Pirimicarb
Pirimicarb
Pirimicarb (pronunciation: /pɪˈrɪmɪkɑːrb/) is a selective insecticide used primarily for the control of aphids. It belongs to the chemical class of carbamate pesticides.
Etymology
The term "Pirimicarb" is derived from its chemical name, 2-dimethylamino-5,6-dimethylpyrimidin-4-yl dimethylcarbamate. The name is a combination of parts of the words 'pyrimidin', 'carbamate', and 'dimethyl', which describe its chemical structure.
Usage
Pirimicarb is used in a variety of agricultural settings, including fruit and vegetable crops, ornamental plants, and cereal crops. It is effective against a wide range of aphid species, and is often used as part of an Integrated Pest Management (IPM) strategy.
Mode of Action
Pirimicarb works by inhibiting the enzyme acetylcholinesterase in the nervous system of aphids. This leads to an accumulation of acetylcholine, causing paralysis and death in the insects.
Safety and Environmental Impact
Pirimicarb is considered to be of low toxicity to humans and other mammals. However, it is highly toxic to bees and other beneficial insects, as well as to aquatic organisms. Therefore, its use should be carefully managed to minimize harm to non-target species.
