Controlled release microcapsules

摘要: Microcapsules are prepared by encapsulating a core material with capsule shell wall containing glutaraldehyde crosslinked gelatin and at least one water soluble plasticizer that reduces the permeability of gelatin. Optionally, also contains feeding deterrent dissuades accidental ingestion microcapsule. Upon exposing microcapsules to water, is removed making permeable whereby encapsulated released. Materials such as insecticides, herbicides, plant growth regulating agents, fungicides may be released controlled location, time rate.
