Description
The propagules of Rhizoctonia solani, the causal agent of web-blight disease of Macroptilium atropurpureum cv. Siratro, were present in field soils providing the inoculum for further infection. The pathogen intensified its activities within the infected areas where most propagules were detected, with the uses of soil immersion tube and a selective isolation medium, to remain in the soil layer of 0-5 cm depth. The soil inoculum could possibly be disseminated by rain water into healthy plant areas. Fungicide treatments as soil drenches onto infested soils collected from infected fields significantly reduced the amount of infective propagules of R. solani as determined by the percentage of infected Siratro seedlings. Carboxin and Pentachloronitrobenzene were the most effective among the tested chemicals.
