Role of soil amendment and repeated cropping in the management of pea root rot

摘要

Soil amendment and repeated cropping with different non-host crops such as wheat, oats, maize and sorghum reduced the population of Fusarium oxysporum f. sp. pisi and F. solani f. sp. pisi in the soil and the severity of pea root rot due to these pathogens. F. solani f. sp. pisi was more sensitive to soil amendment, and wheat and especially maize were more effective than the other two non-host crops. Repeated cropping of non-host species was more effective than a single crop. No relation was established between the population of the Fusaria and severity of pea root rot.
