Abstract

The bioactivity of an organic synergist (supplied by the Institute of Pesticide Formulation Technology, Gurgaon, India) was assessed to establish the enhanced efficacy of Neem kernel Aqueous extract (NKAE) and three recommended acaricides such as Fenpyroximate 5 EC, Ethion 50 EC and Spiromesifen 22.9 SC against one of the major tea pest, red spider mite under laboratory conditions. The selected three different acaricides, with recommended doses were tested and their efficacies were compared with that of NKAE. The study revealed that organic synergist enhanced the efficacy of Neem kernel powder (NKP) (even it is @ 2.5% NKP) to the tune of almost 45% and enhanced the efficacy of each acaricides to the tune of almost 20-40% compared to the individual treatments which could be further exploited for reducing the pesticide load on tea.

有机增效剂对印度楝仁水提物(NKAE)和3种推荐杀螨剂防治茶红蜘蛛螨(Oligonychus coffae)的生物活性研究

在实验室条件下，对一种有机增效剂(由印度Gurgaon农药配方技术研究所提供)的生物活性进行了评估，以确定印度楝仁水提物(NKAE)和三种推荐的杀螨剂(Fenpyroximate 5 EC、Ethion 50 EC和Spiromesifen 22.9 SC)对茶叶主要害虫之一红蜘蛛螨的增强功效。选择3种不同的杀螨剂，按推荐剂量进行试验，并与NKAE进行药效比较。研究表明，有机增效剂将印度楝仁粉(NKP)(即使是@ 2.5% NKP)的功效提高了近45%，与单独处理相比，每种杀螨剂的功效提高了近20-40%，这可以进一步用于减少茶叶的农药负荷。
