摘  要:
为验证国产吡唑醚菌酯对苹果炭疽叶枯病的防效,2018年开展田间药效试验。结果表明,125 g/L 25%吡唑醚菌酯悬浮剂对苹果叶片和果实上炭疽叶枯病的防效均达到97%以上,0.5%倍量式波尔多液的防效均在95%以上,两者无显著差异;43%戊唑醇悬浮剂和3%多抗霉素水剂防效较差。建议交替使用吡唑醚菌酯和波尔多液,控制吡唑醚菌酯的用量和频次,以延长其使用寿命。

摘  要:
In order to verify the efficacy of domestically-made pyraclostrobin on Glomerella leaf spot of apple, field trail was carried out in 2018. The results showed that the control effect of 125 g/L pyraclostrobin 25% SC on protecting leaf and fruit of apple were over 97% respectively, and 0.5% multi-type bordeaux mixture were above 95% respectively. There was no significant difference between pyraclostrobin and bordeaux mixture on control effect. Tebuconazole 43% SC and polymycins 3% AS were less effective. Pyraclostrobin was recommended to be used with bordeaux mixture alternately, for reducing the amount and frequency of pyraclostrobin to prolong its service life.
