Problems solved by technology

However, neonicotinoid active substances also have some defects: the insecticidal spectrum is not wide, and the risk of increased resistance is high (Han Xiaoli. Research progress on pest resistance to neonicotinoid insecticides, "Journal of North China Agricultural Science", 2007, S1 )

Abstract

The invention discloses a synergistic insecticidal composition. The invention relates to the insecticidal composition, the composition contains tolfenpyrad and at least one known active substance which belongs to neonicotinoids, and the invention further relates to an application of the composition in pests of crops.

Description

technical field [0001] The invention relates to a pesticide composition and application thereof, in particular to a pesticide composition containing tolfenpyrad. Background technique [0002] Neonicotinoids are a class of high-efficiency insecticides, and their mechanism of action is to act on nicotinic acetylcholine receptors, interfering with the normal conduction of the insect nervous system, resulting in paralysis and death of insects. Common neonicotinoid active substances include: imidacloprid, acetamiprid, nitenpyram, thiamethoxam, clothianidin, thiacloprid, dinotefuran, chlorothiaprid, nithiazine, and piperacrid. Neonicotinoid active substances have low toxicity to mammals, are environmentally safe, and have high insecticidal activity. However, neonicotinoid active substances also have some defects: the insecticidal spectrum is not wide, and the risk of increased resistance is high (Han Xiaoli. Research progress on pest resistance to neonicotinoid insecticides, "Jou...
