Assessment of Chemical and Biological Agents Against Important Forest Pathogens

Abstract

Pathogens are known to cause losses to forest yield. Fungicidal application has been found to be effective against many pathogens but biological control holds promise as a strategy for disease management and it is environment friendly too. So, three pathogen having vast host range of forest plants viz., Pestalotiopsis sp., Cerotocystis sp., Armillaria sp. were selected for study. Approach includes in vitro efficacy of systemic and non-systemic chemical fungicides against selected pathogens along with Trichoderma species (Trichoderma viride, T. harzianum, T. koningii) as bio-control agent. Devithiram was found to be promising fungicide and T. koningii was best suitable as biocontrol.
