BCA against Powdery mildew

BIOCOMES objectives:

• To screen new fungal antagonists for control of Blumeria graminis in wheat
• To evaluate selected antagonists against other powdery mildews or other foliar diseases in wheat

The biological control agent (BCA) that will be developed will be based on newly selected fungal antagonists against powdery mildew in cereals. At the end of the project the efficacy of the BCA will have been shown in multiple field trials. The mode-of-action will be known as well.

For the development of this biological control product a collection of fungal isolates as candidate antagonists (~1000) will be built, all isolated from powdery mildew pustules (a spore mass developing on the leaf). The potential candidate antagonists will be selected by high-throughput screening methods followed by efficacy tests under controlled and field conditions.

The selected antagonist must not only have a high efficacy against powdery mildew but must be suitable for mass production and product formulation as well.
