摘要
试验表明,苹果盛花期及谢花后喷施氟吡菌酰胺·戊唑醇35%SC 3000倍液防控霉心病效果最好,防效达59.07%。因是单药剂使用,对病原多样性的霉心病而言,难以达到理想的防治效果;虽然该药剂一定程度降低花序坐果率,但3000倍液还是比较安全,且显著提高果实硬度和可溶性固形物含量;使用后无药害发生。
The results showed that the control effect of fipronamide tebuconazole 35%SC 3000 times solution on mycoheart disease was the best,which was 59.07%.Because it is used alone,so it is difficult to achieve the ideal control effect for mycoheart disease of pathogenic diversity;It can reduce the fruit setting rate of inflorescence to some extent;3000 times was relatively safe,and significantly improved the fruit hardness degree and content of soluble solids;less use and no harm.
