摘要： 通过室内和田间试验，高分子有机酸复合碱式铜具有较好的杀菌效果，对作物的安全性明显提高。以高分子有机酸复合碱式铜300、400和500倍液、波尔多液（1∶1）300倍液、绿得保悬浮剂300倍液和琥胶肥酸铜300倍液，室内测定对苹果轮纹病孢子萌发抑制率分别为93.5%、85.2%、65.4%、65.2%、85.9%和75.6%,对苹果轮纹病菌丝生长抑制效果分别为72.6%、65.3%、51.0%、42.3%、72.3%和60.6%,田间试验对苹果轮纹病的防效分别为91.4%、70.4%、64.9%、53.0%、81.5%和73.9%,防治番茄早疫病的试验也有相似的结果。通过对苹果、黄瓜等8种作物进行试验，高分子有机酸复合碱式铜对所试作物均较安全。

Abstract: Laboratory and field experiments showed that high molecular organic acid ligation basic copper sulfate is a better fungicide,and is safe to most crops.The control effect of high molecular organic acid ligation basic copper sulfate diluted to 300,400,500 times,Ludebao diluted to 300 times,Hujaofeisuantong diluted to 300 times were tested.The results showed that the effect of inhibiting the germination of spore of A.mali is 935%,852%,654%,652%,859% and 756% respectively,and the inhibition rate of hyphae growth of A.mali is 726%,653%,510%,423%,723% and 606% respectively.The control effect is 914%,704%,649%,530%,815% and 739% respectively in field experiment.The test effect to A. solani is similar to A.mali. It is safe to the 8 test crops including apple and cucumber in field experiments.
