micro encapsulated aqueous suspension using the same general methods as described in u s pat no re38 675 and using the principles described therein and in u s pat no 5 583 090 to adjust the release rate such as increased particle size wall thickness and solvent content and in light of the equipment used to give a three pound per gallon concentrate but with the ratios of components adjusted to give a release rate of 4 6 plus or minus 0 4 as assayed by the same method the conditions of microencapsulation thus yield a ratio of release rates equal to 3 5 these two preparations of a clomazone micro encapsulated suspension are then blended together at a ratio of 30 of the first faster releasing preparation to 70 of the second slower releasing formulation to give the final blended formulation a three pound per gallon aqueous concentrate the preparations of clomazone microcapsules described in the above example i are blended together at a ratio of 40 of the first faster releasing preparation and 60 of the second slower releasing formulation to give final blended formulations of all three pound per gallon aqueous concentrates the two preparations of clomazone microcapsules described in the above example ii are blended together at a ratio of 40 of the first faster releasing preparation and 60 of the second slower releasing formulation to give final blended formulations of all three pound per gallon aqueous concentrates the two preparations of clomazone microcapsules described in the above example iii are blended together at a ratio of 40 of the first faster releasing preparation and 60 of the second.
