Weed control in organic farming
Probably the most cost-intensive and time-consuming operation in organic farming is the elimination of weeds at different stages of plant development. Due to the impossibility of herbicides application, the processing must be performed mechanically. For this purpose farmers use a wide variety of rotary and striegel harrows, cultivators and tillers for interrow processing and ...

The effects of single and multiple applications of glyphosate or aminopyralid on simple constructed plant communities
To determine effects of multiple applications of herbicides on small constructed plant communities, Prunella vulgaris L.var. lanceolata Fern, Festuca roemeri (Pavlick) Alexeev, Clarkia amoena (Lehm.) Nels. and Cynosurus echinatus L. were grown together in small field plots. Plants were treated with glyphosate at target concentrations of 0, 0.01, 0.1, and 0.2 x a field application rate (FAR) of ...

Effects of the herbicide topogard on soil respiration, and denitrification in potato-cultivated soils differing in pH
We investigated the effects of Topogard 50 WP (3 kg ha–1) on soil respiration, mineral N content, and number of denitrifying and total bacteria in four coarse-textured volcanic soils for 91 days. Topogard application decreased CO2 evolution in acid soils (Tepedibi and Karaçakl) whereas soil respiration was initially increased in neutral and alkaline soils (Kaba and Balar). The herbicide ...

The direct and indirect effects of a glyphosate‐based herbicide and nutrients on Chironomidae (Diptera) emerging from small wetlands
Laboratory and mesocosm experiments have demonstrated that some glyphosate‐based herbicides can have negative effects on benthic invertebrate species. Although these herbicides are among the most widely used in agriculture, there have been few multiple‐stressor, natural system based investigations of the impacts of glyphosate‐based herbicides in combination with fertilizers on the emergence ...

Heritability estimates for turfgrass performance and stress response in zoysia spp.
Zoysiagrasses (Zoysia spp.) are widely adapted and highly variable; however, information is lacking regarding the heritability and potential for improvement of numerous performance characteristics. Three individual replicated field studies, which included 90 very fine, 108 fine, and 126 coarse-textured zoysiagrass genotypes, respectively, were conducted near Gainesville, FL, to determine the ...

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 ...

No-tillage improves broomrape control with Glyphosate in Faba-Bean
Broomrape (Orobanche crenata Forsk.) causes considerable losses in faba-bean (Vicia faba L.) production in the Mediterranean region. The application of an ultra-low glyphosate rate at an early broomrape parasitic phase, i.e., tubercle development, is the most common control system. This study sought to determine the effect of tillage system and glyphosate application on broomrape infestation, ...

Evaluation of the management practice for controlling herbicide runoff from paddy fields using intermittent and spillover-irrigation schemes
Two water management practices, an intermittent irrigation scheme using automatic irrigation system(AI) and a spillover-irrigation scheme (SI), were compared for the fate and transport of commonly used herbicides, mefenacet (MF) and bensulfuron-methyl (BSM) in experimental paddy plots. Maximum mefenacet concentrations in paddy water were 660 and 540 µgL−1 for AI and SI plot, respectively. ...

Potential for delayed orchardgrass seeding during glyphosate-resistant alfalfa establishment
Few herbicides are labeled for weed control when establishing alfalfa (Medicago sativa L.)-grass mixtures. Varying the planting date of the grass in relation to alfalfa and adjusting herbicide application timing could improve weed control and forage grass safety. The research objective was to evaluate the use of glyphosate [N-(phosphonomethyl) glycine] for weed control in seedling ...

Effects of the herbicide imazapyr on juvenile Oregon spotted frogs
Conflict between native amphibians and aquatic weed management in the Pacific Northwest is rarely recognized because most native stillwater‐breeding amphibian species move upland during summer, when herbicide application to control weeds in aquatic habitats typically occurs. However, aquatic weed management may pose a risk for aquatic species present in wetlands through the summer, such as the ...

Nitrogen contribution from red clover for corn following wheat in western Ohio
Inclusion of a winter legume cover crop into a crop rotation has been suggested as a method to provide a substantial portion of the N requirement of the following crop. While the benefits of winter cover crops such as reduced soil erosion, increased soil organic matter, and increased mulch cover have been well documented, the N contribution to the subsequent crop has shown to be variable. The ...

Potential risks to freshwater aquatic organisms following a silvicultural application of herbicides in Oregon's Coast Range
Glyphosate, aminomethylphosphonic acid (AMPA), imazapyr, sulfometuron methyl (SMM), and metsulfuron methyl (MSM) were measured in streamwater collected during and after a routine application of herbicides to a forestry site in Oregon's Coast Range. Samples were collected at three stations: HIGH at the fish/no‐fish interface in the middle of the harvest/spray unit; MID at the bottom of the ...

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 ...

Glyphosate-based herbicides on weeds management and maize performance under conservation agriculture practices in eastern Kenya
A three-season research study was conducted at Embu Agricultural Research Station farm to determine the effect of glyphosate-based herbicides on weeds management and maize ( Zea mays L. ) performance under zero-tillage conservation agriculture practice. Glyphosate herbicide sprays were prepared from Roundup Turbo product at the rate of 2.5 L ha –1 and Roundup Weathermax at 1.5, 2.5 and 3.0 L ...

Spatial variability of Atrazine and Metolachlor dissipation on dryland no-tillage crop fields in Colorado
An area of interest in precision farming is variable-rate application of herbicides to optimize herbicide use efficiency and minimize negative off-site and non-target effects. Site-specific weed management based on field scale management zones derived from soil characteristics known to affect soil-applied herbicide efficacy could alleviate challenges posed by post-emergence precision weed ...

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. ...

ASA Survey Shows Herbicide Strategy Compliance Difficult for Farmers
The Environmental Protection Agency has proposed several pesticide registration plans that could significantly affect farmers’ abilities to utilize herbicides. EPA is responsible for approving registrations on pesticides in the United States and has consistently been found by courts to have not properly evaluated the registrations’ effects on endangered species. In order to meet ...
