Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foamable agrochemical composition.

0002

BACKGROUND OF THE INVENTION Foaming agricultural chemical compositions have been known as described in Japanese Patent Publication No. 45-24360, Japanese Patent Publication No. 47-27930, Japanese Patent Publication No. 50-20128, and the like.

0003

[Problems to be Solved by the Invention] However, the above-mentioned foamable agricultural chemical compositions have had problems such as poor stability during storage. In other words, because conventional effervescent preparations contain carbonate and solid acid, they cannot be used in kraft bags, polyethylene bags,
When stored in polyethylene bottles, etc., moisture in the air is absorbed and carbon dioxide gas is generated, causing a problem of reduction in product weight. Furthermore, when stored for a long period of time, the foamability decreases, resulting in a decrease in disintegration in water, dispersibility in water, diffusivity, etc. Furthermore, if stored in an aluminum bag with a polyethylene interior that is not gas permeable, the bag may expand due to the reaction with moisture present in the formulation, producing carbon dioxide gas, and there is a risk of the bag being damaged in severe cases. There is also gender.

0004

[Means for Solving the Problems] In view of the above circumstances, the present inventors have made extensive studies and found that agrochemical active ingredients, surfactants, carbonates, which are pest control active ingredients or plant growth regulating active ingredients, solid acids and calcium oxide and/or
Alternatively, the present inventors discovered a foaming agricultural chemical composition containing barium oxide and having excellent storage stability, leading to the present invention.

That is, the present invention contains a) a pesticide active ingredient, b) a surfactant, c) a carbonate, d) a solid acid, and e) calcium oxide and/or barium oxide, and a combination of the carbonate and the solid acid. At least one of them is water-soluble, and the total content of carbonate and solid acid is 5 to 50% based on the total weight.
90%, and the weight ratio of carbonate and solid acid is 1:10 ~
10:1 and calcium oxide and/or
Or the weight of barium oxide is 0.5 to 4 relative to the total weight
0%, preferably 1 to 15% of an effervescent agricultural chemical composition (
Hereinafter, it will be referred to as the composition of the present invention. ).

[0006] In the composition of the present invention, the pesticidal active ingredient used as a pest control active ingredient or a plant growth regulating active ingredient is not particularly limited, but includes, for example, the following compounds and their active isomers or mixtures thereof. can be mentioned.

In the composition of the present invention, when the melting point of the active ingredient is less than 70°C, it is preferable to add a calcined product of wet process silica or dry process silica. In addition to the essential active ingredients, surfactants, carbonates, solid acids, and calcium oxide and/or barium oxide, water-soluble carriers, water-soluble polymers, mineral carriers, solvents, lubricants, and disintegrating Agents, etc. can be mixed as necessary.

[0050] In the composition of the present invention, each of the agriculturally active ingredients can be used singly or in combination of two or more, and when used in combination, the mixing ratio can be arbitrarily selected. The content of these active ingredients varies depending on the type of the ingredients, but is generally 0.01 to 80% by weight, preferably 0.1 to 50% by weight, based on the total weight of the composition of the present invention. In addition, when these active ingredients are used as a liquid or dissolved in a solvent, if the content of the liquid component including the solvent exceeds 60% by weight based on the total weight of the composition of the present invention, it is considered an oil absorbent. Since the effect of certain fired products of wet process silica or dry process silica is insufficient, the content of this liquid component is usually 0.01 to 60% by weight, preferably 0.1%.
~40% by weight.

[0051] When the calcined product of wet process silica or the dry process silica is used as a liquid active ingredient or dissolved in a solvent, the amount added is usually 50 to 20% based on the total liquid content.
0% by weight, preferably 60-100% by weight. Examples of baked products of wet process silica include Tokusil (manufactured by Tokuyama Soda Co., Ltd.), Carplex #80 (manufactured by Shionogi & Co., Ltd.), Carplex #67, and Carplex #1.

Those fired at 900°C are used. Moreover, commercially available Carplex CS-5, Carplex CS-7, etc. may be used as they are. On the other hand, as dry process silica, light anhydrous silicic acid obtained by dry process, such as AEROSIL2
00, AEROSIL300 (manufactured by Degussa) is used.

Furthermore, when the melting point of the active ingredient is 0 to 70°C, a solvent may be added as necessary to lower the viscosity during production and to prevent crystallization of the active ingredient when stored at low temperatures. As the solvent, a nonvolatile or low volatility organic solvent is usually used. Solvents used for the purpose of controlling the viscosity and preventing crystallization of the active ingredient include those that mix uniformly with the active ingredient, such as aromatic hydrocarbons such as phenylxylylethane, ketones, esters,

The period is up to the date.

When applying the composition of the present invention as it is,
Usually does not require any special equipment. For example, an applicator may enter a paddy field and apply the composition of the present invention uniformly or at one or more locations in the paddy field, or may apply the composition to the side of a ridge or water outlet of the paddy field without entering the paddy field, or may apply it from the ridge. This allows the active ingredients to be distributed throughout the rice field. It is also possible to spray from the ridges with a power spreader (spreader), or from the air using a helicopter, airplane, radio-controlled airplane, etc.

Moreover, since it is uniformly diffused, it is an excellent composition in terms of reducing chemical damage to crops. In addition, when the composition of the present invention is applied to paddy fields, the application amount can be significantly reduced compared to the conventional application amount (for example, 3000 to 4000 g per 10 ares in the case of granules). transportation,
It is highly useful in terms of storage and labor-saving spraying. Furthermore, when the composition of the present invention is used after being diluted with water, it is convenient to handle because carbon dioxide gas is generated in the water and disintegration, dispersion, emulsification, etc. are easy.
