Abstract:

[Objective] To screen the effective materials to inhibit cotton verticillium wilt. [Method] The the inhibitory effects of 52 active materials on cotton verticillium wilt were determined using filter paper. The test results were recorded by the classification, visual image and 160× micrographs. [Results] The results show that 14 active materials screened out in this study had remarkable inhibitory effect on. cotton verticillium wilt [Conclusion] The research provided a theoretical basis for screening active materials effective to cotton verticillium wilt and its field control.
