摘要：

一种或两种农药相混合研制成农药缓释剂微胶囊和乳油两种剂型, 对林业害虫桑天牛、云斑天牛和松褐天牛成虫及马尾松毛虫幼虫进行了药效、残留、持效性和对人畜毒性等比较试验。在试验基础上也做了缓释乳油的药效和林间防治试验。结果表明, 缓释剂与常规乳油相比, 缓释剂的药效好、持效时间长、毒性低。以SBM-20微胶囊和SBE-20乳油为例, 分别研究了单位时间内的农药释放量和最高农药有效含量, 以及不同剂型在不同时间内农药有效含量的变化规律; 证明了缓释剂微胶囊具有恒定释放和持效的特点。

关键词: 微胶囊, 乳油, 药效

Abstract:

The toxicity, persistence of two kinds of insecticide formulation, microcapsule and emulsifiable concentrate (EC) made from one or two kinds of insecticide, were studied for controlling the larvae of Apriona germari Hope, Monochamus alternatus Hope, Bactocera horsfieldi Hope, and Dendrolimus punctatus Walker. The results showed that either in indoor tests or in field tests microcapsule had better effectiveness, longer duration and lower toxicity to environment than EC. For example, having studied the released quantities in a unit of time and the highest effective contents of SBM-20 microcapsule and SBE-20 emulsifiable concentrate, and the regularity of the change of effective content of insecticide in different formulations and in different times, the authors found that the controlled-release microcapsule had constant release and durable characteristics

Key words: Controlled-release microcapsule, Emulsifiable concentrate, Insecticide effectiveness
