Abstract
Drying and remoistening of the soil had no effect on V. dahliae Kleb. propagule numbers or on the infection of cotton and Datura stramonium by the pathogen. N and P as fertilizer amendments were equally ineffective in reducing disease incidence; in air-dried soil, propagule numbers were reduced after amendment with N and P. Acidification of the soil with aluminium sulfate reduced infection of both cotton and D. stramonium and propagule numbers were also drastically reduced.
