Metolcarb

Metolcarb is a pesticide that belongs to the category of carbamate pesticides. It is primarily used in the control of pests in a variety of crops, including fruit trees, vegetables, and ornamental plants.

Chemistry

Metolcarb is a carbamate ester and is chemically known as 3,3-dimethyl-1-methoxycarbonyl-2-butene. It is a white crystalline solid with a slight odour. It is soluble in most organic solvents but is slightly soluble in water.

Mode of Action

Metolcarb works by inhibiting the action of the enzyme acetylcholinesterase in the nervous system of insects. This leads to an accumulation of acetylcholine, causing continuous nerve impulses, paralysis, and eventually death of the insect.

Usage

Metolcarb is used to control a wide range of pests, including aphids, mites, whiteflies, and caterpillars. It is applied as a foliar spray and can be used on a variety of crops, including fruit trees, vegetables, and ornamental plants.

Toxicity

Like other carbamate pesticides, metolcarb is toxic to humans and animals if ingested, inhaled, or absorbed through the skin. It can cause symptoms such as nausea, vomiting, abdominal pain, and in severe cases, seizures and respiratory failure.

Environmental Impact

Metolcarb is moderately persistent in the environment and can contaminate soil and water bodies. It is toxic to aquatic organisms and can have a negative impact on non-target species.

Regulation

In many countries, the use of metolcarb is regulated due to its potential health and environmental risks. Users are required to follow safety guidelines and precautions to minimize exposure and environmental contamination.
