What is this plaque on bow feathers

On the bow (green feathers) some strange coating, like ashes, and rough to the touch. What could it be?


Peronosporosis is. Unfortunately, if you treat with fungicides (Ridomil Gold, etc.), you can pick onions only after 20 days, well, feathers should never be eaten. I dusted mine with ash through a sieve - I don’t see any new defeats yet. But this bow in any case will be stored poorly (((
