摘要：
A method of producing a controlled release form of an agricultural active material includes the provision of an organic liquid composition in which the active is present, but where the liquid composition 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 microcapsules, the shell of which is designed to release the agricultural active at a pre-selected controlled rate when the microcapsule is exposed to natural environmental conditions. Controlled release forms of agricultural actives are also provided.
