“…A contemporary example is genetic engineering for disease resistance, which is now feasible for some pathosystems, and is a technology available in many countries but restricted in Europe. At the same time, tighter rules around chemical pesticides will result in fewer pesticides being available to control many pathogens on crops such as cereals and potatoes [34,35]. The consequence is that disease control in Europe can depend less on technological fixes and must rely more on preventative actions to reduce and contain the risk of disease spread.…”

Plant diseases threaten both food security and the botanical diversity of natural ecosystems. Substantial research effort is focused on pathogen detection and control, with detailed risk management available for many plant diseases. Risk can be assessed using analytical techniques that account for disease pressure both spatially and temporally. We suggest that such technical assessments of disease risk may not provide an adequate guide to the strategies undertaken by growers and government to manage plant disease. Instead, risk-management strategies need to account more fully for intuitive and normative responses that act to balance conflicting interests between stakeholder organizations concerned with plant diseases within the managed and natural environments. Modes of effective engagement between policy makers and stakeholders are explored in the paper, together with an assessment of such engagement in two case studies of contemporary non-indigenous diseases in one food and in one non-food sector. Finally, a model is proposed for greater integration of stakeholders in policy decisions.

“…Pesticides used in agriculture present a particularly important environmental threat due to their ecotoxicity which stems naturally from their purpose (Reichenberger et al, 2007;Buchanan et al, 2011). MCPA, a systemic herbicide used for the post-emergence control of broad-leaf weeds (Tomlin, 1994), is such an example of an agricultural pesticide that is commonly found in waters and soil (Silva et al, 2006;Köck et al, 2010;Botta et al, 2012;Matamoros et al, 2012a).…”

H I G H L I G H T S• CW with LECA substrate and Phragmites plants tested with agricultural wastewaters.• High removals of TSS, COD, NH 4 -N, polyphenols, a pharmaceutical and a pesticide.• Contact time of wastewaters with beds ranged from 3 to 9days in batch conditions.• Promising results suggest more studies in full-scale and more realistic conditions. Constructed wetlands (CWs) are receiving a renewed attention as a viable phytotechnology for treating agricultural wastewaters and for the removal of more specific pollutants, in particular recalcitrant ones. In this work, the performance of CW mesocosms using light expanded clay aggregates (LECA) as the bed's substrate and planted with Phragmites australis was investigated for treatment of olive mill wastewater (OMW), swine wastewater (SW) contaminated with oxytetracycline and water contaminated with herbicide MCPA (2-methyl-4-chlorophenoxyacetic acid). Both wastewaters (OMW and SW) initially presented high organic matter content and total suspended solids which were removed by the system with efficiencies higher than 80%. Removal of polyphenols in OMW and nitrogen compounds in SW also showed similar or higher efficiencies in comparison with other treatment systems reported in the literature. The antibiotic oxytetracycline was completely removed from SW within the assay period in unplanted LECA beds, but planted beds allowed a significantly faster removal. In regard to water contaminated with MCPA, the results showed that LECA has a large sorption capacity for this herbicide (removal efficiencies of 56-97%). In general, considerably higher pollutant removal efficiencies were obtained when plants were used (up to 28% higher). The results obtained are indicative that CWs with LECA as substrate may be an adequate option for agricultural wastewater treatment. a b s t r a c t a r t i c l e i n f o

“…Extensive use of herbicides poses some far-reaching consequence because of the potential runoff and leaching of these compounds through the soil leading to contamination of surface and ground water [6]. Apart from this, literature suggests an array of possible toxicological implications of the persisted herbicides on the ecosystem [7]. As a result, a wealth of research has been published on the occurrence, fate, and effects on human health and environment from the use of herbicides in weed control [8,9].…”

Biostimulation for the Enhanced Degradation of Herbicides in Soil

Cleanup of herbicide-contaminated soils has been a dire environmental concern since the advent of industrial era. Although microorganisms are excellent degraders of herbicide compounds in the soil, some reparation may need to be brought about, in order to stimulate them to degrade the herbicide at a faster rate in a confined time frame. "Biostimulation" through the appropriate utilization of organic amendments and nutrients can accelerate the degradation of herbicides in the soil. However, effective use of biostimulants requires thorough comprehension of the global redox cycle during the microbial degradation of the herbicide molecules in the soil. In this paper, we present the prospects of using biostimulation as a powerful remediation strategy for the rapid cleanup of herbicide-polluted soils.
