Its main clinical and pathological features are fever, diarrhea, enlargement of the liver and spleen, and necrosis. The disease has a high mortality rate, and after affected birds develop the disease it causes mass deaths. Spirochetosis occurs in various parts of the world, but is most common in free-range poultry in tropical and subtropical regions. 1. Pathogen and epidemiological characteristics. Sick birds, dead birds and their excreta are the main sources of infection of this disease. Susceptible birds coming into contact with sick or dead birds and their excreta are often easily infected, and the disease can also be transmitted through the bites of arthropods, mosquitoes and poultry mites, but the main vector of this disease is Argas persicus. When poultry are naturally infected with the disease, transmission is often caused by tick bites.

How to prevent and control common diseases in the middle and late stages of Pinellia ternata growth
Tuber rot disease 1. Causes and symptoms: Occurs during high temperatures, the rainy season, prolonged excessive soil moisture, and the swelling period of tubers and bulbils. In the early stage of the pathogen infecting Pinellia ternata tubers, irregular black spots appear around the edges of the tubers, and these spots rapidly spread outward. After 3-4 days, numerous pathogen spots merge together and continue to infect the interior of the tuber. At this point, the root system of Pinellia ternata begins to shrink, and the above-ground leaves gradually turn from green to yellow and wither. After 1 week, the Pinellia ternata tubers become round and blister-like, resembling

How to prevent and control mushroom wilting disease? Remember these eight key points
1. Early prevention in the substrate mix. When using corncobs, wheat straw, or rice straw as the main material, add 5% wheat bran or 4% fermented and decomposed livestock and poultry manure at the bottom; when using nitrogen-rich cottonseed hulls as the main material, no nitrogen source needs to be added, but attention must be paid to controlling mite damage, and spraying an 800-fold dilution of trichlorfon when mixing the substrate works very well. 2. Moderate acidity and alkalinity. The amount of lime added when mixing should reach 5%, and after each mushroom harvest, spray 1% lime water or 4% plant ash water to raise the pH. 3. Ventilation and air

A Detailed Explanation of the Common Causes of Deformed Mushrooms and Their Prevention and Control Methods
The manifestations of deformed mushrooms are diverse, and the main ones commonly seen in production are: landmine mushrooms, hollow mushrooms, big-butt mushrooms, hard opening and early opening, red roots, and water rust spots. Landmine mushrooms. The main cause of their formation is that the casing soil material is too coarse, the soil texture is somewhat hard, the casing soil is relatively thick, the surface layer of the casing soil contains relatively little water, while the temperature and humidity conditions of its lower part and the substrate are suitable for the occurrence and growth of fruiting bodies, so fruiting bodies are easily differentiated and formed on the surface of the substrate or in the middle and lower layers of the casing soil, and then emerge through the soil surface. Solution: select high-quality humus soil, and according to a certain ratio
