How to prevent vegetable virus disease? The key to preventing vegetable virus disease!
According to Xiaonong.com, we understand that the invasion of diseases during vegetable planting is the most troublesome, so we must prevent it during the planting process. The above is the prevention and control of vegetables (tomato, pepper, cucumber, etc.) The key point of viral disease, I hope to help the growers!
1. Improve crop resistance and enhance immunity. (Like human beings, it is resistant to disease, so rejuvenating plants is the key)
In daily management, many planting friends can easily ignore this point. It is always believed that the prevention and treatment of diseases requires medication, but for vegetable virus diseases, the enhancement of plant resistance should be placed in the first place. For example, spray amino acid foliar fertilizer - [Wofengsu] supplement nutrients can significantly enhance plant resistance and improve antiviral ability.
2, sometimes the virus is easy to mix bacteria
For example, stripe virus disease often mixes bacteria, and it can be mixed with virus agents and bacterial agents.
3. Appropriate supplementation of trace elements
The occurrence of viral diseases is related to trace elements such as zinc deficiency. Spraying zinc sugar can help prevent and control the virus.
4, according to the medication is very important
The prevention and control of viral diseases is different from the prevention and control of eubacteria. Many cytotoxic agents directly kill the tissue structure of the pathogens; while the viral diseases live in the living cells of plants, and the spray of the drugs can only be absorbed into the plant cells. Then passivate the virus activity, inhibit the replication, reduce the harm, and make the crop not obvious, so it is difficult to achieve the healing effect once, and it must be continued. It usually takes 3-4 times for the drug, about once every 4 days.
Note: In order to absorb more liquid, it can be sprayed with silicone penetrant to improve the efficacy.
5, control the media (that is, to cure the virus must first cure the insect)
Insect pests (whitefly, aphids, thrips, etc.) are the main vectors of the virus. They must be sprayed regularly to kill aphids, whitefly, and thrips agents such as imidacloprid, whitefly 虱1, ruka (thiazide, high fluorochloro), etc. Locust - Avi 哒螨 Ling, Jin Kezhen and so on.
6, must pay attention to field operations.
Most of the viral diseases are transmitted through the wound, and the spread of insect pests (whitefly, aphids, thrips, etc.) is one aspect. Field operations such as slings, fruit picking, and leaf picking must first be healthy, re-sick, or not managed. .
7, pay attention to grasp the critical period of prevention of viral diseases
It has been proved by practice that the seedling stage and the pre-growth stage, such as the early flowering stage, are all susceptible stages of viral diseases, so prevention should be mentioned. You can choose [Vegetable Virus Dedicated or TY Virus No. 2]
8, high temperature, drought is the pathogenesis of viral diseases.
In the hot season, the shade is cooled and the water is poured.
9. When pulling out the garden, pull out the plants and keep a lot of roots in the soil.
The soil should be watered before the garden is removed, and the plants will be pulled out after two or three days, otherwise a large amount of roots will remain in the soil.
The above is the key point of the disease prevention and control of vegetables (tomato, pepper, cucumber, etc.) organized by Huinong. The growers have a quick look!
