Oyster mushroom rust spot is a common disease of oyster mushroom, what are the symptoms of oyster mu

Oyster mushroom rust spot is a common disease of oyster mushroom, and the symptoms of oyster mushroom rust spot are rusty brown spots on the cap and stipe of oyster mushroom. And the reason for its occurrence is the high humidity of the environment.

Pleurotus ostreatus rust spot disease is a rust-colored or dark brown spot on the cap and stipe of Pleurotus oysterus, which is a sexual disease that is prone to occur in the fruiting body growth stage of Pleurotus oysterus.

You will find that the surface is all yellow, and there are brown spots on it, which makes it look like the mushroom is broken, and there is some slime, which also smells.

If rust spots occur, ventilation should be strengthened to reduce relative humidity. Drug control can be sprayed with 5% lime clarifier, 1:600 times of bleaching powder, 500-800 times of aqueous solution of amber antiseptic, oxytetracycline, streptomycin, gentamicin or chloramphenicol solution containing 120 units per milliliter, or a mixture of 3 parts of bleaching powder and l parts of soda ash.

Medications** can be used. Some pesticides can prevent rust spots in oyster mushrooms.

Spraying. Because spraying can effectively prevent rust spot disease, my oyster mushrooms are sprayed every year, and I have never had this disease, so I should spray some medicine.

When cowpeas have two leaves and one core, they can be transplanted into the field. After cowpea transplantation in the field or after the emergence of seedlings, it is necessary to cultivate and weed, clear the ditch and drain the water to prevent the soil from being wet, after the seedlings emerge, use 25 kg of human manure and urine to mix 25 kg of water, add 250 grams of urea to raise seedling fertilizer again, and then set the seedlings and eliminate the weak seedlings.

It is easy to develop embroidery spot, especially in the period when cowpea grows vigorously and forms a clamp, if a large rust spot occurs on the leaves of cowpea, it will cause cowpea to only bloom without clamping, or too few clips, and in serious cases, it will reduce a large amount of yield, or cause cowpea growth period to be shortened, shrink and die. Susceptibility. Rust mainly affects the leaves of cowpeas.

From the initial yellow dots, it gradually spreads throughout the leaf, and eventually causes the leaf to lose the ability to photosynthesize, wither and fall. Rust will cause the leaves to fall early, affecting the normal growth of beans, and the small size of the plant will have a greater impact on the yield.

Warm and heat-resistant, but not frost-resistant, it has a lot of pests and diseases during the growth and development period, there are coal mold, also called leaf spot, virus disease, anthracnose, root rot, blight, horn spot, gray mold, rust, etc., now mainly introduce cowpea rust. After the sores are broken, they emit a reddish-brown powder, which produces greenish spots on the front of the leaf surface with sores, and when the disease is severe, the leaves will dry up and fall off quickly, which has a great impact on the yield, and it will also occur on the pods, the symptoms are similar to those on the leaves, but the shape is larger.

Generally, it can happen in the open field and in the greenhouse in summer. Once infected with this disease, if the correct control measures are not taken, cowpea leaves will fall, affecting yield and commerciality. In the first year we planted cowpea, due to the lack of pest control of cowpea, rust occurred in a large area, and the entire leaf fell off in less than a week, and thousands of pieces were lost in a shed.

The key to high yield of beans is to repel underground pests, isolate virus infection, improve germination rate, choose a pastoral with high terrain and good hydrophobicity, maintain ventilation and light transmission, prevent excessive humidity, and do a good job in disease prevention and control.

Rust-colored or dark brown spots that appear on the cap and stipe of oyster mushrooms are called oyster mushroom rust spots. This disease is a sexual disease that is prone to occur during the fruiting body growth stage of oyster mushroom. The pathogen that causes the disease is Pseudomonas bacillus, which is widely distributed in nature.

Oyster mushroom rust spot is a kind of disease that is easy to occur in the growth stage, and the occurrence condition of oyster mushroom rust spot is that the ambient temperature is relatively high and the environment is relatively humid.

Crazy growth of mycelium: the surface layer of mycelium is dense with aerial mycelium, which affects the emergence of mushrooms. The reason for the crazy growth of hyphae is mainly caused by high air humidity and poor ventilation.

