摘要
叶枯灵(原名渝-7802,简称BHD)是一种新型有机硫杀菌剂。室内测定表明,叶枯灵500—1000ppm,对白叶枯病菌有显著抑制作用。田间小试与中试,采用以上浓度喷撒2—3次,每隔7—10天喷1次,防治效果达80％以上,保产率17％以上,效果接近敌枯双,显著优于叶枯净。
BHD is a new organosulfur fungicide.Laboratory tests of the abilityto inhibit bacterial growth of bacterial blight in nutrient agarmedium indicated that it showed inhibition at 500 to 1000 ppm.Thecontrol effect of about 80% was obtained by spraying 2 to 3 times (i.e;7 to 10 days/each time) with 25% BHD(W.P.).Sample or productin experimental fields of irrigated rice and the grain yield increasedup to 17% in average.Comparing with TF130 of 125ppm,the effectof BHD was not markedly different but was much higher thanPhenazine at 500 ppm.
