Experimental evolution of herbicide resistance in chlamydomonas reinhardtii [PDF]

Our understanding of the evolutionary dynamics of selection for herbicide resistance is limited by the time and space required to conduct meaningful selection experiments in higher plants. This constrains the study of the

Effect of water hardness induced by bicarbonate and chloride forms of magnesium and sodium on the performance of herbicides for littleseed canarygrass control

Journal of Crop Protection, 2022
Based on the chemical properties of herbicide and carrier water, water hardness might have different impacts on herbicide performance. A study was conducted in the greenhouse to determine the effect of chloride and bicarbonate forms of Mg+2 and Na+ on ...

Identifying resistance‐conferring cytochrome P450s in weeds: experimental strategies and practical considerations

Pest Management Science, EarlyView.
Identifying resistance‐conferring cytochrome P450s requires integrating weed characterization, gene discovery and functional validation. No single approach is sufficient to distinguish causal resistance genes from herbicide‐metabolizing enzymes. Abstract Cytochrome P450 monooxygenases (P450s) play a pivotal role in metabolic herbicide resistance, yet ...

Social Costs of Herbicide Resistance: The Case of Resistance to Glyphosate [PDF]

Unlike in the pesticide and antibiotic resistance literature, potential social costs and externalities associated with herbicide resistance have not generally been considered by economists.

Mulch Type and Depth, Herbicide Formulation, and Postapplication Irrigation Volume Influence on Control of Common Landscape Weed Species

HortTechnology, 2019
Mulch is often applied in landscape planting beds for weed control, but little research has focused specifically on mulch and preemergence (PRE) herbicide combinations.

Reduced Herbicide Antagonism of Grass Weed Control through Spray Application Technique

Agronomy, 2020
Dicamba and 2,4-D tolerance traits were introduced to soybean and cotton, allowing for over the top applications of these herbicides. Avoiding antagonism of glyphosate and clethodim by dicamba or 2,4-D is necessary to achieve optimum weed control.

Efficacy of herbicides for weed control in chamomile

Lekovite Sirovine
Experiments were conducted to assess the control of weeds with two PRE-EM (pendimethalin and ethofumesate) and one POST-EM (fluroxypyr-meptyl) herbicides used in chamomile. Pendimethalin (990 g a.i. ha-1) and ethofumesate (1000 g a.i. ha-1) were applied after crop sowing but before crop and weed emergence, while fluroxypyr-meptyl (258.48 g a.i.

Characterization of a novel R98Q mutation that confers resistance to sulfentrazone in common ragweed (Ambrosia artemisiifolia) populations from Michigan

Pest Management Science, EarlyView.
Field‐collected Ambrosia artemisiifolia populations from Michigan, USA, soybean fields exhibited strong resistance to the protoporphyrinogen IX oxidase (PPO)‐inhibiting herbicide sulfentrazone and reduced sensitivity to fomesafen. Target‐site analysis identified a novel Arg‐98‐Gln (R98Q) substitution in PPO2, co‐occurring with the previously reported ...

Herbicide mixtures for control of herbicide resistant Apera spica-venti populations

Julius-Kühn-Archiv, 2018
Apera spica-venti is a very important weed in cereal crops throughout Central, Northern and Eastern Europe and herbicide resistance to post-emergence herbicides is often present in A. spica-venti populations.

Absorption and translocation of 14C‐propiconazole associated with two adjuvants in young coffee plants

Pest Management Science, EarlyView.
Experimental workflow evaluating 14C‐propiconazole absorption and translocation in Coffea arabica with two biodegradable adjuvants, quantified at six post‐application time points using radioscanner and liquid scintillation spectrometry. Abstract BACKGROUND This study evaluated the absorption, translocation and distribution of 14C‐propiconazole applied ...
