Abstract

The invention provides an insecticidal farm chemical composition and application thereof. The composition adopts one of diafenthiuron or lufenuron, and indoxacarb as active components. The composition has the advantages that: (1) compared with a mono agent, the composition has obvious synergism to lepidoptera pests and improves the control effect; (2) the action mechanisms of the active components and the conventional insecticides of organic phosphorus, pyrethroid and the like are different without cross resistance, and are different from using more methylamino avermectin benzoate, so that the field drug dosage is reduced greatly and the cost is reduced; (3) the difference of the action mechanisms of the active components in the composition is advantageous to overcome and retard the generation of pest drug resistance; and (4) the composition enlarges the controlling spectrum, and has double effects on treating various pests appearing simultaneously.

Description

technical field [0001] The invention relates to an insecticidal pesticide composition and application thereof, which are used for preventing and controlling pests and mites in agriculture. Background technique [0002] In the actual process of agricultural production, chemical control is the main effective means of pest control. However, in recent years, due to single and unscientific drug use, many kinds of pests have developed resistance to the currently used pesticides, such as diamondback moth, beet armyworm, cotton bollworm, etc. Resistance to pesticides is very common and has become a major problem in chemical control . Due to the resistance of pests, frequent application of pesticides has caused increased burden on farmers and increased environmental pollution. Therefore, in pest resistance management and integrated control systems, there is an urgent need for insecticides with high efficiency, low toxicity, low residue, and novel action mechanisms. [0003] Indoxa...
