科学使用化学农药防治有害生物至今还是植保工作上的一种重要手段,为了达到保护茶树免受病虫的为害,确保茶叶持续高产优质的目的,需要不断地发现新的有效药剂,或改善药剂的应用而提高效果。随着高效低毒的化学农药的发展,为筛选适合于茶园使用的高效低毒低残留的新农药,已成为茶树植保工作中极待解决的问题。今年我们根据全国新农药试验网的布置,在供药单位的大力支持下,遵照毛主席“一切经过试验”的教导,在浙江余杭潘板桥对当前茶叶生产中为害较严重的茶叶象甲、茶尺蠖进行了95％杀螟丹、50％杀螟丹、75％乙酰甲胺磷(粉剂)、25％
The scientific use of chemical pesticides to control pests is still an important means of plant protection work. In order to achieve the goal of protecting the tea tree against pests and diseases and ensuring the continuous high yield and quality of the tea, it is necessary to continually find new effective agents or improve medicaments Application and improve the effect. With the development of chemical pesticides with high efficiency and low toxicity, new pesticides with high efficiency, low toxicity and low residue, which are suitable for tea plantations, have become a problem to be solved in plant protection of tea plants. This year, according to the layout of the national new pesticide trial network and with the vigorous support of the drug suppliers, following Chairman Mao’s “all-tested” teaching, we found that in Panhangqiao, Zhejiang Province, tea weevils harming more serious current tea production, Tea scrofa was tested for 95% Cartap, 50% Cartap, 75% Acephate (powder), 25%
