Benomyl or thiophanate-methyl applied as dips to strawberry nursery plants before planting provided significantly better control of Ramularia leafspot than all other materials tested. Benomyl in southern California and thiophanate-methyl or benomyl in northern California gave the best leafspot control when fungicides were applied as sprays after planting. Selecting leafspot-free plants or obtaining plants from nurseries following a benomyl spray program prevented leafspot developing in fields in southern California. Most fungicides tested were either phytotoxic or gave ineffective control of leafspot.
