Abstract RU 2667765 C2

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. Composition of an aqueous suspension is an agrochemical, it contains I) at least one water-soluble salt having a solubility in water at 25 °C, equal to at least 20 %, II) at least one thickening aqueous solution of the polymer electrolyte, capable of thickening the composition, selected from the group consisting of xanthan gum, xanthan gum derivatives, guar gum, guar gum derivative or a mixture thereof, III) at least one water-insoluble solid agrochemical, selected from the group consisting of methyl ethyl hydroxyethylcellulose, a water-insoluble pesticide having a solubility in water at 25 °C of less than 2 wt%, a water-insoluble growth regulator having a solubility in water at 25 °C of less than 2 wt%, water-insoluble micronutrient having a solubility in water at 25 °C of less than 2 wt%, and combinations and mixtures thereof, and the balance is water. Composition is thinned by shearing and has a viscosity of less than 30,000 cP at 25 °C, measured with a Brookfield DV-II Pro viscometer using spindle No. 64 at 60 rpm, and in which the concentration of the water-soluble salt ranges from 15 to 70 wt%, the concentration of the thickening aqueous solution of the polymer electrolyte ranges from 0.1 to 2 wt%, the concentration of the water-insoluble solid agrochemical is 3 to 50 wt%, water is added to 100 wt%.

EFFECT: invention allows to increase the composition stability.
