Chinese cabbage anthracnose is a serious fungal disease that not only affects Chinese cabbage but also other cruciferous crops like mustard, radish, and turnip. This disease significantly reduces crop yield and damages the commercial value of vegetables. The disease thrives in warm and humid conditions, typically when temperatures range between 26°C to 30°C and relative humidity exceeds 95%. Factors such as high plant density, low-lying fields, poor drainage, and insufficient fertilization can increase the likelihood of infection. Weak plant growth, inadequate sunlight, and poor air circulation also contribute to the spread of the disease.
Symptoms of the disease first appear as small, pale or greenish spots on the leaves. These lesions are usually round or nearly round, with brown edges, slightly raised margins, and a grayish-white center that is thin and translucent. As the disease progresses, the lesions become more pronounced, turning gray and easily rupturing. The disease can damage the veins on the leaf surface, causing brown spots of varying lengths and depressions. The petioles, stems, and seed pods may also be affected, resulting in elongated or spindle-shaped, brown or gray-brown lesions. When the infected areas are moist, they often exude a red, sticky substance.
For early prevention and control, it is recommended to spray 2% antifungal solution diluted 200 times. Apply this every 5 to 6 days for 2 to 3 applications. Alternatively, you can use 80% carbendazim wettable powder diluted 600 to 800 times, or 50% chlorothalonil wettable powder at the same dilution. Another option is 50% mancozeb wettable powder diluted 600 to 800 times. These treatments can also help manage other fungal diseases like gray mold caused by Sclerotinia.
Additionally, you can spray 40% Benlate wettable powder at 400 to 500 times dilution, or mix 70% thiophanate-methyl wettable powder with 75% chlorothalonil wettable powder, both at 1000 times dilution. Other effective options include 50% benomyl wettable powder diluted 1000 times, 70% mancozeb wettable powder at 500 times, or 25% triadimefon emulsifiable concentrate diluted 3000 to 4000 times. Apply these treatments every 7 to 10 days, repeating 2 to 3 times for best results. Regular monitoring and timely application of fungicides are crucial for effective disease management.

Medical tools for surgery:
1. Scalpel: A surgical knife used for making incisions in the patient's skin or tissues.
2. Forceps: A tool used for grasping and holding tissues or organs during surgery.
3. Retractors: Surgical instruments used to hold open incisions or wounds to provide better visibility for the surgeon.
4. Scissors: Used for cutting tissues and sutures during surgery.
5. Hemostats: Used to clamp blood vessels and prevent bleeding during surgery.
6. Suction devices: Used to remove fluids or debris from the surgical site.
7. Needles: Used to suture or stitch wounds.
8. Electrocautery: A tool that uses an electrical current to cut or coagulate tissues during surgery.
9. Endoscopes: Used for minimally invasive surgeries, these instruments allow the surgeon to see inside the body without making large incisions.
10. Laparoscopic instruments: Used for minimally invasive surgeries, these instruments include a camera and specialized tools for performing surgery through small incisions.
