Several StollerUSA products are now approved for organic production, including the fungicide Top Cop with Sulfur.
Top Cop with Sulfur oxidizes on the crop leaf and the copper is promptly soluble. The fast action of Top Cop means less copper is needed to control the pathogens, according to the company. Without the buildup of copper on the older leaves of the plant, the risk of phytotoxicity may be reduced.
Currently 12 Stoller products are among the line of organic approved crop solutions. For more information on the Stoller products approved for organic production, go to www.stollerusa.com/organicproducts.
