Mechanism of action of dioxin
The action mechanism of dioxin pine is that after absorbing chemicals, the plant can inhibit the synthesis of diterpenes in sensitive plants, hinder the biosynthesis of carotene and chlorophyll, cause chlorosis and whitening of leaves, and make weeds die in a short period of time; even if the seeds that absorb chemicals can sprout and emerge, they will die in a short time because of lack of pigment. At present, it is mainly used to control annual Gramineae weeds and broadleaf weeds.
What are the characteristics of clenbuterol?
The main results are as follows: 1. Broad spectrum of herbicide and high activity. Dioxin pine can be used in soybean, rice, rape, cotton, cassava, sugar cane and tobacco fields to control annual grasses and broad-leaved weeds such as barnyardgrass, dogtail grass, horse tang, sage, purslane, quinoa, duckweed, Solanum nigrum, Xanthium sibiricum, ragweed and so on. It also has a strong inhibitory effect on Rabdosia angustifolia, thistle, borage, bauhinia and so on. At present, it is considered that clenbuterol is one of the better agents to control the "three dishes" (orchid, borage, thorn).
2. It lasts for a long time. Generally, when the drug is used at one time, the efficacy can maintain the whole growth period of the crop, and it can also play a good effect under the conditions of drought and low temperature.
3. The time of medication is more flexible. It can be used for pre-bud use and pre-planting closure treatment, as well as post-bud stem and leaf treatment.
4. Low toxicity. It is safe for crops and human, animal and aquatic organisms, and is friendly to the environment.
5. Strong compatibility. There are many kinds of herbicides that can be mixed, so there are many compound products, easy to use and high efficacy.
The above is the relevant introduction of the action mechanism of dioxin, and I hope it will be helpful to everyone.
