不同剂型嘧菌酯产品对水稻稻瘟病防效比较研究

Comparative Study on Efficacy of Various Azoxystrobin-based Formulations against Rice Blast

本文研究比较了不同剂型、不同厂家的嘧菌酯产品在离体、盆栽和大田条件下对稻瘟病菌的活性,旨在明确不同剂型和厂家的产品在防治水稻稻瘟病方面的效果差异,为该药剂的合理科学使用提供依据。结果表明,不同嘧菌酯产品在离体和活体条件下对稻瘟病菌活性的趋势基本一致,但相同剂型及不同剂型产品之间的防治效果均存在差异。

The efficacy of various azoxystrobin-based formulations against rice blast were compared in vitro, pot and field condition, which is aimed to identify the difference of biological activities between products under different formulations or from different sources, and to provide the basis for the rational control of rice blast in the field. The results indicated that the biological activities for various azoxystrobin-based products presented simliar tendency in both vitro and vivo condition,and that the efficacy difference had been found between different products either under same formulation or different formulations.
