The invention relates to a novel herbicide synergist and a preparation and use method thereof, belonging to the technical field of plant protection tank-mixing adjuvants. The above-mentioned novel herbicide synergist is prepared from the following components in parts by weight: 10-50 parts by weight of wood vinegar; 5-30 parts by weight of lecithin; 5-30 parts by weight of organic acids; 5-20 parts by weight of surfactant 1-10 parts by weight of solvent; Described lecithin and wood vinegar mass ratio are 1:0.5-5. The present invention adopts wood vinegar liquid as the main raw material, compound lecithin and other synergistic components, can adjust the pH value of the liquid medicine system, and the synergistic effect of wood vinegar liquid, organic acid and lecithin can promote the localization of herbicides in the crop target body, Absorption and conduction have synergistic effects on most herbicides, and the synergistic effect on acid-stable herbicides is more obvious. |
