Occurrence Patterns and Control Methods of Potato Blackleg
Symptoms Potato blackleg is a bacterial disease that infects vascular bundle tissue and can infect potato stems and tubers. It can occur from seed potato sprouting to the late growth stage, and is most prevalent at the seedling stage. Most diseased plants lose water and droop, the leaf color remains unchanged, the whole plant wilts, and the blackleg portion is mostly softened and rotted. The color of the diseased part is yellowish-brown, light brown, dark brown, or pale green. The vascular bundles inside the stem and the vascular bundles of the underground stem basically become discolored in a ring shape. The junction of the stem base and the mother tuber first turns black, then spreads toward the area near the soil surface, forming blackleg. When humidity is high, the blackleg can rise to 3.

How to prevent and control potato blackleg? A detailed guide to practical measures
[Prevention and control measures] (1) Implement quarantine, strictly prohibit the transfer of seed potatoes from diseased areas, and prevent further spread. (2) Select disease-resistant, high-yielding varieties suited to the local area to reduce damage. (3) Select and retain disease-free seed potatoes. In the south, use autumn planting for seed production, choosing moderately sized small tubers to use directly as seed potatoes; in northern potato regions, establish disease-free seed fields, and in severely affected areas adopt whole-tuber sowing to avoid transmission by cutting knives. True seedlings, or disease-free stem cuttings for raising seedlings, may also be used, planting disease-free seed potatoes to reduce primary infection sources. (4) Choose sandy loam and high, dry land for planting, prepare the soil finely, drain and irrigate in a timely manner, and fertilize
