扑虱灵(有效成分噻嗪酮)是江苏省农药研究所研制而成的防治稻飞虱的新药。为了促成扑虱灵能早日在大面积应用,发挥其特效功能,特对该药的应用技术进行了系统的研究。 试验方法 本试验于1987年在丹阳县农科所完成。供试水稻品种有杂交稻汕优63和晚粳“40316”,以施药方式、施药时期等为主要研究内容。每处理重复三次,随机区组排列。每5天盆拍一次稻飞虱虫量,求出百穴日平均头数,计算防治效果。同时调查稻田蜘蛛量,以蜘蛛量为1,求出蛛虱比,作为衡量对稻田天敌影响的标准。
Puracetam (the active ingredient buprofezin) is a new drug developed by Jiangsu Institute of Pesticide Control planthoppers. In order to promote poplar psychedelic application in a large area as soon as possible to play its special effects function, special application of the drug technology was systematically studied. Test Method This experiment was completed in 1987 in Danyang County Agricultural Science. The tested varieties of rice hybrid rice Shanyou 63 and late japonica “40316”, with the application mode, the application period as the main research content. Each treatment is repeated three times, randomized block arrangement. Every 5 days to shoot a rice planthopper insect population, find the average number of hundred per head, calculate the control effect. In the meantime, the amount of spiders in paddy fields was also surveyed, and the spider mass was 1, and the ratio of spider lice was determined to be the standard for measuring the effect on natural enemies in paddy fields.
