室内毒力测定结果表明,防腐灵( 复配杀菌剂) 对栗实黑腐病菌孢子萌发和菌丝生长的抑制均为100 % ,并能延缓病菌抗药性的产生。3 年的防治试验表明,防腐灵对栗实病害的防效(71 .2 % ~93 .7 % ) 明显优于退菌特(14 .9 % ~65 .7 % ) 。
The results of indoor toxicity test showed that the anti-rot fungus (compound fungicide) inhibited the spore germination and mycelial growth of the black-rot fungus by 100%, and could delay the emergence of the pathogenic bacteria. Three years of control tests showed that the anti-corrosion spirit of chestnut disease prevention and control (71.2% ~ 93.7%) was significantly better than the withdrawal of special (14.9% ~ 65.7%).
