Inhibitory Effect of CUSTOS, a Formulated Allium-Based Extract, on the Growth of Some Selected Plant Pathogens

Plants are in intimate association with a great diversity of pathogenic and mutualistic microbes that use host plants for proliferation. Plants, turn, have evolved mechanisms contingent upon their innate immune system to resist perceived biotic stresses. The objective this work is determine the antimicrobial properties an allium-based formulation named CUSTOS on growth plant microorganisms such as fungi, oomycetes, bacteria. Two anthracnose-related species fungal genus Colletotrichum, Colletotrichum gloeosporioides, oomycete Phytophthora cactorum, bacterium Xanthomonas fragariae associated strawberry were tested vitro. Furthermore, two fungi Alternaria dauci Botrytis cinerea, carrot plants, planta. inhibited all pathogens tested. We found both curative preventive planta treatments cinerea carrots. differential expression levels PR 10 genes correlated magnitude infection. also field application results reduction fruits stored under refrigeration. In summary, may induce pathogen resistance fruit vegetable can be used against rotting disease.
