摘要

A study was carried out to determine the role of rhizosphere-residing bacteria in the observed pendimethalin- and prometryn-mediated increase in cotton seedling damping-off incidence caused by Rhizoctonia solani. Judging from the results, pendimethalin-mediated increase in disease incidence may be due to a decrease in the populations of indigenous cotton root colonizing bacteria in the presence of pendimethalin. Prometryn-mediated increase in disease may be due to a decrease in the populations of indigenous root colonizing bacteria as well as increased susceptibility of cotton seedlings to R. solani infection in the presence of prometryn. Pendimethalin and prometryn neither affected the growth of R. solani nor caused any visible change in seedling physical characteristics.
