Abstract

The present invention relates to a solid herbicidal composition comprising: i. mesotrione; ii. at least one arene sulfonate condensed with formaldehyde (e.g. sodium alkylnaphthalene sulfonate condensed with formaldehyde); and iii. an acidifying agent. The present invention further provides a method of controlling weeds at a locus comprising diluting the solid herbicidal composition of the present invention and applying to the locus a weed controlling amount of the diluted herbicidal composition.

First claim

The invention claimed is:

1. A solid herbicidal composition comprising:
i. from 1% to 50% w/w of mesotrione;
ii. from 1% to 25% w/w of at least one alkylnaphthalene sulfonate condensed with formaldehyde; and
iii. from 0.5% to 5% of an acidifying agent selected from the group consisting of citric acid, phosphoric acid and mixtures thereof.

2. The solid herbicidal composition according to claim 1 , which is a wettable granule.

3. The solid herbicidal composition according to claim 1 , which further comprises at least one additional herbicide selected from the group consisting of sulfonylurea herbicides, triazine herbicides and auxin herbicides.

4. The solid herbicidal composition according to claim 1 , wherein the at least one alkylnaphthalene sulfonate condensed with formaldehyde is present in an amount from 2.5% to 10% w/w.
