More Blueberry Damage Photos

Last Friday I visited a grower in the Collins/Mt. Olive area who had some damage to his blueberries.  Luckily for him he did have some frost protection going (overhead irrigation), but that still did not spare all plants.  One could see obvious gaps where the water did not adequately cover the plants, and those plants lost quite a bit more than those that were covered by ice.  By my estimates he had up to 50% loss in one field and up to 30% in another.  The later field had the frost protection, but it was also a couple of days later in development — likely sparing many of the blooms as well.  Take a look below at a couple shots of the damage I saw:

The grower had applied ProGibb and Pristine.  He was going to apply ProGibb again along with Captan to control Botrytis.  You can find more comments on using fungicides against Botrytis in my newsletter (http://msucares.com/newsletters/vaccinium/2013/msjv_2_2.pdf), as well as info on the effects of the freeze event on Mississippi blueberries.
