In soil under alfalfa, there is an increase in the quantity of saprophytic bacteria, actinomycetes and fungi of the genera Trichoderma and Penicillium which, together with mycolytic bacteria developing the alfalfa rhizosphere, facilitate a suppression of cotton wilt infection. The reduction in incidence of Verticillium-induced cottn wilt after alfalfa may be explained by the action of a variety of causes: a decrease in reserve of infection in the soil, a decrease in pathogenicity of the agent, the negative effect on it of alfalfa root phytoncides, nodule and mycolytic bacteria, an increase in the number of antagonists in the microflora composition of the soil and an increase in the resistance of plants to the disease.
