The crystal structure of the sodium salt of mesotrione, namely, catena-poly[[sodium-μ3-2-[(4-methane­sulfonyl-2-nitro­phen­yl)carbon­yl]-3-oxo­cyclo­hex-1-en-1-olato] ethanol monosolvate], {[Na(C14H12NO7S)]C2H5OH}n, is described. The X-ray structural analysis results reveal that the coordination sphere is established by two chelating O atoms, the O atom of the coordinated ethanol mol­ecule, and an O atom from the methyl­sulfonyl group of a neighboring mol­ecule. Simultaneously, an O atom of the cyclo­hexane fragment serves as a bridge to a neighboring sodium ion, forming a flat Na–O–Na–O quadrangle, thereby forming a mono-periodic polymer. The structure displays O—H⋯O hydrogen bonds and C—H⋯O short contacts. Thermogravimetric analysis (TGA) data indicate that the sodium salt of mesotrione decomposes in four stages.

The use of herbicides on crops causes environmental concerns. A new French study assesses the performance of cropping systems to manage weeds and finds that these techniques could control arable weeds in the long-term and reduce reliance on herbicides.

A recent study has compared the chemical environmental impacts of using the weed controller glyphosate on glyphosate-tolerant (GT) crops, with the use of other herbicides on non-GT crops. Glyphosate used on GT crops had lower environmental impacts than herbicides used on non-GT crops, but the persistence of AMPA (a break-down product of glyphosate) in soils could be a problem in the future.

The European ban on atrazine has effectively reduced concentrations of the herbicide in coastal waters, a new study has found. However, the researchers also warn that, in some areas, atrazine levels remain relatively high as some countries have not yet restricted use of the chemical.

This study assessed the effects of herbicides on non-target plants in Denmark and Canada. The findings showed that some plants are more sensitive to herbicides in the reproductive stages of their life cycle and can experience delays in flowering and reduced seed production. The authors say future ecological assessments should consider reproductive outcomes.

Herbicides in aquatic environments can have negative consequences on local plant life. This study investigated the effects of glyphosate, one of the most widely used herbicides in the world, on a marine plant species. The herbicide caused significant changes to the plant, reducing the number and chlorophyll content of leaves, and high concentrations were lethal. The authors say use of this chemical may be dangerous to plants in estuaries.

Pesticide-sparing approaches to farming do not have to compromise on crop yields, new research suggests. A study that explored the impact of reduced herbicide use across a variety of different farming contexts found that herbicide-efficient systems could be just as productive as conventional systems — and more so than organic systems — whilst having other important environmental benefits.

Pesticides used on agricultural land can leach into nearby surface water; this is called run-off and can harm aquatic ecosystems. This study evaluated the potential of ditches to reduce run-off, using Italy’s Po Valley as a case study. Grassy ditches were able to significantly reduce the concentration of herbicides, even during extreme flooding. The researchers therefore suggest that the promotion of vegetated ditches via agri-environment schemes would be beneficial for pesticide mitigation.

Glyphosate is a widely used herbicide, able to kill a broad range of plants ('weeds') that compete with crops. This study used a validated method to assess its presence in 10 German estuaries that lead to the Baltic Sea. All but one was contaminated with glyphosate, and all were contaminated with its metabolite AMPA. The researchers recommend risk assessments for these chemicals in the Baltic Sea and other marine environments.

New research suggests that feral oilseed rape poses little risk of contaminating crops, but if the oilseed is genetically modified (GM), it could be a minor source of GM traits in weeds. Throughout Europe, feral oilseed rape is now widespread on waysides and wasteland, making it potentially more problematic than some other crops, such as maize, which do not easily establish feral populations.

To increase timber production and manage other forest resource values, some land managers have undertaken logging debris and vegetation control treatments after forest harvest. We explored the roles of clearcutting on plant community composition and structure at three sites where logging debris was dispersed, piled, or removed and vegetation was annually treated or not treated with herbicides for 5 years. Without vegetation control, a competitive relation was identified between exotic and native ruderal (i.e., disturbance-associated) species. When exotic ruderal cover changed by 4 percent, native ruderal cover changed by 10 percent in the opposite direction. This relation was independent of site, but site was important in determining the overall dominance of ruderals. Five annual vegetation control treatments increased Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) growth, but decreased richness and cover of other species at the rate of one species per 10 percent reduction in cover. Debris treatment effects were small and found on only one site.

The esterfication of hypophosphorous acid is followed by reaction with another molecule of alcohol under the action of a nickel catalyst to provide a green method for the preparation of H-phosphonate diesters. This method avoids the need for any stoichiometric chlorine unlike those based on phosphorous trichloride.
