COPPER HYDROXIDE DRY FLOWABLE BACTERICIDE/FUNGICIDE AND METHOD OF MAKING AND USING SAME |
摘要 |
There is disclosed a granular copper hydroxide dry flowable bactericide/fungicide having improved biological activity and a method for making and using same. A bactericide/fungicide is made by forming a homogeneous aqueous slurry containing between approximately 5% and 20% by weight (based on the total weight of all dry ingredients) of a first dispersant selected from the group consisting of partially neutralized polyacrylic acid having a pH of between approximately 5 and 10 and an average molecular weight of between approximately 1,000 and 10,000 and lignin sulfonate, between approximately 0% and 5% by weight (based on the total weight of all dry ingredients) of a second dispersant for bentonite clay, between approximately 40% and 80% by weight (based on the total weight of all dry ingredients) phosphate stabilized cupric hydroxide and between approximately 6% and 30% by weight (based on the total weight of all dry ingredients) bentonite clay; and spray drying the slurry to thereby form a dry free flowing granular bactericide/fungicide product. The slurry can also include antifoam and wetting agents. Other partially neutralized polycarboxylic acid polymers useful as the first dispersant are also disclosed.
