杀虫脒和螟铃畏两种农药都是高效低毒、残效期长的治螟特效农药。过去试验结果,本田施药一次便可解决一代螟害问题,深受群众欢迎。 1974年早造,我们大力推广适期插田,栽培治螟的对策,对压低第一代螟虫密度起到很好的作用。但秧田带螟卵到本田孵化的现象还较普遍,相对地降低了栽培治螟的作用。我们试图利用杀虫脒和螟铃畏残效期长的特点,进行浸秧或在秧田喷药试验,以解决秧苗带卵到本田孵化的问题。
Chlordimeform and Pyrethroid both pesticides are efficient and low toxicity, long-term efficacy of the treatment of pest insects Pesticide. Past test results, Honda pesticide application once can solve the problem of pests, welcomed by the masses. As early as 1974, we vigorously promoted the appropriate field cropping and countermeasures for the cultivation of rice borers, and played a very good role in reducing the density of the first generation of stem borers. However, the phenomenon of hatching eggs in the seedling with the stem borer to Honda is still relatively common, which reduces the effect of cultivation and control of the borer. We tried to use chlordimeform and insecticide amidinate long residual effect of long-term characteristics of the soaking seedlings or spray test in the seedling to solve the hatchling eggs with eggs to Honda.
