Symptoms The basal stems and roots of the diseased plants are gray-brown streaks. The main roots and lateral roots, which are 3 to 4 cm long and the surface of the disease are heavy, turn dark grayish brown, and some hair roots have gray-brown streaks.
Pathogen Thielaviopsisbasicola (Berk. et Br.) Ferr. Rhizoctonia is a fungus belonging to the fungus. On the CA plate, colonies were grayish black, aerial hyphae were lush, pale in PDA, light gray, and the colony edge had a grayish white band. Conidiophores were bottle-shaped, with 49.8-139.4 microns in length, 7.4-12.46 microns in width at the base, and 3.7-4.9 microns in width at the top port. Endogenous conidia are colorless, cylindrical, 19.9 to 22.44.9 to 7.4 μm in size, and chlamydospores are produced on the apical or lateral side of a dry mycelium, with 1 to 2 cells at the base. Wall thickness, cylindrical, apical cell capsules, size 9.9 to 14.97.4 to 9.9 microns.
Pathogens and Pathogens The pathogenic bacteria overwintered in the soil with the diseased body, and the first infestation and reinfestation occurred in Tianwen in the following year. In the field with 111 propagules per gram of soil, it is possible to see sub-populins and chlamydospore.
Control methods (1) Selection of disease-resistant varieties, such as Ganjing's Gongjing selection, hemp beans, adzuki bean 60,704. (2) Application of enzyme composted compost and fully decomposed organic fertilizer to reduce the amount of chemical fertilizers. (3) seed dressing with 0.25% seed weight of 20% triadimefol EC, also called seed dressing with 0.2% of 75% chlorothalonil or 50% carbendazim WP, with certain effect . The bacterium is sensitive to benzomidazole fungicides such as carbendazim.
