Compound herbicide based on dichloro quinolinic acid
The invention discloses a compound herbicide based on quinclorac, which comprises 20 - 30 parts of quinclorac. Dichloromethane 3-8 parts, synergist 10 - 20 parts, wetting agent 1.5 - 4.5 parts, dispersing agent 1-3 parts, defoaming agent 0.5 - 2.5 parts and water 50 - 70 parts. The synergist inhibits the growth of cells by hindering the synthesis of the protein, and the sprouts of monocotyledonous plants are obtained through young buds of plants. The lower endoderm of the dicotyledonous plant is absorbed and conducted upwards, the seeds and roots absorb conduction, the absorption amount is low, the conduction speed is slow, the growth of young buds and roots is inhibited.
