The major diseases recently occurring in the peach and plum fruits in the northern Guangxi region are anthracnose, brown rot, and bacterial perforation. Please check with the farmers to prevent and treat these diseases. Anthracnose: The main damage fruit, but also infect new shoots, leaves. Young fruit is infected, dark brown fruit surface, developmental stagnation; fruit enlargement disease, the fruit surface was light brown water-stained lesions at the beginning of the fruit surface, with the fruit enlargement, lesions expand and become red-brown, round or oval depression spots, And there are obvious concentric rings and wrinkles. When the humidity is high, the diseased part produces orange-red spots. Brown rot: The main damage is fruits, flowers, leaves and shoots. The diseased fruit begins to produce brown round lesions on the fruit surface. The diseased fruit flesh turns brown and decays. It is initially in a concentric ring arrangement. The surface of the lesion produces a yellowish-white or gray-brown villus-like moldy layer. The diseased fruit in the later stage is completely rotted and lost. The water shrinks and forms a stiff fruit. Bacterial perforation disease: mainly damage the leaves, but also infect the fruit and shoots. The leaves were infected, and at the beginning of the leaf veins near the leaf veins, there were spots of light brown water stains. After the lesions were enlarged, there were water-stained yellow-green halo rings. Finally, the lesions were dry and the center tissue of the lesions fell off and perforation was formed; the fruit was infected. In the beginning, brown water stains were small round spots, and small cracks often occurred on or around the lesions during drying. The disease was limited to the epidermis of the fruit to form a flower face. Prevention and control opinions: 1. Strengthen the cultivation and management, and increase the resistance to tree diseases. Pay attention to the ventilation of the orchard and drainage, increase organic fertilizer and phosphorus and potassium fertilizers. 2, remove bacteria source. Combine pruning in the late autumn and early winter, completely clear the sick branches and diseased fruits in the garden, and burn them centrally or deeply. 3, chemical control. Focus on the use of drugs during budding, post-flowering, and early onset. Anthracnose and brown rot can be used 800 times as much as 70% Caso Thiophanate, and 72% as Streptomycin Sulfate can be used as bacterial perforation.
