鉴于水稻细条病和白叶枯病的病原菌属不同致病变种，为减少用药的盲目性，收集国内外５种农药，分别对其进行防治试验。平皿抑菌试验结果，４０％多丰农和９０％乙霜青对水稻细条病和白叶枯病病原菌产生抑菌作用，抑菌环宽度分别为１０ｍｍ和３ｍｍ。３ａ室内盆栽测定结果，多丰农对细条病和白叶枯病平均药效分别为６６．１９％和６６．２９％；乙霜青防治细条病效果为５７．７２％～６３．８５％，高于叶青双防效（４１．１４％～５４．３４％），差异显著；叶青双对白叶枯病的防效为６３．９０％～７４．５４％，高于乙霜青防效（４７．７０％～５７．４８％），差异显著；加瑞农和可杀得对水稻细条病和白叶枯病效果均差。１９９３～１９９４年田间小区试验结果，乙霜青防治细条病的防效比叶青双高出１７．４～３８．４个百分点。小区及示范结果表明，乙霜青是一种防治细条病的有效药剂，始病期（病指在５以下）施药，防效可达８０％以上。 In view of the pathogenic bacteria of rice stripe and bacterial leaf blight are different pathogenic species, in order to reduce the blindness of the drug, collecting five kinds of pesticides at home and abroad, respectively, for its prevention and control tests. Bacteriostasis test results showed that 40% Dafengnong and 90% Dangqingqing had bacteriostatic effects on the pathogens of rice stripe disease and bacterial leaf blight. The antibacterial ring widths were 10mm and 3mm, respectively. 3a indoor pot test results, Dufeng farmers on the average tuberous and bacterial blight efficacy were 66.19% and 66.29%; b cream fry prevention and control of thin strip disease effect of 57.72% ~ 63.85% (41.14% ~ 54.34%), the difference was significant. The control effect of the double leaf blight of Yeqing was 63.90% ~ 74.54%, which was higher than that of the control % ~ 57.48%), significant difference; Garrett and kill can have a poor effect on rice stripe and bacterial blight. Field trials from 1993 to 1994 showed that the control effect of bsuchuang on leaf streak was 17.4-38.4% higher than that of Ye Qingshuang. Community and demonstration results show that b cream green is an effective control of thin strip disease, the onset of disease (disease means below 5) spraying, control effect of up to 80%.
