We are seeing a lot of powdery and downy mildew on grapes this year. These diseases often get established in the late season after harvest. It is important to maintain healthy foliage all the way until frost to maximize winter hardiness. So managing these diseases is important in years like this. Growers should consider a late season application of fungicides to keep these diseases under control to protect the foliage and assure adequate cold acclimation. Downy can be controlled after harvest (when PHIs are no longer a concern) with phosphorous acid products, mancozeb, captan or one of the newer products such as Presidio, Ranman or Zampro. However, none of those fungicides will control powdery mildew (which is much worse in our plantings). So a tank mix including one of the above with a DMI fungicide such as Rally or Tebuzol would be a good approach. There are several other options[Read More…]

Grape harvest is underway for early and mid-season varieties. Downy and powdery mildew are showing up in vineyards. Table grapes have been especially nice this year. Primocane bramble harvest is also underway. Surprising low number of spotted wing Drosophila have been found in grapes or brambles. Frequent rains are very unwelcome as they generally have a negative effect on fruit quality in both grapes and brambles. Gala and Honey Crisp apples are being harvested. Weeds and row middle covers are growing excessively with all the recent rains.


rotting grapes

2018 is looking a bit like 2016 with all this late summer rain. We’ve had statewide rainfall each of the past 5 weeks. Most unwelcome! Sour rot and Ripe rot are becoming common in our research trials and vineyards around the state. Early ripening thin-skinned varieties are especially prone to skin splitting and cracking due to rain. Once opened, the berries are quickly invaded by yeasts, bacterial and fruit flies. Sour rot with its characteristic vinegar odor is the end result. There is nothing a grower can do to stop the rain, but there are some approaches to reducing sour rot. Canopy management is an important aspect for many varieties. Sprays of insecticide to control fruit flies plus an antimicrobial such as Oxidate or Fracture have shown some success. Best results occurred when sprays were started at 15 Brix. Sour rot is mainly a concern on the thin-skinned, tight cluster[Read More…]

With harvest around the corner for many fruit crops, I thought this would be a good time to remind readers about our email lists. Various forms of social media is used by just about everyone in today’s society.  While Facebook and Twitter are much more commonly used than email, there is still a place for email lists. Mail lists continue to be a successful communication tool for groups of people. The way a mail list works is that people subscribe and then have the authority to post messages to the list. All other subscribers on the list receive the messages. One message can be sent to hundreds of readers at once. Replies to messages on a mail list can either go only to the sender of the message or to the entire list. Purdue HLA Extension maintains two mail lists for users. The “Fruitveg” list is for all fruit and vegetable growers, farm[Read More…]


Grape harvest is just about to get started in the southern part of the state. Growers will start harvesting early varieties next week. Most varieties are slightly ahead of normal this year. In Lafayette, early varieties are at full veraison and should be ready to harvest in the next couple of weeks. We generally harvest early varieties such as Brianna, Edelweiss and Prairie Star about the third week of August and many other early varieties starting the first week of September. Depending the weather for the next couple of weeks, we might be a bit early this year. Fruit quality overall is very good. The cooler conditions lately have favored fruit quality. With wine grapes, all fruit of a given cultivar is typically harvested from the vineyard or block at a single time to coordinate winery activity and to reduce costs. It is important to plan carefully so that the[Read More…]

grapes turning color

Early grapes are just beginning to soften and color (veraison). Summer raspberry harvest if winding down and fall bearing types are flowering. Blueberry harvest continues. Japanese beetle numbers continue to be relatively high in the Lafayette area. Peach harvest (for those fortunate to have a crop) has begun. Early apple cultivars are approaching harvest.
