A camera and laser system for automatic vine balance assessment
(Cornell University, 2012-03)An automated system using a cameras and lasers determined crop weight and canopy volume to within 10% in Traminette, Concord, and Riesling, without manual cluster counting and weighing. -
A New, Satellite NDVI-Based Sampling Protocol for Grape Maturation Monitoring
(Cornell University, 2020-05)Cornell Extension Educator Jim Meyers, working with Justine Vanden Heuvel's program and E. J. Gallo scientists, developed an image analysis-based method for using Landsat satellite images to select single, representative ... -
Adopting Under-Vine Cover Crops in Vinifera Vineyards
(Cornell University, 2017-03)Research in the Finger Lakes by Justine Vanden Heuvel, associate professor of enology and viticulture, indicates that planting under-vine cover crops are an effective alternative to bare soils for controlling excessive vigor, ... -
Automating Measurements of Canopy and Fruit to Map Crop Load in Commercial Vineyards
(Cornell University, 2011-11)Crop load - the ratio of exposed leaf area to fruit - is a key measure of vine performance. A collaborative project is using tractor-mounted imaging systems to develop crop load maps capturing variability in vine size and ... -
Crop load adjustment in ‘Seyval blanc’: Impacts on yield components, fruit composition, consumer wine preferences, and economics of production
(Cornell University, 2011-11)Crop load adjustment in 'Seyval blanc': Impacts on yield components, fruit composition, consumer wine preferences, and economics of production -
Downy Mildew is caused by an Oomycete. What’s an Oomycete? Why does it matter?
(Cornell University, 2021-03)Downy Mildew is not a fungus. Dr. Katie Gold explains why plant pathologists distinguish Oomycetes from fungal pathogens, and why it matters for management. -
Enhancing Vine Health with Commercial Arbuscular Mycorrhizal Inoculants
(Cornell University, 2020-11)Mycorrhizal fungi colonize roots and can increase nutrient and water uptake from the soil. Justine Vanden Heuvel's greenhouse and field trials with commercially available products increased root growth and tissue nutrient ... -
Expanding the Use of Under-Vine Cover Crops in New York Vineyards
(Cornell University, 2018-05)Research has shown that under-vine cover crops can help manage vigor and reduce erosion. Grape extension specialists Alice Wise and Hans Walter-Peterson discuss management in Long Island and Finger Lakes vineyards, and ... -
How many grapes in a bottle of wine?
(Cornell University, 2021-05)Chris Gerling revisits his previous article on "Conversion factors: from vineyard to bottle". It turns out it's more complicated. -
Impact of Fruit-Zone Leaf Removal on Rotundone Concentration in Noiret
(Cornell University, 2018-03)Impact of Fruit-Zone Leaf Removal on Rotundone Concentration in Noiret -
Impact of Shoot Thinning and Harvest Date on Yield Components, Fruit Composition, and Wine Quality of Marechal Foch
(Cornell University, 2011-04)In this 2007-2008 study, delayed harvest influenced Marechal Foch wine characteristics more than did shoot thinning. -
Impact of undervine management on vine growth, yield, fruit composition, and wine sensory analyses of Cabernet franc
(Cornell University, 2016-05)Impact of undervine management on vine growth, yield, fruit composition, and wine sensory analyses of Cabernet franc -
Measure and Manage Crop Load to Meet Your Vine Balance Targets
(Cornell University, 2021-03)Senior research associate Terry Bates and colleagues provide a road map for managing vines by measuring crop load - the ratio of yield to vine vegetative growth. 30+ years of research provide solid benchmarks for Concord growers. -
Mechanical Thinning Pays Off for Concord Growers
(Cornell University, 2013-12)Facing heavily overcropped vineyards, Concord growers applied mechanical thinning to 40% of of Eastern juice grape acres, for an economic benefit estimated at $9 to $11 million. Thinning technology is an outgrowth of 15 ... -
Palissage Reduces Cluster Zone Lateral Shoots Compared to Hedging
(Cornell University, 2018-11)Cornell Masters' recipient Justin France, Ph.D. student Ming-Yi Chou and viticulture professor Justine Vanden Heuvel assessed the value of palissage techniques of wrapping and tucking vine shoots as an alternative to hedging. -
Sampling and estimating average pruning weights in Concord grapes
(Cornell University, 2012-11)CLEREL researchers James Taylor and Terry Bates used the data from an intensive survey of pruning weights to determine the optimal sample size and sampling method to estimate the average vine size in vineyard blocks. -
Sensors Provide Information to Guide Variable-Rate Mechanical Fruit Thinning and Prevent Overcropping of Concord Grapes
(Cornell University, 2018-08)The Efficient Vineyard project has successfully used GIS mapping of sensor data to modify harvester bow-rod shaking speed on-the-fly for variable-rate mechanical crop thinning to reduce overcropping. -
Timing and Severity of Leaf Removal and Methoxypyrazines
(Cornell University, 2010-11)Like antibiotics to fight human diseases, antimicrobial peptides can be used to combat disease in grapevines. -
Under-vine Management Impacts Soil Properties and Leachate Composition in a NYS Vineyard
(Cornell University, 2016-08)Vineyard sustainability is greatly influenced by soil quality. This study by the Vanden Heuvel Group shows that under-vine cover crops may conserve soils and also buffer nutrient and agrochemical inputs from leaching into ... -
Using cell phones to obtain accurate prebloom cluster counts
(Cornell University, 2021-08)Viticulturist Justine Vanden Heuvel and engineering professor Kirstin Peterson devise low-cost procedure to count clusters for crop estimation.
