This pathogen is soil borne. Cowpea plants became diseased when grown in infective soil, or in sterilized soil watered with infective leaf or root sap, or in soil to which infected roots were added. Treatment with pcntachloronitrobenzene destroyed infectivity. Air-drying for more than a week or fine grinding do not destroy infectivity. The pathogen perhaps is released through roots of infected plants. Soil water plays a major part in spread of the disease in nature.enroot(wilt) diseaseroot(wilt) pathogensoil transmission-diseaseArticle
