一、前言纹枯利,化学名称:N-(3,5二氯苯基)丁二酰亚胺,结构式据日本报导称,对水稻纹枯病、稻瘟病、胡麻叶斑病及蔬菜、花卉等一些病害有良好效果,尤以对水稻纹枯病报导为多,而对油菜菌核病则甚少。我们于1972年合成,自测原粉(含量90%)LD_(50)〔小白鼠、雄、口服〕741.3毫克/公斤。曾以15%、20%乳剂和25%、40%、50%可湿粉等剂型供有关省市进行药效试验。先是以水稻纹枯病为重点进行试验,1973年开始,以油菜菌核病为重点进行试验。1974年,在批林批孔运动的强大推动下,我们提供了2.4吨40%纹枯利可湿粉供14个省市进行试验,
I. INTRODUCTION Ribicula, its chemical name is N- (3,5-dichlorophenyl) succinimide. According to reports in Japan, it is reported that it is effective against rice sheath blight, rice blast, flax leaf spot and vegetables, flowers Some other diseases have a good effect, especially in the report of rice sheath blight as much, but very few on sclerotinia. We synthesized in 1972, self-test the original powder (content 90%) LD_ (50) [mice, male, oral] 741.3 mg / kg. Had 15%, 20% emulsion and 25%, 40%, 50% WP and other dosage forms for the provinces and cities for efficacy tests. First rice sheath blight as the focus of the test, beginning in 1973 to rape sclerotinia focus on the test. In 1974, under the strong impetus of the campaign of criticizing Lin Pi-kong, we provided 2.4 tons of 40% grain licorice powder for testing in 14 provinces and cities,
