摘要:
The invention relates to plant-protection agents which contain one or more active ingredients and which are based on suspoemulsions containing aqueous and organic phases, where the organic phase contains one or more surfactants from the group comprising the ethylene oxide/propylene oxide block polymers having an average molecular weight of 1,000-20,000. The suspoemulsions are subjected to large shear forces. Even thereafter, they exhibit a constant viscosity behavior, in spite of a large number of droplets and a low droplet size.
摘要:
Aqueous emulsions of a plant protective agent such as a pesticide dispersed in the presence of a phosphate ester of a block copolymer of (1) ethylene and propylene oxides or (2) of an ethoxylated/propoxylated fatty alochol.
摘要:
The present application describes herbicidal agents, based on emulsions, which contain two or more active compounds - a water-soluble, salt-like active compound and an active compound which is soluble in organic solvents - a surfactant mixture and a solvent, the surfactant mixture comprising a combination of phenylsulfonate salts, ethoxylated alkyl- (or polyaryl)phenol phosphates, ethoxylated acidic phohsphoric acid esters and alkylphenol polyglycol ether derivatives. These agents are prepared by the action of high shear forces.
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.
摘要:
Subject of the invention are liquid pesticidal compositions in the form of aqueous suspension concentrates, which in addition to the active substance or mixture of active substances contain an alkali metal salt of sulfosuccinic acid semiester prepared by reaction of a polyglycol ether of a condensation product of (C.sub.8 -C.sub.12)-alkylphenol and formaldehyde with maleic anhydride and an alkali metal sulfite, in combination with a mixture of an alkali metal salt of a ligninsulfonic acid and identical parts of a swelling alkaline earth metal silicate. These suspension concentrates have an advantageous stability to storage.
