Grape Disease Management Workshops and training

If you wish to attend upcoming grape disease workshops and training, please register using this form (CLICK this line) so that I can send you an invitation to the lecture materials. 

Grape Disease Workshop (3/31/21): I prepared a series of lectures to cover basic concepts and terminologies, which I often not able to explain due to the time limitation. Also, a short version of my "usual" workshop is now recorded. In my workshops, I assume you know some concepts and terms, so, if you are not familiar with some terms such as disease triangle, curative fungicide, QoI fungicide, FRAC group, fungicide resistance, biological control agent, etc, please check out the lectures. 

Each lecture runs less than 20 min, with an exception of the main workshop content, which runs around 26 min. If you do not have time to watch them all, please watch the main workshop content.

On March 31st at noon, we will use Zoom to communicate. The link to the Zoom session is also listed on the Canvas website. I will go over a brief overview of the season with some examples using the template spray plan, and after that, we will spend most of the time with Q and A and discussions. training (4/9/21: The style is nearly the same. We will meet virtually via Zoom on April 9th at noon. The introduction presentation has been updated, but I am still working on the contents. Once I finish all the videos, I will send you an email, but please go ahead with Canvas sign-in. We will use the same Canvas website for both the Grape Disease Management workshop and training. 

A Spanish-translated version of the grape disease workshop (4/1/21) will be on a separate Canvas course. Once again, please register from the form listed above to obtain more information.

If you have registered, I will register you to a system called Canvas, and send you an email; however, it looks like the invitation from Canvas tends to get lost.

At bloom disease management tips

Recent cooler weather seems to have slowed down vine development, but it looks like vines in the south are about to bloom. Bloom is a start of the critical time for cluster infections by downy mildew, powdery mildew, black rot, Botrytis, and ripe rot, because pathogens of these diseases can infect flower parts and develop symptoms later. What I recommend often is the use of protective materials to protect tissues for 4-6 weeks for V. vinifera varieties, and 3-4 weeks for V. labrusca varieties, which should translate into 3-4 sprays for V. vinifera , and 2-3 sprays for V. labrusca .  If you have hybrids, they are somewhere in between, so, 4-5 weeks to be protected.  As usual, please make sure to rotate mode of action (= FRAC) groups. Since we have not seen many rain events, I think powdery mildew will be the primary target for many of us. But please check your local weather to make sure, some downy mildew susceptible cultivars may still show downy mildew, especially, if there are many

Downy mildew gallery

At Winchester, we had light rain events during the night of 6/12/09, but it was short events and the relative humidity was low (80% or so), thus it probably did not promote any infections. However, we are experiencing continuing favorable nights for downy mildew sporulation (average T>55F, high RH (80-100%)) for 10 days now. Yesterday, we conducted a formal disease assessment, and observed first incidence of powdery mildew for this season. We had plenty of infection events in last two months, so it was not surprising. At this point, it is a trace level of infection on untreated vines. Downy mildew was the major disease so far. We had up to 40% incidence on untreated vines. Next runner-up was black rot. It varies vine to vine, but some of vine had 10-15% incidence. Phomopsis was omnipresent as I expected from early May rain falls, but severity was low overall. We will examine diseases again in the near future, and I will update as the season goes. Here is downy mildew ga
