摘要
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。
prevention and cure peanut leaf spots by controlling primary infection source had been studied during 1986～1991. The results verified the soil purification had significant effect on preventing the disease. The pot culture experiment showed the disease occur 70,15 and 5 days later respectively in the controlling area than the control,and the controlling effect recorded on 30,July was 100%,91.3% and 62.4% respectively. Until 30, August, the controlling effect was still kept at 99.3%, 43.1% and 30.8%, The protective effects of controlling primary infection source were also apparently in the field, Each treatment spraying the mixture of germicide and herbicide to blockade the ground pathogen germicide proved to be eddective before 10,August. The effect ranged from2.11% to 46.8L%.Better treatments are CuSO_4+Lasso,Baycor+Acetochlor.
