US 2023/0054591 A1 · AGROCHEMICAL GEL COMPOSITIONS

Abstract

Improved aqueous herbicidal compositions comprising at least one water-soluble herbicide and a gel forming agent are provided. The compositions are generally characterized as pseudoplastic, elastic and having a relatively high stationary viscosity. The compositions provide enhanced foliar retention and resistance to drying thereby allowing for improved uptake of the herbicide into the plants and/or translocation within the plant in order to more effectively kill the plants at reduced application rates in kilograms of herbicide per hectare, even in the absence of a surfactant. Methods for confined application of the compositions of the invention to control the growth of unwanted plants are also provided.

Dependent claims

An aqueous agrochemical gel composition comprising:

(1) from 0.1 to 5 percent by weight on an acid equivalent basis of a water-soluble agrochemical component comprising at least one water-soluble agrochemical,
(2) from 0.1 to 5 percent by weight of a polymeric gel forming agent component comprising at least one polymeric gel forming agent, and
(3) from 85 to 98 percent by weight water
wherein tan (delta) of the gel composition is less than 1 as measured by oscillation frequency sweep rheometric measurements between about 0.1 and about 600 rad/sec at 0.2 Pa and 1 Pa as measured using a cone and plate viscometer method with a 60 mm 2° acrylic cone and plate at 20° C. and wherein the yield point of the gel composition is at least about 50 dyne/cm2.
