Seed Treatment Awarded Special Local Needs Label

United Phosphorus Inc. has received a special local needs (SLN) label for Topsin M 70WP (thiophanate-methyl) in the state of Washington. The label allows for use as a seed treatment for spinach grown for seed. The SLN was approved for use as a seed treatment for control of seedborne Verticilium dahliae on spinach seed that is planted solely for seed production.

The use of Verticillium free seed is only one factor in managing Verticillium in the crop and on the seed produced. Soilborne Verticillium, environmental conditions and other factors also contribute to the occurrence of Verticillium wilt and Verticillium infested seed. Use Topsin M 70WP seed treatment in conjunction with an effective soilborne Verticillium management program (e.g. crop rotation and soil fumigation) for best results.
