Five organic materials, Calopogonium sp., rice straw, wood sawdust, fresh guinea grass and poultry manure, were added to soil in a field with a recent history of high stalk rot in maize caused by Macrophomina phaseolina and Fusarium moniliforme. The two stalk rot organisms reacted differently to the organic amendments. All the amendments significantly reduced the incidence of Fusarium stalk rot disease. Amendment of soil with fresh Calopogonium leaves had almost no effect in controlling the incidence of Macrophomina phaseolina. Organic amendment with poultry manure stimulated the disease. The other amendments appeared to be equally effective in checking the disease. Suppression of the disease appeared to be related in increased microbial activities.
