摘要:

为筛选高效、安全的果桑菌核病防治药剂,通过田间试验对不同药剂组合模式的应用效果进行评价。结果表明,各防控区(处理1~处理4)于始花期、盛花期和花末期用药3~4次,经采果盛期多次调查防效均在93%以上;平均单枝果实数、健果率、单枝果实总重等品质指标均优于对照区(处理5);桑果中的农药残留量符合国家规定的最大残留限量标准。建议秋冬季以石硫合剂封园,抓住防治适期选用50%啶酰菌胺WDG 1500倍液+50%异菌脲SC 1000倍液+75%肟菌·戊唑醇WDG 3500倍液的药剂组合进行防控,其他处理的防控模式可作为替换方法进行轮换使用,避免或减缓抗药性的产生。

Abstract:

To screen effective and environmental-friendly fungicides for mulberry sorosis disease control, the control effects of different combination patterns of fungicides were evaluated by field tests. The results showed that the control effect investigated in full fruit period was over 93% by spraying fungicides 3-4 times during the initial flowering period, full bloom period and late flowering period in each control area (treatment 1 to treatment 4). The quality indexes such as the average number of fruits on a single branch, the healthy fruit rate and the total weight of fruits on a single branch were superior to that of the control (treatment 5). The amount of pesticide residue in mulberry fruit conformed to the national standard. It is suggested that the mulberry plantation should be closed with lime sulphur in autumn and winter, and the fungicide combination of 50% diazimide WDG 1500 times solution+ 50% isomicarbazide SC 1000 times solution+ 75% pentazolol WDG 3500 times solution should be applied in the appropriate period. Other control patterns could be used as alternative methods to avoid or slow down the emergence of resistance.
