Abstract
A plurality of releasably loaded elastomeric microspheres comprising a plurality of elastomeric microspheres loaded with at least one releasable agriculturally active agent within the optical boundaries of the elastomeric microspheres and post-polymerization addition and in-situ polymerization processes for preparing the releasably loaded elastomeric microspheres are also provided.
Claims8
A plurality of releasably loaded elastomeric microspheres wherein each releasably loaded elastomeric microsphere comprises an elastomeric microsphere and at least one releasable agriculturally active agent within the optical boundaries of the elastomeric microsphere in an amount sufficient to diffuse out of the elastomeric microspheres, wherein the elastomeric microspheres have an average particle size in the range of 0.5 to 300 micrometers.
