Abstract
Both novel and known S-(substituted-phenyl) N-alkylthiolcarbamates such as 4-fluorophenyl N-methylthiolcarbamate, and S-(substituted-phenyl) N,N-dialkylthiolcarbamates such as 2-chlorophenyl N,N-dimethylthiolcarbamate are disclosed. These are useful to control plant pests such as Phytophthorans infestans (Late Blight of Tomatoes) and Pythium ultimum (Damping Off). Also disclosed are the methods of controlling this plant pest with these compounds.
