This 16-ounce liquid concentrate has a low concentration of copper soap (10%) and can be used right up to the day of harvest to tackle many common and uncommon plant diseases and can even be effective on late-stage blight. The product mixes instantly with water so you can use it immediately with a hose-end/tank sprayer.
Drying Copper Concentrates
The benefits gained by drying copper concentrates prior to the smelter include: ¹. By drying copper concentrates, producers can ultimately reduce costs associated with fuel and exhaust gas handling, as well as have a more concentrated stream of SO 2, which is then less costly to convert to sulfuric acid.
