自80年代后期,我国开始试验并逐步推广应用扑虱灵防治水稻飞虱,已经取得了极为明显的防治效果,它不仅表现灭虫效果高,残效期长,且毒性低,对天敌安全,是目前防治稻飞虱较为理想的药剂。至1992年为止,我国广东、广西、福建、江西、湖南、湖北、安徽、江苏、浙江、上海等10省、市的统计,应用扑虱灵的面积达9304万亩。预计今后几年还会有更大的发展。但是勿容置疑,扑虱灵还存在着杀虫谱单一,前期作用效果慢等问题,加之在稻飞虱发生期常拌有纹枯病等病害发生,这就要求以扑虱灵为主混配其他农药,以达到一次施药防治多种病虫的目的。据我们 Since the late 1980s, our country began to test and gradually popularize the application of poppy to control planthoppers. It has achieved extremely obvious control effect. It not only shows high pest-killing effect, long residual period, low toxicity, It is the ideal agent for controlling planthoppers. Until 1992, the statistics and applications of Phylloxera in Guangdong, Guangxi, Fujian, Jiangxi, Hunan, Hubei, Anhui, Jiangsu, Zhejiang and Shanghai in the 10 provinces and municipalities reached 93.04 million mu. Expected in the next few years there will be more development. However, there is no doubt that there is a single insecticidal spectrum of prophase spirits, the early effect of slow and other issues, coupled with the occurrence of rice planthopper often mixed with sheath blight and other diseases occur, which requires the use of propafenone-based With other pesticides, in order to achieve the purpose of a variety of pest control.
