Abstract

Abstract Agrochemical formulations, especially herbicidal formulations, comprising water-in-oil emulsions of mean particle size below 10 microns wherein the oil phase is from 50 to 99% by weight, the aqueous phase being from 1 to 50% by weight and containing 1 to 25% by weight of a water-soluble agrochemical, especially a herbicide, the oil phase having a resistivity at 20° C in the range 10 6 to 10 10 ohm cm, and a viscosity at 20° C in the range 1 to 50 centistokes.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 120 words
An electrostatically sprayable ready-for-use formulation comprising a water-in-oil emulsion comprising finely divided droplets of mean diameter below 10 microns of an aqueous phase suspended in an oil phase, the oil phase comprising from 50 to 99% by weight of the composition and the aqueous phase comprising from 1 to 50% by weight of the composition, and having dissolved in it a water-soluble agrochemical comprising from 1 to 25% by weight of the composition, the formulation having a resistivity at 20°C in the range 1 x 10 6 to 1 x 10 10 ohm centimetres and a viscosity at 20°C of 1 to 50 centistokes, and being stabilised by from 0.1 to 10% by weight of the composition of an emulsifier.
Claim 2
Dependent Claim 120 words
An electrostatically sprayable ready-for-use formulation comprising a water-in-oil emulsion comprising finely divided droplets of mean diameter below 10 microns of an aqueous phase suspended in an oil phase, the oil phase comprising from 50 to 99% by weight of the composition and the aqueous phase comprising from 1 to 50% by weight of the composition, and having dissolved in it a water-soluble agrochemical comprising from 1 to 25% by weight of the composition, the formulation having a resistivity at 20°C in the range 1 x 10 6 to 1 x 10 10 ohm centimetres and a viscosity at 20°C of 1 to 50 centistokes, and being stabilised by from 0.1 to 10% by weight of the composition of an emulsifier.
Claim 3
Dependent Claim 14 words
A formulation as claimed in claim 1 in which the agrochemical is a herbicide.
Claim 4
Dependent Claim 52 words
A formulation as claimed in either of claims 1 or 2 in which the oil phase comprises from 80 to 99% by weight of the composition, the aqueous phase comprises from 1 to 20% by weight of the composition and the agrochemical comprises from 1 to 10% by weight of the composition.
Claim 5
Dependent Claim 29 words
A formulation as claimed in any of claims 1 to 3 in which the resistivity of the formulation is in the range 10 7 to 10 9 ohm centimetres.
Claim 6
Dependent Claim 25 words
A formulation as claimed in any of the preceding claims in which the viscosity at 20°C of the formulation is in the range 5-30 centistokes.
Claim 7
Dependent Claim 20 words
A formulation as claimed in any of the preceding claims in which the agrochemical is a bipyridylium herbicide, e.g. paraquat.
Claim 8
Dependent Claim 17 words
A formulation according to claim 1 substantially as herein described with reference to any of the Examples.
