定性は、十分とは言えないのが現状である。In the conventional aqueous emulsion pesticide formulation, the particles become large due to fluctuations in the solubility of solid fine particles in water, surfactants, or organic solvents due to minute temperature changes, resulting in the formation of a suspended emulsion-dispersed phase. At present, the stability of the dispersion system cannot be said to be sufficient, as there is separation due to floating or sedimentation.

への安全性向上がはかられている。Pesticides originally began with the use of natural products, and then through the use of processed products and the era of inorganic compounds, and have now moved on to today's era of organic compounds, where their insecticidal, sterilizing, herbicidal, killing, and plant growth regulating effects have become powerful, and their economic value has increased. The effect was enormous. However, on the other hand, there are still cases where the unavoidable toxic effects of pesticides still occur, and less toxic substances derived from natural substances have been discovered, and through research on their formulation technology, synergistic control effects and reduction of chemical damage have been discovered. At the same time, efforts are being made to improve safety for users and consumers of agricultural products.

In other words, it not only reduces the inherent toxicity, acute, subacute, chronic, and teratogenic toxicity of the pesticide, but also reduces skin irritation, mucous membrane irritation, local allergy to humans and animals, which could not be achieved with conventional techniques, or the toxicity of sprayed liquids. It reduces secondary toxicity such as cough irritation during inhalation. In addition, we select low-toxicity and low-cost raw materials such as water to improve the safety, storage stability of the pesticide components, and light resistance of the sprayed pesticide components. It provides:

2 Δρ (where r: particle radius, Δρ: density difference between the dispersed phase and dispersion medium, η: viscosity of the dispersion medium, 1 g: gravitational acceleration). Therefore, in order to make this ν infinitesimally small, as mentioned above,
Although the dispersed phase particle radius is made minute and the viscosity is kept thick within a certain range, the present invention further maintains the weighted average density of the dispersed phase and the dispersion medium within a range of 90 to 110%, In addition, the viscosity is adjusted by adding a polymer thickener to stabilize the suspension and/or emulsification of the dispersed phase.Furthermore, the water diluted liquid has viscoelasticity or spinnability (spindlaby).

The viscosity should be at a level that makes it easy to pour, or a viscosity that can be thixomorphized into a sol by a gel. This improves the separation stability of the composition and improves the adhesion of the diluted spray solution to crops and the like by wet spreading.

狭く一定にすることができ、飛散が少なく、結果的には
薬液曝霧の危険を防止することができる。この現象は、
とくにポリ酸化エチレンの場合効果が著しい。In addition, the liquid exhibits viscoelasticity, that is, stringiness, and the spray angle can be kept narrow and constant, resulting in less scattering and, as a result, the danger of chemical liquid exposure can be prevented. This phenomenon is
The effect is particularly remarkable in the case of polyethylene oxide.
