In recent years, more and more herbicides have occurred during the cultivation of grapes. How should it be prevented? Agri-net editor Xiaobian and you to understand together. I. Isolation: In the current situation, the use of herbicides cannot be limited. The most effective measure that we grape growers can take is isolation. The first is to protect the production of grapes; the second is when the cultivation of open fields, after the unearthing of temporary shelves, in the middle of May to see nearby corn growers spraying herbicides, the use of plastic film to cover the grapes, avoid spraying herbicide peak After that, put the grapes on the shelves for normal management. Second, spray water or antidote: If you do not isolate the grapes, it is necessary to pay attention to the emergence of haze before and after the rain, the grapes sprayed with water or alkaline pesticides, such as lime sulfur, Bordeaux mixture. Because herbicides are generally classified as acidic, alkaline substances are easily decomposed. However, it should be noted that it is best to spray clean water or alkaline pesticides, or else the sensory symptoms appear before spraying. The effect is poor. Third, to strengthen comprehensive management: Herbicide damage to grapes is generally temporary. After the grape is found damaged, it is necessary to strengthen comprehensive cultivation and management such as fertilization and irrigation so as to restore the tree potential as soon as possible. When the shoots and shoots are picked up in summer, they should be left for a few days, leaving a few more leaves. In short, China Agricultural Resources Network considers different types of herbicides, the methods of rescue will be somewhat different, but the usual practice is: watering, to achieve the purpose of washing off part or dilution of herbicides; fertilization, mainly in the plant growth period Shi Ye Fertilizer, enhance the resistance of plants in order to achieve the purpose of reducing injury.
