Implementation of precision viticulture techniques requires the use of emerging sensing technologies to assess the vineyard spatial variability. This work shows the capability of multispectral imagery acquired from a remotely piloted aerial system (RPAS), and the derived spectral indices to assess the vegetative, productive, and berry composition spatial variability within a vineyard (Vitis vin...

OBJECTIVES Copper-based compounds have been used as agricultural fungicides for many years. Their use in Australia is escalating with increase in the scale of planting and associated pest problems. The objective of this study was to identify viticulture activities associated with high exposure to foliage sprays. It would be determined if occupational exposure of vineyard workers to copper-based...

8 The increasing availability of Very High Spatial Resolution images enables accurate 9 digital maps production as an aid for management in the agricultural domain. In 10 this study we develop a comprehensive and automatic tool for vineyard detection, 11 delineation and characterization using aerial images and without any parcel plan 12 availability. In France, vineyard training methods in rows...

Demands for geospatial information and geodata accessibility to support vineyard management using new technology for precision farming are increasing worldwide. In this paper a WebGIS application is presented, it has been developed to support the on-going researches of Consorzio Tuscania Project on precision viticulture in Tuscany, aiming at the assessment of the impact of different vineyard ca...

Background. Grapevine leafroll disease is one of the most widespread viral diseases in vineyards, affecting nearly all grape and wine regions in the world. Infection causes yield losses, ripening delays, and alters fruit chemistry, including lowering soluble solids and increasing titratable acidity. The viruses associated with leafroll disease are transmitted through propagation of infected mat...

Vineyard bird control is an important issue both monetarily and practically. Each season vineyard managers face the real threat of significant crop loss to starlings and finches, as well as an assortment of other birds. The increased popularity of wine as a mainstream consumable has led to a higher crop value in this industry. Because of this, the grape growers can no longer ignore bird damage....

Sci., 20: 849-855 Mycorrhizal fungi’s Glomus spp. and Trichoderma spp. are natural components of the healthy vineyard soils. They have the ability to improve nutrition and root resistance to attack by pathogens, and contribute positivel...

Control of ants using baits of low toxicity cannot be effective without knowledge of bait distribution patterns and bait station densities, which are determined by ants' foraging activities. Furthermore, the success of toxic baits also depends upon attractiveness of bait carriers. Here, we assessed ground and vine foraging activity and food preferences for the three ant species ( Linepithema hu...
