2011—2013年在苹果生产园中使用6种杀菌剂对苹果枝干轮纹病进行了药剂防治试验。结果表明,作为预防药剂,在经历了3年试验之后,健康的枝干仍然没有出现明显的病斑;作为治疗药剂,刮除病斑后用药,甲基硫菌灵对苹果枝干轮纹病的防治效果最好,发病重的枝干经过代森胺、腐植酸+戊唑醇·多菌灵处理也能显著减少病斑带菌率。研究结果表明:对于苹果枝干轮纹病的防治,重在预防;一旦苹果轮纹病菌侵入并定殖之后再用药防治,即使是具有良好内吸作用的杀菌剂也只能起到部分的抑制作用。
In 2011-2013, six kinds of fungicides were used in the apple production garden to control apple round rot disease. The results showed that as a preventive agent, after 3 years of trials, healthy branches still no obvious lesions; as a treatment agent, after the curettage lesion medication, thiophanate-methyl branch of apple blight The best prevention and treatment effect, the incidence of heavy branches after the generation of ammonia, humic acid + tebuconazole · carbendazim treatment can also significantly reduce the incidence of disease spots. The results showed that: prevention and treatment of apple rotten grain rot disease focus on prevention; once the apple ring rot bacteria invasion and colonization and then medication control, even with good systemic absorption of fungicides can only play a part of the inhibition effect.
