Botrytis bunch rot (BBR) is a major disease occurring in vineyards worldwide. Its control, still largely based on synthetic fungicide sprayings at pre-determined intervals, often leads to residues in grapes and wines that may negatively affect the en

Aim of study: The productivity of poplar plantations in Mediterranean climates might be reduced due to lower precipitations in a climate change scenario. Therefore, understanding the water consumption in these plantations is essential for their manag

Aims: Long exposure to high temperatures or UV-radiation may induce negative effects on vine physiology and grape composition. Here, the effects of two methods to moderate radiation and temperature in the fruit zone of a Cabernet Sauvignon vineyard w

Aims: Climate-based indices exist for viticulture, particularly for modelling phenological events, but not for vine water status. In this work, climatic variables are linked to the temporal evolution of the water status of the vine Methods and Result

Aim: Recent work has identified strong intra-field relationships of pre-dawn leaf water potential (ΨPD) between paired sites. This study investigates if these relationships exist at the inter-field level when soil types between fields are constant o

Aims: Plant water status monitoring during the vineyard growth cycle constitutes a basic parameter for both harvest quality and vineyard management. Unfortunately, the plant water status measurement requires skills and heavy devices which drastically
