How to prevent and treat viral diseases? What virus can be completely treated?

Viral diseases are whole-plant diseases. The leaves appear yellow-green flowers and leaves, the surface is uneven, and there are black lesions, resulting in early leaf death, plant growth dwarf, and severe plant death. It is usually caused by viral infection.

Control methods: select disease-resistant varieties and select disease-free mother plants to keep seeds; timely spraying to eliminate poison-carrying insects, such as aphids, seed flies, etc.; Increase the application of phosphorus and potassium fertilizers to promote the growth of plants and enhance disease resistance.

Capsicum virus disease has a variety of symptoms such as fern leaves, mosaic leaves, bright veins, dwarfing, yellowing, necrosis, apical wilt and deformity.

1) Mosaic leaves. The leaves showed irregular dark green and light green spots, and the heart leaves were found in the field, indicating that the plant had been infected with viral diseases. Mosaic leaves are divided into two types: light mosaic leaves and heavy mosaic leaves, light mosaic disease leaves appear slightly green at the beginning of the bright veins, or appear thick and light green mottled, and the mosaic leaves do not shrink.

In addition to showing green and mottled leaves, the leaf surface is uneven, the leaf veins are shrunken and deformed, or the linear leaves are formed, the growth is slow, the fruit becomes smaller, and the dwarf is severe.

2) Fern leaves. The leaves become smaller, shrinking, twisted, and clumped.

3) Dwarfing. The plant becomes shorter, often at the same time as fern leaf clustering.

4) Yellowing. The diseased leaves turned yellow obviously, and the phenomenon of defoliation appeared, and the distribution in the field was uneven.

5) Mingmai. The veins of the leaves become pale and translucent.

6) Necrosis. Some of the tissues of the plant turned brown and died, which was manifested as stripe spots, top wilt, necrotic mottled spots and ring spots.

7) Deformity. The diseased plant is deformed, such as the leaves become linear, i.e., fern leaves, or the plant is dwarf, with many branches, and is clump-like.

Sometimes the above symptoms appear on the same plant, or cause leaf loss, flower loss, and fruit drop, which seriously affects the yield and quality of peppers.

Seedling prevention, no virus disease in one season, the initial onset is very fast, the effect can be clearly seen after a medicine, the mid-term use of three times of medicine, the later stage of the use of flower and fruit, the late stage of the disease of more than 85% is not recommended in the drug, basically no value. WeChat search: plant-derived biological pesticides.

After paying attention, you can see the actual disease situation of many crops and the method of using the body and medicine.

There are two thorough divisions here, one is to find a solution to reduce disease morbidity and mortality; The other is that the virus has completely disappeared from the world.

First of all, let's talk about the solution to the problem, what are the viruses that can be **?

The first is rabies, once rabies is onset, there is no way, the patient is afraid of water and wind, and the death is miserable, but now under science and technology, people have a vaccine and immunoglobulin to prevent rabies, which can almost control the occurrence of rabies, and the incidence of rabies in the world is very low at this stage.

The second is the influenza virus, although the spring and winter of each year are still the peak period of influenza, but the influenza usually has a certain degree of self-limiting, and the body can regulate itself for a certain period of time. And you can take drugs such as oseltamivir for prevention, and within 48 hours, you can also block the virus, which almost minimizes the impact of influenza on humans.

Let's talk about the virus that was completely eradicated - smallpox, when smallpox was epidemic, the incidence rate was high, the fatality rate was high, and the recovery effect was very poor, since the vaccinia vaccine was inoculated worldwide, and the smallpox virus itself had a high demand for the host, and finally human beings eliminated smallpox, which is also the only virus in human history that has been completely defeated theoretically.

In fact, many viruses are not incurable at this stage, such as hepatitis B virus can be effectively blocked slowly, and the life length can be prolonged after AIDS, although they cannot be avoided, but they can effectively prolong the course of the disease and improve the recovery effect. Viruses are also a kind of nature, and it is almost impossible to defeat all viruses, and learning to get along with them, doing a good job of prevention, and reducing the harm of viruses to human beings is what we should gradually do at this stage.

1: All system vulnerability patches are played!

2: Install a spybot or webroot to deal with ad spies 3: Install ewido to deal with Trojans!

4: Equip the Ice Blade to deal with an unknown hidden Trojan that ewido can't detect!

5: Install hijackthis to monitor the system at all times for abnormality!

6: Install Kaba, the king of shelling! (Coffee Norton and the like do not properly unshell some Trojans with encrypted shells, but by adding the characteristic code of the shell to detect and kill).

7: Install nod32, heuristic cool kill, intelligent antivirus! It's useless to deal with him, modify the feature code or spend instructions, you can only use the shelling and then encrypt, but we already have Kaba, the master of shelling).

8: That's all for the time being!

Don't think of viruses as the root of all evil, I'm still a free antivir, automatic upgrade, it's hard to scan the virus once a month, and there is no virus yet. It also does not affect the running speed of other software, it has been three years, and the system has not been reinstalled except for the automatic upgrade of the system.
