用Rhizoctonia solani Kuhn接种的糖甜菜(Beta vulgaris L.)田间试验证明,高剂量氮肥对丝核菌根腐病有轻微益处,但实际上并非有重要的影响。现代农药灭草特、涕灭威和杀线虫熏蒸剂对根腐病的发病程度并没有实际影响。从而,这些现代农药和氮肥水平既不能强化,也不能抑制糖甜菜根腐病的发展。 Field trials of sugar beets (Beta vulgaris L.) inoculated with Rhizoctonia solani Kuhn demonstrated that high doses of nitrogen fertilizers have a slight beneficial effect on root rot of Rhizoctonia solani but in fact they are not of significant importance. Modern pesticides Metabolite, aldicarb and nematicidal fumigants have no practical effect on the incidence of root rot. Thus, these modern pesticides and nitrogenous fertilizers neither enhance nor inhibit the development of sugar beet root rot.
