Stable concentrated pesticidal suspension

An emulsifiable pesticidal suspension concentrate composition is provided comprising (a) a pesticidally effective amount of a liquid pesticide of low solubility in water, for example a chloroacetamide herbicide such as acetochlor, (b) a pesticidally effective amount of a solid particulate pesticide, more particularly a salt-forming pesticide, for example a glyphosate herbicide, in solid particulate form, dispersed in the liquid pesticide, (c) a stabilizing amount of a suspension aid, (d) an emulsifying agent in an amount sufficient to emulsify the concentrate composition in a suitable volume of water to form a dilute sprayable composition, and (e) zero to an assay adjusting amount of an inert liquid in which the liquid pesticide is soluble or miscible. The concentrate composition is substantially non-aqueous. The liquid and solid pesticides are selected to be chemically compatible with each other. By substantial elimination of water and inert organic solvents according to the invention, suspension concentrate compositions can be provided having a very high concentration of active ingredients.
