Abstract

Metalaxyl, used in granules pre‐sowing, in drenches at seedling emergence, or in routine spray applications during plant growth, gave good control of downy mildew in brassica seedbeds (caused by Peronospora parasitica (Pers. ex Fr.) Fr. and of downy mildew in lettuce crops (caused by Bremia lactucae Regel). Phosetyl was considerably less effective.
