Description

  The present invention relates to an agrochemical imparted with viscosity by adding a paste.

  Conventionally, agricultural chemicals have been given moderate viscosity in order to prevent precipitation of agricultural chemical components and improve adhesion, and pastes such as xanthan gum have been added to impart viscosity. (Patent Document 1).

  On the other hand, some agricultural chemicals use the undiluted solution as it is, but some agricultural chemicals are used by diluting tens to thousands of times with water. When diluting a pesticide to which viscosity is imparted and using it, it is necessary to maintain an appropriate viscosity, so it is necessary to adjust the stock solution to a high viscosity.

JP 11-349403 A

  However, pesticides adjusted to a high viscosity are very difficult to handle and cannot be uniformly diluted. On the other hand, if the viscosity of the stock solution is lowered in order to facilitate handling and dilute uniformly, there is a problem that the viscosity of the diluted solution is not appropriate, precipitation of agricultural chemical components occurs, and adhesion decreases.

  Therefore, an object of the present invention is to provide an agrochemical that is easy to handle, can be uniformly diluted, and can maintain an appropriate viscosity even when diluted in water.

  In order to achieve the above object, the present invention provides a fluid liquid by dissolving a glue and a viscosity expression inhibitor in water to suppress the viscosity expression of the glue, and a water-containing target product. By adding an additive solution for thickening that is adjusted so that its viscosity or gelation is expressed when added, it is easy to handle, can be diluted uniformly, and is appropriate even when diluted in water. It was found that a high viscosity can be maintained. That is, the present invention provides a fluid liquid by dissolving a paste and a viscosity expression inhibitor in water to suppress the viscosity expression of the paste, and when added to an object containing moisture, the viscosity or It is an agricultural chemical characterized by containing the thickening additive liquid adjusted so that gelation may be expressed.

  In addition, the present invention is composed of a first liquid and a second liquid that develop a viscosity when simultaneously added to a target containing water, and an agrochemical component is contained in at least one of the first liquid and the second liquid. It is a pesticide.

  In order to achieve the above object, the present invention can provide an agrochemical that is easy to handle, can be uniformly diluted, and can maintain an appropriate viscosity even when diluted in water.

  As the thickening additive solution added to the agricultural chemical according to the present invention, those described in JP-A Nos. 2000-41594 and 2004-208562 can be used. Specifically, it is as follows.

  As the viscosity expression inhibitor, a poor solvent for the paste can be used, and as the poor solvent for the paste, for example, ethyl alcohol, acetone, isopropyl alcohol, fats and oils, surfactants and the like can be used. By adding such a poor solvent to the paste, the viscosity of the paste can be suppressed, and when added to an object containing moisture, the viscosity or gelation is expressed.

  Moreover, a low-viscosity polysaccharide can be used as the viscosity expression inhibitor, and examples of the low-viscosity polysaccharide include gum arabic, pullulan, soybean polysaccharide, and arabinogalactan. By adding such a low-viscosity polysaccharide to the paste, the viscosity of the paste can be suppressed, and when added to an object containing moisture, the viscosity or gelation is expressed.

These low-viscosity polysaccharides are effective in high-concentration dissolved solutions, for example 3 to 50% in the case of gum arabic, more preferably 8 to 30%, and 2 in the case of pullulan. A concentration of ˜20%, more preferably a concentration of 5-10%, for soybean polysaccharides a concentration of 3-30%, more preferably a concentration of 7-25%, and for arabinogalactans, 3-50 % Concentration, more desirably 8-30%. When the concentration is less than these, viscosity is developed when the paste is added, the fluidity is deteriorated, and a low-viscosity state preferable as a thickening additive liquid cannot be maintained. Of course, if the concentration of the paste is lowered, a liquid that maintains fluidity can be obtained, but it is inferior in the function of adding viscosity to the object containing water to develop viscosity. On the other hand, if the concentration range is exceeded, the viscosity of the low-viscosity polysaccharide itself becomes high and the fluidity itself is low.

  Furthermore, as the viscosity expression inhibitor, ions reactive with the paste can be used, and as the ions reactive with the paste, for example, metal ions such as potassium, calcium, and magnesium can be used. . By adding such reactive ions to the paste, the viscosity of the paste can be suppressed, and when added to an object containing moisture, the viscosity or gelation is expressed. When the addition amount of these reactive ions is very small, it first acts in the direction of lowering the viscosity of the liquid. In order to control the reaction of these divalent metal ions, it is also effective to use sodium citrate or sodium metaphosphate in combination for the purpose of sequestering metal.

  Furthermore, a low molecular sugar can be used as the viscosity expression inhibitor, and as the low molecular sugar, for example, sugar or erythritol can be used. By adding such low molecular weight carbohydrates to the paste at a high concentration, it is possible to suppress the viscosity of the paste, and when added to an object containing moisture, the viscosity or gelation is exhibited. Is done.
