Abstract

There is provided a liquid agrochemical composition having a stable water-diluted state, which comprises 0.5 to 30% by weight of one or more hydrophobic agrochemical active compounds, 1 to 20% by weight of one or more nonionic surfactants selected from the group consisting of a polyoxyethylene polyoxypropylene block copolymer and the like, 0 to 10% by weight of one or more anionic surfactants, 6 to 60% by weight of an ether compound represented by R<1>-O-A<1>-O-A<2>-(O-A<3>)n-O-R<2>, wherein R<1 >and R<2 >represent a C1-3 alkyl group, A<1>, A<2 >and A<3 >represent an ethylene group or a propylene group, and n represents 0, 1 or 2, and 20 to 75% by weight of 1,3-dimethyl-2-imidazolidinone.

Description

technical field [0001] The present invention relates to liquid agrochemical compositions containing hydrophobic agrochemically active compounds. Background technique [0002] Typical examples of liquid agrochemical formulations containing hydrophobic agrochemically active compounds include emulsions and flowables. When emulsions and suspensions are sprayed, they are used as water-diluted solutions by diluting with a large amount of water. In the water-diluted solution, the hydrophobic agrochemical active compound is dispersed in water in the form of fine droplets or solid particles under the action of the surfactant. Since this state is a thermodynamically unstable state, the liquid containing the hydrophobic agrochemical active compound The droplets separate over time, and when the hydrophobic agrochemically active compound is a solid, the solid particles will in some cases settle and settle. [0003] The liquid agricultural chemical formulation described in JP2003-128501...
