Abstract
An alternative to the use of chemical fungicides that has gained much recognition and interest in recent years is biological control. This paper takes a look at biocontrol mainly from a chemistry perspective and highlights the potential of developing natural products from biocontrol agents as new antifungal compounds. Species of the genus Trichoderma arc common fungi found in almost any soil. Some members of this genus are antagonistic to other fungi including plant pathogenic species. These have been developed as biocontrol agents particularly for control of mildew diseases caused by Rhizocionia. &dawn. Fusarium. Botrytis and Sclerotinia. l3iocontrol agents are potentially good sources of bioactive compounds. There have already been some previous reports of compounds with antifungal activity isolated from Trichoderma biocontrol agents. In a preliminary study, the acetone extract from a culture of Trichoderma harzianum grown in coconut water was found to have activity against Rhizoctonia solani. A clear zone of 15 mm was observed for the crude extract using the paper disc diffusion assay
