Fortalecimiento del Control de Plagas y Enfermedades en Plántulas para Sentar una Base Sólida para la Cosecha de Colza de Invierno

Since the middle and late September this year, the combined impact of the "West China Autumn Rain" and autumn floods has led to persistently high soil moisture in the main winter rape - producing areas such as Southwest China and the middle and lower reaches of the Yangtze River. This has created favorable conditions for the occurrence and spread of various pests and diseases, including seedling blight (root rot), damping - off disease, and cabbage leaf beetle. The seedling stage is a crucial foundation - laying period for the growth and development of winter rape, and the effectiveness of pest and disease control directly affects the subsequent growth, yield, and quality of the crop. To accurately respond to the current pest and disease control situation and consolidate the foundation for a good rape harvest, the National Agricultural Technology Extension and Service Center has specially formulated and issued the Technical Guidance on Pest and Disease Control for Autumn - sown Winter Rape Seedlings in 2025, providing scientific control guidance for growers in the producing areas.
