Oxamyl is a neurotoxic insecticide used on cotton, fruit and vegetable crops (apples, potatoes and tomatoes).

Overview

Oxamyl, a synthetic organic chemical, is a highly toxic white crystalline solid with a slight sulfurous odor. Oxamyl is the chemical ingredient identified in widely used insecticides/nematicides, for example Vydate L. Vydate is a registered trademark of DuPont Inc.

Uses

EPA has classified most products containing oxamyl as restricted use pesticides intended for occupational use only for control of insects, mites and nematodes on field crops, fruits and ornamentals.

Health Effects

Some people who drink water containing oxamyl well in excess of the maximum contaminant level (MCL) for many years could experience slight nervous system effects.

EPA Definitions:

1Maximum Contaminant Level Goal (MCLG) - The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety and are non-enforceable public health goals.

Maximum Contaminant Level (MCL) - The highest level of a contaminant that is allowed in drinking water. MCLs are set as close to MCLGs as feasible using the best available treatment technology and taking cost into consideration. MCLs are enforceable standards.

Maximum Residual Disinfectant Level Goal (MRDLG) - The level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contaminants.

(TT) Treatment Technique - A required process intended to reduce the level of a contaminant in drinking water.

Maximum Residual Disinfectant Level (MRDL) - The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants.

2 Units are in milligrams per liter (mg/L) unless otherwise noted. Milligrams per liter are equivalent to parts per million.
