Abstract

The invention relates to a water suspension pesticide containing pymetrozine and fenobucarb and a preparation method thereof. The rate of the pymetrozine to the fenobucarb is 1:0.5 to 1:8, and the pymetrozine and the fenobucarb account for 8% to 40% of the proportion by weight in the formula in total. The water suspension pesticide also comprises 1% to 10% of dispersing agent, 0.5% to 5% of wetting agent, 0.1% to 1% of thickener and suspension stabilizer, 1% to 5% of freeze proof agent, 0.1% to 1% of defoamer and the balance of water and is prepared in the following steps of filling the measured pymetrozine, fenobucarb, dispersing agent, wetting agent, freeze proof agent and water into a reaction kettle; cutting for 10 to 40 minutes; grinding for two to four times by adding the measured defoamer; adding the measured thicker, and cutting for 10 to 30 minutes. The pesticide of the invention overcomes the defects of weak pest defeat performance by independently using the pymetrozine and short effect time of the fenobucarb, and has the advantages of low cost, good effects for killing brown plant-hoppers and striped rice borers, no powder dust flying and no environment pollution.

Description

technical field [0001] The invention relates to a pesticide composition and a preparation method thereof, in particular to a water-suspended pesticide pesticide containing pymetrozine and secbucarb and a preparation method thereof. Background technique [0002] Pymetrozine and Zhongbucarb are two commonly used insecticides. [0003] Pymetrozine: 4,5 dihydro-6-methyl-4-(3-pyridinylamino)-1,2,4-3(2H)-one. [0004] Its physical and chemical properties: the pure product is a colorless crystal, melting point 217°C, density 1.36 (20°C), solubility (g / L); water 0.29 (25°C), ethanol 2.25 (20°C), stability: at pH = The DT50 of hydrolysis at 1 hour is 4.3 days, and the DT50 of hydrolysis at pH=5 is 25 days. [0005] Object of action: Pymetrozine is a new type of non-destructive insecticide. Its preparations can be used to control most of the Homoptera pests, especially the pests of Aphididae, Whiteflyidae, Leafhoppers and Planthoppers. It is suitable for vegetables, ornamental Plan...
