Salvia miltiorrhiza Pest Management
Salvia miltiorrhiza, commonly known as Danshen, is a popular medicinal herb that is susceptible to various pests and diseases. To ensure healthy growth and high-quality yield, it's essential to understand and manage these issues effectively. Here are the main pests and diseases affecting Salvia miltiorrhiza: (1) Root Rot: This fungal disease is common in poorly drained soils. To prevent it, choose a field with good drainage and avoid waterlogging, especially during the rainy season. At the early stage of infection, drench the roots with a 50% carbendazim solution diluted at a ratio of 1:1000. Proper soil management and crop rotation can also reduce the risk of root rot. (2) Leaf Spot: This disease causes brown or black spots on the leaves. To control it, apply a Bordeaux mixture (1:1:150) when symptoms first appear. Regular monitoring and timely application of fungicides can help prevent the spread of the disease. (3) Ground Tiger (Cutworms): These pests often attack young plants at night. They can be manually collected in the early morning or controlled using poisoned baits. A mixture of 100 grams of sautéed rapeseed cake and 90% trichlorfon crystals per acre is effective for controlling cutworm infestations. (4) Cockroaches: These pests tend to infest the field in the fall. To manage them, you can pour a diluted solution of 90% trichlorfon (1000-1500 times) around the base of the plants. Manual removal is also an option, especially in smaller fields. (5) Root-knot Nematodes: These microscopic worms damage the roots and hinder plant growth. The best way to prevent this is through crop rotation, avoiding planting Salvia miltiorrhiza in the same area consecutively. It's also important to use disease-free seedlings and avoid planting in areas where previous crops were affected by nematodes. Harvesting of Salvia miltiorrhiza typically takes place from late November to the end of December. When harvesting, carefully dig up the entire plant without cutting the roots. Gently shake off the soil, trim the roots, and remove the top portion. The roots should then be dried thoroughly to preserve their quality. Freshly harvested roots must be dried quickly to avoid freezing or decay, ensuring they retain their medicinal properties. Soybean Lecithin oil is a byproduct of soybean oil production.
