Abstract: To explore the botanical agents to prevent and control apple ring spot disease,the inhibitory of the four common of Allium plant extracts,on the hypha growth of Botryosphaeria berengriana were tested.On this basis,the metabolites of the four Allium plants,Chinese leek,garlic,onions and welsh onion,were analyzed by metabolomics methods,and the suppressive effects of the main components of the four Allium plants on the mycelial growth of B.berengriana and the incidence of the apple ring disease on the apple fruits were also determined.The results showed that in the whole experiment period the inhibition of four Allium plant extracts(1×)on the growth of mycelia of B.berengriana was as high as 100%.78 metabolites were detected in the four Allium plants.Among them,the three main components,pyroglutamic acid,phosphoric acid and citric acid,inhibted the growth of mycelia of B.berengriana by 29.10% to 100.00%,and inhibited the incidence of ring disease on apple fruit caused by B.berengriana by 44.38% to 91.45%.The results of this study laid a theoretical foundation for further understanding and developing the antimicrobial components in Allium,and provided a potential way for the prevention and treatment of apple ring disease.

Key words: Allium spp., Apple ring diease, Pyroglutamic acid, Phosphoric acid, Citric acid
