The ground herbicide is also called the soil treatment agent. Before the weeds are sprayed, the herbicide is sprayed with the herbicide, and a layer of film is formed on the surface. When the weeds are unearthed through the toxic soil layer, the weed coat of the weeds Or the radicle root sheath absorbs the herbicide and is poisoned and killed. It is blocked in the soil. This herbicide is safe for corn seedlings, and corn can be safely emerged because there is an enzyme in the corn body - ketone can decompose the toxin of the herbicide. Therefore, the corn can be okay to emerge, and the weeds cannot be unearthed normally, thus serving the purpose of blocking weeding.
Tips for use: First, the grass is used before it is used. After the emergence of the grass, it will not work. (The corn does not matter.) Second, the sensation is good, the surface is wet, the grass seeds will germinate early, cross the toxic soil layer early, poisoning death. . The herbicide is valid for 25-30 days. The third is to spray more water, enough water (more than 2 barrels), to spray evenly; fourth is to use the medicine in the evening, make full use of the "water" to moisturize the film.
