  • One Year Later · Persistent Herbicides in Compost

    ONE YEAR has passed since the Washington State University (WSU) composting facility and the Spokane Regional Compost Facility discovered traces of persistent herbicides in their composts. In Spokane, the source of contamination is a compound called clopyralid. Compost contamination at WSU initially involved the herbicide picloram, but clopyralid has since been detected in the compost also. In ...


  • Trend of herbicide loads in the river Rhine and its tributaries

    Many policies have been established and actions have been taken to reduce pesticide pollution of surface waters. However, the effectiveness of these initiatives was rarely tested on an empirical basis. This study suggests that evidence on the policy effects can be evaluated by analyzing the temporal changes in the loads rather than the concentrations of active ingredients in rivers. It is shown ...

  • The herbicide atrazine induces hyperactivity and compromises tadpole detection of predator chemical cues

    The ability to detect chemical cues is often critical for freshwater organisms to avoid predation and find food and mates. In particular, reduced activity and avoidance of chemical cues signaling predation risk are generally adaptive behaviors that reduce prey encounter rates with predators. Here, we examined the effects of the common herbicide atrazine on the ability of Cuban tree frog ...

  • Preplant herbicides don`t increase forage production of cereal rye interseeded into bermudagrass

    Interseeding cereal rye (Secale cereale L.) into a bermudagrass sod [Cynodon dactylon (L.) Pers.] can increase season-long forage production and land use efficiency. However, previous research has shown that competition from the bermudagrass sod can significantly reduce autumn forage production from cereal rye. Our objective was to determine if the application of a preplant herbicide to a ...

  • A silviculture application of the glyphosate‐based herbicide Visionmax to wetlands has limited direct effects on amphibian larvae

    Herbicides are commonly used in agriculture and silviculture to reduce interspecific competition among plants and thereby enhance crop growth, quality, and volume. Internationally, glyphosate‐based herbicides are the most widely used herbicides in both of these sectors. Laboratory and mesocosm studies have demonstrated that some formulations are toxic to amphibian larvae below concentrations ...

  • Agrochemicals in field margins—assessing the impacts of herbicides, insecticides, and fertilizer on the common buttercup (Ranunculus acris)

    The effects of herbicide, insecticide, and fertilizer inputs on the common buttercup Ranunculus acris in field margins were studied in an experimental field study. The test design allowed us to investigate the single and combined effects of repeated herbicide, insecticide, and fertilizer applications in successive growing seasons. To assess the effects of the agrochemical applications on R. ...

  • Analysis of Selected Herbicides And Related Metabolites in a Coastal Lagoon Under The Influence of Water Runoff: Sediment and Biota

    Coastal lagoons are subjected to strong anthropogenic pressures as a consequence of their location between Land and Sea. Among other contaminants, they are receiving high nutrient loadings and pesticides, mainly of agricultural origin, from heavily exploited watersheds. Since the number of chemicals released into the water systems is high, there is a need to classify them and the associated risk, ...


  • Using Compost To Control Plant Diseases

    Losses due to soilborne diseases on some greenhouse, nursery and vegetable crops can amount to thousands of dollars per acre annually. Until the 1930s, organic amendments — consisting of animal and green manures, coupled with crop rotation — were principal methods of control. But these approaches were largely abandoned for reasons of cost and inconvenience after commercial fertilizers and the ...

  • Control of cereal rye with a roller/crimper as influenced by cover crop phenology

    Adoption of reduced tillage practices have been driven by the need to enhance soil quality, minimize field labor time, and scale up farm size. However, concerns about increased reliance on herbicides and demand for organically grown foods call for adoption of production practices that can reduce both tillage and herbicide use. This research study assessed the influence of planting and termination ...

  • Pilot Test for Dinoseb Reduction at an Agricultural Facility

    Site Summary Dinoseb (2-sec-butyl-4,6-dinitrophenol) is a phenolic herbicide used on soybeans, vegetables, fruits and nuts, citrus,and other field crops for the selective control of grass and broadleaf weeds. It is also used as an insecticide in grapes,and as a seed crop drying agent. In 1986 dinoseb was banned as a commercially available product in the U.S. becauseof the potential ...

  • Pesticides in the European Union

    There has been a sharply falling trend in the total volume of sales of agricultural pesticides in the EU between 1991 and 1995. But this was reversed in 1996. From 1991-1995, EU sales of pesticides, measured by weight of active ingredients (ai), fell by 13%. They then rose by 6% between 1995 and 1996 to stand at 299,826 tonnes ai. But this still put them nearly 8% below the 1991 figure. The use ...

  • Weed biomass and species composition as affected by an integrated crop–livestock system

    Crop and livestock production are rarely integrated together in modern farming systems. Reintegrating crops with livestock production has been shown to produce many agronomic and environmental benefits.
