What diseases can okra treat, symptoms and prevention methods of okra virus disease

Because the mucin in okra has the effect of inhibiting sugar absorption, it has been used as a home remedy for diabetes in recent years. And this home remedy is super simple: okra soaked in water.

The method is like this: take two fresh okra, remove the head and tail, slice, a cup of boiling water at room temperature (ps: cool the boiling water to room temperature), and then put the okra in boiling water to soak for one night, wait until the next morning, filter the residue and drink it on an empty stomach, and some sugar friends begin to lower their blood sugar after two weeks.

1. Okra tender fruit contains a viscous liquid and arabinan, galactosan, rhamnosan, protein, etc., which can be eaten regularly to help digestion, enhance physical strength, protect the liver, and strengthen the stomach and intestines.

2. Okra contains a variety of nutrients such as iron, calcium and sugar, which has the effect of preventing anemia.

3. It contains vitamin A and carotene, which are beneficial to retinal health and maintenance of vision.

4. It is rich in trace elements such as zinc and selenium, which can enhance the body's anti-cancer and anti-cancer.

5. It is also rich in vitamin C and soluble fiber, which not only has a health care effect, but also can make it whiten and delicate.

6. Okra is also rich in calcium. Its oxalic acid content is low, so the absorption and utilization rate of calcium is higher, which is better than milk, and is a good calcium for vegetarians and developing children**.

Okra virus disease occurs, and the symptoms are obvious in the delicate leaves at the top, and the leaves are mainly manifested as deformed flowers and leaves or brown markings of necrotic spots. Okra virus disease is mainly transmitted by the aphid large spike worm, which generally has low soil organic matter content and is not well managed. The fields and surrounding areas are overgrown with weeds, and the occurrence of disease is relatively serious. In the early stage of the disease, the virus is used to clear WP, or virus AWP, 3 times, and once every other week.

Okra virus disease symptoms.

Okra may have viral diseases during the growth period, and the damage is more severe at the adult stage. From the seedling stage to the early growth stage, the symptoms are obvious in the top delicate leaves, and the leaves mainly show deformed flowers and leaves or brown markings necrotic spots.

Okra disease and group poison disease hazards.

At the onset of okra virus disease, the veins of young leaves fade green and become shrivelled. As the disease progresses, the diseased leaves thicken, the petioles and internodes are shortened, the leaves are deformed, and the plants become dwarfed. The growth and development of the whole plant is slow, the flowers and fruits are thin and small, and even cannot flower and bear fruit in severe cases.

Okra virus disease causes.

Okra virus disease is mainly transmitted by aphids, and the soil organic matter content is generally low, and the management is not good; The field and its surroundings are overgrown with weeds, and the occurrence of viral diseases is relatively serious.

What medicine is used for okra virus disease.

Okra virus disease can be sprayed with viral AWP, which generally takes seven or eight days to be effective. If it is in the early stage of the disease, the virus A500 or 83-antibiotic spray can be used to control aphids, generally sprayed once a week, 3-4 times in a row, can cut off the transmission of the virus.

**Okra virus disease specific medicine.

In the early stage of okra, it is used to clear WP with bacterial poison, or virus AWP, phytophytoling, anti-antagonist and other agents for prevention and control 3 times, and once every other week has a special effect.

Okra virus disease prevention and control methods.

1. Strengthen cultivation management: Cultivate okra seedlings, increase base fertilizer, pay attention to timely watering, and have sufficient sunlight to make the plants grow strong and improve disease resistance.

2. Kill aphids and prevent diseases: Remove weeds in and around okra fields in time to prevent aphids from breeding and multiplying. The control of aphids should be strengthened at the young stage of the plant.

3. Pharmaceutical prevention and control: After the onset of okra in the field, remove the seriously diseased plants as soon as possible to reduce the source of poison transmission. At the same time, you can choose to use bacterial poison clear wettable powder, or phytolingling wettable powder, etc., once every 7-10 days, continuous spraying prevention and control 2-3 times.

1. Aphids, aphids are a common pest that can harm a variety of plants, including okra. Aphids are the most harmful to the whole growth period of plants, especially to the adult stage, they will absorb the sap of the plant, which is not good for the growth of the plant, and will also reduce the quality of the fruit. Generally, it is eliminated with insecticides such as imidacloprid, and can also be killed by spraying such as aphid lice.

2. Ants. Ant infestation mainly occurs during the flowering period, and after the flowering period is over, ants will gather on the flowers and absorb their pollen to dry, which will affect the quality of the fruit and need to be treated immediately. If you want to get rid of ants, you can generally use Lesben EC solution or Ruijin EC solution to make a spray, or you can mix Ruijin special agent into wood chips and put it in a place where ants often appear.

3. Moths. Moths are generally buried pests during the ripening period of okra, and because they appear at night, they are difficult to prevent. These pests eat the leaves so that the plant cannot photosynthesize to produce nutrients, affecting the development of the fruit and reducing its yield.

