Green mold () and blue mold () are among the most economically impactful post-harvest diseases of citrus fruit worldwide. Post-harvest citrus diseases are largely controlled with synthetic fungicides such as pyrimethanil, imazalil, fludioxonil, and thiabendazole. Due to their toxic effects, prolonged and excessive application of these fungicides is gradually restricted in favor of safe and more eco-friendly alternatives. This review comprehensively describes alternative methods for the control of and : (a) antagonistic micro-organisms, (b) plant extracts and essential oils, (c) biofungicides, (d) chitosan and chitosan-based citrus coatings, (e) heat treatments, (f) ionizing and non-ionizing irradiations, (g) food additives, and (h) synthetic elicitors. Integrating multiple approaches such as the application of biocontrol agents with food additives or heat treatments have overcome some drawbacks to single treatments. In addition, integrating treatment approaches could produce an additive or synergistic effect on controlling both molds for a satisfactory level of disease reduction in post-harvest citrus. Further research is warranted on plant resistance and fruit-pathogen interactions to develop safer strategies for the sustainable control of and in citrus.
绿霉病()和青霉病()是全球范围内对柑橘类水果采后经济影响最大的病害之一。采后柑橘病害主要通过使用嘧霉胺、抑霉唑、咯菌腈和噻菌灵等合成杀菌剂来控制。由于这些杀菌剂的毒性作用,其长期过量使用逐渐受到限制,转而青睐安全且更环保的替代品。本综述全面描述了控制和的替代方法:(a)拮抗微生物,(b)植物提取物和精油,(c)生物杀菌剂,(d)壳聚糖及基于壳聚糖的柑橘涂层,(e)热处理,(f)电离和非电离辐射,(g)食品添加剂,以及(h)合成激发子。将生物防治剂与食品添加剂或热处理等多种方法结合使用,克服了单一处理方法的一些缺点。此外,整合处理方法在控制两种霉菌方面可能产生累加或协同效应,从而使采后柑橘的病害减少达到令人满意的水平。有必要进一步研究植物抗性和果实 - 病原体相互作用,以制定更安全的策略,实现柑橘中、可持续控制。
