Abstract

The invention discloses a pesticide composition containing dinotefuran. Applied as a water dispersible granule, a suspending agent or a wettable powder, the composition comprises 1%-80% of an active component, 1%-20% of a composite auxiliary agent and the balance of a filling material. Applied as an emulsion in water or a micron emulsion, the composition comprises 1%-40% of the active component, 1%-20% of the composite auxiliary agent, 1%-40% of a solvent, and the balance of water. The active component comprises dinotefuran and an other pesticides in a mass ratio of 1:(0.2-50), wherein the other pesticides is malathion, DDVP, phoxim or fipronil. The pesticide of the present invention has a good insecticidal effect, a long insect control time, a wide insecticidal scope, low costs, does not cause resistance in insects, and is safe for crops and environment-friendly.

Description

technical field [0001] The invention relates to an insecticide for the agricultural field, in particular to an insecticide with dinotefuran as the main active ingredient. Background technique [0002] As people use chemical pesticides at higher concentrations and higher doses, the resistance of pests continues to increase, and environmental pollution is becoming more and more serious; the mixed use of insecticides can expand the insecticidal spectrum, delay the development of pest resistance, and reduce The cost of use has become a technical means commonly used in China. [0003] Neonicotinoid insecticides are a new type of insecticides with high efficiency, safety and high selectivity, and they are developing rapidly in domestic and foreign markets. The research and development of neonicotinoid insecticides has been started in China since the late 1980s, and a lot of progress has been made so far. Dinotefuran is a third-generation neonicotinoid insecticide developed by Mi...
