[0105] Example 3 - Initial Example of Co-formulation of the Invention and Demonstrated in Field

[0106] An oil-based suspension co-formulation of diuron and thiadiuron according to the invention is prepared as follows:

[0107] table 3

[0108]

[0109] First, through the SILVERSON high shear mixer, by mixing 10g 38 (ELEMENTIS) dispersed in 86.66g , to prepare a premixed 'masterbatch' of activated hydrophobically modified hectorite. With continuous shearing, to the resulting homogeneous dispersion was added 3.34 g AG 1555 until a homogeneous gel-like mass is obtained. Leave it idle.

[0110] Then, according to Table 3, the required amount of The 2510 dispersant is dissolved in a certain amount of thidiazuron concentration that will allow about 7% (weight to weight ratio) middle. Diuron and Thidiazuron were then technically dispersed in the resulting mixture using a SILVERSON mixer under high shear. Continue this until a homogeneous mixture is obtained.

Abstract

An agricultural co-formulation comprising: an effective amount of at least one plant growth regulator, or at least one plant growth regulator and an additional biologically active ingredient, in a comminuted form having an average particle size in the range of from 1 to 12 microns; at least one oil; at least one oil-soluble surfactant dispersing agent; and at least one emulsifying agent, wherein the final concentration of the at least one plant growth regulator, or at least one plant growth regulator and an additional biologically active ingredient, is optionally adjusted by adding additionaloil and one or more rheology modifiers and / or activation agents as required to substantially stabilise the co-formulation; and wherein the efficacy of the plant growth regulator is substantially maintained or improved; and one or more methods of making the co-formulation.

Description

field of invention [0001] The present invention generally relates to the co-formulation of at least one plant growth regulator, or at least one plant growth regulator and additional bioactive ingredients, or mixtures thereof, with various oils to form agricultural oil-based dispersions or oil dispersions body. More specifically, the present invention relates to an oil dispersion containing a plant growth regulator, or a mixture of a plant growth regulator and a herbicide, which oil dispersion can subsequently be used as a defoliant. In the following the invention will be conveniently described with respect to the use of the oil dispersion as a defoliant, in particular for cotton crops. However, it should be understood that the invention is not limited to this application. Background of the invention [0002] Defoliation of cotton crops is a well-established practice that has been practiced commercially for many years. Once defoliation is initiated, mechanical harvesting o...
