2015~2016年在红枣生产园中使用9种杀菌剂对红枣黑腐病进行了药剂防治田间试验。结果表明,作为预防药剂,在经历了2年试验后,枣园仍然没有出现明显的病果。作为提前治疗药剂,预防和防治结合用药,30%戊唑醇+20%咪鲜胺对红枣黑腐病治疗效果最好,百菌清、森锰锌、70%甲托处理也能显著减少病果数量。研究结果表明,红枣黑腐病的防治重在预防为主,在8月10日(进入白熟期之前)左右开展预防效果比较明显。
From 2015 to 2016, nine kinds of fungicides were used in the jujube production garden to conduct field trials on the chemical control of jujube black rot. The results show that, as a preventive agent, after two years of trials, jujube orchard still did not show obvious consequences. As an early treatment agent, combination of prophylaxis and prevention and treatment, 30% tebuconazole + 20% prochloraz had the best treatment effect on jujube black rot. Chlorothalonil, mancozeb and 70% methotrexate treatment also significantly reduced disease Number of fruit. The results show that the prevention and treatment of jujube black rot is mainly prevention, and the preventive effect is obvious on August 10 (before entering the white maturity period).
