A pesticidal concentrate composition comprising a pesticidal component suspended in an oily component, the composition comprising 1-55% by weight of pesticide, 20-90% by weight of the oily component and 1-45% by weight of a surfactant component, and optionally water and optionally filler, the surfactant component comprising one or more stabilizing constituents comprising a C5-30 hydrocarbyl or hydrocarbylene chain carrying a group capable of forming hydrogen bonds with water, and optionally one or more other constituents selected from the group consisting of non-ionic and ionic surfactants, the stabilizing constituent being present in an amount of at least 4% by weight, calculated on the total amount of surfactant component in the composition.
Examples of stabilizing constituents are fatty alcohols and amino group-containing surfactants, especially ampholytes.
Pesticidal concentrate compositions comprising 1-55% by weight of finely ground dithiocarbamate or glyphosate suspended in 10-90% by weight of an oily component and comprising 1-50% by weight of a surfactant component, calculated on the total composition, may be prepared.
The pesticidal concentrate compositions are used in the preparation of ready-to-use-spray liquid, normally comprising 0.1-10% of concentrate and 90-99.9% of water.
