Usage

Uses

Used in Agriculture:
Isoprocarb is used as an insecticide for the control of rice, cacao, sugarcane, and vegetable pests. It effectively controls leafhoppers, plant hoppers, and aphids on a variety of crops. Its residual activity provides long-lasting pest control.
Isoprocarb is used as a contact and stomach poison for insects, as it acts by inhibiting cholinesterase, which is essential for the proper functioning of the nervous system in insects. This inhibition leads to the death of the pests, thus protecting the crops from damage.

Safety Profile

Poison by ingestion, intravenous, and intraperitoneal routes. Moderately toxic by skin contact. When heated to decomposition it emits toxic fumes of NOx. See also CARBAMATES. Used for controlling leafhoppers, planthoppers, and bugs in rice and cacao.

Toxicology

The insecticide isoprocarb is a Class II toxin (moderately hazardous), with the acute oral LD50 among rats being 403-485mg/kg, while the percutaneous LD50 among male rats and mice is>500mg. It is a PAN Bad Actor chemical, since it is a cholinesterase inhibitor. Symptoms of poisoning with this insecticide include muscle weakness,dizziness,salivation,nausea,vomiting,sweating,headache,effects on the CNS and depression. PPE such as splash-resistant safety goggles and chemicalresistant clothing, gloves and masks are advised.

SYSTEM FOR PROTECTING GOODS DURING TRANSPORT

A system for protecting stored goods in a container (10), comprises a cage-like structure (20) formed by at least one pesticide treated net (22), capable of enclosing the stored goods, wherein the cage like structure (20), further comprises means for suspending the pesticide treated nets (14, 28, 30, 32, 34), and means for opening and closing the cage-like structure (26) on at least one section (24) of the at least one net (22). The system is particularly useful for the transport of tobacco, coffee, dried fruits, cocoa, nuts, tea, cereals, vegetables, spices and animals.

INSECTICIDAL CARBAMATES EXHIBITING SPECIES-SELECTIVE INHIBITION OF ACETYLCHOLINESTERASE (AChE)

The present invention includes insecticidal carbamates that are useful, for example, for the control of insects, such as mosquitoes, which can be used in applications where exposure to and/or contact with humans is likely. The insecticides of the present invention include phenyl N-methyl carbamates and compositions comprising them that exhibit species-selective inhibition of acetylcholinesterase (AChE) and are preferably toxic to mosquitoes but not humans. Of particular interest are compounds of Formula (I) and Formula (II): Compounds of Formula (I) and Formula (II) are especially suitable for insecticide treated nets and indoor residual spraying for mosquito control.

One-pot, three-step preparation of alkyl and aryl alkylcarbamates from S-methyl N-alkylthiocarbamates

A general procedure for the synthesis of alkyl and aryl alkylcarbamates starting from the corresponding 5-methyl N-alkylthiocarbamates is described. This procedure consists of three steps that are carried out in a one-pot fashion, without isolating the intermediate N-alkylcarbamoyl chlorides or alkyl isocyanates. All the target products were obtained in high yields (16 examples, average yield 91%). To be noted is the recovery of a co-product of industrial interest, dimethyl disulfide, in a half mole amount for each mole of thiocarbamate, with complete exploitation of the reagent. The alkyl isocyanates, if required, can also be isolated in high yields. Georg Thieme Verlag Stuttgart.

Soluble polymer based matrix for chemically active water insoluble components

This invention relates to a water soluble matrix composition comprising an anionic surfactant, a C6 to C18 alkyl pyrrolidone, urea and a water insoluble copolymer of vinyl pyrrolidone with not more than 50 wt. % of a comonomer selected from the group of an α-olefin, vinyl acetate, an acrylic or methacrylic acid ester and methacrylamide as a free flowing particulate solid which matrix is suitably mixed with a water insoluble, chemically active component, such as an agrochemical, to provide a clear sprayable film forming emulsion, such as a non-leachable film on a plant or other substrate surface. The invention also relates to the method of preparing the matrix and to the incorporation of an agrochemical concentrate and plant spray composition.

Process for making alkyl N-alkyl or N-aryl-thiocarbamates

A process for the preparation of alkyl esters of N-alkyl or N-aryl thiocarbamic acid having the formula: STR1 wherein R is alkyl or aryl, R2 is alkyl and R1 is hydrogen or alkyl which comprises reacting the S-alkyl ester of N-alkyl or aryl dithiocarbamic acid having the formula: STR2 wherein R, R1, R2 have the meanings stated above with an appropriate alkali metal alkoxide in the presence of one or more alcoholic solvents.

Process for the preparation of aryl esters of N-alkyl carbamic acids

Aryl esters of N-alkyl carbamic acids are prepared by reacting an alkyl N-alkyl carbamate of the general formula R1 - NH - COO - R3 wherein R1 and R3 are both alkyl groups with a substituted phenol in the presence of a halogen-containing phosphorus compound to produce the desired ester of the formula R1 -NH - COOR2 wherein R1 is an alkyl group and R2 is an aryl group.

Process for the preparation of aryl esters of N-alkyl carbamic acids

The invention relates to a process for the preparation of aryl esters of N-alkyl carbamic acids. The process comprises reacting an alkyl N-alkyl carbamate of the general formula: wherein R1 and R3 are both alkyl groups, with a substituted phenol in the presence of a halogen-containing phosphorous compound to produce an aryl ester of N-alkyl carbamic acid having the general formula: wherein R1 is an alkyl group and R2 is an aryl group derived from the substituted phenol. In a preferred embodiment of the invention, the process is used for the preparation of aryl esters of N-methyl carbamic acid.
