Introduction Grapevine leafroll-associated viruses (GLRaVs) and grapevine red blotch virus (GRBV) cause substantial economic losses concern to North America’s grape wine industries. Fast accurate identification of these two groups is key informing disease management strategies limiting their spread by insect vectors in the vineyard. Hyperspectral imaging offers new opportunities for scouting. Methods Here we used machine learning methods, i.e., Random Forest (RF) 3D-Convolutional Neural...
The latest Hunger Hotspots Report by the Food and Agriculture Organisation (FAO) World Programme (WFP) of United Nations highlighted 16 hotspots in which food insecurity is increasing due to conflict, economic instability, extreme weather events [...]
The current rise in temperatures is hastening grape ripening, resulting unbalanced wines with high alcohol content but poor colour, aroma and phenolic composition. Late-season canopy manipulation practices aimed at reducing the size of photosynthetic apparatus after veraison have been shown to delay ripening cooler climates. However, these methods not directly compared regions irradiance temperature, where berry composition negatively affected by late fruit exposure. In this two-year...
The main challenge encountered by Mediterranean winegrowers is water management. Indeed, with climate change, drought events are becoming more intense each year, dragging the yield down. Moreover, quality of vineyards affected and level alcohol increases. Remote sensing data a potential solution to measure status in vineyards. However, important questions still open such as which spectral, spatial, temporal scales adapted achieve latter. This study aims at using hyperspectral measurements...
Wine growing needs to adapt confront climate change. In fact, the lack of water becomes more and important in many regions. Whereas vineyards have been located dry areas for decades, so they need special resilient varieties and/or a sufficient supply at key development stages case severe drought. With change decrease availability, some vineyard regions face difficulties because unsuitable variety, wrong vine management or due limited access. Decision support tools are therefore required...
Abstract Remote sensing is now a valued solution for more accurately budgeting water supply by identifying spectral and spatial information. A study was put in place Vitis vinifera L. cv. Cabernet-Sauvignon vineyard the San Joaquin Valley, CA, USA, where variable rate automated irrigation system installed to irrigate vines with twelve different regimes four randomized replicates, totaling 48 experimental zones. The purpose of this design create variability grapevine status, order produce...
The wine industry must face many challenges because of climate change. One them is the increase in temperatures and droughts events. These changes sometimes lead to yield losses can also impact quality produced (e.g., increased alcohol content). management available water a sensitive issue as requirements for vineyard irrigation are quickly increasing south France. In this context, there need decision tool that help evaluate vine status through entire growth season at large scale. To address...
A decade since its discovery, Grapevine Red Blotch Virus (GRBV) has revealed significant impact on grapevine physiology, grape composition, and wine production. To mitigate spread in vineyards, the imperative to identify remove diseased vines necessitates autonomous scouting for enhanced roguing as a disease management response. Remote sensing, especially hyperspectral imagery, shows promise identifying virus-infected vines. However, detailed data it provides, while rich, presents processing...
