  • Maximising herbicide efficiency - Case Study

    The most important component in achieving an effective and efficient spray solution will always be the water source, so in hard water areas, using a good quality water conditioner is essential to prevent chemical breakdown and maximise herbicide performance. Around the country water can range from soft to hard and its pH can also vary depending on location. From Yorkshire down ...

  • Photo-assisted electrochemical degradation of the commercial herbicide atrazine

    This paper presents a degradation study of the pesticide atrazine using photo-assisted electrochemical methods at a dimensionally stable anode (DSA®) of nominal composition Ti/Ru0.3Ti0.7O2 in a prototype reactor. The effects of current density, electrolyte flow-rate, as well as the use of different atrazine concentrations are reported. The results indicate that the energy consumption is ...

  • Quantifying vapor drift of dicamba herbicides applied to soybean

    Recent advances in biotechnology have produced cultivars of corn, soybean, and cotton resistant to the synthetic‐auxin herbicide dicamba. This technology will allow dicamba herbicides to be applied in new crops, at new periods in the growing season, and over greatly expanded areas, including postemergence applications in soybean. From past and current use in corn and small grains, dicamba vapor ...

  • 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 ...


  • Herbicides Confidential Client, Ontario, Canada (Metolachlor)

    Ontario, Canada Project Treatment of Soil Impacted by Chlorinated Pesticides Summary This project was the second of three pilot scale projects within a research and development program designed to validate certain DARAMEND® applications on chlorinated pesticide impacted soil. The Challenge Treatment of 250 tons of soil ...


  • 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 ...

  • Herbicides Confidential Client, Ontario, Canada (2,4-D and 2,4,5-T)

    Ontario, Canada Project Pilot-Scale demonstration on soil containing phenoxy-acid herbicides (2,4-D, and 2,4,5-T), and other chlorinated pesticides (DDT, DDD, and DDE) Summary The application of DARAMEND® served to reductively de-chlorinate, and subsequently mineralize the chlorinated herbicides and pesticides. The Challenge ...


  • Effects of the herbicide dicamba on non‐target plants and pollinator visitation

    Nearly 80% of all pesticides applied to row crops are herbicides, and these applications pose potentially significant ecotoxicological risks to non‐target plants and associated pollinators. In response to the widespread occurrence of weed species resistant to glyphosate, biotechnology companies have developed crops resistant to the synthetic‐auxin herbicides dicamba or 2,4‐D, and once ...

  • Effects of low levels of herbicides on prairie species of the Willamette Valley, Oregon

    The relative sensitivity of 17 non‐crop plant species from Oregon's Willamette Valley was determined in response to glyphosate, tribenuron methyl (tribenuron) and fluazifop‐P‐butyl (fluazifop) herbicides. For glyphosate; Elymus trachycaulus, Festuca arundinacea, Madia elegans, Potentilla gracillis and Ranunculus occidentalis were the most sensitive species, based on a concentration calculated ...

  • 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 ...

  • Pesticide destruction in agrochemical wastewater with DiaCell® - Technology

    Chemicals commonly called pesticides (herbicides, insecticides) are extensively used in farming to increase yields and protect crops. These products are very efficient but they are also very toxic. Pesticides may have ecological effects or be toxic for various terrestrial and aquatic animals and plants. These effects may be due both to the pesticide itself as well as its breakdown products. The ...
