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.
期刊介绍：
The Journal of Tea Science was established in August 1964, approved by the Publicity Department, CCCPC. Its title was inscribed by Zhu De, the chairman of CCCPC. It was discontinued during the Cultural Revolution in 1966, and it was reissued in August 1984, approved by the State Scientific and Technological Commission.Academicians Chen Zongmao and Liu Zhonghuaof the Chinese Academy of Engineering served as the directors of the editorial board. The Journal of Tea Science is managed by the China Association for Science and Technology,sponsored by the China Tea Science Society and the Tea Research Institute of the Chinese Academy of Agricultural Sciences, and edited and published by the editorial office of the Journal of Tea Science. It is the only one of Chinese core journals in the field of tea science that is included in the core library of the Chinese Science Citation Database.Its Domestic Unified Serial Number is CN 33-1115/S, its International Standard Serial Number is ISSN 1000-369X and its International publication name code is CODEN-CHKEF4. At present, the Journal of Tea Science is a bimonthly publication, published in the middle of the month, with a book size of 16.
