Herbicide composition including 2,4-D and Dicamba in acid form formulated together as microemulsion

Disclosed is a formulation having at least two auxinic hormonal herbicides, normally used separately in applications to control a wide variety of broadleaf weeds, present in fields without cultivation, during chemical fallows, and in crops such as winter cereals, corn and sorghum, that together have a synergistic effect on weed control. This effect is even greater in the microemulsion formulation that includes at least the two active ingredients, if compared to the conventional tank mix, this greater efficiency being attributed to the chemical compatibility that exists in the "ready mix" achieved by the correct choice of emulsifiers to maintain active emulsion, physical compatibility that translates into greater biological efficacy. Preferably, the herbicidal composition has at least: (i) from 7.5% to 40% of 2,4-D in its acidic form; and (ii) from 1.2% to 35% of Dicamba in its acid formic as active ingredients, formulated together in a microemulsion type formulation.
