Effect Evaluation of Pymetrozine on Controuing Empoasca vitis and Its Pesticide Residues Analysis
摘要
Abstract
In order to determine the field control effect , degradation half -life and final residues of py-metrozine, solve the problems of pest damage to tea plants and tea quality safety , the field experiments were carried out .The results showed that 25%pymetrozine SC controlled the Empoasca vitis damage effectively with good availability and persistence , and the control effect was above 75%.The degradation half -life of py-metrozine as 3.0 days and 6.5 days respectively in fresh tea and soil .The residue of 25%pymetrozine SC 200 mg a.i./L in dry tea was 0.058 mg/kg after 7 days of spraying twice , while that it was 0.045 mg/kg after 7 days of spraying once .关键词
