| 摘要: |
| 通过田间药效试验,对比4种新型杀菌剂防治烟草赤星病的效果,结果表明240克/升氯氟醚菌唑.吡唑醚菌酯乳油、42.4%氟唑菌酰胺.吡唑醚菌酯悬浮剂、400克/升氯氟醚菌唑.吡唑醚菌酯悬浮剂、240克/升氯氟醚菌唑.吡唑醚菌酯乳油4种药剂防效均高于40%菌核净可湿性粉剂,其中400克/升氯氟醚菌唑.吡唑醚菌酯悬浮剂的防效最好,可达83.11±7.10%；为避免烟叶农残超标,可选用以上4种药剂交替使用,防治烟草赤星病。 |

| Abstract: |
| Through field efficacy trials, comparing the effects of four new fungicides on tobacco brown spot disease, the results showed that 240 g/L clofluconazole.pyraclostrobin EC, 42.4% fluconazole.pyraclostrobin Suspension agent, 400 g/L clofluconazole and pyraclostrobin suspending agent, 240 g/L clofluconazole and pyraclostrobin EC, the control effect of 4 kinds of agents are higher than 40% Sclerotin Among the wettable powders, 400 g/L clofluconazole.pyraclostrobin suspension has the best control effect, reaching 83.11±7.10%; To avoid excessive pesticide residues in tobacco leaves, the above 4 agents can be used alternately. |
