| Overview | Diptera fast, also known as killing grass fast, benefit farmers, is an organic heterocyclic class of killing and contact herbicide. It can be rapidly absorbed by the plant green tissue, interfering with the photosynthesis of the plant green tissue, producing hydrogen peroxide, and causing the green tissue of the weed to die. But can not penetrate the mature bark, the underground root, stem basically ineffective. Suitable for fruit, Mulberry, tea garden and other non-cultivated land use, control has been the emergence of weeds. It has good effect on Compositae, Cruciferae, Solanaceae and Labiatae, but has poor control effect on Polygonaceae and rosacea. It can also be used as a pre-harvest cumulant for broad-leaved crops. |
