Mapping and determinism of soil microbial community distribution across an agricultural landscape.

2015

Article en open access; International audience; Despite the relevance of landscape, regarding the spatial patterning of microbial communities and the relative influence of environmental parameters versus human activities, few investigations have been conducted at this scale. Here, we used a systematic grid to characterize the distribution of soil microbial communities at 278 sites across a monitored agricultural landscape of 13km(2). Molecular microbial biomass was estimated by soil DNA recovery and bacterial diversity by 16S rRNA gene pyrosequencing. Geostatistics provided the first maps of microbial community at this scale and revealed a heterogeneous but spatially structured distribution…

How rare arable weeds are descriptors of low farming intensification?

2015

International audience; Recent emphasis has been placed on the rapid destruction of the planet’s biodiversity in allhabitats. Rare arable weeds, also known as segetal plants, are threatened species, mostly indecline due to intensive farming systems. However, the presence of these species is intrinsicallylinked to agroecosystems. Their survival is apparently related to low-input agronomic practices.Could these weeds therefore be good descriptors of low agricultural intensification and be goodindicators of high environmental field value? We propose to examine the relationships between thefarming systems and weed flora sampling in the same fields.

Histoire de l’utilisation des herbicides sur deux grandes cultures en France

2010

Wheat and vineyard are two emblematic crops of French cropping systems. Weedmanagement in these crops have been at the root of the development of chemical weedcontrol in France for many other crops. The data presented in this study were collected inthe “index phytosanitaires ACTA” from 1961 to 2010. This paper presents the evolution ofnumber of herbicide molecules and mixtures, and number of commercial products availablefor these two crops. Finally, the modes of action (HRAC classification) is proposed for eachcrops.

Réduction du nombre de molécules herbicides : conséquences par culture. Problématique particulière de la gestion de la flore adventice

2013

All national and European legislations contribute to the present reduction in the available herbicide number. This evolution leads to the decrease in the number of chemical families and to a dramatic reduction of the number of modes of action in some crops or crop rotations. This could lead to the selection of new herbicide resistances. So we may find contrasted situations: crops weeded with only a few herbicides or some herbicides used in almost all crops. The drastic reduction in the available active ingredients without taking into account the benefit-risk ratio or without planning realistic alternative solutions may create tougher agronomic constraints. A data base built up from all the …

Is there a microbial sub alpha-diversity at soil microscale ?

2012

The distribution of the soil microbial diversity depends on a broad range of environmental filters nested in spatial scales from continent to millimeter. Although microbial biogeography studies have recently shown the influence of environmental factors (texture/pH/plant cover and land-use) on soil microbial abundance and diversity, little is still known about spatial heterogeneity at a micro-scale within soil. Our study aims at describing and understanding the distribution of abundance and diversity of soil microbial communities between different soil microenvironments. Four soils were selected on the basis of differences in physico-chemical properties and historical land-management practic…

Biocontrol of weeds toxic to human and animal health

2022

imson weed (Datura stramonium L.) is an invasive weed plant that produces alkaloids that are particularly toxic to humans (crop contamination) and animals (fodder). The objective of my research project is to find a biocontrol solution based on the use of fungi (even oomycetes) and/or plant extracts to control this plant in agricultural plots. At first, I focus on the research of mycoherbicides. The presence of pathogens or phytotoxic metabolites for jimson weed in a panel of non-infested soils to highly infested soils is tested by applying aqueous extracts or filtrates (0.2µm) of these soil extracts to datura seeds placed on germination paper under controlled temperature and humidity condit…

Historique de l'utilisation des herbicides en France: premières analyses

2010

A data base on the herbicides used in France since 1961 has been built up from the phytosanitary index annually edited by the Association de Coordination Technique Agricole (ACTA). This data base gives the number of active ingredients, associations and commercial products registered every year and for each crop. We also gathered the modes of action, the way of absorption sites and the species susceptibility. Since 1961, 215 molecules have been registered. The number increased regularly with a maximum of 138 in 2002 and only around 100 remain in 2010. The evolution of the number of modes of action available for weed control in wheat is discussed.

Carry over effects of cover crop mixtures and management practices on subsequent crops and weeds in no-till systems

2022

Cover crop (CC) mixtures appear as a promising agroecological tool to suppress weeds andmaintain crop productivity while reducing chemical inputs such as herbicides and nitrogenfertilizers. The weed suppressive effect of CC and CC nitrogen release have been related to CCcomposition, soil resource availability and CC termination methods but the relative effect ofthese factors and their interactions remain poorly documented, especially in the case of CCmixtures. Most studies have focused on the subsequent spring crop, and hence, lacked toinvestigate long-term carry over effects of CC. A two field: year experiment was conducted toinvestigate the effect of CC mixture (2 or 8 species including o…

Simulateur de pulvérisation localisée d’herbicide

2019

Site-specific spraying is a technological lever to reduce the herbicide amount used in the case of chemical control of weeds. At the present time, detection and control technologies are available to apply herbicide only where weeds are present and thus provide an alternative to homogeneous application of chemicals on the entire surface of the field. In order to assess this practice, a digital simulator has been developed combining virtual infestation maps with different theoretical sprayer configurations. Simulations were used to localize herbicide applications and quantify herbicide reduction based on the spatial distribution of weeds and the width of independent spray units (boom sections…

