Abstract: Compounds of formula I ##STR1## where A is OH, B is H, C.sub.1-4 alkyl optionally substituted by C.sub.1-4 alkoxy carbonyl, C.sub.2-4 alkenyl, CONR.sub.2 or COR.sub.4 R.sub.1 is H, R.sub.2 is C.sub.1-4 alkyl, and R.sub.4 is C.sub.1-4 alkyl, or phenyl, optionally substituted by carboxy have pesticidal and especially fungicidal activity. Many of the compounds are novel and these compounds per se, form part of the invention.

Abstract: Compounds are disclosed having fungicidal activity and are of general formula I ##STR1## where at least three of A, C, D and E are --CX.dbd. and the other is --CX.dbd. or --N.dbd., where X is hydrogen, C.sub.1-8 -alkyl (optionally substituted by halogen), halo, nitro or phenoxy, in which the phenyl is optionally substituted by one or more groups selected from halo and trifluoromethyl;R.sup.1 is --SO.sub.2 R.sup.3 or ##STR2## and R.sup.2 is ##STR3## where R.sup.6 is hydrogen, C.sub.1-8 -alkyl (optionally substituted by one or more groups selected from halogen and hydroxy), C.sub.1-8 -alkanoyl, benzoyl, cyclohexylcarbonyl or aminocarbonyl (in which the amino is substituted by benzoyl or chlorobenzenesulphonyl);R.sup.3, R.sup.4, and R.sup.5 may be the same or different and have the meanings given to R.sup.6 or can be di-C.sub.1-8 -alkylamino; and Z is oxygen or sulphur; and when R.sup.1 is ##STR4## R.sup.2 can also be --CN.

Abstract: There are described compounds of the formula I, ##STR1## in which R.sup.5 is methyl or halomethyl,R.sup.2 is --CN, --CONRyRz, --COOR.sup.6 or --COSR.sup.6,R.sup.1 and R.sup.6 each represent hydrogen, a cation or an optionally substituted alkyl, alkenyl, alkynyl or aryl,Ry and Rz each represent hydrogen, alkyl or aryl,A represents hydrogen, orA and one of --XR.sup.3 and --ZR.sup.4 together form a double bond, and the other of --XR.sup.3 and --ZR.sup.4 represents --OR.sup.10 or --NHR.sup.11 in which R.sup.10 is alkyl or acyl and R.sup.11 is alkyl, aryl or acyl,X and Z (when not forming part of a double bond with A), which may be the same or different, each represent oxygen, sulphur or a group --NR.sup.7 --,R.sup.7 represents hydrogen or alkyl,R.sup.3 and R.sup.4 each represent alkyl or R.sup.3 and R.sup.4 together form an optionally substituted alkylene or arylene chainor --XR.sup.3 and --ZR.sup.4 together form .dbd.C(CN).sub.2 or .dbd.NR.sup.8, in which R.sup.

Abstract: There are described pesticidal compositions comprising one or more compounds of the formula I, ##STR1## in which Ra is a group R.sup.2 or --OR.sup.2,E is oxygen or sulphur,Rm is --O.sup..crclbar. M.sup..sym. or --NRyRz,M.sup..sym. is one equivalent of an agriculturally acceptable cation,R.sup.1 and R.sup.2, which may be the same or different, each represent hydrogen, alkyl, alkenyl, alkynyl or aryl; the alkyl, alkenyl, alkynyl or aryl optionally being substituted by one or more halogen, alkoxy, nitro, alkyl, --CF.sub.3, nitrile, or carboxylic acid or a salt, ester, or amide thereof, andRy and Rz, which may be the same or different, each represent hydrogen or alkyl,or an agriculturally acceptable derivative thereof.There are also described methods for making and using compounds of formula I.
