to control many insects, primarily aphids, mites, and thrips.
Approximately 150,000 pounds of ODM active ingredient are used annually in the United States.
The resistance mechanisms to oxydemeton-methyl were surveyed in two Iranian strains of the two spotted spider mite, Tetranychus urticae Koch. Bioassay was carried out on two strains, collected from Tehran and Rasht using a dipping method.
The MRLs are expressed as the sum oxydemeton-methyl, demeton-S-methyl, and demeton-Smethylsulphon, expressed as oxydemeton-methyl.
