Experiments with applications of NaCl (560 and 1,120 kg/ha) and lime (6,719 kg/ha) were conducted in asparagus fields in commercial production (one healthy and one exhibiting symptoms of early decline), and an experiment with NaCl (1,120 kg/ha) was conducted in a badly declined research field at Michigan State University from 1998 to 2000 to determine whether these treatments control Fusarium crown and root rot of asparagus. Growth chamber and greenhouse studies were conducted to test the ability of alternative forms (CaCl, NHCl, and MnCl) of chloride salt to reduce disease caused by F. oxysporum f. sp. asparagi and F. proliferatum. NaCl applications increased yield and fern health in the research plot, but not in commercial fields. Soil tests in these fields indicated that NaCl did not decrease levels of calcium, magnesium, or potassium, and did not affect pH. In growth chamber studies with asparagus seedlings in Hoagland's agar test tubes, and in greenhouse studies with asparagus seedlings in soil, none of the alternative forms of chloride salt tested were more effective than NaCl in controlling Fusarium crown and root rot.
在商业化生产的芦笋田（一块健康田和一块出现早期衰退症状的田）中开展了施用氯化钠（560和1120千克/公顷）和石灰（6719千克/公顷）的试验，1998年至2000年在密歇根州立大学一块严重衰退的研究田中开展了施用氯化钠（1120千克/公顷）的试验，以确定这些处理措施能否控制芦笋镰刀菌冠腐病和根腐病。进行了生长室和温室研究，以测试氯化物盐的替代形式（氯化钙、氯化铵和氯化锰）减轻尖孢镰刀菌芦笋专化型和层出镰刀菌引起的病害的能力。在研究地块中施用氯化钠提高了产量和嫩茎健康状况，但在商业田块中未出现这种情况。这些田块的土壤测试表明，氯化钠并未降低钙、镁或钾的含量，也未影响pH值。在使用霍格兰琼脂试管中的芦笋幼苗进行的生长室研究以及使用土壤中的芦笋幼苗进行的温室研究中，所测试的氯化物盐的替代形式在控制镰刀菌冠腐病和根腐病方面均不如氯化钠有效。