Importance of seeds in the process of common ragweed invasion

2012

International audience; Ambrosia artemisiifolia L. (common ragweed) was introduced into Europe at the end of the 1900s and is now present in several European countries. This annual invasive plant produces seeds that are highly polymorphic. Common ragweed can produce only a few thousand highly viable seeds. Many studies have focused on the seed stage. Greater seedling emergence for the seeds placed near the soil surface could explain the success of this species in open habitats, where the probability of deeper burial is low. Emergence percentage was found to decrease as burial depth increased from 2 to 8 cm, and no germination nor seedling emergence was observed for the seeds buried from 10-…

Weed suppression in cover crop mixtures under contrasted levels of resource availability

2022

Cover crop (CC) mixtures appear as a promising agroecological tool for weed management.Although CC supress weed growth by competing for resources, their suppressive effect undercontrasting levels of soil resource availability remains poorly documented. A two field: yearexperiment was conducted to investigate the weed suppressive effect of four CC mixtures.They were composed of 2 or 8 species including or not legume species and compared to abare soil control. The experiment included two levels of irrigation and nitrogen fertilisation atCC sowing. The objectives were to assess (i) weed and CC aboveground biomass response toCC mixtures and resource availability, (ii) the weed suppressive effec…

Mating system adaptation in populations of Centaurea cyanus L.

2010

International audience; Since the 50s, the agriculture intensification in Western Europe resulted in landscape homogenizationand reduction of habitat connectivity, which in turn caused a widespread decline of farmland biological diversity.Centaurea cyanus is one of the declining “segetal species”. It is an annual and insect-pollinatedspecies with a self-incompatibility system. When the populations are small and fragmented, they mayextinct if the incompatibility system cannot evolve towards a compatibility system. A coexistence ofmixed mating system is also possible in a population.In our study, we examined the ability of C. cyanus to produce seeds by autogamy. For this purpose,three conditi…

Biological causes of cornflower regression

2012

International audience; Agroecosystems are currently experiencing high biodiversity loss. This decline results from intensive cropping systems. However, not all the anciently present weeds respond similarly. There should be specific biological traits that render some species more prone to disappear from arable fields than others. Investigating the biological causes of regression could inform about management strategies in changing agricultural farming systems. In this report we focus on cornflower (Centaurea cyanus) that is an emblem of the flora associated with traditional cereals in Europe. It is currently disappearing from Western regions. Several traits were investigated as seed longevi…

Prévention et gestion de la résistance aux herbicides en grande culture

2017

National audience; L'apparition de mauvaises herbes résistantes aux herbicides a conduit à développer de nouvelles solutions pour gérer la flore adventice. Un des leviers est de diminuer la pression exercée par les molécules herbicides sur les espèces d’adventices en optimisant le désherbage chimique. Cet ajustement doit passer par une alternance des modes d’action des herbicides appliqués sur une parcelle aux échelles annuelle et pluriannuelle. Il peut également passer par des réductions de quantités d’herbicides appliquée à l’échelle de la parcelle en ne traitant que les zones où sont très présentes les mauvaises herbes.

La nuisibilité directe des adventices en grandes cultures : quelles réponses nous apportent les essais désherbages ?

2016

The direct harmful effect of weeds in field crops : what do herbicide trials tell us ? Weeds are plants whose undesirable qualities (“harmfulness") outweigh their desirable qualities (trophic resources). Few studies conclude that weeds do not affect crop yield. However, it is difficult to generalize since weeds compete with crops for resources and these resources are spatially and temporally variable. This study analyzed 110 herbicide trials (untreated vs. treated plots) performed in France from 1993 to 2015 on three major grain crops: winter wheat, winter oilseed rape and sunflower. Significant yield losses were found in 92% of wheat trials (average over all trials: -2.6 t/ha), 51% of wint…

Variability of Christmas rose (Helleborus niger L.) populations and its potential use in genetic breeding

2005

International audience; The Christmas rose (Helleborus niger L.) is widely distributed in Southern and Central Europe, and Slovenia is probably one of the centers of its diversity. The investigation was aimed at evaluating phenotypic diversity among selected wild populations in Slovenia and neighboring Croatia. Some of the analyzed traits expressed relatively very high variation (e.g., number of leaves per plant, number of inflorescences per plant). The variation ranges of some of the analyzed traits were found to be wider than those mentioned in the literature. Statistical analysis indicated that variability was more expressed within than between populations. In terms of present market req…

The adaptation of cornflower in different compartments of the agricultural landscape

2015

International audience; Agrosystems are among habitats most affected by the decline of biodiversity. This decline isrelated to the intensification of agricultural practices carried out since the 50s (simplified rotations,fertilizer and pesticide use; ...). The study of the weed flora shows still less developed plantcommunities. Currently, there is evidence of the regression of the weed flora and especiallyspecies such as cornflower (Cyanus segetum. L). In western Europe, cornflower seems to bepresent in the field only. In our investigation, we tried to determine the factors that influence thepresence of cornflower in the different compartments of a field and its border.

Evaluation of cropping systems for management of herbicide-resistant populations of blackgrass (Alopecurus myosuroides Huds.)

2001

Abstract Simplification of cropping systems often leads to an increase in weed populations which require an intensive use of herbicides to maintain populations at an acceptable level. Due to a heavy reliance on herbicides and a lack of cultural control measures, herbicide-resistant blackgrass (Alopecurus myosuroides Huds.) biotypes appeared recently in France. An experiment was conducted to evaluate the effects of different cropping systems on a population of herbicide-resistant blackgrass. Two crop rotations, one consisting exclusively of winter crops and another including spring crops, were assessed over a three-year period. Crop rotation was combined with different cultural practices (mo…
