Methods and Technical Key Points for the Prevention and Control of Licorice Pests and Diseases
The main diseases of licorice are rust, powdery mildew and brown spot. Licorice rust mainly damages the leaves and tender stems of the plant; the back of infected leaves produces yellow-brown blister-like lesions on one side, and after the epidermis ruptures, brown powder is released. Prevention and control method: burn the leaves of diseased plants. In the early stage of the disease, treat with a 1000-fold dilution of Fenxiuning; you can also use 0.3 degrees Baume lime sulfur mixture, or a 500-fold dilution of 65% wettable zineb, or a 200-fold dilution of dithianon sodium for spray control, spraying once every 7 to 10 days, and 2 to 3 consecutive sprays are sufficient. Licorice brown spot is also called

Biological agents developed for pest and disease control throughout the goji growing season
With the creation of 4 compound pure biological agents formulated by the "Research on Biological Control Technology for Major Goji Pests and Diseases" team at the Institute of Plant Protection of the Ningxia Academy of Agriculture and Forestry Sciences, the pests and diseases constraining the development of Ningxia's goji industry have finally met their greatest "natural enemy." The use of these agents will achieve biological control of pests and diseases throughout the entire goji growing season, not only reducing the number of control applications but also improving goji quality. Goji is a traditional medicinal herb cultivated in Ningxia and is also a leading industry designated by the autonomous region's Party committee and government. However, the occurrence of goji pests and diseases is extremely complex,
