Fusarium Wilts

Many studies have demonstrated the capacity of non-pathogenic strains of F. oxysporum to control Fusarium diseases.<br />These non-pathogenic strains show several modes of action contributing to their biocontrol capacity. They are able to<br />compete for nutrients in the soil, affecting the rate of chlamydospore germination and the saprophytic growth of the<br />pathogen, diminishing the probability for the pathogen to reach the root surface. They are competing with the pathogen<br />at the root surface for colonization of infection sites, and inside the root where they induce plant defence reactions. By<br />triggering the defence reactions, they induce systemic resistance of the plant. Depending on the strain, and on the plant<br />species, these mechanisms are more or less important, leading to a more or less efficient biocontrol efficacy.

Chlamydospore Germination

Amending soil with alfalfa hay or other dried, green plant residues stimulated chlamydospore germination of Thielaviopsis basicola. Within 3 to 6 days the germ tubes lysed resulting in the decline in viable chlamydospores and of disease severity of soybean seedlings planted in amended soil. When chlamydospores were added immediately after the amendment, maximum germination was recorded after 2 days. The number of spores with germ tubes declined to zero after 6 days as a result of lysis. Incubation of alfalfa in soil for 1 or more days before chlamydospores were added reduced or nullified the effect of the amendment. Water-soluble substances from alfalfa hay, including carbohydrates, amino acids, and organic acids, were more stimulatory and caused greater decline in chlamydospore population than ether or chloroform-methanol-soluble substances.
