Anthrax is a serious plant disease that primarily affects leaves, branches, and fruits, as well as seedlings, flowers, and fruit stems. The symptoms on the leaves typically appear at the edges or tips, forming round or irregular lesions that are dark brown in color with a gray-brown center. When dry, these spots turn gray, and they often contain numerous small black dots. Under wet conditions, orange-red viscous droplets may emerge from these spots. In cases of prolonged rainfall, an "acute type" of lesion may develop—starting as a light blue or bluish spot, resembling a burn, then rapidly expanding into water-soaked, unclear, and corrugated lesions. These can lead to leaf drop within days.
On branches, infections usually begin at axillary buds or wounds near the petiole base, starting as small, light brown oval lesions that later grow into long rhomboid shapes. As the disease progresses, the branch may die back, with leaves curling and drying without falling. In severe cases, especially after heavy rains, the shoot tip may suddenly become scalded, leading to rapid wilting and the appearance of small orange liquid spots.
For seedlings, the infection commonly starts 7–10 cm above the ground or at the grafting site, resulting in dark brown spots that can cause the top of the stem to die and branches to wither. In the flower stage, the disease often attacks the pistil, causing brown rot and premature flower drop.
Fruit stems show pale yellow discoloration that turns brown and dry, leading to fruit drop or desiccation. Fruits may exhibit two types of damage: dry pods and fruit rot. Dry pods have distinct, round, yellow-brown to dark brown lesions with black spots, while fruit rot occurs in humid conditions, beginning at the pedicle or fruit waist, leading to browning and decay.
Prevention and control measures focus on strengthening cultivation practices, such as improving soil quality, applying organic and mineral fertilizers, ensuring proper drainage, pruning, and controlling pests. These efforts help enhance tree vigor and reduce disease incidence.
Ulcer disease is characterized by oily yellow spots on the underside of leaves, followed by raised, corky lesions. A volcano-like crack appears in the center with a yellow halo. On branches and fruits, similar lesions occur without the halo. In advanced stages, leaves fall, branches die back, and fruits drop early. Control involves strict phytosanitary measures, including quarantine of plants and removal of infected areas. Spraying with antibiotics like streptomycin and fungicides like Ye Qingshuang is also recommended, along with managing insect vectors.
Scab is a major disease in grapefruit, affecting spring and autumn shoots, young leaves, flowers, and fruits. It causes leaf and fruit drop, deformities, and reduced quality. Control includes chemical sprays like Bordeaux mixture, carbendazim, and thiophanate-methyl, applied during critical growth stages. Pruning, sanitation, and using disease-free planting material are also essential.
Resin disease damages stems, leaves, and fruits, often leading to branch death. Prevention involves improving tree health through proper fertilization, soil management, and pruning. Chemical treatments like Bordeaux mixture and carbendazim are used for protection, especially during vulnerable growth stages.
Maculopathy causes yellowish spots on the underside of leaves, which develop into dark brown patches. On the upper side, irregular yellow lesions form, leading to leaf drop and reduced yield. Infected fruits show red-brown spots, lowering their commercial value. Control methods include balanced fertilization, garden sanitation, and timely spraying with Bordeaux mixture, copper-based products, and other effective fungicides.
