摘要:
The invention is concerned with micro granules for pesticides and their manufacture by wet grinding a suspension of the active compound together with adjuvants in a ball mill to a particle size of at most 0.01 mm and subsequent spray-drying of the suspension thus obtained under a pressure of from 5 to 8 atmospheres gauge and at 140.degree. to 300.degree. C.
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.

Ultra low volume formulations of endosulfan (6,7,8,9,10,10-hexachloro-1,5,5a,6,9,9a-hexahydro-6,9-methano-2,4,3-benzodioxathiepine-3-oxide), comprising endosulfan, a mixture of a vegetable oil and aromatic hydrocarbons, and an epoxide stabilizer.
摘要:
Dispersions of 2-methyl-5,6-dihydropyran-3-carboxylic acid anilide in paraffinic mineral oils, liquid triglycerides and/or liquid esters of C.sub.1 to C.sub.12 monoalcohols have an improved effect against rust diseases and an extended spectrum of effectiveness against diseases caused by Colletotrichum types. The dispersions can be stabilized against crystal growth by adding aluminum chelates of certain hydroxy quinones, e.g. allzarin.
