Sulfonylsemicarbazide derivatives and preservative composition for

A novel compound represented by the formula (I) ##STR1## wherein R represents a lower alkyl group having 1 to 4 carbon atoms which has an intense microbicidal activity over a wide range of microorganisms and is applicable to a microbicide.

N-alkylbenzenesulfonylcarbamoyl-5-chloroisothiazole derivatives and

Triiodoallyl- or iodopropargyl-substituted tetrazole compounds which are prepared by reacting substituted tetrazole compound with reactive derivatives of corresponding triiodoallyl alcohol or iodopropargyl alcohol or by iodinating propargyltetrazole compounds, as well as antibacterial and antifungal compositions for medicinal, agricultural and industrial fields which contain as active ingredient said tetrazole compounds.

Iodoallyl and iodopropargyl substituted tetrazoles and anti-microbial

Triiodoallyl- or iodopropargyl-substituted heterocyclic aromatic compounds which can be prepared by reacting unsubstituted- or substituted nitrogen-containing heterocyclic compounds with corresponding iodine containing alcohol reactive derivatives in the presence of a base in an inert organic solvent. These new heterocyclic aromatic compounds have remarkable antibacterial and antifungal activities and are useful as antibacterial and antifungal agents in medicinal, agricultural and industrial fields.

The present invention relates to pyrazolylpyrimidine derivatives of the formula ##STR1## wherein X, R.sub.1, R.sub.2 and R.sub.3 are as herein defined. These compounds are useful as fungicides in agriculture and horticulture.
