Thiocarbamates are prepared by a process comprising reacting an aqueous solution of a thiocarbamate salt with an organic halide in the presence of a catalytic amount of a quaternary ammonium salt having the formula
in which R4 and R5 are independently selected from the group consisting of C1-C25 alkyl and C2-C25 alkenyl, R6 and R7 are independently selected from the group consisting of C6-C25 alkyl and C6-C25 alkenyl, and Y- is an anion selected from the group consisting of chloride and bromide; and separating the thiocarbamate from the aqueous solution.

A method of controlling the plant back interval after application of sodium azide. The plant back interval can be significantly shortened by application of a dithiocarbamate, a thiocarbamate, a carbamate, an organic sulfide, an organic disulfide, or an aldehyde, with which the sodium azide may react and become inactivated. These compounds may be applied to soil to deactivate sodium or potassium azide residues and thus allow for immediate planting of a desirable turf or crop, and prevent plant stunting and delayed fruiting of crops without adversely affecting plant growth. The present invention thus provides a method for manipulating the activity period of sodium azide against pests by stopping its activity, when desired, by the application of one or more of these deactivating compounds. The preferred compound is metam sodium which is a dithiocarbamate.
