きており、それに関する多くの研究かなされている。Recently, there has been an increase in the use of cloudy a drug formulations (flowable agents), in which a high-strength 73 mulberry one active ingredient is suspended and dispersed in water. Much research has been done.

キンクか生しると容器を軽く振ったたけては、再分散さ
せることは難しく、農薬製剤として使用できなくなる。The basic method for obtaining a water-suspended agricultural plant is to pulverize the active ingredients of agricultural chemicals, which are sparingly water-soluble and solid at room temperature, and disperse them in water using an interfacial agent. However, the water-suspended J:S drug that is dispersed with surfactant +'t agents causes aggregation and separation of the pesticide's active ingredients during scooping, sometimes resulting in heart caking. There is. If the container is shaken lightly, it will be difficult to re-disperse it and it will no longer be usable as an agrochemical preparation.

また改Hか不十分なのか現状てある。In order to solve these problems, research is being carried out on ways to stabilize the viscosity of the dispersion system by adding various viscosity modifiers to the aqueous suspension. For example, non-ionic? l: A method using a superactive agent and a water-soluble polymer such as heteroborosatucharite (Japanese Patent Publication No. 53-46889), a method using a superactive agent mixed with xanthan gum (Japanese Patent Publication No. 57-5860 1) (Japanese Unexamined Patent Publication No. 63-830 No. 1, $4!). Method using surfactant cutting and hydrated aluminum silicate powder (JP-A-51-
Publication No. 79729). However, in general, increasing the viscosity impairs the ability of the suspension to be discharged from the container during use, and lowering the viscosity causes problems such as coagulation and sedimentation due to the effectiveness of the pesticide. Then again, the current situation is whether the reform is insufficient or not.

The present invention was perfected by discovering that it would maintain the same characteristics. The water-insoluble solid agricultural chemical active ingredient 7 used in the wood-based plant is not particularly limited, and can be used as long as it has a solubility in water of about 1% rat% or less at room temperature. For example, the following can be mentioned.
