Chlortoluron

Chlortoluron is a herbicide that is used to control weeds in cereal crops. It is a member of the phenylurea class of herbicides, which also includes diuron, linuron, and isoproturon. Chlortoluron is used primarily in the agricultural industry, but it can also be found in some pesticide products for home and garden use.

Chemical Properties

Chlortoluron is a white, crystalline solid with a slight, characteristic odor. It is slightly soluble in water and moderately soluble in most organic solvents. The chemical formula for chlortoluron is C10H13ClN2O.

Mode of Action

Chlortoluron works by inhibiting the process of photosynthesis in plants. It specifically targets the enzymes involved in the synthesis of amino acids that are essential for plant growth. This disruption of the plant's metabolic processes leads to its death.

Environmental Impact

Chlortoluron is considered to be moderately toxic to aquatic life. It can also persist in the soil for several months, potentially affecting non-target plants and wildlife. However, it is not considered to be a significant risk to human health.

Regulation

In the European Union, chlortoluron has been classified as a priority substance under the Water Framework Directive. This means that its levels in surface waters are monitored and controlled. In the United States, chlortoluron is regulated by the Environmental Protection Agency (EPA).
