Wheat stem-based rot is a typical soil-borne disease in wheat production and can also be transmitted through seeds.病原体的孢子可以在冬季生存，并在适当的温度后在土壤表面发芽。病原体通常从根和根茎的连接处侵入，感染小麦的主茎和耕种茎，然后膨胀到小麦茎的底部。 This disease has the characteristics of multiple infections and is a fungal disease.

The obvious feature after the early harm is that the roots are brown, and the 1-2 sections of the roots are brown, and in severe cases it turns dark brown and begins to die. Red or white mold may appear on wheat roots with high humidity or mid-to-late stages. Symptoms vary according to climatic conditions: in arid and semi-arid areas, stem base rot and root rot are often caused; in humid areas, in addition to the above symptoms, leaf spots, stem dryness, and ear neck dryness. When seedlings are invaded, the bud sheaths and roots turn brown or even rot. In severe cases, young buds cannot be unearthed and die; during the tillering stage, brown spots occur in the rhizomes, and brown rot in the leaf sheaths, which can cause the death of the seedlings. During the planting period, the black-brown fusiform lesions are initially produced on the leaves or leaf sheaths, and then expanded into oval or irregular brown spots, with a center of gray to light brown and not obvious at the edges. During the humid and rainy air, black mold occurs on the lesions, which are easy to wipe off with your hands. Lesions on the leaf sheath can also cause disease of the stem nodes. When the spikes occur, some spikelets will become ill, and the spikelet stems and embers will turn brown. When the humidity is high, black mold will also appear on the surface of the lesions, and sometimes the spikes will become dry or the spikes will fall off. When the seed is injured, the embryo tip of the diseased grain is black, and in severe cases the whole embryo is black; root rot can also occur in the ventral and dorsal or ventral groove of the endosperm, with the lesions spindle-shaped, brown at the edges and white at the center. These seeds are called \”spotted grains\”.

Prevention and treatment methods: 10-12 grams of 80% pivalazole water dispersion granules or 200 grams per liter of 50-65 ml of fluorazole hydroxylamine suspension agent; 20-25 ml of 24% thiofuramide suspension agent or 50-60 ml of 18.7% propionazole · acaffinate suspension agent can also be used, and 30-40 ml of 17% zolithium ether · fluorazole suspension emulsion can be used to spray the base of wheat stems with 60-70 liters of water to treat diseases such as wheat striatum blight. If there is a serious plot, spray it again after 7-10 days apart.
