Six fungicides (Aatopam‐N, Aldrex T, Calixin M, PCNB, captan and captafol) were evaluated at 200 mg a.i.l −1 for their effectiveness in reducing basal stem rot disease incited by Sclerotium rolfsii on tomato in pre‐ and post‐inoculation soil drenches in the glasshouse. The results showed that only PCNB effectively reduced disease severity when applied to soil 10 days before inoculation. Of the two application methods only pre‐inoculation soil drenching with the fungicides was efficacious in reducing disease severity. In field trials conducted in Samaru with Aldrex T, captan and PCNB, only PCNB was effective in combating the severity of the disease. It reduced the disease by about 88% in one trial.
