Abstract: Mycelium protein of Verticillium dahliae was used for the production of polyclonal antibodys to V. dahliae, and a indirect ELISA method for specific detection of cotton verticillium wilt was established. The Mycelium protein of V. dahliae could be detected as low as 5 ng/mL at 405 nm. V. dahliae could be quantitively detected in the stem, root, leaf and soil from the diseased cotton plants through this method. Results also showed that amounts of the pathogen from the stems, roots and the soil of the diseased plants were positive correlation to the severity of cotton verticillium wilt. It convinced that the new established Elisa method is a promising technique for early detection and forecast of cotton verticillium wilt.
