternative varieties, in 1981, we conducted 25% pesticide-resistant double-agent against rice Demonstration of pests, and achieved good results. The use of insecticidal double the use of technology 1. Dosage: the amount of each of the major pests 3, 5, 7, 9 two doses of the test results show that the amount of 3 per acre 3, the control effect of up to 90 % Or so, the dose increased, significantly longer period of efficacy. 2. Medication Methods: pests of rice, often perched in the middle and lower parts of the plant, insecticidal double is a kind of absorption guide type agent, with pouring, spreading poison
