The potential for improvedmanagement of Cercospora leaf spot (CLS), caused by Cercospora beticola, using the herbicide glyphosate in glyphosate-resistant sugar beet varieties was investigated. Controlled field experiments were conducted in 2008 and 2009 to determine if glyphosate and glyphosateefungicide combinations improved the management of CLS in four commercial varieties of glyphosate-resi...

Resistance to herbicides in arable weeds is increasing rapidly worldwide and threatening global food security. Resistance has now been reported to all major herbicide modes of action despite the development of resistance management strategies in the 1990s. We review here recent advances in understanding the genetic bases and evolutionary drivers of herbicide resistance that highlight the comple...

Two-year field dissipation studies were conducted in three soil types in Minnesota to examine the processes affecting the dissipation of the herbicide isoxaflutole and its phytotoxic diketonitrile metabolite (DKN) under relatively cool, wet soil conditions. Plots of cuphea were treated with isoxaflutole and potassium bromide, a nonsorbed, nondegraded tracer. Replicate soil cores were collected ...

Glyphosate herbicide is one the most toxic pollutants for aquatic ecosystem. Changes in serum concentrations of growth hormone (GH) and muscle protein content in O. niloticus treated with different concentrations of glyphosate herbicide under laboratory conditions were evaluated. Nile tilapia Oreochromis niloticus (mean initial weight of 57.61 ± 4.8g and initial length 14.87±1.7cm) were exposed...

This paper presents a systematic diagnostic approach towards the characterization of herbicide resistance in a given weed population with regards to profile (single, multiple, cross resistance), magnitude (fold level), mechanism, and related bio-physiological aspects. Diagnosing herbicideresistant weeds can be achieved by crafting robust procedures for seed sampling, survey protocol and seed co...

It is well known that delayed fluorescence (DF) from Photosystem II (PSII) of plant leaves can be potentially used to sense herbicide pollution and evaluate the effect of herbicides on plant leaves. The research of using DF as a measure of herbicides in the literature was mainly conducted in time domain and qualitative correlation was often obtained. Fourier transform is often used to analyze s...

the effect of tillage (conventional and zero tillage), crop establishment (raised-bed and flat-bed), and weed management practices (herbicide alone and integrated approach) was studied on productivity, profitability, nutrient uptake and physico-chemical properties of soil in soybean–wheat cropping system, at new delhi during 2010–2012. sixteen treatment combinations consisting of four tillage a...

Synthetic herbicides have been used globally to control weeds in major field crops. This has imposed a strong selection for any trait that enables plant populations to survive and reproduce in the presence of the herbicide. Herbicide resistance in weeds must be minimized because it is a major limiting factor to food security in global agriculture. This represents a huge challenge that will requ...

the silica gel waste (sgw), after its collection from a local factory (kolkata, india) was modified with cationic surfactant and was utilized as an adsorbing media for the removal of 2,4- dichlorophenoxyacetic acid (2,4-d) from agricultural runoff of a tea garden. characterization of base adsorbent and modified adsorbent was carried out. the efficacy of the adsorbent was evaluated through both ...

The objective of this paper is to outline the current use of herbicide-resistant soybean and corn in the United States and describe the ramifications of utilizing these crops derived from biotechnology. The popular press and news articles detail the positions of consumers, environmental advocates, and the agriculture industry. Recent concerns expressed by consumers throughout the world have aff...
