Xylachlor is a selective herbicide, used to pre-emergently control annual grasses on cereals, wheat, soy and rice. It is an anilide and a (chloro)acetanilide. As of 2023 it is considered obsolete, but may still be in use. [1]

It was manufactured by American Cyanamid under the "Combat" trademark, [1] registered in August 1979 and expired (by non-renewal) in 1986. [2]

Compared to the fellow acetanilides alachlor, acetochlor and metolachlor, xylachlor had the weakest control of pigweed and setaria, though the greatest selectivity. [3] Xylachlor is also less detrimental to sorghum, but this is offset by the need for higher application rates to achieve similar weed control. [4]

Xylachlor's safety is not well studied. Prediction software indicates that it may be a class 3 highly toxic compound, mutagen or carcinogen, although other software predictions disagree. [5]
