Is there a specific drug to prevent and control black rot in the summer of centipede breeding stage?

One**. Black rot is one of the infectious diseases caused by the invasion of centipedes. When a centipede injures its abdomen when crawling on rough ground**, or when a centipede is bitten by ants or mealworms, putrefiners and staphylococci hidden on the ground of the centipede pond or centipede nest will take advantage of the opportunity to enter through the wound.

And in this or into the body to multiply in large quantities, produce toxins to poison the centipede body and cause disease. The disease mostly occurs during the humid spring period, and the spread of black rot is amplified by the introduction of these germs when the food and water are not clean, or when the dead centipede carcasses are not treated in time.

2. Symptoms of this disease are mostly injuries and infections in the anterior abdomen, the abdomen becomes black and swollen before the beginning of the disease, and the swelling and pain in the abdomen hinder activities, causing the diseased centipede to be reluctant to crawl out of the nest and lie down. Sick centipedes show a sharp decrease in appetite, from less predation to no predation, constipation followed by diarrhea, shortness of breath, blood circulation disorders, and the diseased centipede becomes emaciated. The affected part ** suffered severe ischemia, muscle decay, and black rancid fluid flowed, and finally died of extreme exhaustion.

Dead centipedes were examined, and the anterior abdomen was black and swollen, locally ulcerated, the midgut was congested and bleeding, and the blind sac was full of gas. The liver is congested and swollen, brittle and easily soluble.

3. Prevention and control 1. Prevention In the season of high humidity, it is necessary to reduce the humidity in the centipede pond and centipede nest, and remove food residues, dead bodies and feces in time. Change the water frequently, clean and disinfect the water and food trays to reduce the growth of germs. In addition, it is necessary to remove the coarse sand and stones in the centipede pond to prevent centipede damage.

2. ** 1) Wash the wound with 3 salt water to remove dirt and rotten flesh. Then sprinkle with centipede Motoyasu and finally apply oxytetracycline ointment. Once a day for 3 days.

2) If the wound is not decomposed, iodine can be applied first, and then chloramphenicol eye drops. Once a day for 3 days.

3) Dissolve 100,000 units of penicillin in water and clamp the tail of the diseased centipede. Forced sick centipedes to drink. Once a day for 3 days.

4) Add 100 grams of centipede Yuankang to the feed of mealworms per kilogram of body weight, and feed the centipedes after feeding for 1 hour. Once a day for 3 days for 5 days.

5) Add 2 grams of oxytetracycline per liter of drinking water for centipedes to drink freely. Once a day for 3 days for 5 days.

6) For each kilogram of centipede body weight, boil water with 100 grams of centipede Yuankang, filter and remove the slag, take the medicine and feed the centipede, once a day, for 3 consecutive days and 5 days.

7) For centipedes per kilogram of body weight, boil water with 2 grams of white flower snake tongue grass, 0 5 grams of gallberry, and 1 gram of licorice, filter and remove the slag, and take the medicine to feed the centipede. Once a day for 3 days for 5 days. (8) Boil 5 grams of radix root, 5 grams of charcoal mother, and 1 gram of licorice per kilogram of body weight, filter and remove the slag, and take the medicine to feed the centipede.

Feed once a day for 3 days and 5 days.

It's selling advertising. Raise hundreds of thousands. Also black rot. There is also a group number. It's very similar. Hundreds of thousands of black rot can still be cultivated. I want to trick some people into buying some seeds from you, and I want to cheat some money.

Give Zhang ** I will help you see, the content and concentration of these drugs also tell me, when will they be used? Pluck another one and see how the roots grow. Preliminary judgment of your seedlings is relatively weak, the roots can not absorb the fertilizer in the soil, and the seedlings are affected by the medicine.

Medication should be avoided at noon (10:00-14:00).

If it's really a drug damage, then remedy it. Use Yunda 120 to spray once or twice, you can,.

In the early stage of pepper, it is necessary to mainly protect the leaves, and it is enough to play chlorothalonil and tobuzin; In the middle stage, it was mainly used to protect the fruit of the flower, and the fruit of the flower was protected, and the pepper was killed, and the gray mold was prevented, and the main method was Sukelin. In the later stage, the prevention of anthracnose is the main thing, and the blue powder can be beaten, and at the same time, the middle and late stages should be topdressed.

Commonly used methods.

Radiation disinfection. Disinfection of chemicals.

Disinfectant. Steam thermal sterilization.

If you don't have a lot of soil at home, you can fry the soil in an iron pot.

Compound biological fertilizer, beneficial bacteria engulf harmful bacteria.

The focus is very poor, it should be an insect infestation, leafminer fly.

Isn't there a lot of white dots, and the leaves in that place are still bulging. It is most likely white rot or flying worm disease (a lot of small white bugs on the back of the leaves).

You're talking about the ears of corn.

If it really is so serious that it doesn't grow, then it definitely won't be polluted.

If all the corn were like that, the female ears of the corn would have no powder.

It's not just about the production, it's about not the production.

The only way to do this is to pollinate by hand.

However, the pollen required to be collected off-site is a lot of work.

It is impossible for the whole field of corn to be damaged, if a small number of damage is affected, and the distribution of the affected plants is not very concentrated, you don't have to worry about pollination, so it will not affect the yield; If there are a lot of damaged plants that affect the pollination of corn, it will affect the yield, and manual pollination is needed to improve the yield.

b. The occurrence of pests and diseases is closely related to external environmental conditions. The occurrence of diseases is caused by the adverse environment caused by climate changes, which makes crops less resistant to diseases. Favourable climatic conditions may lead to large-scale outbreaks or epidemics of diseases.

Where are you from, and you also grow yellow lotus? I've seen very good ones, but I don't know, can I help you ask...
