The present invention is further directed to methods of increasing the activity of imazosulfuron with the mixtures of the present invention. ## Claims ### Claim 1 An agricultural mixture comprising imazosulfuron, or a salt thereof, and a C16 to C18 fatty acid methyl ester adjuvant system, wherein the C16 to C18 fatty acid methyl ester adjuvant system comprises from about 60 to about 99% w/w of a C16 to C18 fatty acid methyl ester mixture, from about 0.1 to about 5% w/w of a dodecylbenzene sulfonate salt, from about 0.5 to about 4% w/w of at least one dodecylbenzene sulfonate salt solvent, from about 0.1 to about 10% w/w of at least one polyoxyethylene plant oil, and from about 0.1 to about 10% w/w of at least one polyoxyethylene sorbitan ester. ### Claim 2 (depends on 1) The mixture of claim 1 wherein the weight to volume ratio of imazosulfuron to the C16 to C18 fatty acid methyl esters adjuvant system is from about 1:1 to about 1:100. ### Claim 3 (depends on 1) The mixture of claim 1 wherein the mixture comprises from about 0.01 to about 1.0% w/v imazosulfuron. ### Claim 4 (depends on 1) The mixture of claim 1 wherein the mixture comprises from about 0.1 to about 10% v/v of the C16 to C18 fatty acid methyl ester adjuvant system. ### Claim 5 (depends on 1) The mixture of claim 1 wherein the C16 to C18 fatty acid methyl esters adjuvant system comprises from about 0.5 to about 10% w/w of the dodecylbenzene sulfonate salt. ### Claim 6 (depends on 1) The mixture of claim 1 wherein the dodecylbenzene sulfonate salt is calcium. ### Claim 7 (depends on 1) The mixture of claim 1 wherein the C16 to C18 fatty acid methyl ester adjuvant system comprises from about 1 to about 5% w/w of the at least one polyoxyethylene plant oil. ### Claim 8 (depends on 1) The mixture of claim 1 wherein the polyoxyethylene plant oil is castor oil. ### Claim 9 (depends on 1) The mixture of claim 1 wherein the adjuvant system comprises from about 1 to about 5% w/w of the at least one polyoxyethylene sorbitan ester. ### Claim 10 (depends on 1) The mixture of claim 1 wherein the polyoxyethylene sorbitan ester is sorbitan monotallate. ### Claim 11 A method of increasing the activity of imazosulfuron, or a salt thereof, by applying to an area in need of weed control imazosulfuron and a C16 to C18 fatty acid methyl ester adjuvant system, wherein the C16 to C18 fatty acid methyl ester adjuvant system comprises from about 60 to about 99% w/w of C16 to C18 fatty acid methyl ester mixture, from about 0.1 to about 5% w/w of a dodecylbenzene sulfonate salt, from about 0.5 to about 4% w/w of a dodecylbenzene sulfonate salt solvent, from about 0.1 to about 10% w/w of at least one polyoxyethylene plant oil, and from about 0.1 to about 10% w/w of at least one polyoxyethylene sorbitan ester. ### Claim 12 (depends on 11) The method of claim 11 wherein the imazosulfuron is applied at a rate of from about 50 to about 500 grams per hectare. ### Claim 13 (depends on 11) The method of claim 11 wherein the C16 to C18 fatty acid methyl ester adjuvant system is applied at a rate of from about 1,000 to about 5,000 milliliters per hectare. ### Claim 14 (depends on 11) The method of claim 11 wherein the weed controlled is selected from the group consisting of Hemp Sesbania (Sesbania herbacea), Common Barnyardgrass (Echinochloa crus-galli), Broadleaf Signalgrass (Brachiaria platyhylla), and Palmer Amaranth (Amaranthus palmeri). ### Claim 15 (depends on 14) The method of claim 14 wherein the weed controlled is Hemp Sesbania. ### Claim 16 (depends on 14) The method of claim 14 wherein the weed controlled is Common Barnyardgrass. ### Claim 17 (depends on 14) The method of claim 14 wherein the weed controlled is Broadleaf Signalgrass. ### Claim 18 (depends on 14) The method of claim 14 wherein the weed controlled is Palmer Amaranth. ### Claim 19 (depends on 11) The method of claim 11 wherein the area in need of weed control is occupied by rice, soybean, cotton, peanut or corn plants.
