Abstract: This invention related to a novel class of 1,4-oxathiins bearing a substituted 3-imino group having a broad spectrum of fungicidal activity. The class of compounds is represented by formula (I): ##STR1## wherein: R.sub.n is each independently C.sub.1 -C.sub.12 linear or branched alkyl; halogen, trihalomethyl or C.sub.1 -C.sub.6 alkoxy;R' is hydrogen or C.sub.1 -C.sub.8 linear or branched alkyl;G is CH or N; andn is 0,1 or 2.Fungicidal compositions, methods of controlling fungi and methods for preparing the compounds are within the scope of this invention.

Abstract: A microbicide having the general formula ##STR1## wherein R is a halomethyl radical, or a methylene radical; W is cyclohexyl, phenyl or meta or para substituted phenyl wherein the substituents are C.sub.1 -C.sub.4 alkyl, halogen or nitro; X and Y is hydrogen, C.sub.1 -C.sub.4 alkyl, halogen or nitro; provided that when R is halomethyl n is 1 and when R is methylene n is 0.

Abstract: Substituted thiophenes of the following formula, some of which are new compounds, are useful in controlling certain pests, particularly mites: ##STR1## wherein A, Y and Z are various substituents such as phenyl and substituted phenyl.
