Embodiment 1

[0292] Preparation of embodiment 1-glyphosate composition

[0293] The following glyphosate compositions were prepared according to the following procedure

[0294] program :

[0295] 1) Mix water and surfactant system 1. get slurry

[0296] 2) Add 50% of the glyphosate compound and neutralize with a molar equivalent of isopropylamine to achieve 50% of the final amount comprising isopropylamine salt

[0297] 3) Add remaining 50% of glyphosate compound and neutralize with molar equivalent of isopropylamine

[0298] 4) Add additive compound

[0299] The viscosity of the composition is measured at 25°C using an RVT Brookfield Viscosimeter, Spindle No. 2, at 10 rpm.

[0300] Crystallization was evaluated after 1 week at room temperature ("RT").

[0302] Example 2 - Preparation of Blends

[0303] 68% by weight (as is) of Surfactant System 2 and 32% by weight of Lactic Acid K solution were mixed together to obtain the following blend. The viscosity of the composition is measured at 25°C using a RVTBrookfield Viscosimeter, Spindle No. 2, at 20 rpm.

Abstract

The present invention relates to herbicidal compositions comprising an aminophosphate or aminophosphonate salt, particularly to herbicidal compositions comprising a relatively high amount of aminophosphate or aminophosphonate salt. The compositions comprise an additive compound which is a salt.

Description

technical field [0001] The present invention relates to herbicidal compositions comprising phosphoramidates or phosphonamidates, and more particularly to herbicidal compositions comprising relatively high levels of phosphoramidates or phosphonamidates and surfactant-containing compositions of matter. Background technique [0002] Among the various forms of glyphosate-containing compositions, concentrated liquid compositions that can be diluted by the end user, usually a farmer, are beneficial. In general, the higher the glyphosate concentration, the better it is because the end user can set the use concentration (amount of active applied to the field) by adjusting the dilution ratio and can avoid extensive handling of the product (e.g., higher concentration, the lower the weight). [0003] Concentrated compositions may comprise high levels of glyphosate, water and at least one surfactant compound which may be used as a formulation aid (dispersion, dissolution and / or stabili...
