Recently, Xiaobian encountered a strange thing. I want to share it with you today. I hope to transfer it to more farmers. When I pass by a corn field, I found that the corn seedlings have been "smashed" by the same brush. Is it the latest corn high-yield technology in the legend? After all, we found the uncle who is "beheading" the corn in the field and understand the reason. The uncle said a word, subverting my understanding of plant protection in the past few years, the uncle said, "I am ridding the corn to remedy it!" What? I solved the drug, this way I heard it for the first time.
It turned out that the uncle added 2,4-D butyl ester when spraying corn to seal the herbicide, causing leaching phytotoxicity, and encountered high temperature weather when spraying herbicides on corn seedlings, further aggravating the phytotoxicity. .
When we asked the uncle who directed you to deal with this, the uncle said something that shocked me: "This year we have a lot of phytotoxicity, there are residual phytotoxicity of soybeans and corn, and post-emergence herbicides. I think that they have sprayed a lot of things to alleviate the phytotoxicity. I just think about cutting off the medicinal leaves. Is it better? Seeing the helplessness and anxiety of the uncle, suddenly, the blood Upward, deep breath, I quickly stopped the uncle's wrong behavior.
When corn produces herbicide phytotoxicity, fertilizer damage and Plant Growth Regulator phytotoxicity, cutting corn leaves can not solve the phytotoxicity. The correct way is to take correct remedial measures to accelerate the metabolism of corn and harm the body. Excreted from the body. After cutting off the corn leaves, the photosynthesis of the corn is seriously reduced, which will greatly slow down the detoxification ability of the corn itself. This will not only help the corn to resume growth quickly, but will seriously affect the yield and quality of the corn.
Corn herbicide remedy
In the field, the field inspection should be strengthened within one week. Once the phytotoxicity is discovered, the corresponding technical measures should be immediately used to remedy the medicinal damage according to the different types and dosages of the drugs and the degree of hazard that may be caused by the prediction.
1. For the soil-treated herbicides, the phytotoxicity caused by excessive dosage can be used for cultivating, continuous irrigation, drainage, repeated rinsing to alleviate the phytotoxicity; and a certain amount of lime powder can be applied during watering. The acidic herbicide is neutralized, whereby the residual agent is washed and discharged, and the residual herbicide content in the soil is reduced. At the same time, strengthen field management and enhance corn resistance.
2. Strengthen field management and promote early growth of seedlings. The phytotoxicity caused by contact-killing herbicides can generally recover on their own when the damage is light; it can strengthen field management, cultivating loose soil, chasing quick-acting fertilizer and watering.
At the same time, it is necessary to spray 1%~2% urea or 0.2%~0.3% potassium dihydrogen phosphate solution on the leaf surface, which is beneficial to the normal growth of corn. At the same time, it should also actively prevent other corn pests and diseases to improve the ability of corn to resist phytotoxicity. If the victim is too heavy, it should consider replanting, replanting or destroying the plant, so as to avoid serious production or production.
3. Apply plant growth regulators to promote growth. May be applied to corn seedlings when the corn is damaged by hormonal herbicide 2,4-D butyl ester, herbicide, etc., or the phytotoxicity of the systemic herbicide and the herbicide residue of the former crop. Brassinolide or foliar fertilizer;
It can also be sprayed with ash, 1% lime water, etc. to stimulate the growth; immediately after spraying, water should be added to dilute the concentration of residual liquid in the soil to alleviate the degree of phytotoxicity and remedy. In addition, if it is predicted that the soil residual agent of the former crop will endanger the corn, the activated carbon may also be used to coat the seed to prevent phytotoxicity.
4. Application of herbicide antidote. Herbicide antidote can reduce or eliminate the toxicity of herbicides to crops. For example, selective seed dressing protectants can be absorbed by seeds and inhibit herbicide damage to crops in roots and leaves. These drugs can protect corn from herbicides such as acetochlor and butachlor.
5, timely replanting and destroying seeds: If the corn field is too harmful, if the above measures still can not alleviate the degree of damage, then only the destruction or replanting of other crops can be taken to avoid causing greater losses. (planting large household reference)

Antioxidants in the human body are synthesized by themselves and provided by food. Enzymatic and non-enzymatic antioxidants play an important role in preventing exercise-induced oxidative damage. Supplementing plant active selenium to enhance antioxidant capacity is beneficial to exercise the body to reduce the production of free radicals or accelerate their clearance. This catagory includes Cosmetic Raw Material with anti oxidant effects, such as Glutathione, Alpha lipoic acid, Coenzyme Q10, etc
