    摘要： The invention relates to a process for the preparation of dispersions of plant protection agents, wherein at least one active ingredient being metered, in the molten form, into the outlet stream of a jet, which stream contains a solution of the formulation aids. The process is suitable for all active ingredients which form a stable melt and have a melting point above 70.degree. C. The resulting dispersions have advantageous stabilities.
