Pest Control
Purple cabbage is generally resistant to diseases when properly managed, making it easy to produce high-quality, pollution-free vegetables that can even be eaten raw. However, during the seedling stage, high humidity may lead to issues like damping-off and downy mildew. These can be effectively controlled using fungicides such as Yunsheng, Dasheng, Carbendazim, Xinluling, and Anke. In terms of insect pests, aphids, diamondback moths, and cabbage worms are the most common threats. For aphid control, spraying with 50% Imidacloprid WP at a dilution of 2000–3000 times or Scorpion at 1000–1500 times is recommended. To manage cabbage worms, Anji Microemulsion diluted 1000–1500 times or Obtained at 26.7–33.3 ml per mu can be applied. Diamondback moths can be controlled by spraying 1000–1500 times dilution of a suitable insecticide or using a 1000-time dilution for effective results.Timely Harvest
Purple cabbage has good storage and transportation qualities, allowing for multiple harvests based on maturity. The yield per mu can reach 3000–4000 kg. When harvesting, it's advisable to leave 2–3 outer leaves intact and store the cabbages in a cool, dry place for up to 50 days, ensuring freshness and quality.(Agronomist, Chengdu Agricultural Quality Monitoring Center)
