Tóm tắt

The leaf blight disease from Allium chinense caused by Xanthomonas spp. has led to significant economic losses for farmers of this crop in Dong Thap province. This study aims to evaluate the pathogenicity of Xanthomonas spp. on Allium chinense and Allium sativum (garlic) and assess the effectiveness of some antibiotics and chemical compounds in controlling this pathogen. The results indicate that the bacteria responsible for leaf blight on Allium chinense can also infect garlic, causing characteristic symptoms such as small, pale yellow lesions at the leaf tips or along the veins. These lesions subsequently expand, leading to leaf yellowing, browning, and necrosis. Additionally, in vitro experiments revealed that oxolinic acid 20% exhibited the highest antibacterial efficacy, with an inhibition zone diameter of 36.3 mm after a 72 hour test. These findings suggest that oxolinic acid has strong potential for controlling the leaf blight pathogen in Allium chinense and Allium sativum (garlic).
