苹果斑点落叶病是苹果上的一种主要病害。室内和田间试验证明:12%苯铜水剂对苹果斑点落叶病的防治效果明显优于50%多菌灵可湿性粉剂和50%代森锰锌可湿性粉剂,20%苯杨粉EC的田间防治效果也比代森锰锌好。因此,在防治苹果斑点落叶病时,12%的苯铜水剂可以作为代森锰锌和多菌灵的替代药剂。
Apple spot defoliation is a major disease on apples. Indoor and field tests showed that the control effect of 12% benzene-copper aqueous solution on apple spotted leaf decay was significantly better than that of 50% carbendazim WP and 50% mancozeb WP, 20% Preventive effect is better than mancozeb. Therefore, in the control of apple spot deciduous disease, 12% of benzene bronze water agent can be used as an alternative to mancozeb and carbendazim.
