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
