All the fungicides tested showed varying degrees of phytotoxicity. Blasticidin-S, du-ter W-50 and PMA gave significant control. In general, 2 spray applications were better than one. Mild outbreaks of tolast were related to fewer conidia in the atmosphere and no striking build-up of conidia developed during the susceptible stages of plant growth.
