A class of compounds useful for providing long-term control of pests, such as insects, nematodes and acarids, having the structural formula: ##STR1## where R is lower alkyl, phenyl, substituted phenyl, naphthyl or substituted napthyl; R.sup.1 is hydrogen or C.sub.1 -C.sub.6 alkyl; R.sup.2 is C.sub.1 -C.sub.6 alkyl or phenyl; R.sup.3 is C.sub.1 -C.sub.6 alkoxy, C.sub.1 -C.sub.6 alkyl or C.sub.1 -C.sub.6 alkylthio; R.sup.4 is C.sub.1 -C.sub.6 alkoxy, C.sub.1 -C.sub.6 alkylthio, C.sub.1 -C.sub.6 alkylamino or C.sub.1 -C.sub.6 dialkylamino; and X is oxygen or sulfur.

Oxime phosphate pesticidal compounds, compositions and methods

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;

Fungicidal 3-imino-1,4-oxathiins

A method of stimulating the growth of desirable plants comprising applying a plant growth stimulatory amount of certain 2-methylhalide or 2-methylthiophosphate substituted 1,3,4-oxadiazole compounds.

Method of stimulating the growth of plants employing substituted

A compound of the formula ##STR1## wherein R is allyl, halocyclopropyl, C.sub.3 -C.sub.5 alkoxycarbonylmethyl, C.sub.7 -C.sub.9 aralkyl, styryl, phenyl, naphthyl, furanyl, pyridyl, thienyl, phenyl substituted with halogen, C.sub.1 -C.sub.4 alkyl, trihalomethyl, C.sub.1 -C.sub.4 alkoxy, trihalomethoxy, trihalomethylthio, C.sub.1 -C.sub.4 alkylthio, phenyl, phenoxy, cyano or nitro or C.sub.7 -C.sub.9 aralkyl substituted with halogen, C.sub.1 -C.sub.4 alkyl, trihalomethyl, C.sub.1 -C.sub.4 alkoxy, trihalomethoxy, trihalomethylthio, C.sub.1 -C.sub.4 alkylthio, phenyl, phenoxy, cyano or nitro; R.sup.1 is hydrogen, C.sub.1 -C.sub.3 alkyl, C.sub.7 -C.sub.9 aralkyl, phenyl, C.sub.7 -C.sub.9 aralkyl substituted with halogen, C.sub.1 -C.sub.4 alkyl, trihalomethyl, C.sub.1 -C.sub.4 alkoxy, trihalomethoxy, trihalomethylthio, C.sub.1 -C.sub.4 alkylthio, phenyl, phenoxy, cyano or nitro or phenyl substituted with halogen, C.sub.1 -C.sub.4 alkyl, trihalomethyl, C.sub.1 -C.sub.4 alkoxy, trihalomethoxy, trihalomethylthio, C.sub.1 -C.sub.4 alkylthio, phenyl, phenoxy, cyano or nitro, however, if R is substituted phenyl or substituted C.sub.7 -C.sub.9 aralkyl, then R.sup.1 cannot be hydrogen; R.sup.2 is C.sub.1 -C.sub.4 alkyl, however, if R or R.sup.1 is 4-chlorophenyl, R.sup.2 cannot be isopropyl; and X, Y and Z are the same or different and are oxygen or sulfur, is disclosed. A method is provided for protection against pests by employing a pesticidally effective amount of the compound above. A composition comprising the compound above and an inert carrier therefor, for pesticidal use, is also taught. The disclosure also recites a compound of the formula ##STR2## where R and R.sup.1 have the meanings of the first mentioned compound. The compound, effective as an intermediate in the synthesis of the above compound, is produced by the reaction of a compound of the formula ##STR3## where R has the meanings given above with a compound of the formula

Certain 2-(pyridyl or

Selective herbicidal 2-(alpha-chloromethylsulfonyl) pyridine-1-oxides, e.g., 2-(alpha-phenyl-alpha-chloromethylsulfonyl) pyridine-1-oxide controls weed grasses without injury to such crops as cucumber.
