The number of veriticillium dahliae in cotton had greatly difference in vertical distribution of soil. More 90% of them distributed over principally 0-40 centimetre depth soil Layer. In horizontal distribution of soil, distribution model of verticillium dahliae in cotton varied from the aggregation distribution to the uniform distribution in disease plants, the number of cotton verticillium dahliae in disease organizations of plant was in turn leaves>trunk>floral branches.
