Application of Diflufenican
Apr 09, 2018

Is a carotenoid biosynthesis inhibitor, is a broad-spectrum, selective wheat field herbicide that causes chlorophyll damage and cell rupture, plant death. 125 ~ 250g/ha pre-emergence or post-emergence application in autumn sowing wheat and barley fields to control grasses and broad-leaved weeds, especially pigweed, Veronica and amaranth weeds. The agent has the following characteristics: broad spectrum of weed killing; control of weedy weeds; longevity of Chinese medicine in soil; stable effect; it can be mixed with other herbicides. After the application of pesticides, a layer of anti-leaching drug layer is formed on the soil surface and remains live during the whole growth period of the crop. When the weeds germinate through this layer of pesticide, they contact and absorb the pesticide, and the roots of the weeds are exposed. To medicine soil, it can also be absorbed. Whether the effect of the drug can be exerted depends on whether the drug can evenly cover the surface. After weed seeds on the soil surface or close to the soil surface are germinated, the agent is absorbed through both shoot and root systems. When the medicament is passed upwards, the buds are decolorized or whitened, and finally the whole plant wilts and dies. The agent severely inhibits the biosynthesis of carotenoids and causes decolorization of the plants and indirectly destroys photosynthesis. The speed of use is directly related to the intensity of light. The old plant tissues will eventually suffer death due to the inhibition of photosynthesis of new leaves. It can be used before or after weed buds. On the contrary, some of the genera of Umbelliferae (carrots) and Asteraceae are almost ineffective. In short, it can prevent most of the annual broad-leaved weeds, and it is also effective against cedar grasses. If used in combination with other suitable grass herbicides, the herbicide spectrum can be expanded.
