Biological control of plant diseases
2000
The present chapter reviews the question of developing a microbial control method of plant diseases. All problems which may occur, from the initial screening of an efficient biocontrol agent to the final step of integration of the biological control method into the crop management system are briefly examined.
Testing Multi-Sensors Time Series of Lai Estimates to Monitor Rice Phenology: Preliminary Results
2018
Timely and accurate information on crop growth and seasonal dynamics are increasingly needed to develop monitoring systems aimed to detect seasonal anomalies, support site specific management and estimate crop yield at the end of the season. In particular, frequent decametric information nowadays being provided exploiting the new generation of Earth Observation (EO) platforms are fundamental for farm level monitoring. This study presents an analysis aimed at fully exploiting dense time series of EO data derived from the combined use of ESA Sentinel-2A and NASA Landsat-7/8 imageries for crop phenological monitoring. Decametric Leaf Area Index (LAI) maps were generated for the year 2016 by in…
Consecuencias del manejo integrado de malas hierbas sobre la organización del trabajo y la rentabilidad económica de la explotación agrícola
2008
International audience; Este trabajo tiene por objeto analizar la viabilidad de los sistemas de protección integrada de malas hierbas desde el punto de vista de la organización del trabajo y de la rentabilidad económica. Para ello se comparan cuatro sistemas de protección integrada que reducen o suprimen el aporte de herbicidas, con un sistema convencional. La metodología combina el uso de un programa de simulación con los resultados reales obtenidos en ensayos localizados en una finca experimental del INRA en Dijon (Francia) durante el periodo de 2000 a 2006. Así, se estiman los problemas de organización de trabajo y el margen neto de las explotaciones utilizando los datos reales del exper…
A Review of the Most Common and Economically Important Diseases That Undermine the Cultivation of Tomato Crop in the Mediterranean Basin
2021
Tomato (Solanum lycopersicum L.), family Solanaceae, has become in the past fifty years one of the most important and extensively grown horticultural crops in the Mediterranean region and throughout the world. In 2019, more than 180 million tonnes of tomato have been produced worldwide, out of which around 42 million tonnes in Mediterranean countries. Due to its genetic properties, tomato is afflicted by numerous plant diseases induced by fungal, bacterial, phytoplasma, virus, and viroid pathogens. Not only is its genetic inheritance of great importance to the management of the numerous tomato pathogens, but equally as important are also the present climate changes, the recently revised phy…
AN INNOVATIVE SYSTEM FOR VINEYARD MANAGEMENT IN SICILY
2010
The aim of this study was to monitor the micro-climate of the grapevine in order to detect the adversities of the spring period (especially April and May), while reducing the operating costs of the vineyard, and increasing the overall quality of grapes. For this purpose a Wireless Sensor Network (WSN) was used. Furthermore, a comparison was performed between data measured by the wireless sensors and data provided by the fixed meteorological station of the Regione Siciliana (SIAS).
Conservation agriculture : how farmers manage weeds
2020
International audience; Conservation agriculture is characterized by the continuousand simultaneous application of three principles:minimum soil disturbance (no-tillage), residue cover onthe soil surface (dead mulch or cover crop) and diversecrop successions and cover crop mixes. Adopted inFrance by farmers since the 1990s, this farming systemstill faces some challenges to its adoption, particularlyfor weed management. To highlight this problem,425 French farmers practicing conservation agriculturewere surveyed by an online survey. Cultural practicesused to manage weeds during the first years of conservationagriculture were requested. The use of each culturalpractices was first studied inde…
Analyse multi-échelles des compromis entre services écosystémiques fournis par la flore adventice
2021
Weeds contribute to the provision of various ecosystem services, negative when linked to their harmfulness (disservices) and positive due to the provision of trophic resources (floral resources, seeds) to pollinators and pest natural enemies (services). In this PhD thesis, we analysed how crop management strategies (coherent crop sequences and associated farming practices) implemented by farmers within a small agricultural landscape modulate the weed contribution to (dis)services provision. We also assessed the relative contribution of field cores and field edges (narrow area between the 1st row of the crop and the boundary) to these services. At the annual scale, we show that crop type hig…
Identification of sustainable cropping systems with high multi-sector performances
2014
International audience; Multicriteria assessment is needed to identify promising cropping systems with good performances on different components of sustainability. Some trade-offs between criteria may occur. A better knowledge about the relationship between criteria can help (i) to ide ntify cropping systems with high multi-sector performances (e.g. Castoldi et al., 2010; Firbank et al., 2013), and (ii) to guide policy makers’choices. In this paper, we present the early results from our multi-sector evaluation performed on data collected on cropping systems experiments.
Soil water repellency assessment in olive groves in Southern and Eastern Spain
2016
Soil water repellency (SWR) has been reported under different soils, land uses and regions of the world, particularly in forest land and after wildfires, yet the understanding of this variable in agricultural lands is still rather limited. This study presents the characterization from field-based measurements of SWR in four contrasted olive groves (Olea europaea L.) in Spain in terms of different environmental conditions and management: abandoned and commercial farms under permanent cover crop, conventional tillage and herbicide use. The main objectives were [1] to evaluate the potential occurrence, intensity and persistence of soil water repellency in different types of olive groves and [2…
