Abstract

The invention discloses a pesticide combination for preventing and controlling the Psylla chinensis Yang et Li and a preparation method thereof. The pesticide combination comprises the following raw materials in percent by weight: 1-25 percent of Paichongding and 1-25 percent of spirotetramat. The pesticide combination is prepared through the addition of an emulgator, a cosolvent, an antifreezing agent, a defoamer, a thickener, a stabilizer, a PH regulator, water and the like, has a synergistic interaction effect in the insecticidal efficacy, and can prevent and control the Psylla chinensis Yang et Li, the aleyrodidae and the like, is outstanding in effect, and is safe and environmental-friendly.

Description

technical field [0001] The invention relates to the technical field of pesticide preparations, in particular to a pesticide composition for controlling pear psyllid and a preparation method thereof. Background technique [0002] Pichamid is a new type of high-efficiency, broad-spectrum, and low-toxicity neonicotinoid insecticide, which is mainly used to control Homoptera pests, and has a good control effect on rice planthoppers. Chemical name: 1-((6-chloropyridin-3-yl)methyl)-5-propoxy-7-methyl-8-nitro-1,2,3,5,6,7-hexahydro imidazo[1,2-a]pyridine. Molecular formula: C17H23CIN4O3. Molecular Structure: [0003] [0004] Spirotetramat is a new type of tetron acid insecticide. The appearance of pure product is light beige powder without special smell; decomposition temperature is 235°C; melting point: 142°C; vapor pressure (25°C): 1.5×10-8Pa; solubility (20°C): 33.4mg / L in water (pH6. 0-6.3), in organic solvents (g / L): 0.055 in n-hexane, 44 in ethanol, 60 in toluene, 67...
