How to prevent and control coccidiosis in nutria? Farmers need to master the methods
Pathogen 1 The pathogen of coccidiosis (C. ccidiosis) is the coccidium of the class Sporozoa, a parasitic single-celled protozoan. Coccidia parasitize the epithelial cells of the small intestinal mucosa, and through asexual reproduction (schizogony) for many generations, they produce many new individuals. After several schizogonic

How to prevent and treat filamentous bacterial disease in prawns? Methods farmers must see
(1) Pathogen The pathogens are Leucothrix mucor, Thiothrix (TAiothrix) and Flexibacter, etc. Leucothrix is filamentous, unbranched, slightly thicker at the base and slightly narrower at the tip, with a length of 5-500 microns or more. It reproduces by conidia and develops into new bacterial cells.

Control Methods for Fusarium Disease in Shrimp Farming
(1) Pathogen: The Fusarium species include Fusarium solani, Fusarium oxysporum, Fusarium tricinctum and Fusarium graminearum. The fungal body is filamentous and branched, often with septa. Reproduction occurs by forming macroconidia, microconidia

Control Methods for Ichthyophthirius multifiliis Disease in Farmed Yellow Catfish
(1) Pathogen: Ichthyophthirius multifiliis. (2) Symptoms: On the skin, fins and gills of diseased fish, small white cyst-like spots can be seen with the naked eye; in severe cases, the body surface appears to be covered with a white film. Diseased fish respond sluggishly or float at the water surface. Due to bacterial infection at the affected sites, the fish body surface becomes inflamed, or locally necrotic, scales fall off, fins split diagonally, gill epithelium proliferates, and death occurs due to impaired movement and difficulty breathing in the gill area.

Control Methods for Bump Disease in Eel Farming
Pathogen: Eimeria anguillae is the pathogen of eel bump disease, belonging to the order Microsporida. The spores are small and simple in structure. Eimeria anguillae parasitizes the muscles on the sides of the body, and the spores spread inside and outside the muscle tissue, while dissolving the surrounding tissue and causing the body surface to sink inward, presenting an uneven, bumpy appearance, hence

The pathogenesis and control methods of hyacinth bean brown spot disease
Hyacinth bean, Lablab purpureus (Linn.) Sweet, commonly known as bian dou, with aliases huolian biandou, tengdou, yanli dou, quedou, chadou, yueliang cai, belongs to the Dicotyledoneae class. There are also many varieties, such as: white hyacinth bean, purple hyacinth bean, oil bean, snake bean, pig's ear bean (shaped like a pig's ear). ⟦4 <p>Hyacinth bean, Lablab purpureus (Linn.) Sweet, commonly known as bian dou, with aliases huolian biandou, tengdou, yanli dou, quedou, chadou, yueliang cai, belongs to the Dicotyledoneae class. There are also many varieties, such as: white hyacinth bean, purple hyacinth bean, oil bean, snake bean, pig's ear bean (shaped like a pig's ear). It is a perennial, twining vine plant of the genus Lablab in the Fabaceae family. It is a type of legume plant.</p><p></p><p>The pathogenesis of hyacinth bean brown spot disease:</p><p>Hyacinth bean brown spot disease, also known as brown-edged white spot disease, mainly damages leaves. Nearly circular or irregular brown spots appear on the front and back of the leaves, with reddish-brown edges, 1 to 10 mm in diameter, and later the center of the lesion turns grayish-white to grayish-brown. Under high humidity, grayish-black mold-like growth appears on the lesions on the underside of the leaves. The pathogen overwinters in the soil as ascocarps with diseased residues. In the following year, primary infection is caused by ascospores produced by the overwintering pathogen, which spread by wind and rain, and ascospores produced in diseased areas spread by airflow. This disease is a high-temperature, high-humidity disease. Under high-temperature and rainy weather conditions, with a temperature of 20 to 25°C and relative humidity above 85%, it is prone to occur.</p><p>Control methods for hyacinth bean brown spot disease:</p><p>1. Agricultural measures: rotate with non-legume vegetables for 2 years. Plant at a reasonable density, apply more potassium fertilizer, clean the field, and collect and burn diseased residues.</p><p>2. Seed disinfection: pre-soak the seeds in cold water for 4 to 5 hours, then transfer to 50°C warm water for a brief soak of 5 minutes.</p><p>3. Chemical control: apply pesticide promptly at the early stage of the disease. You may choose 80% zineb wettable powder at 500 times dilution, or 45% amobam aqueous solution at 1000 times dilution, or 50% thiram wettable powder at 600 times dilution, or 25% metalaxyl wettable powder at 800 times dilution, or 20% benalaxyl emulsifiable concentrate at 350 times dilution, or 40% fosetyl-aluminum wettable powder at 200 times dilution, or 66.5% propamocarb aqueous solution at 800 times dilution, or 50% captan wettable powder at 450 times dilution, etc. for spraying. Spray once every 10 days, and carry out continuous control 2 to 3 times.</p>
