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。
Through laboratory and field experiments, macromolecule organic acid complex alkali copper has a good bactericidal effect and remarkably improves the safety of crops. The macromolecule organic acid compound alkali copper 300, 400 and 500 times, Bordeaux mixture (1: 1) 300 times, green suspension 300 times and succinate 300 times, The inhibitory rates of Sporoderm germination were 93.5%, 85.2%, 65.4%, 65.2%, 85.9% and 75.6%, respectively, Were 72.6%, 65.3%, 51.0%, 42.3%, 72.3% and 60.6% respectively. The control effects of field trials on apple ring disease were 91.4% and 70%, respectively. 4%, 64.9%, 53.0%, 81.5% and 73.9%, respectively. Similar results were found in the control of tomato early blight. By testing eight kinds of crops such as apples and cucumbers, macromolecule organic acid complex alkali copper was safer to the crops tested.
