Abstract

The invention belongs to the field of pesticides, and particularly relates to a suspending agent containing pyraclostrobin and difenoconazole and a preparation method of the suspending agent. The suspending agent comprises, in percentage by mass, 0-40% of a pyraclostrobin original, 0-40% of a difenoconazole orignal, 5%-8% of a polycarboxylate dispersing agent DSC2006, 1%-4% of a modified polyether wetting agent W2006, 1%-6% of a thickening agent, 0.1%-2% of a defoaming agent, 1%-6% of an anti-freezing agent and the balance of water.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a suspension containing pyraclostrobin and difenoconazole and a preparation method thereof. Background technique [0002] Pyraclostrobin, also known as pyraclostrobin, is a broad-spectrum fungicide of methyl methoxyacrylate with a pyrazole structure discovered by BASF in 1993. The chemical name is N-methoxy-N-2 -[(N-p-Chlorophenyl)-3-pyrazolyloxymethyl]phenylcarbamate. The pure product is white to light beige odorless crystal, melting point 63.7~65.2℃, vapor pressure (20-25℃): 2.6×10 -8 Pa, solubility (20°C, g / 100mL): distilled water 0.00019, n-heptane 0.37, methanol 10, acetonitrile ≥ 50, toluene, dichloromethane ≥ 57, acetone, ethyl acetate ≥ 65, n-octanol 2.4, DMF43; Octanol / water partition coefficient: logPow4.18 (pH6.5). Pyraclostrobin has a strong inhibitory effect on spore germination and the growth of mycelia in leaves, and has protective and therapeutic activities. Possesse...
