Anthracnose caused by Colletotrichum acutatum, is a major disease of the cultivated strawberry (Fragaria × ananassa Duch.) in Europe. Control measures must begin at planting and in nurseries and depend on cultural practices, the use of anthracnose free plants, the use of resistant cultivars and by applying protective fungicides. Most of the fungicides registered for use on strawberries have a limited efficacy against anthracnose pathogens. The search of alternatives to the use of chemicals to control plant diseases is a goal in the usage of biological methods. Various compounds obtained from plants have been assessed for their ability to control C. acutatum under laboratory conditions. In vitro assays showed that Cinnamomun extract was fungistatic at the lowest dose. One such approach to the control of plant disease is through the induction and enhancement of the plant’s own defence mechanism, which does not involve the application of toxic compounds to plants. Plant extracts have been applied exogenously to strawberry plants before infection with C. acutatum to determine their ability to induce resistance; plants treated with citrus extract shown a similar response to that of the standard induced resistance control.
