Grapes


We’ve had some weird weather this year. April was cool and crop growth was delayed. But once May arrived, warm conditions lead to rapid development of fruit crops. We are now about “normal” in development. That means that grapes in the southern half of the state are nearing the pre-bloom stage, which is a key…Read more about Important Pre-bloom Sprays for Grapes[Read More]

What a difference a couple of weeks of warm weather makes. Crop development is progressing rapidly with warmer weather. Apples in the south are around 10 mm, and in full bloom here in Lafayette. Peaches in southern areas of the state are still in the shuck, but barely. Folks in southern areas are getting ready…Read more about Crop Conditions[Read More]


Fruit crops are finally starting to grow in the Lafayette area after a few days of warmer weather. Apples are at 1/2 inch green to tight cluster. Peaches have 1/2 inch vegetative shoots. There are no live flower buds in our planting. Cherries are at swollen bud. Early grapes varieties are at swell. Raspberries have…Read more about Crop Conditions[Read More]


“Spring” might be too strong a word to describe conditions this year. As we see from Figure 1, we’re now officially the latest spring so far this decade, and about the same as the long-term average. Having said that, a good part of our Growing Degree Day accumulation has come from one warm day on…Read more about Spring 2018[Read More]


There are some potential pest and disease problems that require early season sprays. Phomopsis is a major problem on many grape varieties in the Midwest. Mancozeb should be applied starting at 1-3 inch shoots and repeated each 7-10 days, especially prior to a predicted rain event. Evaluations of delayed-dormant fungicide applications for management of this…Read more about Early Season Sprays for Grapes[Read More]


For organisms that don’t regulate their temperature (such as plants and insects), the rate of development is largely controlled by the temperature of their environment. As we know, fruit trees and vines need a certain amount of “winter chilling” that they use to measure when winter is over. After the chilling period, plant development depends…Read more about Plants and Temperature[Read More]


Early spring is a good time to make the first herbicide application of the year. There are several options for fruit crops including both pre- and post-emergent herbicides. See the weed control chapter in the 2018 Midwest Fruit Pest Management Guide for a complete list of products. In most situations, there will be some emerged…Read more about Spring Weed Management in Fruit Crops[Read More]
