摘要
马铃薯疮痂病已成为威胁牡丹江地区马铃薯生产的重要病害。试验通过对新型土壤颗粒剂的研制,确定了2种颗粒剂配方,并采用随机区组法对马铃薯疮痂病进行防治,解决牡丹江地区马铃薯疮痂病在大田防治中的空白。试验结果表明,利用配方CJ-1进行土壤处理对疮痂病的防治效果明显好于配方CJ-2,感病率及病情指数显著降低,同时结合播种前用甲托加百菌清与石膏粉拌种处理防效最佳。
Potato scab has become a serious disease in Mudanjiang potato production. In this experiment, the new soil granules were studied to control potato scab. Two granular formulations were determined which fill the blank of potato scab prevention in Mudanjiang area. Randomized block design was adopted in the prevention test. The results showed that using CJ- 1 formula for soil treatment was better than the CJ- 2 formula for prevention of potato scab. Both incidence and disease index decreased significantly. The soil granule combined with thiophanate methyl, chlorothalonil and gypsum powder that dressed potato seeds had the best control effect.
