Abstract

Survival ofXanthomonas campestris pv. manihotis (Xcm), the pathogen of cassava bacterial blight (CBB) disease, was investigated under field condition at Si Racha Research Station, Chon Buri province during rainy months from August to October, 1991. Field soil characters were sandy soil, low organic matter (0.5%) and pH 6.1-6.4. Survival Populations of Xcm strain CSg in plant tissue and soil samples were evaluated by using SXM semiselective medium. The Xcm pathongen survived shortly between 7-14 days in rhizosphere soil of cassava weeds and extendedly between 21-49 days in infected cassava tissues buried in the soil. The results indicated that infected cassava debris may be more important source of inoculum than rhizosphere soil of weeds for dissemination of CBB.
