The Italian garlic ecotype “Vessalico” possesses distinct characteristics compared to its French parent cultivars Messidor and Messidrôme, used for sowing, as well as other ecotypes in neighboring regions. However, due to the lack of a standardized seed supply method and cultivation protocol among farmers in the Vessalico area, a need to identify garlic products that align with the Vessalico ecotype arises. In this study, an NMR-based approach followed by multivariate analysis to analyze the chemical composition of Vessalico garlic sourced from 17 different farms, along with its two French parent cultivars, was employed. Self-organizing maps allowed to identify a homogeneous subset of representative samples of the Vessalico ecotype. Through the OPLS-DA model, the most discriminant metabolites based on values of VIP (Variable Influence on Projections) were selected. Among them, S-allylcysteine emerged as a potential marker for distinguishing the Vessalico garlic from the French parent cultivars by NMR screening. Additionally, to promote sustainable agricultural practices, the potential of Vessalico garlic extracts and its main components as agrochemicals against Xanthomonas campestris pv. campestris, responsible for black rot disease, was explored. The crude extract exhibited a MIC of 125 μg/mL, and allicin demonstrated the highest activity among the tested compounds (MIC value of 31.25 μg/mL).

The development of antibiotic alternatives is an important issue for controlling plant-pathogenic bacterial disease due to the development of resistance and limited use guidelines for antibacterial pesticides in crop fields. Geraniol, thymol, and ovanillin were known to have antibacterial activity; however, the antibacterial activity and the disease control efficacy against Erwinia carotovora were not reported in the crop. In this research, the minimal inhibitory concentration (MIC) and the disease control efficacy of geraniol, thymol, and o-vanillin were investigated as well as the residues in cabbage. MICs of geraniol, thymol, and o-vanillin were 125-250 µg mL 1 , and MIC of a mixture of the three compounds was 93.8 µg mL 1 against E. carotovora. The fractional inhibitory concentration index of the mixture agent was 0.625, and it presented an additive effect. The disease protection efficacy of the mixture agent was 72.7% for bacterial soft rot after twice application on 340 mg L 1 . The initial residues of geraniol, thymol, and o-vanillin were 0.66, 3.72, and 0.28 mg kg 1 , respectively; however, 50% of dissipation times for all three compounds were below a day.
