Five fungicides were evaluated to control Botrytis blight of containerized western larch seedlings at the Champion Timberlands Nursery, Plains, MT. Fungicides were applied at biweekly intervals before and after seedling inoculation with Botrytis. Vinclozolin (Ornalin®) caused severe phytotoxicity to seedlings, resulting in enhanced mortality and premature needle loss. Captan and chlorothalonil (Bravo 500@)) stunted seedlings. Botrytis caused very little damage in this test. Control strategies should incorporate fungicide application with cultural operations that reduce seedling susceptibility and chances for infection.
