Abstract

PURPOSE:To obtain an agrochemical granular agent as a formulation high in utility, because the lowering in the hardness of the granules can considerably be reduced in comparison with conventional formulations and the powdering of the formulation can be prevented, even when stored under a high humidity condition. CONSTITUTION:This agrochemical granular agent comprises (a) an agrochemically active agent, (b) sodium montomorillonite, (c) sodium carboxymethylcellulose, and (d) one or more of surfactants consisting of the group of an alkylbenzene sulfonate salt, a sulfosuccinic acid diester surfactant and a polycarboxylic acid surfactant.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to pesticide granules that show little reduction in particle hardness during storage under high humidity conditions.

[0002]

2. Description of the Related Art Usually, pesticides are used in order to spread the active ingredient easily and efficiently and maximize their effects.
It is used after being formulated into various dosage forms. Among them, granules have the characteristics that they can be sprinkled or mechanically sprayed, and that they are less prone to dusting and drift than powders and are safe for the user. Extrusion granulation method, impregnation method, coating method, etc. are known as methods for producing granules, but since continuous production is possible, a large amount of preparations can be produced, and further there is no powdering during production and workability is improved. Because of its superiority, extrusion granulation has become the mainstream for granule production.

[0003]

However, the granules produced by the conventional extrusion granulation method have a low particle hardness when stored under high humidity conditions such as in the summer, and are easily chipped when impacted. As a result, there is a problem that powdering easily occurs. In particular, when the hygroscopicity of the pesticide active ingredient is high or the water solubility thereof is relatively high, the decrease in particle hardness is remarkable, which is a problem.

[0004]

Means for Solving the Problems The inventors of the present invention have made earnest studies in view of such a situation, and as a result, an agricultural chemical granule containing sodium montmorillonite, sodium carboxymethyl cellulose and a certain surfactant has the above-mentioned problems. The inventors have found that the above can be improved and have reached the present invention.
That is, the present invention comprises a group of a) agrochemical active ingredient, b) sodium montmorillonite, c) sodium carboxymethyl cellulose, and d) alkylbenzene sulfonate, sulfosuccinic acid diester type surfactant and polycarboxylic acid type surfactant. The present invention relates to a pesticide granule containing one or more surfactants (hereinafter, referred to as the composition of the present invention).

The pesticidal active ingredient used in the present invention is not particularly limited, and examples thereof include pyrethroid-based, organic phosphorus-based, carbamate-based insecticides, fungicides, herbicides, plant growth regulators, and the like. Such compounds and active isomers thereof or mixtures thereof are mentioned.
