According to the laboratory bioassay, there was an obvious synergism effect on Plutella xylostella (L.) mortality, by means of tests of virulence and surface active agents, the formulation of abamec- tion·destruxin A 2% SC was determined. The results of experimental verification of the formulated product demonstrated that all indexes of abamectiondestruxin A 2% SC confirmed to the quality 2 2 technical standards.
