CROP PROTECTION COMPOSITION COMPRISING A CROP PROTECTION SOLID PARTICLE COATED WITH A WATER-INSOLUBLE COATING MATERIAL AND A CROP PROTECTION MIXTURE COMPRISING THE SAME

摘要

A composition comprising a mononucleate solid crop protection particle coated with a water-insoluble coating material has a diameter in the range of 0.5 to 50 ν. This composition is made by a process which results in substantial non-agglomeration of the coated particles. In a particular embodiment, a crop protection composition comprises a mononucleate solid crop protection particle coated with either wood rosin, rosin derivatives, waxes, fatty derivatives, sterols, long-chain sterol esters and sulfur. Alternatively, the coating material may be a water-insoluble synthetic latex polymer. The composition may be used in a mixture which also includes a crop protection chemical partner comprising a solid particle. The partner ordinarily degrades the solid crop protection particle when stored or aged together as a solid particle mixture. However, when the composition solid particle is coated, this degradation is prevented.
