In the last years, our research has focused on the study of brown rot on stone fruit caused by Monilinia spp. in the ‘Valle del Ebro’ (Spain). The epidemiology of this disease was thoroughly investigated in the field and one of the main outcomes was the development of a prediction model that indicates the risk of infection. Furthermore, the epidemiology was also studied in the postharvest phase, providing a lot of information regarding the relevance of the main postharvest handling operations, the identification of fungal population in packing houses, the fruit infection risks and the influence of temperature and humidity on conidia survival.

Additionally, many efforts have been orientated to the development of control strategies for both pre and postharvest periods. Traditionally, chemical fungicides have been used to preserve fruit quality over extended periods of storage or transportation. However, the growing public concern over health and environmental hazards associated with high levels of pesticides has resulted in restrictions imposed by legislation and also by distribution companies. In this context, our main goal has been the development of environmentally friendly alternative strategies to synthetic fungicides in order to control brown rot on stone fruit. Although many studies have demonstrated the efficacy of these alternative treatments, only a few of them are currently applied under commercial conditions. Biocontrol agents, natural compounds from different origins and physical means are the main approaches which have been studied, with different success levels. There are several reasons for the limited success of these treatments, such as the inconsistency of results, variability of the efficacy under commercial conditions, low persistence, a narrow spectrum range of activity, the difficulties in developing a shelf-stable formulated product that retains efficacy (in the case of biocontrol agents), and economical and regulatory limitations. Generally, it is accepted that the combination of different strategies is necessary to improve the control of postharvest diseases and that the real solution needs to integrate different tools to achieve satisfactory disease control. The aim of this review is to describe the main efforts conducted by our research group regarding the control of brown rot on stone fruit, from epidemiology studies to the development of effective control strategies.

核果褐腐病:从流行病学研究到制定有效控制策略

在过去的几年中,我们的研究主要集中在由Monilinia spp引起的核果褐腐病的研究。在'Valle del Ebro'(西班牙)。在该领域对这种疾病的流行病学进行了彻底调查,主要成果之一是开发了一种预测模型,表明感染风险。此外,还对采后阶段的流行病学进行了研究,提供了大量关于主要采后处理操作的相关性、包装车间真菌种群的鉴定、果实感染风险以及温度和湿度对分生孢子存活的影响的信息。 .

此外,许多努力都集中在制定收获前和收获后的控制策略。传统上,化学杀菌剂已被用于在长时间的储存或运输过程中保持水果质量。然而,公众对与高浓度杀虫剂相关的健康和环境危害日益关注,导致立法和分销公司施加限制。在这种情况下,我们的主要目标是开发合成杀菌剂的环保替代策略,以控制核果褐腐病。尽管许多研究已经证明了这些替代疗法的功效,但目前只有少数在商业条件下应用。生物防治剂,来自不同来源和物理手段的天然化合物是已研究的主要方法,具有不同的成功水平。这些治疗方法的成功有限有几个原因,例如结果的不一致、商业条件下疗效的可变性、持久性低、活性谱范围窄、难以开发保持疗效的货架稳定的配方产品(在生物防治剂的情况下),以及经济和监管限制。一般认为,不同策略的组合对于改善采后疾病的控制是必要的,而真正的解决方案需要整合不同的工具以实现令人满意的疾病控制。
