Biological control of basal stem rot of tomato (Lycopersicon esculentum L.) caused by Sclerotium rolfsii in the field condition was conducted by using Chaetomium cupreum as a potential microantagonist. The experiment was done by using Randomized Complete Block Design with five replications. Using viable ascospores, crude extract of microantagonist and heat killed ascorspores of C. cupreum the disease percentage could be reduced significantly and was different when compared to the nontreated check. However, using PCNB as chemical control was more effective to control the disease than using microantagonist. The microantagonist treated one had plant growth parameters and yields as similar as chemical treated one.
