Bentazone is an organic chemical for use in herbicides. It is categorized under the thiadiazine group of chemicals. It is also called Bentazon, Basagran, Herbatox, Leader, or Laddock.
Function
Bentazone is a selective herbicide as it only damages plants unable to metabolize the chemical. It is considered safe for use on alfalfa, beans (with the exception of garbanzo beans), corn, peanuts, peas (with the exception of black-eyed peas), pepper, peppermint, rice, sorghum, soybeans and spearmint; as well as lawns and turf.

1. Hand Protection
PVC or other plastic material gloves
2. Respiratory Protection

Note
1. In general, bentazone is quickly metabolized and degraded by both plants and animals. However, soil leaching and runoff is a major concern in terms of water contamination.
2. A number of limits have been placed on the chemical for farming use to reduce the possibility of toxic effects on humans.
3. This farm chemical is considered toxic to birds as it affects their reproductive capacities.
4. Among mammals, it is found to be moderately toxic when ingested or absorbed through the skin.
