根据近两年来对江苏省各棉区调查的结果,江苏省棉花苗期根病以炭疽病和红腐病为主,棉立枯病除在个别地区发病较重外,多数地区较轻。为了进一步验证目前生产上所用农药的效果,并补充几种新的药剂作为试验材料,为防治棉花苗期根病提供新的途径。 According to the survey results of cotton fields in Jiangsu Province in the past two years, anthracnose and red rot are the main diseases of cotton seedling in Jiangsu Province. In addition to the serious disease in some areas, cotton blight is relatively light in most areas. In order to further verify the effectiveness of the pesticides used in the production and to add several new agents as test materials, it provides a new way for the prevention and treatment of cotton seedling root disease.
