Pesticidal concentrate compositions
First Claim
1. A pesticidal concentrate composition which can be reconstituted with water to form a storage-stable pesticidal emulsion useful for spraying, the emulsion being substantially free of gels, lumps, precipitates, and sediments, said pesticidal concentrate composition comprising:
- (a) 1-55% by weight of a solid particulate or liquid pesticidal component, which is dispersed in (b) and (c);
(b) 20-90% by weight of an oily component selected from the group consisting of petroleum fractions, vegetable oils, and esters of mono- or polyalcohols having 2-6 hydroxy functions with mono- or polycarboxylic acids, the oily component being liquid at normal temperatures and immiscible with water in a ratio of 1;
10-10;
1 by weight and comprising at least 67% by weight of hydrocarbyl or hydrocarbylene, based on the total chemical composition of the oily component; and
(c) 1-45% by weight of surfactants, the surfactants comprising at least one non-ionic surfactant and at least one stabilizing constituent which is a fatty alcohol selected from the group consisting of mono- and dialcohols having a C5-30 hydrocarbyl or hydrocarbylene chain, the stabilizing constituent(s) being present in an amount of 6-60% by weight based on the total amount of surfactant(s), including stabilizing constituent(s), present.

Abstract
A pesticidal concentrate 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 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.
