Bud break and rain...


Bud break for our younger (2-3 years old) Chardonnay happened around 4/20/2018, and for older Chardonnay, it was the last weekend, (4/27/2018). Looks like we are about 1-2 weeks behind of a "typical" spring.

But as with a typical spring, rain comes when grapes break buds! Looks like we will see some precipitations this weekend. Please make sure to have a good protection against Phomopsis as we discussed in the previous post. 

Let's hope that our season will be as good as 2017.

Spray before the upcoming storm?

I received several emails and phone calls concerning spray before the upcoming hurricane Florence. Hopefully, we will have a window of opportunity to apply materials. Looks like we have a break from rain starting tomorrow for maybe 1.5 to 2 days. Here is the list of materials with low PHI (same as the one I posted last month). Just FYI: here are previous posts about... Late season downy management Botrytis gray mold management Once you have about 1.5-2 hours for the materials to dry after application, that will be sufficient for them to stick to the leaf and cluster surface. Good luck!!

Disease risks 7/12-14

An extensive wetness event was recorded on 7/12-13 (~30 hours) with a temperature range of upper 60F to lower 70F.  In addition, there was about 9 hours of wetness recorded in 7/14 with an average temperature of 70F.  Both were infection risk events for downy mildew and Botrytis (especially the long one in 7/12-13).  (These were infection events for black rot and Phomopsis, but berries should be resistant to black rot infection and Phomopsis is typically not active late in the season.) (Note: for some reason I was not able to upload this note on time.  Sorry!)

Disease risk event from this Monday-Tuesday

I had a meeting and did not able to post it in timely manner, but there was a wet event on Monday-Tuesday this week.  It was 14+ hours of wetness and average was around 60F.  It was a risk event for downy mildew, and very low risk for Botrytis. Other than a slight chance of rain tomorrow, it looks like we will have a nice cool week!  For the late season spray recommendations, please refer to previous posts. http://grapepathology.blogspot.com/2014/08/note-on-sour-rot.html http://grapepathology.blogspot.com/2014/08/last-stretch-spray-consideration.html
