Does scab reduce fruit set?
The last few years in Seattle have not been particularly cooler (like many places a couple years ago) nor have they been warmer (like many places last year)....what we have had, though, in the PNW is a whale of a lot wetter weather and I am convinced this can affect our fruit set.
Of course this idea of rain affecting fruit set is a no-brainer when it comes to the idea of rain driving away the bees in the Spring when they are needed for pollination....but I also believe that an increased incidence of anthracnose (which can come from more Fall rains) is also reducing our fruit set.
My question is this: since we know pear and apple scab are increased by more rain in the Spring, could it be that scab not only blights the look of the fruit but that it too is reducing the fruit production as well?
Thanks in advance.