Ventilation can be strengthened and humidity can be reduced. Bigfoot mushroom of Oyster mushroom: The fruiting body cap is extremely small, and the stipe is thick and long.

This is mainly caused by lack of oxygen and poor ventilation. As long as ventilation is strengthened, pay attention to the light can prevent it.

1. Crazy growth of mycelium: It refers to the relatively lush growth of aerial mycelium on the surface of the mycelium of Pleurotus oysterus, which affects the situation of mushroom production.

2. Oyster mushroom Bigfoot: This disease is mainly due to the phenomenon that the cap of the fruiting body of Oyster mushroom is very small and the stipe is very thick and long caused by long-term hypoxia and poor ventilation.

It usually occurs from March to May; It is severe under the conditions of high temperature, high humidity and poor ventilation, and often develops rapidly after fog or sandstorms.

First of all, it is known for a long time in a state of high temperature or high humidity, and the ventilation situation is not particularly good, generally when the wind is relatively strong and the fog is relatively large, the speed of reproduction is also relatively fast, and the grinding is served.

If the temperature is too high, the ventilation is not good, the humidity is too high, and it is infected with other germs, and there is no crop rotation, it is easy to develop such diseases.

The main reason for the occurrence is insufficient moisture and excessive ventilation. Prevention method, increase the relative humidity of the air, do not dry the material surface, and do not let the wind blow directly on the mushroom buds or fruiting bodies when ventilating.

It is because the surrounding weeds are not treated in time, or the fertility of the soil is not enough, or it may be that there is no timely watering.

It's malnutrition, lack of water, and the roots have been bitten by bugs.

Oyster mushroom atrophy disease** is mainly due to insufficient moisture and excessive ventilation, which leads to the growth of mushroom buds or fruiting bodies to stagnate, gradually shrink, dry out, die, and rot.

There are many netizens who still prefer to eat oyster mushrooms, oyster mushrooms can not only be used for stewed soup, but also used for stir-frying, which can also bring a good taste to everyone, but some oyster mushrooms will have oyster mushroom soft rot. In fact, it is easy to understand that it is a harmful mushroom, so this oyster mushroom also has some viruses. Many people say that the most common symptom of oyster mushroom soft rot is that the oyster mushroom is deformed or the oyster mushroom stops growing, and the color is dull and rotten.

Pay attention to the cultivation of oyster mushroomsOyster mushroom soft rot is still very bad, so everyone should pay special attention. Many people also said that there was such a viral infection of oyster mushrooms, which also affected its sales. Sometimes it will affect the body after people eat it, so people should be extra careful.

If such a virus appears in oyster mushrooms, then these oyster mushrooms should be treated in time. In severe cases, the land needs to be renovated well, so that the grown oyster mushrooms can have better and healthier nutrition. <>

Oyster mushrooms are more nutritious, oyster mushrooms are a relatively common vegetable, and many people think that oyster mushrooms are very delicious. In addition, its cooking process is relatively simple and convenient, which has won the love of many people. People also think that it is more delicious to cook some oyster mushrooms, and they will also choose to use oyster mushrooms to stew chicken soup.

In this way, it can also have a certain amount of nutrition for the human body, and also allows people to consume more nutrients, so the value of oyster mushrooms is relatively high. <>

Oyster mushroom soft rot is more serious, and oyster mushroom soft rot is also more serious, so everyone should pay attention to it. Sometimes, if the oyster mushroom gets this virus, then it needs to be treated in time, and people can't eat these oyster mushrooms with the virus. Otherwise, this oyster mushroom will also cause certain harm to people's body, and in serious cases, it will also have a certain impact on people's stomach.

Because the soft rot of oyster mushrooms is relatively bad, there are many oyster mushrooms that will have such a virus phenomenon, which is also hoped that farmers can deal with it in time.

Symptoms generally start from the base of the stipe, gradually expand upward, and a small part start from the cap, and finally the fruiting body is light brown water-stained soft rot. The surface of the soft fruiting body is sticky, moist and odorless.

This disease is caused by Mucormyces macromus, after the fruiting body of Pleurotus oyster mushroom is infected by the pathogen, the whole fruiting body is light yellow-brown water-stained soft rot, generally from the base of the stipe and gradually develops upward, and also from the cap, the surface of the fruiting body after soft rot is sticky and slippery, but there is no foul odor.

