枸杞炭疽病药剂防治药剂筛选

为有效防控厚皮甜瓜细菌性果斑病的发生,提出一套综合防控技术,通过田间开展各单项防控技术的重要性试验,建立标准化综合防控技术体系.结果表明:各单项技术可提高对细菌性果斑病的防效.与对照相比,72％农用硫酸链霉素可溶粉剂浸种可使防效提高16％,病果率降低3％;标准化喷药能使防效提高17％以上,病果率降低3.1％;整枝打杈前后进行防控能使防效提高39％以上;厚皮甜瓜整个生育期不浇水,能够减少病果的数量;在此基础上组装而成的标准化综合防控技术体系防效达89.2％以上,病果率仅为2％.

Screening of fungicides for Colletotrichum gloeosporioides control

A set of integrated management techniques were proposed for the effective control of bacterial fruit blotch in muskmelon in this paper, and the importance of every prevention technology were proved and standardized through field test. The results showed that each single technology could increase the control effect on bacterial fruit blotch. Compared with the control, Streptomycin 72% SP soaking could increase the control efficacy by 16% and decrease diseased fruit rate by 3%. Standard spraying pesticides could increase the control efficacy by more than 17% and reduce the diseased fruit rated by 3.1%. Spraying pesticides before and after pruning play fork could increase the control efficacy by over 39%. No watering during the whole growth period of muskmelon could also reduce the number of diseased fruit. Finally, standardized comprehensive prevention and control technology system were assembled based on the control techniques mentioned above, the average control efficacy reached more than 89.2% and the diseased fruit rate was only 2%.
