Novel N-(alpha-haloacyl)-N-hydrocarbyl carbamoyl halides and a process for their preparation are provided. The novel compounds are useful as intermediates in the preparation of insecticides.

N-(alpha-haloacyl)-N-hydrocarbyl carbamoyl halides

Novel phenoxyphenyl and phenoxypyridyl benzoyl ureas and a process for their preparation are provided. The novel ureas are useful as the active toxicant in pesticidal compositions.

Novel pesticidal phenoxyphenyl and phenoxypyridyl benzoyl ureas and

Pesticidal phenoxypyridyl benzoyl ureas

Bis-carbamoyl sulfide compounds exhibit exceptional broad spectrum pesticidal activity and increased residual pesticidal activity, coupled with extremely low phytotoxicity.

Insecticidal bis-carbamate sulfides

Certain N-polyhaloalkanesulfenyl carbamoyloximino di-sulfur containing heterocyclic compounds have exceptional pesticidal properties and low mammalian toxicity.

N-Trihalomethanesulfenyl carbamoyloximino di-sulfur heterocyclic

2-Oximino-tetrahydro-1,4-thiazin-5-one compounds are useful as intermediates in the preparation of 2-carbamoyloximino-tetrahydro-1,4-thiazin-5-one carbamate compounds that exhibit outstanding pesticidal activity.
