MICROENCAPSULATING OF AN AGRICULTURAL ACTIVE HAVING A HIGH MELTING POINT

摘要

A method of producing a controlled release form of an agricultural active material includes the provision of an organic liquid compostion is free from aromatic solvents and is maintained below the normal melting point of the active. The liquid composition is formed into small droplets and the droplets are enclosed by a non-water soluble shell to provide microacapsules, the shell of which is designed to release the agricultural lactive at a pre-selected controlled rate when the microcapsule is exposed to natural envirnomental conditions. Controlled release forms of agricultural actives are also provided.
