Description

The present invention relates to an agrochemical emulsifying composition.

Agrochemical emulsifiable compositions are homogeneous liquid compositions in which an agricultural chemical active ingredient, a surfactant (emulsifier) and a solvent are mixed. The agricultural chemical emulsifying composition is diluted with water when used, and spontaneously forms an emulsion (a state in which fine oil droplets are dispersed in water). At this time, the solvent in the emulsion may gradually dissolve in water, and as a result, the dissolving power of the agricultural chemical active ingredient in the emulsion may decrease, and crystals of the agricultural chemical active ingredient may precipitate in water. Precipitation of crystals is detrimental to the user, such as a decrease in biological activity and clogging of the filter of the sprayer. The present inventors have reported an agrochemical emulsifying composition that exhibits good emulsification stability even after being diluted with water (Patent Document 1).

WO2014/119519

The present invention has been made in view of the above problems, and an object of the present invention is to provide an agrochemical emulsifying composition having greatly improved emulsion stability when diluted with water.

The present inventors have made intensive studies to solve the above problems, and found that the use of 3-methoxy-N,N-dimethylpropanamide as a polar solvent greatly improves the emulsion stability when diluted with water. The present inventors have completed the present invention by finding that an emulsifiable agricultural chemical composition obtained by the above method can be obtained.

That is, the present invention provides the following agricultural chemical emulsifying composition.
1. (a) at least one pesticidally active substance selected from fluxametamide, pyridaben, amisulbrom and quizalofop-p-ethyl;
(b) (b-1) a polar solvent containing 3-methoxy-N,N-dimethylpropanamide, and (b-2) a mixed solvent containing a non-polar solvent, and (c) an agricultural chemical emulsifying agent containing a surfactant Composition.
2. (b-2) The agrochemical emulsifying composition of 1, wherein the non-polar solvent is an aromatic hydrocarbon.
3. (b-1) Agrochemical emulsifying composition of 1 or 2, wherein the mixing ratio of (b-1) polar solvent and (b-2) nonpolar solvent is polar solvent:nonpolar solvent=15:85 to 65:35 by mass. .
4. (c) The agricultural chemical emulsifying composition according to any one of 1 to 3, wherein the surfactant comprises a nonionic surfactant.
5. The nonionic surfactant contains at least one selected from the group consisting of polyoxyalkylene arylphenyl ethers, formalin condensates of polyoxyalkylene aryl phenyl ethers, polyoxyalkylene vegetable oils and polyoxyethylene polyoxypropylene block polymers. 4 pesticide emulsifying composition.
6. (c) The pesticidal emulsifying composition of 4 or 5, wherein the surfactant further comprises an anionic surfactant.

Since the emulsifying composition of the present invention has greatly improved emulsion stability when diluted with water, it is excellent in handleability and has high biological activity.

Table 1 shows the results. The term "extremely small amount" means that a slight amount of sediment can be observed at the bottom of the graduated cylinder, although the amount of sediment is not large enough to be read on the scale of the graduated cylinder.

After standing, the diluted solution was filtered through a membrane filter (pore size 1.0 μm). The filter and filter residue were allowed to stand in a dryer set at 60° C. for 2 hours to dry. Based on the mass A (mg) of the residue on the filter after drying and the mass B (mg) of the active agricultural chemical contained in 1 mL of the emulsified agricultural chemical composition, the crystal deposition rate was calculated from the following formula.
Crystal deposition rate (%) = A/B x 100

From the above results, the pesticidal emulsifying composition of the present invention has a small amount of sediment and a small crystal precipitation rate even after being diluted with either 3 degree hard water or 19.2 degree hard water, so the emulsification stability is large. found to be improved.
