Common diseases and pests of Scutellaria barbata and their control

Common symptoms and prevention of Scutellaria barbata

The pathogens mostly invade the base of the rhizomes of seedlings from the surface soil. When the plants are infected, the diseased parts rot and the seedlings fall over. If the seedling tissue begins to lignify, it will die immediately. The affected part is sunken and constricted, and appears dark brown. When it is moist, white mycelium grows from the diseased area. When the disease occurs seriously, a large number of seedlings die.

Prevention and control methods: Keep the seedlings dry within 10 to 20 days after they emerge from the soil. Soil disinfection should be carried out in the early stage of seedling disease. Mix 4 wettable powders in equal amounts and spread on the soil.
