Description

AGRICULTURAL COADYUVANTE BACKGROUND OF THE INVENTION The present invention, in general, refers to agricultural adjuvants it is known that different pesticides such as insecticides, insect repellents, fungicides, bactericides, herbicides and plant growth regulators can be formulated in different agricultural products for use in crops and crops. Ornamental plants, to control weeds, insects and the like. These products can be applied in the form of a liquid or a semi-solid dispersion. The successful use of any of the pesticides depends on the proper formulation in a preparation that can be easily combined with water in a ready-to-use form in application on an agricultural substrate with safety for the applicator, animals and plants. The preparation and use of these formulations usually requires the preparation of them in concentrated form. Thus, the use of auxiliary agents such as solvents, emulsifiers, wetting agents and dispersants is usually necessary. The preparation of these pesticide concentrates, however, sometimes presents certain formulation problems due to the incompatibility of the pesticide component with other components combined with it such as electrolytes, hard water and fertilizers.
