  • Best way to control powdery mildew on grape plant

    By Darren Chan

    Published 11 months ago

    If you grow grapes,you may reaching to see a white powdery substance on the grape leaves. It’s the grape powdery mildew. Especally in main grapevine growing area such as Americas,Europe and Australia. The disease seems as a whitish-gray powdery coating on the leaves or fruit caused by plant mycelium and conidia on the surface of the plant... If leaf cover is thick, expose developing grapes and improve air circulation by removing leaves at the bases of the stems...

    Why magnesium is important for grape?

    By Darren Chan

    Published 1 years, 3 months ago

    Magnesium’s effect is essential for grape,it can be called “a large number of elements” for grapes,and the demand is simliar to phosphorus. Even the magnesium content of grape leaves is higher than that of phosphorus. It is directly involved in physiological and biochemical processes such as photosynthesis and enzyme activation of grapes,and is one of the mineral elements necessary for normal growth and development of grapes and improvement of fruit quality... The photosynthesis of grapes,the conversion of phosphorus,the formation of pectin substances and vitamin A,and the elimination of the harmful effects of excess calcium are all inseparable from the participation of magnesium... Improve the yield and quality of grapesMagnesium can promote photosynthesis,strengthen carbon dioxide fixation and dry matter accumulation,which is an important factor affecting the formation of grape quality...

  • 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.

    Mini review: Fruit Residues as Plant Biostimulants for Bio-based Product Recovery

    Authors: Andrea Ertani, Ornella Francioso, Serenella Nardi

    Journal Title: AIMS Agriculture and Food

    ISSN: 2471-2086 (Online)

    Publisher: AIMS Press

    The request of natural products has augmented in the last years due to the increase in intolerance and allergy reactions showed by humans versus pesticides and certain chemical compounds used in agriculture. In response to this demand, innovative methods and new natural matrices have been exploited to obtain products able to increase plant nutrients use efficiency. In this context, agro-industrial residues contain bioactive molecules, including antioxidants and phenols, which may be used by farmers to improve crop productivity. Phenols are ubiquitous in plants and are essential components of the human diet by virtue of their antioxidant properties. They may also act as positive growth regulators by modifying the root architecture and, consequently, the uptake of macronutrients, potassium especially. In order to understand their effects on the plant metabolic pathways, agro-industrial residues were supplied to maize plants and the activity of specific enzymes was evaluated. In this review, developments and improved understanding on fruit residues on primary and secondary plants metabolism are discussed.

    Soil Salinity and Moisture measurement system for Grapes Field by Wireless Sensor Network

    Soil moisture and salinity measurement are the essential factors for crop irrigation as well as to increase the yield. Grapes eminence depends on the water volume contents in soil and soil nutrients. Based on these conditions, we determined water demand for best quality of grapes by wireless sensor network (WSN). Using lot of chemical fertilizers increases soil salinity but reduces soil fertility, soil salinity defines electrical conductivity or salty soil. Precise agriculture systems are integrated with multiple sensors to monitor and control the incident. Integrated WSN is designed and developed to measure soil moisture and salinity. ATmega328 microcontroller, XBee and Soil sensors are integrated across the system. This system is more competent, it can be helpful to automatic irrigation system and soil salinity monitoring.
