1. **Ulcer Disease**
Ulcer disease affects leaves, branches, and fruits. It is caused by pathogenic bacteria that enter through stomata, wounds, or lenticels. The disease thrives in temperatures between 25°C and 30°C, especially during rainy seasons or after typhoons. Leaf scab damage can also create entry points for the bacteria. Symptoms start as small yellow oily spots on the leaf surface, which later develop into round lesions. The center of the lesion becomes raised and may rupture, leaving a yellow halo around it, resembling "chicken eyes."
Control measures include spraying 0.3–0.5% Bordeaux mixture at intervals of 10, 25, and 50 days. Removing summer and autumn shoots helps reduce leafhopper populations. A copper-ammonium solution should be applied around spring buds (0.5–3 cm). Streptomycin can be used once in summer and autumn for young plants.
2. **Greasy Spot Disease**
This fungal disease causes leaf spots and affects fruit development. It enters through stomata, wounds, or lenticels. Conditions favorable for the disease include temperatures between 25°C and 30°C, high humidity, and damage from rust mites. Symptoms include rust-colored spots on leaves and red spots on early-ripening fruits. As the fruit matures, the spots become reddish-brown, resembling rust. Severe winter debris can lead to reduced yields the following season.
To control the disease, spray copper ammonium solution around spring buds (0.5–3 cm) and apply a mixture of 80% zinc mancozeb (500 times dilution) and water-soluble phosphorus fertilizer (1000 times). Spray 1–2 times each month from May to September. Apply lime (0.5–1 jin) to young fruits in late spring and early summer.
3. **Anthracnose**
Anthracnose is a fungal disease that damages leaves, shoots, and fruits. It spreads through direct infection or via wounds, especially during rainy periods. Symptoms include round or irregular brown spots on leaves with a yellow-brown border and gray center. When wet, pink mold may appear, but the fruit does not rot. Some lesions form streaks along the direction of rainfall on the fruit surface.
Control involves applying 0.5% Bordeaux mixture before bud break. Topotecan 500 times or Bordeaux mixture is recommended. Avoid using copper ammonium if spider mites or rust mites are present, or switch to other alternatives.
4. **Ring Rot Disease**
This fungal disease affects branches and fruits. It enters through wounds or directly. Conditions like heavy rain, flooding, and poor drainage favor its spread. Symptoms include circular, wheel-like lesions on fruits, with gray centers. On twigs, peeling reveals a yellow liquid. Fruit pedicles may show yellow dots, and the sponge layer turns brown. Infected fruits dry out quickly, emit a bad smell, and die within 3–6 days.
To manage the disease, spray copper ammonium around new spring shoots (0.5–3 cm) or use thiophanate-methyl 500 times. Spray 1–2 times in early March, late April, mid-May, and mid-August. Apply thiophanate-methyl 500 times monthly to fruits.
5. **Scab Disease**
Scab disease affects leaves, branches, and fruits. Caused by fungi, it enters through wounds or directly. It thrives in temperatures between 20°C and 210°C, with high humidity. Symptoms include raised, blister-like spots on leaves, which cause distortion and twisting.
Prevention includes applying copper ammonium or 0.5% Bordeaux mixture during the early growth stages of young leaves and fruits.
6. **Sooty Mold**
Sooty mold affects leaves and branches. It is caused by various fungi that grow on excretions from aphids, mites, and whiteflies. Heavy pest infestations can lead to the spread of spores and cause plant diseases. High humidity favors the disease. Symptoms include a dark brown mold layer on leaves, shoots, and fruits, which eventually turns black and covers the surface. The fungus only grows on the surface and does not penetrate the plant tissue.
Control methods include:
(1) Controlling aphids, mites, and whiteflies is essential.
(2) Spray 0.3–0.5% Bordeaux mixture, thiophanate-methyl chloride 700 times, or 50% carbendazim 500 times.
(3) Prune moderately to improve air circulation and light penetration inside the canopy.
