The mass ratio of the said propyzamide: amino acid is 100:0.1-100:1000, and the mass percentage of the total mass of the propyzamide + amino acid in the compound preparation is 5-80%. Compared with the prior art, the synergistic propyzamide compound preparation of the invention has the advantages that the biological activity of 0 weeding can be significantly improved, the usage amount is reduced, and the cost and environmental pollution are reduced compared with the single use.
