After the meeting on Wednesday, there was a request for more information on sour rot management through use of insecticides for control of SWD. I contacted Megan Hall, who conducted this research at Cornell. She indicated that the 2016 research continued to support the use of MustangMaxx. She states, “If a grower knows that they […]

In addition to Botrytis, there is a goodly amount of powdery mildew starting to show up (see photo from today). Based on the current levels of downy and powdery mildew observed, we have a potentially difficult season ahead – once more. Remember, you are fighting an epidemic, which is a movie yet to be made; […]

Rainfall has been plentiful this spring and early summer in many areas across the Southeast, which is a considerable change from last year in many of the same areas. A wet summer can put additional stress on weed management programs and result in escaped weeds that thrive. If you have young, newly planted vineyards make […]

We recently had a Norton (aka Cynthiana) vine submitted to our clinic by Clark McAllister (county agent in Lumpkin County), and the vine(s) were showing odd symptoms for Norton. Leaves were somewhat chlorotic, but the major concerning symptom was a ring spot on the leaves, along with spots on the shoots which are similar to those of […]

I have had a few questions relative downy mildew management, especially with the floods of the last week. Relative Abound fungicide, I would not trust any of the strobilurins alone for downy mildew management. If using Abound, I would use the high rate, and I would add some Captan to the mix. When using any […]

There is a big hairy beast starting to show up out there, and unfortunately, it is not Big Foot. We are starting to observe Botrytis in some vineyards, so it is time to scout for this pathogen. Cain Hickey took this photo, and he states the following: “This is a reminder to pay attention to […]

As I am writing this, the water is gushing down. Needless to say, we have experienced significant rainfall as of late. When it hasn’t been raining, it has been cloudy and humid. This is “great” fungal disease weather – especially for downy mildew and black rot. With the rain we have been experiencing, contact chemicals […]

Japanese beetle season is upon us. These beetles feed on over 300 species of plants including tree fruits, small fruits, vegetables, ornamentals, and of course, grapes. Japanese beetles can be a severe pest of grapes during the summer, feeding mainly on foliage and (thankfully) rarely on the berries.

At this stage, most are hopefully finished with shoot thinning and tucking and now are doing some remedial canopy work – such as fruit-zone leafing and canopy hedging. Remember – intensive leaf removal is best done early (i.e. peppercorn to pea size berries at latest) in order to acclimate fruit to the radiation and temperatures […]
