Botrytis update for Nova Scotia - May 26th, 2017

Friday, May 26, 2017

So we are getting lots of rain today.  If you have a significant amount of open flower and you have a history of Botrytis you would have needed to apply a control before this wet period.  If you are still early, with <10% open flower, Botrytis infection risk should be low.

However, as we move into early next week and as flowers start to open, I expect Botrytis risk will be high if we get another wet period.  We have had lots of wet conditions that would have enable the disease to start cycling on other plants.

The important thing to remember, any product you are using should be applied before the wet period starts in order to prevent infection.  Most of the newer products ideally need a couple of hours to ensure they are into the leaf, before a rain fall.

I was looking at some fields this week and saw the first signs of Monilinia infection.

It was not very hard to find infection in this field.  It was an early field and to my knowledge had not been sprayed to manage Monilina. When the sun comes out on Saturday afternoon or on Sunday, you should start seeing more and more symptoms if your crop wasn't adequately protected.
