The invention discloses a weeding suspending agent. The weeding suspending agent is characterized by comprising the following components in percentage by weight: 25-45 percent of
dithiopyr, 40-70 percent of water, 1.5-2.5 percent of cosolvent, 1-3 percent of
wetting agent, 1.5-3.5 percent of dispersing agent, 0.5-1 percent of defoaming agent, 1-2 percent of
thickening agent and 0.5-1 percent of
preservative. The weeding suspending agent has the advantages that water is used as a
solvent, so that no dust drifts in application, the
grinding particle size is small, which is convenient for plants to absorb, environmental
pollution is reduced, and the safety of transportation and storage is improved; and the weeding suspending agent confirms to the requirement of green agricultural production and has the effects of good stability, freeze proofing, anticorrosion and good weeding effect.
