Comprehensive control of wheat scab in Yushan District
Starting from the wheat production practice in Yushan District,Ma'anshan,Anhui Province,the causes,main disease symptom,hazards,and prevention and control measures were summarized and analyzed of scab in this crop.Wheat scab is one of the important diseases affecting wheat production caused by Fusarium spp.,and is a typical climatic disease.The research area belongs to the transitional zone of the northern subtropical monsoon,and the climatic conditions are favorable for the infection of Fusarium;at the same time,the high-amount of fungal sources in the field,weak resistance of planting varieties,improper cultivation methods and management can exacerbate the occurrence and spread of the disease to a certain extent.This disease can cause a large-scale reduction in wheat yield,and the toxins in the diseased ears can also cause harm to humans and livestock.Based on this,the strategies were proposed to establish a monitoring and early warning system to timely grasp the dynamic occurrence of diseases;improve cultivation and management techniques such as timely and appropriate sowing,scientific fertilization,and field management;standardize straw returning,application of base fertilizer,and introduction of biological control bacteria to reduce the base of pathogenic bacteria in the field;breeding and planting disease resistant varieties using molecular markers and other techniques;adopt scientific chemical prevention and control measures such as seed mixing with pesticides,appropriate timing of medication,alternating and rotating medication,and selecting suitable machinery;timely harvesting,drying,and storage,as well as strengthening collection and storage management for preventing and controlling wheat scab,provides references for comprehensive prevention and control of scab in wheat production in related area.
