Abstract
The invention discloses a special post-emergence compound herbicide for codonopsis pilosula. The herbicide is prepared from the following raw materials in percentage by weight: 6-7% of quizalofop-p-ethyl, 20-23% of 2.4-D butyl ester, 4-6% of an emulsifier, 3-5% of a dispersant, 1-3% of a thickener and 57-60% of plant oil. The special post-emergence compound herbicide for codonopsis pilosula disclosed by the invention is high in herbicidal activity, can effectively prevent and eliminate post-emergence weeds in a codonopsis pilosula field, particularly has a remarkable preventing effect on various gramineous, and almost broadleaf weeds in the codonopsis pilosula field and can achieve a purpose of universally eliminating monocotyledonous and dicotyledonous weeds. The quizalofop-p-ethyl and the 2.4-D butyl ester are complementary in action and none of the two is dispensable. The two generate synergistic interaction action, so that the herbicidal activity of the herbicide is greatly improved. The emulsifier enables the quizalofop-p-ethyl and the 2.4-D butyl ester to be dispersed in water by form of micro-liquid globules (the liquid globules are 1-50 microns) to become a relatively stable emulsion. Meanwhile, both the quizalofop-p-ethyl and the 2.4-D butyl ester are mixed for leaf surface treatment, so that the herbicide is wide in weeding spectrum and the lasting period of the agent is relatively long.
