ENHANCED HERBICIDE COMPOSITIONS

A CONCENTRATE HERBICIDAL COMPOSITION IS PROVIDED COMPRISING A FIRST HERBICIDE THAT IS ANIONIC, FOR EXAMPLE THE HERBICIDE GLYPHOSATE, AND A SECOND HERBICIDE THAT ELICITS A VISIBLE SYMPTOM OF PHYTOTOXICITY IN A PLANT WITHIN ABOUT 4 DAYS AFTER APPLICATION TO FOLIAGE OF THE PLANT.THE CONCENTRATE COMPOSITION FURTHER COMPRISES (A) AN ALKYL ETHER SURFACTANT COMPONENT CONSISTING OF ONE OR MORE SURFACTANTS EACH HAVING THE FORMULA WHEREIN R12 IS AN ALIPHATIC SATURATED OR UNSATURATED HYDROCARBYL GROUP HAVING ABOUT 16 TO ABOUT 22 CARBON ATOMS, N IS AN AVERAGE NUMBER OF ABOUT 5 TO ABOUT 100, M IS AN AVERAGE NUMBER OF 0 TO ABOUT 5, ONE R IN EACH -((CHR)2O)- GROUP IS HYDROGEN AND THE OTHER R IS METHYL, AND R13 IS A HYDROGEN, C1-4 ALKYL OR C2-4 ACYL GROUP; AND (B) AN AMINE SURFACTANT COMPONENT. THE WEIGHT RATIO OF THE ALKYL ETHER SURFACTANT COMPONENT TO THE AMINE SURFACTANT COMPONENT IS ABOUT 1: 10 TO ABOUT 10: 1; AND THE ALKYL ETHER AND AMINE SURFACTANT COMPONENTS ARE PRESENT IN TOTAL IN AN ADJUVANT AMOUNT OF ABOUT 0.05 TO ABOUT 0.5 PARTS BY WEIGHT PER PART BY WEIGHT OF THE FIRST HERBICIDE, EXPRESSED AS ACID EQUIVALENT.ALSO PROVIDED ARE A PLANT TREATMENT COMPOSITION COMPRISING A FIRST HERBICIDE, A SECOND HERBICIDE, AN ALKYL ETHER SURFACTANT COMPONENT AND AN AMINE SURFACTANT COMPONENT, ALL AS DESCRIBED ABOVE,DISSOLVED OR DISPERSED IN WATER, AND A HERBICIDAL METHOD COMPRISING APPLYING SUCH A PLANT TREATMENT COMPOSITION TO FOLIAGE OF A PLANT.(FIG 1)
