Patent ID: 8221796

Claim:
A fungicide/bactericide composition comprising: (a) a complex of copper and a carboxylic acid derivative, in which the ratio of copper and carboxylic acid derivative is between 1:0.07 and 1:0.19 based on the weight of copper compound and carboxylic acid derivative; (c) a first dispersant, wherein said first dispersant is selected from the group consisting of a block copolymer non-ionic surfactant having an average molecular weight of between 1,000 and 15,000, a polyacrylic acid derivative having a pH of between 5 and 10 and an average molecular weight of between 1,000 and 37,000, and combinations thereof; and (e) a second dispersant, wherein said second dispersant is selected from the group consisting of lignin sulfonate, naphthalene sulfonate and combinations thereof, and wherein the weight of said copper compound is between 5% and 39% of the total weight of said composition.
