Abstract

Postharvest diseases in fruits result in significant losses in the agricultural sector. Among these, green mould, caused by Penicillium digitatum, poses a considerable threat to citrus fruits. This study evaluated the potential of Bacillus amyloliquefaciens strain TV-17C as a biological control agent for managing green mould in oranges. Various concentrations of TV-17C in aqueous suspension were applied to naturally infected orange fruits in the packinghouse at two locations (Hatay and Mersin provinces), while the chemical fungicide fludioxonil 230 SC served as a positive control. The application of B. amyloliquefaciens TV-17C at the dosage of 250 mL 100 L−1 reduced green mould incidence by 90.3% and 89.8% in Hatay and Mersin provinces, respectively. Similarly, fludioxonil 230 SC displayed an efficacy of 91.4% in reducing disease incidence. In summary, this study underscores the potential of B. amyloliquefaciens TV-17C as an efficient biocontrol agent against green mould in oranges. Moreover, a positive correlation between higher concentrations and enhanced efficacy was evident. These findings hold promise for the adoption of sustainable disease management practices in the postharvest citrus industry.

评估淀粉芽孢杆菌 TV-17C 作为一种潜在的生物控制剂对柑橘采后青霉的控制作用
水果采后病害给农业部门造成重大损失。其中,由青霉(Penicillium digitatum)引起的绿霉病对柑橘类水果构成了相当大的威胁。本研究评估了淀粉芽孢杆菌(Bacillus amyloliquefaciens)菌株 TV-17C 作为生物防治剂防治柑橘绿霉病的潜力。在两个地点(哈塔伊省和梅尔辛省)的包装车间,将不同浓度的 TV-17C 水悬浮液施用到自然感染的橘子果实上,同时将化学杀菌剂氟啶氧菌酯 230 SC 作为阳性对照。在哈塔伊省和梅尔辛省,以 250 mL 100 L-1 的剂量施用淀粉芽孢杆菌 TV-17C 后,绿色霉菌发病率分别降低了 90.3% 和 89.8%。同样,氟啶虫酰胺 230 SC 在降低病害发生率方面的功效为 91.4%。总之,本研究强调了淀粉芽孢杆菌 TV-17C 作为一种高效生物防治剂防治柑橘绿霉病的潜力。此外,浓度越高,药效越强,两者之间存在明显的正相关关系。这些发现为柑橘采后行业采用可持续的病害管理方法带来了希望。

期刊介绍: Journal of Phytopathology publishes original and review articles on all scientific aspects of applied phytopathology in agricultural and horticultural crops. Preference is given to contributions improving our understanding of the biotic and abiotic determinants of plant diseases, including epidemics and damage potential, as a basis for innovative disease management, modelling and forecasting. This includes practical aspects and the development of methods for disease diagnosis as well as infection bioassays. Studies at the population, organism, physiological, biochemical and molecular genetic level are welcome. The journal scope comprises the pathology and epidemiology of plant diseases caused by microbial pathogens, viruses and nematodes. Accepted papers should advance our conceptual knowledge of plant diseases, rather than presenting descriptive or screening data unrelated to phytopathological mechanisms or functions. Results from unrepeated experimental conditions or data with no or inappropriate statistical processing will not be considered. Authors are encouraged to look at past issues to ensure adherence to the standards of the journal.
