Compounds of the general formula:
which are 1-dimethylcarbamoyl-3-substituted-5-substituted-1H-1,2,4-triazoles of specified 3- and 5-substitution, and agronomically acceptable salts thereof, are pesticidally, especially insecticidally active; further some are molluscicidally active and some are plant growth regulants. They are provided in insecticidal, molluscicidal and plant growth regulant compositions together with agronomically acceptable diluents or carriers and may be applied to insects, molluscs or loci to be freed or protected from attack by insects or molluscs or applied to plants to regulate their growth. The compounds may be prepared by reacting an appropriate 3-t-butyl-5- substituted-1 H-1,2,4-triazole with a halo compound of the formula
The reactant triazole may itself be prepared by S-alkylating the corresponding 5-thio compound with an appropriate compound.