It is found that the roots are rotten, and they are also very fresh, and the roots are yellow.

The white hyphae grow in the form of a spider web on the surface of the bed, covering the bed surface, surrounding the fruiting body, and the pathogen spreads upwards along its stipe, and finally reappears as the fruiting body stops growing, and the color is dark, and it quickly softens, yellows, browns, and then decays.

Pay attention to the temperature of planting, but also pay attention to the spread of pathogens, and at the same time spray pesticides in advance, strangle the virus in the cradle in advance, and pay attention to management techniques.

Spray pesticides. Because after the pesticide is applied to the oyster mushroom, the melasma disappears, so I can apply pesticides.

Miscellaneous mushrooms that harm oyster mushrooms: mainly oyster mushrooms, mucor mold, aspergillus, rhizopus, bacteria, viral diseases, bacterial brown spots, macular disease, etc. Chloroderma is the most serious fungus that invades edible fungi, and the medium suitable for the growth of edible fungi is suitable for the growth of green mold filaments.

Oyster mushrooms are not strictly sterilized in the culture material, the disinfection is not strict during inoculation, and the environmental hygiene is not good when the mushrooms come out, and green mold can be produced. The green fungus is discarded immediately after infiltrating the culture material and the mycelium and mushrooms. Prevention method:

1. The water in the medium is adjusted to 60% to 65%, and excess water is easy to mold. 2. Keep the environment clean and dry, and do not accumulate waste and pollutants.

To maintain the hygiene of the mushroom place, the mushroom warehouse should be kept ventilated, the air humidity should be appropriately reduced, the number of watering should be reduced, and the mushroom peak should be prevented from discharging the mushroom for a long time at high temperature. 3.Pick mushrooms in time, remove residual mushrooms, break roots, remove germs, and remove polluted mushroom sticks.

4. Green fungus net injection of green fungus or Lixin fungus king or mycelium injection. The methods of preventing other diseases and preventing green mold are basically the same, and only drugs can be chosen. In addition, during operation, tools and hands should be strictly disinfected with alcohol or potassium permanganate.

The main pests that harm oyster mushrooms: oyster mushroom mosquitoes (also known as mushroom mosquitoes or mushroom maggots), oyster mushroom mosquitoes, fecal mosquitoes, flea flies, fruit flies, houseflies, moths, and noctuidae They mainly reproduce at the highest peak in autumn and winter 11 and 12 months and spring 3 and 6 months, and the egg period is 5 7 days when the temperature is suitable, and the larval stage is 10 15 days. Prevention method:

1. Remove the surrounding weeds and garbage, and maintain the environmental hygiene around the mushroom warehouse. 2. Remove the waste away from the mushroom barn; 3.Spraying or injection of mushroom Zhongshun, avei bacteria, mushroom cis, insecticide, diquat insects, insecticide, high-efficiency chlorofluorocarbons, etc.

Mites, nematodes, maggots, are mainly practical mycelium and fruiting bodies, very small in size, fast reproduction, serious damage, light yield reduction, heavy harvest, eggs ** in raw materials or culture site is not clean, poor ventilation, humidity caused by egg reproduction.

Mushroom mosquitoes, mushroom flies, jumping insects, thrips, mole crickets, rat women, these pests will have an impact on the growth of oyster mushrooms. Some will bite the bacterium, and some will go directly into the mycelium.

Pleurotus mosquitoes, flea flies, fruit flies, noctuidae and moth-eating pests will greatly harm the production and living environment of oyster mushrooms.

For example, larvae such as mushroom mosquitoes and mushroom flies can bite the fruiting body stipe to the cap into a sponge; Jumping insects, thrips, etc. will enter the folds of the human fruiting body, and it is difficult to remove them even if they are washed with water; Mole crickets and rat women will destroy the covering soil of the mushroom furrow, making it difficult for mushroom buds to occur.

The main insect pests are mosquitoes, nematodes, jumping insects, fungus flies, horseshoe, etc., so it is necessary to carry out timely prevention and control.

I want to buy oyster mushroom sticks and I don't know if ** is sold?
