Abstract
A coated seed comprises a seed, and a coating composition coated on the seed comprising a polar polyolefin dispersion, which comprises: 1) a polar polyolefin; and 2) a neutralizing base; wherein the polar polyolefin is an olefin copolymer that contains one or more polar groups, wherein the polar groups are selected from the group consisting of a carboxylic acid group, a carboxylic acid anhydride group or a carboxylic acid salt moiety; wherein the neutralizing base is abase that modifies at least a portion of the carboxylic acid group, carboxylic acid anhydride group or carboxylic acid salt moiety of the polymer to form a stable aqueous dispersion with the polar polyolefin.
