稻蓟马是我县水稻主要害虫之一。它不仅为害早稻,而特别是晚稻秧苗受害更为严重。受害稻苗呈现黄白小点,叶片失绿、纵卷、变红,甚至枯焦死亡。以往我县防治稻蓟马一般用乐果、1605混合粉等,虽能控制其为害,但因残效期较短,在整个晚秧期必须隔5～6天防治一次,才能奏效,结果造成用药量、施药次数和成本都相应增加。为解决防治晚秧稻蓟马问题,我们于一九七九年来用3％呋喃丹颗粒剂,深施防治稻蓟马试验。 Rice thrips is one of the major rice pests in our county. It is not only harmful to early rice, especially late rice seedlings suffer more serious. Harm rice seedlings showed yellow and white dots, green leaves, vertical roll, red, and even dead focus. In the past, my county prevention and treatment of rice thrips commonly used dimethoate, 1605 mixed powder, although it can control the damage, but the shorter residual period, the entire late seedling stage must be controlled every 5 to 6 days, to work, resulting in medication Volume, application frequency and cost are increased accordingly. In order to solve the problem of preventing and controlling late rice thrips, we used 3% carbofuran granules in 1979 to deeply control the rice thrips.
