    When a retired farmer and organic farming consultant is motivated to put his boots back on and get back into the fields, you know something special is happening. That’s exactly how Daniel Rotberg felt when he studied the first GroAloe trial conducted on grapes with a major leafhopper infestation. The trial shows that, “The overall health of the Vineyard has completely transformed from weak and in some places, diseased plants, to a robust and healthy condition with many more grape shoots now forming... ” The results that GroAloe is showing on crops ranging from grapes grown in Canada, rice in Indonesia to Cannabis and Hemp in California and Oregon are remarkable...

    From Industrial Pesticides to Integrated Pest Management: A New Trend in Vineyard Practices

    By Thomas Grandperrin

    Updated Dec 14, 2020 

    This article was initially published on The Wine Industry Advisor as part of a series on biological control and Integrated Pest Management written by UAV-IQ Precision Agriculture. Grape growers are facing increased threats from invasive insect pests. The issue with those non-native species is that there are often no naturally occurring enemies capable of controlling them and new Integrated Pest Management (IPM) protocols might take years to be developed, forcing growers to rely on broad-spectrum insecticides until more ecologically friendly alternatives are available. A notable example of an invasive pest affecting California vineyards is the vine mealybug, which is a major pest of grape vines not only because of the damage they can cause to the fruit but also for the viruses they transmit, such as the grape leafroll-associated virus... Kent has led several research projects on vine mealybugs and the development of ecologically-based insect pest management systems in vineyards and other perennial crops, such as almonds, pistachios, grapes, and stone fruit...

  • Disease Detection in Tree Leaves and Fruits using Image Processing Techniques

    Authors: Nivetha. I, Dr. M. Padmaa

    Published in: Journal of Radio and Television Broadcast: 3 pp. 24-28.
    Communities: MAT JOURNALS

    India is the agriculture based country. Now a day, agricultural product yield is decrease for the reason of disease affect the plants like fungus, virus diseases. In this paper, we detect the tree leaves and fruits disease using image processing techniques. In this paper apple, grapes and pomegranate disease are detected. The apple diseases are apple scab, apple rot, Marssonina leaf blotch, black rot canker, apple mosaic. The grape diseases are black rot, powdery mildew, downy mildew, anthracnose, bacterial leaf spot, and rust. The pomegranate diseases are bacterial blight, aspergillus fruit rot, anthracnose, cercospora fruit spot, cescospora leaf spot.

    Use of multispectral and thermal imagery in precision viticulture

    Authors: G Tanda and V. Chiarabini

    Published under licence by IOP Publishing Ltd
    Journal of Physics: Conference Series, Volume 1224, conference 1

    The increasing demand for higher quality and yield of wine production has led to a growing interest in precision viticulture, i.e., practices of monitoring and managing spatial variations in variables related to productivity within a vineyard. This paper presents a few applications of optical measurements, in combination with monitoring systems making use of geolocation and remote/proximal sensing, to calculate vegetation indices related to plant vigour and water stress in vineyards. Measurements were performed on vineyards in Burgenland, Austria, by both aerial and proximal (terrestrial) sensing techniques. A remote-sensing, four-band multispectral sensor, placed on an Unmanned Aerial Vehicle (UAV), has been used to detect the spectral signature of the vineyard and to calculate the NDVI index, useful to selectively address the harvest on the basis of quality and quantity of grapes. Proximal, thermal infrared imaging complemented the investigation providing information about the water status of the vegetation through the CWSI index. Examples of vigour maps are provided, showing, inside a given parcel, the presence of canopies at different level of vegetation characteristics. Results provide a range of information useful to make the optimal choice in management strategies of vineyards.

    VineRobot, an Unmanned ground vehicle equipped with non-invasive sensor technology to monitor grape growth

    The VineRobot is equipped with non-invasive advanced sensors and artificial intelligence systems, to provide reliable, fast and objective information on the state of the vineyards to grape growers. Thanks to these technologies, VineRobot will be able to work — that is, retrieving agronomical and physiological data from the grapevines — autonomously and safely over long periods of time under the uncertain environmental conditions typically found in vineyards.

    The first version of the VineRobot incorporates a fluorescence-based sensor to assess nitrogen content in leaves. The measurement is performed on-the-go and provides information about the heterogeneity and state of the vineyard.
    The other sensor included in the VineRobot measures the anthocyanin content in grapes. This sensor is a fusion between a fluorescence sensor and a fine vision system: It gathers information about the composition of grape berries.
