Imidacloprid is a nitromethylene systemic insecticide, belonging to the chlorinated nicotinyl insecticide, also known as a neonicotinoid insecticide, with the chemical formula C9H10ClN5O2. It has broad-spectrum, high efficiency, low toxicity and low residue, and it is not easy for pests to develop resistance. It can interfere with the normal motor nervous system of pests, make the transmission of chemical signals fail, and cause paralysis and death of pests.
The product has a good quick-acting effect, and has a high preventive effect one day after the drug, and the residual period is as long as 25 days. Mainly used to control piercing-sucking pests.
For the control of piercing-sucking pests and their resistant strains. Has the following characteristics:
(1) Broad-spectrum, high-efficiency and long-lasting effect. It has a very good control effect on aphids, leafhoppers and other pests of piercing-sucking mouthparts and coleopteran pests. It can also be used to control termites in buildings and fleas on pets such as cats and dogs. Generally, 1-2 grams of active ingredients can be used per mu to obtain satisfactory control effects, and the effective period can last for several weeks. One application can protect some crops from pests throughout the growing season.
(2) It is more suitable for treating soil and seeds. It has stomach poisoning and contact killing effects on pests. Treating soil or seeds with imidacloprid, due to its good systemic properties, the metabolites after being absorbed by plant roots and entering plants have higher insecticidal activity, that is, imidacloprid and its metabolites jointly play an insecticidal effect, so the control effect is more effective. high. Imidacloprid can also be mixed with fungicides when used for seed treatment.
(3) The mechanism of insecticidal action is unique. It is a nerve agent, and its target is the nicotinic acid acetylcholinesterase receptor in the post-synaptic membrane of the pest’s nervous system, which interferes with the normal stimulation of the pest’s motor nervous system, resulting in paralysis and death. This is different from the general traditional insecticides. Therefore, for pests that are resistant to organophosphorus, carbamate, and pyrethroid insecticides, imidacloprid still has a better control effect. It has obvious synergy when used or mixed with these three types of pesticides.
(4) It is easy to cause pests to develop drug resistance. Due to its single action site, pests are prone to develop resistance to it. The frequency of application should be controlled during use. It is strictly forbidden to use it twice in a row on the same crop. Other types of pesticides.
