Abstract

This study was carried out to evaluate the in vitro antifungal potential of natural extracts from marc, spontaneous flora plants, and synthetic pesticides. The biological control of pathogens is a modern alternative because does not represent a danger to humans and the environment. Thus, natural alternatives with a fungistatic or fungicidal effect on the pathogen Botrytis cinerea were identified. The results of the in vitro tests clearly indicated a significant inhibitory percentage on the growth rate of the Botrytis cinerea rot mycelium (62.38%), when was used the extract obtained from the Cabernet Sauvignon marc at a concentration of 15%, compared to the other two natural extracts used (Salvia officinalis and Chelidonium majus), where the diameter of the colonies recorded values close to the untreated control variant. Regarding the effect of the synthetic pesticides studied, the best results were recorded with fosetyl-aluminum where a 100% inhibition percentage on the Botrytis cinerea pathogen was recorded.

评估天然提取物和合成杀虫剂对灰葡萄孢菌生长和发育的体外抗真菌潜力

这项研究旨在评估从自生植物中提取的天然提取物和合成杀虫剂的体外抗真菌潜力。病原体的生物防治是一种现代替代方法，因为它不会对人类和环境造成危害。因此，我们确定了对病原体 Botrytis cinerea 具有抑菌或杀菌作用的天然替代品。体外试验的结果清楚地表明，与使用的其他两种天然提取物（丹参和大叶黄杨）相比，使用浓度为 15%的赤霞珠萃取物对灰葡萄孢腐菌丝的生长率有明显的抑制作用（62.38%），菌落直径的记录值接近未处理的对照变体。至于所研究的合成杀虫剂的效果，使用磷酰铝的效果最好，对灰葡萄孢病原体的抑制率达到 100%。
