Description

Application method of pesticides and pesticide preparations used in it {METHOD OF APPLICATION OF AGRICULTURAL CHEMICALS AND AGRICULTURAL CHEMICAL PREPARATION USED THEREFOR}

The present invention broadly relates to a method of application and to a method of application of agrochemicals in the formulation of pesticide preparations, in particular granules wetting agents, and to granulation wetting agents used therein.

Background Art Conventionally, a method of simultaneously applying a mixture of fertilizers and pesticides is known as one of the labor savings in pesticide application. For example, a method of seeding and applying pesticide-containing granular fertilizer at the same time ① (Japanese Patent Publication No. Hei 1-157492, Hei 8-245314, Hei 10-338604, Hei 10-338589) There is a method of applying granular fertilizer and pesticide additive separately ② and a method of mixing pesticide with liquid fertilizer (also called liquid fertilizer and paste fertilizer).

As for the method ①, there are a large number of combinations of fertilizers and pesticides, and it is impossible to sell all of them, and the agricultural worker cannot select any combinations as necessary. In addition, depending on the type of fertilizer, the pesticide-containing granular fertilizer is applied to the water of the rice paddy field, causing the pesticide component to be easily lost and its efficacy is insufficient.

As for method ②, granular fertilizer and pesticide can be combined arbitrarily, but fertilizer with attached device for applying fertilizer and pesticide separately is required. In addition, even when the fertilizer granules are discharged, even when such a device is attached, there is a problem in that the discharge port and the granules are wetted by the return water of the rice paddy, and the granules are blocked at the discharge port.

The method ③ is very convenient in that liquid fertilizers and pesticides can be arbitrarily combined, and can be operated in the same manner as fertilizing only ordinary liquid fertilizers. In addition, since liquid fertilizer mixed with pesticides is applied in the soil, there is little loss of pesticide components.

However, also in the method ③, when the pesticides are mixed, depending on the formulation of the pesticides, it is necessary to dilute the preparation once in water, and then to mix the liquid fertilizer. Particularly, since granules do not disintegrate even when directly injected into liquid fertilizers, granules hydrous agents are first diluted with water to prepare a thick suspension, and it is necessary to mix them with liquid fertilizers. In addition, the method after dilution with water requires the preparation of a container for dilution, the preparation of water, and the low dilution ratio (same magnification dilution). . In addition, when applying a pesticide and a fungicide at the same time, it is necessary to dilute each pesticide in water separately, such as mixing and application of one pesticide disinfectant with liquid fertilizer can not be found.

The main object of the present invention is to solve the problem of mixing the granules with the liquid ratio and applying them to the liquid bath.

Another object of the present invention is to provide an efficient application method of the insecticide.
