Claim Text:
1. A herbicidal composition comprising an aqueous suspension of microcapsules, the microcapsules having a capsule wall of a porous condensate polymer, wherein the microcapsules contain a solution of fluroxypyr in a rosin solvent system comprising rosin and/or a rosin derivative; wherein the polymer is formed from polyurea, the polyurea is formed from polymethylene polyphenol isocyanate; the rosin and/or rosin derivative is methyl ester of hydrogenated rosin; the microcapsules have a particle size range of from 0.5 to 60 microns; the weight ratio of fluroxypyr to rosin solvent is from 1:10 to 10:1; wherein the fluroxypyr is present in an amount of 50% by weight of the microcapsules; the polymer is present in an of amount 3.5% by weight of the microcapsules; and the rosin and/or rosin derivative is present in an amount of 20% by weight of the microcapsules.
