This winter was significantly colder than normal in the northern half of Indiana. Many areas north of “I-70” experienced temperatures between -15 and -20˚F in early January. That is cold enough to cause considerable cold injury to grapes, peaches, and blackberries. See the map below for minimum winter temperatures. We have evaluated crops at the…Read more about Determining Winter Injury in Grape Vines[Read More]
Summer rots continue to rear their ugly heads (Fig. 1). This year, we are even seeing them on late season apples like Evercrisp (Fig 2) and GoldRush. On the plus side, we are seeing some level of control with all fungicides in our trials (data will be presented at the Indiana Hort Congress); unfortunately,…Read more about Rot Redux[Read More]

Growers should consider a late season application of fungicides to…Read more about Late Season Leaf Diseases of Grapes[Read More]

Grapes are among the most sensitive fruit crop to crown gall. The disease is caused by the bacterium Agrobacterium tumefaciens. This is the same bacterium that is used to genetically…Read more about Crown Gall of Grape Vines[Read More]
There are a number of common grape pathogens that can cause fruit rots each year in the region. Black rot and Phomopsis cane and leaf spot are by far the most common fruit pathogens. We also see Botrytis gray mold on some cultivars in cooler regions and years. Another common rot is Sour rot, but…Read more about Ripe Rot on Grapes[Read More]
Fruit rots continue to pose a problem for those of us in the wetter parts of the state. Frequent rains and warm temperatures really set the stage for bitter rot, black rot, white rot, and even brown rot. Any rain event that produced more than 2” of rain would remove the majority of fungicide, meaning…Read more about Fruit Rots[Read More]
