1. A coated seed comprising
A) a seed, and
B) a coating composition coated on the seed comprising a polar polyolefin dispersion, which comprises:
i) a polar polyolefin; and
ii) 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 a base 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;
and wherein the neutralizing base is triethanolamine (TEA), and 20 to 90 mole percent of the carboxylic acid groups or the carboxylic acid anhydride groups are modified by the neutralizing base.
