Abstract
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; PA0 Py is an optionally substituted pyrazole ring; PA0 W is O or NR.sup.1 ; where R.sup.1 is hydrogen or lower alkyl; PA0 X is (CH.sub.2).sub.n, CH.dbd.CH, CH(OR.sup.5)CH.sub.2, COCH.sub.2 ; PA0 where n is 0, 1 or 2; PA0 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; PA0 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 ; PA0 R.sup.15+ is an agriculturally acceptable cation and R.sup.14- is an agriculturally acceptable anion. PA0 R.sup.5, R.sup.8 and R.sup.9 are independently selected from H or an optionally substituted alkyl, aryl, alkenyl…
