Chemical control of strawberry anthracnose caused by Colletotrichum acutatum

Abstract

Two soil disinfectants, chloropicrin and dazomet, were effective for control of strawberry anthracnose caused by Colletotrichum acutatum in nursery beds. Five fungicides, propineb, pefurazoate, dithianon, mancozeb and thiram, were effective for control of irregular leaf spot and black petiole spot of this disease during the period of seedling growth also. Especially, propineb, pefurazoate and dithianon were remarkably effective. Benomyl and copper-oxinate gave some control of this disease. However, bitertanol, triflumizole, pyrifenox, SSF-129SC10 and a mixture of diethofencarb and thiophanate-methyl showed a little activity against this disease.
