Novel compounds having the formula ##STR1## wherein R is lower alkyl having 1 to 6 carbon atoms, have shown utility as insecticides and miticides.

Phosphonodithioylacetyl phenyl aminoacid ethyl esters

This invention relates to the herbicide N,N'-(N''-isopropylcarbamyl,N'''-isopropylcarbamyl)-S-ethylisothiourea, its use and process for making the same.

Isothiourea herbicidal composition

Lepidoptericidal and herbicidal active compounds having the generic formula ##STR1## wherein R, R.sup.1, R.sup.2 and R.sup.3 are as disclosed herein. In general, these compounds show enhanced lepidoptericidal activity and show reduced phytotoxic effect on crops to be protected from the lepidoptera.

Lepidoptericidal isothiourea compounds

A method of increasing the yield of legumes (soybeans) utilizing a compound of the formula ##STR1## wherein R.sub.1 is selected from the group consisting of --CH.sub.3, --C.sub.2 H.sub.5, --C.sub.3 H.sub.7 and --C.sub.4 H.sub.9, and R.sub.2 and R.sub.3 are independently selected from the group consisting of --OCH.sub.3, --OC.sub.2 H.sub.5 and --OC.sub.3 H.sub.7.

Method of increasing the yield of legumes utilizing O,O-dialkyl

A method of increasing the yield of legumes (soybeans) utilizing a compound of the formula ##STR1## wherein R.sub.1 and R.sub.2 are independently selected from the group consisting of --OCH.sub.3, --OC.sub.2 H.sub.5, --OC.sub.3 H.sub.7, and --OC.sub.4 H.sub.7.

Method of increasing the yield of legumes utilizing

A method of increasing the yield of legumes (soybeans) utilizing a compound of the formula ##STR1##

Method of increasing the yield of legumes utilizing D- or

Herbicidally active thiolcarbamates are employed in combination with certain N-methylcarbamoyloxy benzaldehyde imines having the formula ##STR1## in which R.sup.4 is selected from the group consisting of chlorophenyl, chlorophenylthiomethylphenyl, acetoxy, and ##STR2## where R.sup.5 is selected from the group consisting of phenyl, pyridyl, and cyanomethyl, and n is zero or one. In a typical application, the imine is included in sufficient quantity to lessen the rate of soil degradation of the thiolcarbamate. As a result, the herbicidal effectiveness of the thiolcarbamate is enhanced and prolonged, rendering a single application of the herbicide effective over a longer period of time.

N-Methylcarbamoyloxy benzaldehyde imine herbicide extenders

Compounds having the formula ##STR1## wherein R is lower alkoxy or alkyl having from 1 to 6 carbon atoms, and preferably 1 to 3 carbon atoms and most preferably 1 carbon atom, R.sub.1 is lower alkoxy having from 1 to 6 carbon atoms, preferably 2 to 4 carbon atoms, and most preferably 2 carbon atoms, have shown utility as insecticides and miticides.

Phosphonodithioylacetylamino phenyl pyrazoles

A method of increasing the yield of legumes (soybeans) utilizing a compound of the formula ##STR1## wherein R is selected from the group consisting of --H, --CH.sub.3, --C.sub.2 H.sub.5 and --C.sub.3 H.sub.7.

Novel compounds having the formula ##STR1## in which R is lower alkyl, R.sub.2 is thio-lower alkyl or thio-lower alkenyl, R.sub.3 is hydrogen or lower alkyl and X is oxygen or sulfur, provided that when X is oxygen, R is lower alkoxy, have shown utility as insecticides and miticides and in some cases as plant growth regulators.

S-Alkyl and alkenyl-thiophenylacetamido thiophosphates and phosphonates

Novel biocidal S-aminoalkyl isothiourea compounds have the general structural formula ##STR1## wherein X is halogen; R is a straight or branched chain alkyl radical containing 5 to 20 carbon atoms; R.sub.1 is selected from the group consisting of alkyl containing 1 to 20 carbon atoms, alkenyl containing 2 to 6 carbon atoms, benzyl, halo substituted benzyl, .alpha.-methyl benzyl, furfuryl and pyridyl methyl; R.sub.2 is hydrogen or alkyl containing 1 to 10 carbon atoms; R.sub.3 and R.sub.4 are independently hydrogen or alkyl containing 1 to 4 carbon atoms; and R.sub.5 is divalent alkylene containing 2 to 4 carbon atoms.

Biocidal isothiourea compounds

Insecticidal or miticidal compounds have the formula ##STR1## in which R is selected from the group consisting of 1-4 carbon alkoxy, phenyloxy, and 1-6 carbon alkylthio;
