Conditions for Fusarium head blight occurrence and prevention and control measures in Fengyang County

The occurrence conditions of wheat Fusarium head blight were analyzed in Fengyang, Anhui Province, based on local climatic conditions, and integrated management strategies for the disease were proposed.The study area has an average annual temperature of approximately 14.8 ℃ and an average annual rainfall of 912 mm, with relative humidity ranging between 75% and 80%. The climate is mild with distinct seasonal variations. The soils are predominantly cinnamon, paddy, and sandy loams, characterized by deep layers, good structure, and abundant organic matter, all providing favorable conditions for the occurrence of wheat Fusarium head blight. Furthermore, crop rotation patterns such as maize-wheat and rice-wheat provide suitable overwintering conditions for the pathogen, leading to the annual accumulation of inoculum and increasing the risk of disease outbreaks. In response to the above conditions, the following control measures should be taken: to reduce the accumulation of pathogen sources, the rotation of crops should be adjusted and the treatment of crop residues optimized; to address factors such as temperature, humidity and soil, agricultural measures such as selecting resistant varieties and optimizing water and fertilizer management to reduce field humidity; employing biochemical controls using plant growth regulators and immune inducers; and applying chemical controls, using high efficacy agents like prothioconazole while alternating modes of action to delay resistance development. Post-harvest, rapid drying or sunning of grains to safe moisture levels and enhanced storage management are essential to prevent mold and toxin accumulation, ensuring food safety. Future efforts should focus on leveraging technologies such as gene cloning, functional molecular markers, and remote sensing monitoring to strengthen the breeding of resistant varieties and improve disease surveillance. These advances will enhance the control of wheat scab and promote the sustainable development of the related industry.
