1. An agrochemical composition comprising
(a) one or more biocides, and
(b) one or more esterified alkoxylation products of di- and/or oligosaccharides comprising C6-C22 fatty acid esters of adducts of ethylene oxide and/or propylene oxide to di- and/or oligosaccharides.
2. The composition according to claim 1 , wherein said one or more biocides (component a) are selected from the group consisting of insecticides, herbicides, and or fungicides.
3. The composition according to claim 1 wherein said one or more biocides (component a) are selected from the group consisting of oxyfluorfen, glyphosate, tebucanozol, desmedipham, phenmedipham, ethofumesat and their mixtures.
4. The composition according to claim 1 wherein said one or more alkoxylation products (component b) comprise adducts of ethylene oxide and/or propylene oxide to esters of di- and/or oligosaccharides selected from the group consisting of saccharose, maltose, maltotriose, and degradation products of celluloses, starches or waste material from sugar industry.
5. The composition according to claim 1 wherein said one or more alkoxylation products (component b) comprise adducts of on average 1 to 100 mol ethylene oxide and/or 1 to 100 mol propylene oxide to esters of di- and/or oligosaccharides.
6. The composition according to claim 1 wherein said one or more alkoxylation products (component b) comprise adducts of on average 10 to 50 mol ethylene oxide and/or 1 to 10 mol propylene oxide to saturated or unsaturated C8-C18 esters of saccharose.
7. The composition according to claim 1 wherein said one or more alkoxylation products (Component b) comprise saccharose +10EO octanoate/decanoate or saccharose+40EO+6PO tetraoleate.
8. The composition according to claim 1 comprising:
(a) 10 to 50% b.w. biocides,
(b) 1 to 20% b.w. alkoxylation products of di- and/or oligosaccharide esters, and
(c) 0 to 80% b.w. auxiliary agents,
on condition that the amounts add with water up to 100% b.w.
9. The composition according to claim 1 further comprising as component (c) one or more auxiliary agents selected from the group consisting of fatty acid dialkyl amides, fatty acids, fatty alcohols, fatty alcohol polyglycolethers, end-capped fatty alcohol polyglycol ethers, and alkoxylated vegetable oils, alkyl benzenesulfonates, alkyl sulfates, alkyl ether sulfates, citric acid esters of ethoxylated fatty alcohols and fatty acid monoglycerides.
10. A method of producing agrochemical compositions, the method comprising providing an alkoxylation product of di- and/or oligosaccharide esters comprising adducts of ethylene oxide and/or propylene oxide to C6-C22 fatty acid esters of di- and/or oligosaccharides and mixing the adducts of ethylene oxide and/or propylene oxide to C6-C22 fatty acid esters of di- and/or oligosaccharides with one or more biocides to form the agricultural composition of claim 1 , wherein the alkoxylation product of di- and/or oligosaccharide esters is effective as a solvent, an emulsifier, an adjuvant, a tank-mix additive, and/or a carrier medium of the one or more biocides.
11. The agricultural composition of claim 1 , wherein the one or more esterified alkoxylation products of di- and/or oligosaccharide esters are made by subjecting alkoxylated saccharides to transesterification with the C6-C22 fatty acid esters, where a transesterification catalyst is selected from the group consisting of: sulphuric or sulphonic acids with an oxidation value of sulphur of less than 6 or their salts, and phosphoric or phosphonic acids with an oxidation value of phosphor of less than 5 or their salts.
