Acetamiprid Chemical Properties
The new pesticide
Acetamiprid, also known as Mospilan, is a new type of pesticide. It belongs to nitro-methylene heterocyclic compounds. It acts on nicotinic acetylcholine receptors in the insect nervous system synapses, interferes with signal conduction in the insect nervous system, causes neurological pathway blockage, and leads to the accumulation of the neurotransmitter acetylcholine in the synapse. This ultimately results in insect paralysis and death. Acetamiprid has contact and stomach toxicity. In addition, it offers strong penetration, good availability, and long-lasting efficacy.
Acetamiprid can be used to prevent and control aphids, planthoppers, thrips, lepidopteran pests, and other pests on rice, vegetables, fruit, and tea bushes. At a concentration of 50 to 100 mg/L, acetamiprid effectively controls aphids and vegetable aphids, controls peach borer, and can kill eggs.
Physicochemical properties
The original product, acetamiprid, is a white crystalline material. Its content is more than 99%. The melting point is 101–103.3 °C, and the vapor pressure is less than 0.33 × 10-6 Pa (25 °C). Acetamiprid is slightly soluble in water, with a water solubility of 4.2 g/L. It is also soluble in acetone, methanol, ethanol, dichloromethane, chloroform, acetonitrile, and similar solvents. It is stable in neutral to slightly acidic media and can be stored at room temperature for 2 years. Gradual hydrolysis occurs at pH 9 and 45 °C. It is stable in sunlight.
