Use of a tetramic acid compound according to formula (I) or (I′) with a second nematicide as a treatment for crop plants to combat and control nematodes in the soil of said crop plants.

The present invention relates to a compound of formula (I): wherein the substituents are as defined herein, and wherein the compound of formula (I) is optionally present as an agrochemically acceptable salt thereof. These compounds are thought to be suitable for use as herbicides. The invention therefore also relates to a method of controlling weeds, especially grassy monocotyledonous weeds, in crops of useful plants, comprising applying a compound of formula (I), or a herbicidal composition comprising such a compound, to the plants or to the locus thereof. ##STR00001##

At present, many herbicidal compositions have been developed and used, but it has been desired to develop a herbicidal composition having a wider herbicidal spectrum and high activity and thereby capable of controlling undesired plants.

The present invention provides a herbicidal composition comprising as active ingredients (a) tolpyralate and (b) tiafenacil.
