自1986到1991年对控制初侵染源防治花生叶斑病进行了试验。结果表明,净化土壤具有显著的防病作用,盆栽控制区较对照区发病3年分别晚70天、15天和5天。7月31日调查,防效依次为100％、91.3％和62.4％,8月30日仍达99.3％、43.1％和30.8％。封锁初侵染源田间防病效果也很明显,播后用杀菌剂与除草剂混合喷洒封锁地面病原菌,8月中旬前各处理效果为2.11％～46.8％,较好的处理为硫酸铜+拉索、百科+乙草胺。
From 1986 to 1991, pest control of primary sources of pest control was tested. The results showed that purifying soil had a significant effect of preventing disease. The potted control area was 70 days later, 15 days and 5 days later than the control area respectively. On July 31, the control measures were 100%, 91.3% and 62.4% respectively, still reaching 99.3%, 43.1% and 30.8% as of August 30. Blockade of the initial source of infection in the field of disease prevention effect is also very clear, after sowing with fungicides and herbicides mixed spray blocking ground pathogens, before the middle of August the treatment effect of 2.11% ~ 46.8%, a better treatment for the copper sulfate + pull Cable, encyclopedia + acetochlor.
