Downy mildew is caused by Plasmopara viticola, an obligate oomycete plant pathogen, a devasting disease of grapevine. To protect plants from the disease, complex III inhibitors are among the fungicides widely used. They specifically target the mitochondrial cytochrome b (cytb) of the pathogen to block cellular respiration mechanisms.

Knowledge about strain level biocontrol abilities is warranted to translate this knowledge into developing more efficient biocontrol agents and bio-fertilizers.

NSAIDs act through inhibition of cyclooxygenase (COX) conversion of arachidonic acid into prostaglandins. One experiment was carried out whereby marine mussels were exposed for 72 h to 1 and 100 μg/L diclofenac (DCF).

To overcome this stress, fungi have evolved several mechanisms at both intracellular and extracellular levels. In particular, fungi are well known for their ability to secrete a large panel of proteins.
