| 中文摘要: |
| 研究了45%霜霉威·咪唑菌酮悬浮剂不同剂量对马铃薯晚疫病的防治效果。结果表明: 施用45%霜霉威· 咪唑菌酮悬浮剂对马铃薯晚疫病的防效显著且持久，第3次施药14 d后，对晚疫病的防效达到67.64%～83.78%；马铃薯产量达到19 972.5～23 302.5 kg/hm2，商品薯率高，烂薯率低，增产效果显著。随着供试药剂剂量的增加，对晚疫病的防效差异达到显著水平，但对马铃薯的增产效果差异不显著。45%霜霉威·咪唑菌酮悬浮剂施用剂量以450～675 g/hm 2为宜。 |
| 英文摘要: |
| The effects of different doses of 45% propamocarb·fenamidone SC on potato late blight were studied. The results indicated that the overall control effect of 45% propamocarb·fenamidone SC against potato late blight on the 14th day after 3rd spraying were 67.64%-83.78%. The yield of potato reached 19 972.5-23 302.5 kg/hm 2, with higher marketable tuber percentage and lower rotten tuber percentage. With the increase in fungicide dose, the difference in late blight control effect was significant, but not in the yield increasing effect of potatoes. The suitable application dosage of 45% propamocarb·fenamidone SC were 450-675 g/hm2． |
