A herbicidal compound of formula (I): ##STR1## in which the dotted line indicates the presence of two double bonds arranged so as to form a fused hetero-aromatic ring system; Py is an optionally substituted pyrazole ring; W is O or NR.sup.1 ; where R.sup.1 is hydrogen or lower alkyl; X is (CH.sub.2).sub.n, CH.dbd.CH, CH(OR.sup.5)CH.sub.2, COCH.sub.2 ; where n is 0, 1 or 2; R.sup.2 and R.sup.3 are independently selected from H, optionally substituted alkyl, alkenyl or alkynyl, halogen, NR.sup.6 R.sup.7, or R.sup.2 and R.sup.3 together with the carbon to which they are attached form an optionally substituted alkenyl or cycloalkyl group; R.sup.4 is CO.sub.2 R.sup.8, CN, COR.sup.8, CH.sub.2 OR.sup.8, CH(OH)R.sup.8, CH(OR.sup.8)R.sup.9, CSNH.sub.2, COSR.sup.8, CSOR.sup.8, CONHSO.sub.2 R.sup.8, CONR.sup.10 R.sup.11, CONHNR.sup.10 R.sup.11, CONHN.sup.+ R.sup.10 R.sup.11 R.sup.12 R.sup.14-, CO.sub.2.sup.- R.sup.15+ or COON.dbd.CR.sup.10 R.sup.11 ; R.sup.15+ is an agriculturally acceptable cation and R.sup.14- is an agriculturally acceptable anion. R.sup.5, R.sup.8 and R.sup.9 are independently selected from H or an optionally substituted alkyl, aryl, alkenyl or alkynyl group; R.sup.6, R.sup.7, R.sup.10, R.sup.11 and R.sup.12 are independently selected from H or an optionally substituted alkyl, alkenyl, aryl or alkynyl group; or any two of R.sup.6, R.sup.7, R.sup.10, R.sup.11 and R.sup.12 together with the atom to which they are attached form a cycloalkyl or heterocyclic ring. Processes for the preparation of these compounds and compositions containing them are also described.
