水稻白叶枯病是我省水稻主要病害,每年都有不同程度的发生和危害。当前虽已筛选出一些防治水稻白叶枯病内吸、高效的新药剂,但由于慢性毒性问题未解决,目前还难以投产应用。为寻找高效低毒、来源广、成本低的新农药,我所与省化工研究所协作,从一九七七至一九八一年共测定由省化工研究所提供的新农药382种。一九八○年测定中,发现F_(47)、F_(48)防治水稻白叶枯病效果高于当前推广应用的10％叶枯净可湿粉,并经多次盆栽和田间试验
Rice bacterial leaf blight is the main disease of rice in our province, each year have different degrees of occurrence and harm. Although some new drugs have been screened out to prevent and treat the bacterial suction and high efficiency in rice bacterial blight, the application of the pesticide is still hard to put into operation due to the unresolved chronic toxicity problem. In order to find new pesticides with high efficiency, low toxicity, wide source and low cost, in collaboration with the Provincial Institute of Chemical Industry, we measured a total of 382 new pesticides provided by the Provincial Institute of Chemical Industry from 1977 to 1981. In the 1980 test, it was found that the effects of F 47 and F 48 on the control of bacterial leaf blight were higher than those of the current 10% leaf wettable WP, and after repeated pot and field trials
