Control of botrytis on strawberries

Abstract In laboratory tests thiram, dichlofluanid, and captan were most efficient in inhibiting conidial germination of Botrytis cinerea Pers., but benomyl and dichlozoline were better at inhibiting mycelial growth. Highest yields and the lowest amount of botrytis infection in a field trial were obtained from dichlozoline‐sprayed plants, benomyl and dichlofluanid being slightly less effective. The data suggest that use of a mixture of two fungicides one acting primarily against spore germination and the other against mycelial growth, may be the most effective way of reducing botrytis infection.
