Usage

Uses

Used in Agriculture:
MPMC is used as an insecticide for controlling hoppers and other sucking pests on rice, as well as leafhoppers, planthoppers, and scale insects on fruit. Its non-systemic nature allows for targeted pest control without affecting the overall plant system, making it a valuable tool in integrated pest management strategies.

Metabolic pathway

In plants and animals, the principal pathways of xylylcarb metabolism are oxidation of the 4-methyl substituent, hydroxylation of the N-methyl group, hydrolysis of the carbamate ester to form phenols and conjugation.

Degradation

Xylylcarb is hydrolysed in alkaline conditions (PM).

Process for the production of N-methylcarbamates

Process for the production of N-methylcarbamates: STR1 (wherein RO- is the radical of a substituted phenol or of a naphthol), wherein: in a first reaction step methylamine and diphenyl carbonate are reacted with each other, operating in the liquid phase and as a continuous process, in order to form phenol and phenyl-N-methylurethane; in a second reaction step phenyl-N-methylurethane, within the related reaction mixture outcoming from the first step, is thermally continuously decomposed, to yield a gaseous stream containing methyl isocyanate, from which the components different than methyl isocyanate are condensed off; in a third step the methyl isocyanate stream, outcoming from the second step, after an optional preliminary condensation, is continuously fed and contacted with a solution of a substituted phenol or of a naphthol in an inert organic solvent, containing a basic catalyst, to form N-methylcarbamate (I); N-methylcarbamate (I) is finally recovered from the reaction mixture outcoming from the third step.

Insecticidal and/or acaricidal composition exhibiting low toxicity to mammals and fish

The present invention relates to insecticidal compositions of low toxicity to fishes and mammals characterized by containing m-(p-bromophenoxy)-α-cyanobenzyl trans- or trans-rich-2,2-dimethyl-3-(2,2-dichlorovinyl)cyclopropanecarboxylate of the formula (I), STR1 and a carbamic ester of the formula (III), STR2 wherein R is a group of the formula, STR3 in which X is a C1 -C4 alkyl or C1 -C4 alkoxyl group and n is 1 or 2, in a ratio of 1 to 1-100 (part by weight) of the former to the latter, and insecticides obtained by mixing said compositions with a carrier or a diluent and if necessary an additive. The term "trans-rich" shows the ratio of trans/cis is not less than 75/25.

Preparation of carbamates

Carbamates are prepared in one step by reacting an alcohol, phosgene, and an amine in the absence of an acid scavenger.
