Biological control of plant diseases – What has been achieved and what is the direction?

The global sustainability agenda is increasing the demand for reduction in inputs into agricultural production while maintaining profitable yield of quality products. Plant diseases are a major constraint both and product quality, but often tools their control ineffective or lacking. Biological using antagonistic microorganisms has long been subject research resulting wide range products that now available marketed specific territories around world. These preparations niche with narrow uses. effort intense to develop new biological agents (BCAs) obtain knowledge mechanisms underlying disease control. prospects promising. As minimum, BCAs supplement other sustainable management practices such as resistance, present opportunities controlling which approaches unavailable. We can realistically expect use crop ways will benefit environment. This review paper arose from webinar held by British Society Pathology part International Year Heath (IYPH2020), at many 300 participants posed discussed interesting questions. based on input panel members all included co-authors this review.
