Sap-stain fungi attack the wood immediately after felling or sawing and cause reduction in the value of timber by discolouring sapwood. Wood blocks of three tree species (Populus deltoides, Syzygium cumini and Mangifera indica) were artificially inoculated with three sap-stain fungi (Lasiodiplodia theobromae, Trichoderma harzianum and Ceratocystis sp). After 5 weeks of incubation 1.97 to 9.68 per cent weight loss was recorded in wood blocks inoculated with sap-stain fungi. Maximum weight loss was recorded in the wood block of P deltoides followed by S cumini and M indica. The in vitro evaluation of selected fungicides on sap-stain fungi revealed that carbendazim and benomyl were quite effective while copper oxychloride was least effective.
