| Abstract: | In controlling tomato gray mold (caused by Botrytis cinerea Pers.) in the field, pyrimethamil 40% SC at a 1:800 dilution provided 90.1 and 85.2% protection of leaves and fruits, respectively. These results were significantly better than the protection provided by procymidone 50% WP at a 1:1000 dilution. At dilutions of 800 to 1200, pyrimethamil provided 85 to 90% protection with good crop safety. |
