Disease Cycle<br />

Species of Pythium naturally inhabit the soil.<br />

Infection in plant tissue is influenced by soil moisture,<br />

soil temperature, pH, cation composition, light and<br />

the presence of other organisms.<br />

Conditions for Development<br />

Optimum conditions for infection include wet soils<br />

during seeding through the first two weeks after<br />

transplanting. Soil moisture near saturation stimulates<br />

mycelium vegetative growth. Plants are more<br />

susceptible under these conditions: too high or too<br />

low temperatures; excessive moisture; poor quality<br />

light or unbalanced nutrition.<br />
