HERBICIDAL COMPOSITION

To provide a herbicidal composition and a method for its application, whereby the effect of a herbicidally active ingredient is improved to reduce the environmental load on a site where the herbicide is applied or the periphery thereof, more than ever, and its dose can be reduced. A herbicidal composition comprising (1) a compound represented by the formula (I) or its salt: where T and Z are as defined in the specification, and (2) a polyoxyalkylene alkyl ether phosphate or its salt. A method for controlling undesired plants or inhibiting their growth, by applying the herbicidal composition.

PROCESS FOR THE PRODUCTION OF CYCLIC DIKETONES

The present invention relates to a process for the preparation of compounds of formula (I), wherein the substituents are as defined in claim 1, by reacting a compound of formula (II), either with a chlorination or bromination agent or with a compound of formula (III) CI-SO2R9, R9 being C1-C4alkyl, C1-C4haloalkyl, phenyl or C1-C4alkyl-substituted phenyl, to form the compound of formula (IV), reacting the compound of formula (IV) with a compound of formula (V) M+-O--C(O)-Y, wherein Y is as defined above and M+ is the hydrogen cation or an alkali metal ion, alkaline earth metal ion or ammonium ion, to form the compound of formula (VI) and treating that compound with a cyanide source in the presence of a base.
