粉锈宁,原名三唑酮,是联邦德国80年代初开发的新型杀菌剂。国内近年来开始生产仿制品。该杀菌剂防效佳、杀菌谱广、毒性低,对十多种作物和几十种病害都有良好的防治效果。经我省杂交水稻繁殖制种田的多点试用,防治效果在90%左右,经粉锈宁药防的制种田,黑粉病粒率可控制在1%以下。试用表明,该药的主要特点是内吸性强,施药当天下中雨对药效基本无影响;用药量低,一般每亩只需有效成分7.5～10克;残效期长,每季繁殖制种只需防治一次即可,残效期可达3月之久,
Triadimefon, formerly triadimefon, is a new fungicide developed in the Federal Republic of Germany in the early 1980s. In recent years, China began to produce imitation products. The bactericide has good effect, broad bactericidal spectrum and low toxicity, and has good control effects on more than ten kinds of crops and dozens of diseases. The hybrid rice breeding system in our province by multi-point trial, the control effect of about 90%, the system of triadimefon pesticide farming, black powder disease rate can be controlled below 1%. Trial showed that the drug is characterized by strong absorption, the day when the application of pesticides in the rain on the basic effect was no effect; low dose, generally only the active ingredient per acre 7.5 to 10 grams; long residual period, seasonal reproduction Seeds can be controlled only once, residual validity of up to 3 months,
