개요
Oxamyl, is also called N,N-dimethyl-2-methylcarbamoyloxyimino- 2-(methylthio)acetamide (IUPAC), consists of colorless crystals, which are readily soluble in water, methanol, ethanol, acetone, and fairly soluble in toluene. Oxamyl is produced by chlorination of the oxime of methylglycolate, reaction with methanethiol and alkali, and conversion to the carbamate with methyl isocyanate.용도
Oxamyl is a pesticide used in the treatment and protection of crops from parasites and insects.농업용
Insecticide, Nematicide, Acaricide: A systemic and contact insecticide/acaricide and nematicide, oxamyl is a restricted use pesticide used on apples, bananas, carrots, celery, citrus, cotton, cucumbers, eggplants, garlic, ginger, muskmelon (including cantaloupe and honeydew melon), onion (dry bulb), peanuts, pears, peppers, peppermint, pineapples, plantains, potatoes, pumpkins, soybeans, spearmint, squash, sweet potatoes, tobacco, tomatoes, watermelons, yams. Oxamyl is also used on non-bearing apple, cherry, citrus, peach, pear, and tobacco. It is applied directly onto plants or the soilsurface. It is available in both liquid and granular form, but the granular form is banned in the U.S. It has no residential use. Registered for use in EU countries[115상품명

Soil. Oxamyl rapidly degraded in a loamy sand and fine sand soil at 25°C to carbon dioxide and the intermediate methyl N-hydroxy-N,N-dimethyl-1-thiooxaminidate (Rajagopol et al., 1984). The reported half-life in soil is approximately one week (Worthing and Hance, 1991). Ou and Rao (1986) reported a half-life in soil of 8–50 days. The reported half-lives of oxamyl in Pitstone, Devizes, Sutton Veany and Mepal soils at 15°C were reported to be 10.2–13.1, 6.2, 7.1 and 17.8 days, respectively (Bromilow et al., 1980). Smelt et al. (1987) reported that oxamyl degraded at a higher rate in field plots after repeated applications of this nematocide than in soils that received no treatment. The repeated applications of oxamyl to soils probably induced microbial activity, which resulted in the accelerated disappearance of this compound.Harvey and Han (1978) reported a half-life of 8 days for oxamyl in soil.
Groundwater. According to the U.S. EPA (1986) oxamyl has a high potential to leach to groundwater.
Plant. Dislodgable residues of oxamyl on cotton leaf 0, 24, 48, 72 and 96 hours after application (0.41 kg/ha) were 1.5, 1.1, 1.2, 0.85 and 0.76 mg/m2, respectively (Buck et al., 1980).
Chemical/Physical. The hydrolysis half-lives of oxamyl in a sterile 1% ethanol/water solution at 25°C and pH values of 4.5, 6.0, 7.0 and 8.0, were 300, 17, 1.6 and 0.20 weeks, respectively (Chapman and Cole, 1982). Under alkaline conditions, oxam
