Acetamiprid Powder Usage and Synthesis:

Acetamiprid is a new type of insecticide, which is a nitro methylene heterocyclic compound, and acts on the nicotinic acetylcholine receptors at the synapses of the insect nervous system. It acts on nicotinic acetylcholine receptors at the synapses of the insect nervous system, interfering with the transmission of stimuli in the insect nervous system. Action The nicotinic acetylcholine receptors at the synaptic sites of the insect nervous system interfere with the transmission of stimuli in the insect nervous system, causing blockage of the nervous system pathways and resulting in neurotransmitters. Acetyl The accumulation of acetylcholine at synaptic sites leads to paralysis and eventual death of insects. Acetamiprid can be used to control aphids, lice, thrips and lepidoptera in rice, vegetables, fruit trees and tea trees. and lepidopteran pests. At a concentration of 50-100 mg/L, it can effectively control cotton aphid, vegetable aphid, peach psyllid, etc., and kill eggs.

Pharmacokinetics of Acetamiprid Powder:

Synthesis of Acetamiprid In a 250 mL reaction flask, add 20.5 g (85.27%) of N-cyano-N'-(2-chloro-5-pyridinylmethyl)acetamidine, 54.5 mL of chloroform, and 0.11 g of methylbutylammonium bromide. Add 11.6g of dimethyl sulfate and 8.4g of 50% aqueous NaOH solution dropwise at 15°C with stirring for 3h. Add 33.6mL of water Add 33.6mL of water and 0.33g of 40% aqueous dimethylamine solution, stir for 1h at room temperature, separate the layers, extract the aqueous layer with chloroform, and combine the chloroform layers. Add 38mL of water and distill at atmospheric pressure to remove chloroform. Cool Add methanol, then cool to 35℃. Add 37mL of water dropwise and precipitate the solid. Cool until the precipitation is complete. Filter, get a light yellow solid, dry to get 17g of product, crude product with The crude product was recrystallized from aqueous methanol to obtain white needle-like crystals. m.p. 101-103℃. No mutagenic effect in animal test. The product is low toxic to human and animal, and has little killing effect on natural enemies. Aminopyralid is suitable for the control of homopterous pests on fruit trees and vegetables; it can be used as soil treatment with granules to control underground pests.

Clinical Application of Acetamiprid Powder:

Acetamiprid is a chloronicotinoid insecticide. It is characterized by broad insecticidal spectrum, high activity, low dosage, long lasting effect and rapid effect, with touch and stomach poisoning effect. It has a wide spectrum of insecticides, high activity, long duration of action and fast-acting. It is effective against Hemiptera (aphids, leafhoppers, mealybugs, mealybugs, etc.), Lepidoptera (cabbage moths, subterranean moths, small heart-eating insects, longitudinal leaf borers, etc.), and Sphingidae (aspergillus, etc.). ), Sphingidae (Aphids, leafhoppers, mealybugs, mealybugs, moths, etc.), and generalist pests (thrips) are effective. Since the mechanism of action of acetamiprid is different from that of currently used insecticides, it is effective against organophosphorus and carbamate pests. It is effective against organophosphorus, carbamate and pyrethroid resistant pests. It belongs to the same series as imidacloprid, but its insecticidal spectrum is wider than imidacloprid, mainly on cucumber, apple, citrus and tobacco. It has better control effect on aphids on cucumber, apple, citrus and tobacco. Due to the unique mechanism of action of acetamiprid, it is resistant to organophosphorus, carbamate, and pyrethroids. It has a better effect on pests that are resistant to pesticide species such as pyrethroids.
