棉花枯、黄萎病是棉花生产中最重要的病害,主要依靠土壤和种子调运进行远距离传播。近年来,由阿拉山口口岸进口棉短绒量不断增加,2008年口岸进口棉短绒货量为3.8153947万t,大部分棉短绒都含有大量的棉籽,可能携带棉花枯萎病菌(Fusarium oxysporum Schl.f.sp.vasinfectum(Atk.)Snyder&Hansen)和棉花黄萎病菌(Verticillium dahliaeK leb)。为保护新疆及我国棉花产业安全,防止棉花枯、黄萎病菌随进口棉短绒中棉籽传入,对进口棉短绒中棉籽是否携带棉花枯黄萎病菌进行了检验。结果,只在进口棉短绒中棉籽上检测到棉花枯萎病病原菌尖孢镰刀菌(Fusarium oxysporum Schl.f.sp.vasinfectum(Atk.)Snyder & Hansen),未检出棉花黄萎病菌。
Cotton withered, Verticillium wilt is the most important disease in cotton production, mainly rely on soil and seed transport for long-distance transmission. In recent years, the import of cotton linter from Alashankou Port has been increasing. In 2008, the volume of imports of cotton linter from ports was 3.8153947 million tons. Most cotton linters contained a large amount of cottonseed and may carry Fusarium oxysporum Schl. f.sp. vasinfectum (Atk.) Snyder & Hansen) and Verticillium dahliae K leb. In order to protect the cotton industry in Xinjiang and China and to prevent cotton yellow and Verticillium wilt infected with imported cotton linter, the test was carried out to see if cotton linter was imported from cotton linters. As a result, Fusarium oxysporum Schl.f. sp. Vasinfectum (Atk.) Snyder & Hansen was detected only on cottonseed imported from cotton linters, and no pathogen of Verticillium dahliae was detected.
