Compounds of any one of formulae I-VII ##STR1## where is a single or double bond;

Fungicides

Compounds of the formula: ##STR1## where: A is oxygen or sulphur;

Fungicidal azole compounds

Compounds of any of one of formulae I-VII ##STR1## where  is a single or double bond;

Fungicidal compositions comprise a compound of formula I ##STR1## in which R.sup.1 and R.sup.3 are hydrogen, alkyl or alkenyl;

2-Cyano-3-benzylamino-2-propenoates, useful as fungicides

Sulphonanilides of formula ##STR1## and salts thereof, wherein R.sup.1 represents alkyl or certain other groups;

Compounds useful as pesticides

There are provided, as novel herbicides, the substituted pyrazolopyrimidines of the formula: ##STR1## where A represents -CO-NR.sup.6 - or -C(OR.sup.7).dbd.N-, and R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.6 and R.sup.7 are substituent groups as defined in the specification, and the salts and acid addition salts thereof. Processes for their preparation are provided, as also are herbicidal compositions containing them and methods of combating weeds in which they are used.

Substituted pyrazolopyrimidine compounds

Bis-amides of formula ##STR1## and salts thereof, where R.sup.2 and R.sup.3 are hydrogen; alkyl of up to 9 carbon atoms, alkenyl or alkynyl of up to 4 carbon atoms, or aryl, groups optionally substituted by certain radicals; or cycloalkyl of 3-7 carbon atoms; and R.sup.1 and R.sup.4 are as R.sup.2 and R.sup.3 or amino groups optionally substituted by certain radicals, are fungicides, especially against soil borne fungal diseases of plants.

Bis-amide fungicidal compounds

There are provided substituted benzimidazoles of the formula: ##STR1## (wherein at least two of the radicals X are halogen and the remainder are hydrogen, and R represents an alkyl radical of 1 to 6 carbon atoms), processes for preparing them, and compositions containing them. The compounds possess anti-protozoal activity.

Halogenated alkylsulphonyl-benzimidazoles

2-Trifluoromethylbenzimidazoles having a sulphamoyl or substituted sulphamoyl substituent on the benzene ring combat mammalian parasites, for example liver fluke in mammals e.g. sheep, and cattle tick and sheep blowfly.
