<p>The invention relates to pesticidal formulations in concentrate form containing herbicidal 2,6 - dinitroaniline derivatives. There are prepared herbicidal fonmulations in concentrate form which are aqueous emulsions containing 10% to 75% by weight of a herbicidal 2,6 - dinitroaniline derivative, such as trifluralin, up to 60% by weight of water - immiscible solvent, the herbicide and the solvent forming a homogeneous disperse phase, 0.5% to 10% by weight of an emulsifying agent and 15% to 70% by weight of an aqueous solution of an inorganic salt, such as sodium chloride. The concentration of the inorganic salt in the aqueous solution is at least 5% by weight. The aqueous solution may additionally contain urea. The formulations are readily dispersible in large volumes of water in preparation for spraying, and present a reduced fire risk compared with conventional concentrated formulations of 2,6 - dinitroaniline herbicides.</p> |
