How to prevent and control red and white plastron disease in soft-shelled turtles? Detailed explanation of causes and prevention methods
Red and white plastron disease in soft-shelled turtles (commonly known as red plastron and white plastron disease) has been a relatively serious turtle disease in China in recent years, and so far there is still no ideal treatment method. However, through efforts in various aspects, the main pathogens and disease onset conditions of red and white plastron disease have basically been identified, and breakthrough progress has been made in prevention, especially in research on disease prevention with Chinese herbal medicines and immune vaccines, laying a foundation for controlling the occurrence of red and white plastron disease in the future. Based on relevant domestic research and my own practice, the author introduces the occurrence and prevention of red and white plastron disease as follows, for reference and application by interested parties.

What are the pest and disease control methods for Chuanxiong (Medicinal cyathula, Cyathula officinalis)?
The main disease during the growing period of Medicinal cyathula (Cyathula officinalis) is white rust. The symptoms of this disease are that all aboveground parts of the plant can be affected, manifesting as damage to the leaves, with pale yellow-green patches appearing on the leaf surface and corresponding blister-like protrusions growing on the underside, 1-2 mm in diameter. After the epidermis ruptures, a white, glossy, sticky-slimy powdery substance is released. When many blister spots occur, the diseased leaves turn yellow and brown. When it occurs on parts such as leaf petioles and young buds, pale yellow spots are produced, which later become white blister spots, and the diseased stems are often swollen and twisted. The pattern of white rust development is that the pathogen mainly overwinters as oospores

Detailed Explanation of the Pathogen and Epidemiological Characteristics of Swine Vesicular Disease
This disease is an acute infectious disease caused by the swine vesicular disease virus. Usually, only pigs can be naturally infected by this disease, while other animals such as cattle and sheep are not easily infected, so it can be distinguished from foot-and-mouth disease. The disease is characterized by vesicles on the skin of hairless parts of the pig's body and on the oral mucosa. Vesicles and erosions also occur on the skin of the coronary band, interdigital space, and heel, and around the teats of sows. This disease is widely distributed and spreads rapidly. It was first discovered in Italy in 1966. By the 1970s, after successively becoming epidemic in the United States, Austria, Hungary, and other Eastern and Western European countries, it also occurred in Japan

It mainly harms piglets, affecting their growth and development and reducing meat quality. Severe infection can cause pneumonia and lead to death. Symptoms: When pigs have a mild infection, there are no symptoms or they are not obvious; with severe infection, the symptoms are pronounced. More than one month after infection, pigs show symptoms such as paroxysmal coughing, thick yellow mucus flowing from the nose, rapid breathing, pale conjunctiva, reduced appetite and weight loss.

Symptom Identification and Control Methods for Cotton Brown Spot Disease
Symptoms The disease mainly affects leaves. When cotyledons are infected, pinpoint-sized purplish-red spots first appear, then expand into brown, purplish-edged, slightly raised round to irregular lesions; multiple lesions merge together to form large patches, with small black dots scattered in the center, which are the pathogen's pycnidia. The center of the lesion easily breaks off and falls out, forming holes, and in severe cases the leaves drop off. On true leaves, the lesions are round, yellowish-brown, with purplish-red edges. Pathogen Phyllosticta gossypina Ell. et Mart., called cotton Phyllosticta leaf spot
