Abstract: The insecticide carbofuran (2,3-dihydro-2,2-dimethyl-7-benzofuranyl methylcarbamate) is combined with an organophosphorus additive of the formula ##STR1## in which R.sup.1 is C.sub.1 -C.sub.4 alkyl,R.sup.2 is C.sub.1 -C.sub.4 alkyl,R.sup.3 is C.sub.1 -C.sub.4 alkylene,X is oxygen or sulfur, andn is zero or one,for application to soil where previous applications of carbofuran have resulted in successive decreases in the insecticidal activity of carbofuran. The lost activity of the carbofuran is thereby restored.

Abstract: This application is directed to novel compounds useful as insect repellents. The compounds of this invention have the following generic formula: ##STR1## wherein R is selected from the group consisting of hydrogen, alkyl, alkoxyalkyl, alkenyl, and cyanoalkyl; R.sub.1 is selected from the group consisting of alkyl, alkenyl, haloalkenyl, cycloalkenyl, alkoxyalkyl, and furfuryl; R and R.sub.1 taken together can form a ring structure selected from alkylene, alkyl substituted alkylene, alkenylene and alkyl substituted alkenylene.

Abstract: This invention relates to insecticidal active compositions. More specifically, this invention relates to the use of O,O'-dipropargyl chloromethylphosphonate as a synergist for a commercially available insecticidal active compound defined as O,O-dimethyl-O-(2-methoxy-4-cyanophenyl)-phosphorothioate.

Abstract: The combination of insecticidal active compounds with an ultraviolet light stabilizer is described herein. The insecticidal active compounds have the following generic formula: ##SPC1##In which R and R.sup.1 are independently methyl or ethyl; n is the integer zero or one; R.sup.2 is hydrogen, lower alkyl, lower alkenyl, lower alkoxy, halogen, nitro, lower alkylthio, or certain heterocyclic radicals. The ultraviolet stabilizers have the formula: ##SPC2##Wherein R.sub.3 and R.sub.4 can be the same or different and can be selected from the group consisting of hydrogen, lower alkyl, lower alkoxy, lower carboalkoxy, cyclohexyl, phenyl and halogen. These stabilizers substantially enhance the useful life of the insecticidally active compounds.
