| The formulations and field trails of Abamection.Chlorbenzuron 30% SC were studied in this paper. According to the laboratory bioassay，Abamection.Chlorbenzuron had an obvious synergism effects on Plutella xylostella L. Based on preparation technology and SC technique index, the formula was obtained as-follows:chlorbenzuron TC 29.7%, abamection TC 0.3%, NNO 1%, pesticide emulsifier 1600# 4%, pesticide emulsifier 500# 1%, attapulgite 1% , nekal BX 1.2%, xanthan gum 0.1%, ethylene glycol 5%, silicone 0.3%, and deionized water 56.4%. The results of experimental verification of the formulated product demonstrated that all indexes of Abamection.Chlorbenzuron 30% SC confirmed to the quality technical standards. Field test result showed that the control efficacy of Abamection.Chlorbenzuron 30% SC(180 g/hm2 to 220 g/hm2) against P. xylostella L. was 73.39%~80.19%, which was superior or similar to the efficacy of Abamection 1.8% EC ( 8.1 g/hm2) and Chlorbenzuron 20% SC (225 g/hm2), and the control efficacy could last for 14 days. |
