摘要
安索菌毒清室内毒力测定表明:该药剂对苹果腐烂病孢子有很强的杀灭能力,浓度等于或高于1ppm时,病菌孢子不能发芽。抑菌中量ED_(50)为19.19±1.64ppm,且残效期达45天以上。田间试验表明,用5％安索菌毒清50～100倍液,涂抹刮治后的病斑2次,治愈率达100％;病斑割条后涂药2次,治愈率达96.49％～100％;用5％安索菌毒清500倍液作铲除剂,初冬或早春喷大枝主干,预防效果达90％以上。
The Jun Du Qing toxicity test in the laboratory showed that the germicidal action was well to apple canker spore. The canker spore didn′t germination concentration of the jun du qing 1ppm or higher than 1ppm.ED_(50)=19.19±1.64ppm.The residual effect was more than 45 days. Field experiments was conducted, that the control efffect of 50 fold or 100 fold dilutions of Jun Du Qing with the scrapping method or the cutting method was 100%;94.6%～100%.When the winter or spring comming, with 500fold dilutions of Jun Du Qing root out pathogenic bacteria in the fruit tree, The prevent effect was 90%.It is believed that the commonly used chemical fungieide Asometa can be replacd with the Jun Du Qing in apple canker control.
