Use of natural plant compounds against fungal diseases of grains


The problem of seed-borne diseases is one of the most important threats to crop production in many crops, through reduced plant yields, lowered germinability, reduced vigour, growth, loss of or reduced function and damage to tissue and organs. Seed borne fungi are carried with, on or in seeds, and in suitable environmental conditions may be transmitted to cause disease in developing seedlings or plants. This fungal contamination occurs before and during harvesting, as well as during storage. Pathogenic fungi grown on seeds can cause substantial quantitative and qualitative losses to grains, rendering them unfi t for human and animal consumption. In addition, many species are capable of producing mycotoxins and secondary metabolites that are highly toxic to animals and humans. Therefore, the control of pathogenic organisms present on/in seeds is essential, particularly for organic production, where less effi cient options/ agents are available for protecting and crop plants from diseases.