In order to eradicate them, prevention and control must be carried out with a safe EC solution, and not sprayed a week before harvesting.

4. Earth tiger. The ground tiger also has the characteristics of diurnal and nocturnal, it mostly occurs in the seedling stage of okra, eating its young stems, which will cause seedlings to break. To catch it, you can soak it in water with paulownia leaves or lettuce, place the soaked leaves on the ground, and turn the leaves the next day to catch the larvae.

In addition, phosphine EC and dichlorvos can also be used as pesticides.

Brown spot disease. Brown spot disease is very harmful to leaves. Usually, a round brown spot is produced on the leaves.

The germ can be spread by rainwater, and the remaining germs attach to the leaves and cause the disease. To prevent the occurrence of the disease, the plant spacing can be expanded, and good ventilation can effectively prevent the occurrence of the disease. During the onset of this disease, it is necessary to water less and fertilize less, and spray certain drugs appropriately for prevention and control.

Botrytis cinerea. Botrytis cinerea generally occurs in the middle of growth and can cause damage to the stems and leaves of plants. The germs of this stuffy chakra cake remain in the soil, and when spring comes, it invades the plants with the air falling from the sky.

When encountering this disease, you can use more fertilizer and frequent watering, which can improve the disease resistance of plants. Combined with a certain amount of medicine, it will slow down the damage caused by the disease in a short time. It can cause diseases of plant roots and seedlings.

At first, lesions of different shapes appear, then lesions turn black, rot, and the plant dies. The diseased part of the plant produces white filaments that can even penetrate the leaves. The disease is transmitted by water, and the bacterial survival rate is high in low-lying areas of farmland, which is an important problem for plant infection.

Usually, diseased plants can be ** and properly watered to avoid standing water. Concomitant spraying with drugs can be effective.

There are flowers, seeds and roots that are curative of sores and carbuncles, and have a certain anti-cancer effect.

Okra [main use] tender fruit (pod) flesh is tender, smooth, unique flavor, high nutritional value, can be fried, cooked, cold dressed, canned and quick-frozen processing. Young fruits also contain a viscous substance, which can help digestion, gastritis, gastric ulcers, and can protect the liver and enhance human endurance. Young leaves are also edible.

There are flowers, seeds and roots that are curative of sores and carbuncles, and have a certain anti-cancer effect. The seeds contain more minerals such as potassium, calcium, iron, zinc, and manganese, which can extract oil, protein, or as a substitute for coffee.

Processing and eating methods Okra can be eaten in a variety of ways, including cold dressing, stir-frying, frying, and soup. The main ways to use it are as follows:

1) Gently cut off the fruit pedicle, put it in boiling water for 2 3 minutes, remove it, rinse it with cold water, cut it into thin strips, and add various condiments to prepare.

2) Stir-fry After removing the stem, put it in boiling water for about 30 seconds, remove the water, and cut it into slices with a thickness of 1 cm for later use. Take the lean pork slices, put them in the oil pan and stir-fry, then add the okra slices, stir-fry quickly, add seasonings, and put them on the plate.

3) Fry take an appropriate amount of flour, add 1 egg, adjust the water to a paste, and the seasoning is appropriate. Wrap the stemmed okra in batter, fry it in an oil pan until milky brown, and dip it in seasonings to eat.

Common leaf spot, rust and aphids, beetle damage. Before the occurrence of the disease, it can be sprayed with the same amount of Boerdeaux liquid plate for prevention. The right insect pests were sprayed with 500 times carbaryl wettable powder.

Okra fruits were refrigerated (-18) by quick-freezing method to study its effect on the main quality of okra fruits and their storage and preservation period. The results showed that okra had a shelf life of up to 9 months after blanching and quick-freezing. After quick freezing, the fruit is vacuum-packed, with minimal nutrient loss during storage.

Okra has fewer pests and diseases, and the main insect pests are: cotton bollworm, bridge-building insects, aphids, thrips, etc. Viral diseases have.

Leaf coal disease, etc. Cotton bollworm and bridge-building insect mainly damage the fruit, which can be sprayed with 50 phoxanthion EC 1500 2000 times; Aphids and thrips mainly damage fruit pods, and can be sprayed with 40 dimethoate 1500 times.

Pollution-free prevention and control of leaf coal disease:

1) When cultivating okra in the shed protected area, special attention should be paid to ventilation and humidity to reduce the incidence or non-occurrence of disease.

2) In summer, the high temperature and stuffy shed at noon can kill the residual germs, and the leaf coal pathogen can die in a short time under the condition of 50 high temperatures. When it is used in production, it must be tested according to the variety of cultivation to avoid burns.

3) If necessary, 60% carbendazim hydrochloride (anti-mold treasure) soluble powder 600 times solution, (Bankunin, carbium, Bangbanke, bactoxin, promecarb, carb) suspension 500 times.
