One of the main problems that fruit health has gone through in recent years is the problematic eradication of their fungal pathogens during crops or the post-harvest stage. This concerns the whole world because it represents huge production losses, fruit export restrictions, and consumer distrust. Consequently, new alternatives are sought to avoid the increasing use of fungicides that cause important damage to fruit consumers and the environment. One of the alternatives to solve this problem could be exploring plants and their active compounds applied to the treatment of fruit health.
This article describes peach production worldwide and particularly in Argentina, in addition to the main fungal rot that causes the greatest economic losses. Furthermore, experimental in-vitro studies of 69 extracts obtained from 18 plants growing in the central region of Argentina were displayed against the devastating fungus Monilinia fructicola, which greatly affects stone fruits. A simple and effective method developed in agar plate was applied to evaluate a large number of samples in a short time.
The results showed that approximately 36% of the samples tested were strongly active against this pathogen, 12% were moderately active, and 52% demonstrated to be inactive.
These findings support the possible use of natural products for fruit health and the importance of deepening in this field of science.
近年来，水果健康面临的主要问题之一是在作物或收获后阶段难以彻底消除真菌病原体。这关系到全世界，因为它代表着巨大的生产损失、水果出口限制和消费者的不信任。因此，人们正在寻找新的替代品来避免杀菌剂的使用不断增加，因为杀菌剂会对水果消费者和环境造成重大损害。解决这个问题的一种替代方法可能是探索植物及其活性化合物在水果健康处理中的应用。
本文描述了全世界范围内的桃生产情况，特别是在阿根廷的情况，以及造成最大经济损失的主要真菌腐烂病。此外，对从阿根廷中部地区生长的 18 种植物中获得的 69 种提取物进行了体外实验研究，以对抗严重影响核果的毁灭性真菌 Monilinia fructicola。应用琼脂平板上开发的简单而有效的方法可以在短时间内评估大量样品。
结果表明，约 36%的测试样品对该病原体具有很强的活性，12%的样品具有中度活性，52%的样品无活性。
这些发现支持了天然产品在水果健康方面的可能应用，以及深化这一科学领域的重要性。
