Problems solved by technology

However, due to their widespread use as individual insecticides, pests have developed some resistance to these single agents
The insecticidal mechanism of thiacloprid is different from that of traditional insecticides. It mainly acts on the post-junction membrane of insect nerves. By binding to nicotinic acetylcholine receptors, it interferes with the normal conduction of the insect nervous system, causing blockage of nerve channels, resulting in acetylcholine Therefore, it can be used for resistance management. The disadvantage of tefluthrin is that it only has a killing effect on pests in the soil, and its insecticidal effect relatively low

Abstract

The invention discloses a thiacloprid and tefluthrin insecticidal active substance combination, which comprises the following raw materials by weight: 6.5-9.5% of thiacloprid, 1-3.5% of tefluthrin, 6-8% of sodium lignosulfonate, 1-3% of butyl naphthalene sulfonate, 3-6% of epoxidized soybean oil, 9-13% of film-forming agent and the balance of kaolin. The thiacloprid and tefluthrin insecticidal active substance combination can be taken as an active component to form a new insecticide for preventing the drug resistance of the insect pests and enhancing the insecticidal effects.

Description

technical field [0001] The invention relates to pesticides, which is a combination of thiacloprid and tefluthrin insecticidal active substances. Background technique [0002] Thiacloprid is a nitromethylene systemic insecticide, and it is an effective agent for controlling piercing-sucking and chewing mouthparts pests. Tefluthrin is a soil insecticide, which is mainly used to control Coleoptera and Lepidoptera, Diptera, Squash Twelve Star Beetle, Needleworm, Flea Beetle, Scarab, Stevia Cymbidium, Swedish Soil pests such as straw flies. But since they are widely used as single insecticides respectively, pests have acquired some resistance to these single agents. The insecticidal mechanism of thiacloprid is different from that of traditional insecticides. It mainly acts on the post-junction membrane of insect nerves. By binding to nicotinic acetylcholine receptors, it interferes with the normal conduction of the insect nervous system, causing blockage of nerve channels, res...
