Effects of glyphosate and clethodim alone and in mixture in sourgrass (Digitaria insularis)
Crop Protection, 2020 Abstract Glyphosate is used frequently in agriculture, and sourgrass (Digitaria insularis (L.) Mez ex Ekman) has become one of the most problematic weeds in Brazil because of its resistance to this herbicide. One of the alternatives for sourgrass control is the use of graminicide alone or in mixture with glyphosate. Thus, this experiment was aimed at

Thirty years of glyphosate-resistant crops and weeds: Current situation and future prospects. [PDF]
Pest Manag SciSince 1996, when the first glyphosate‐resistant crop was commercialized and the first resistant weed was reported, resistance has expanded globally. This review analyzes emergence patterns across weed species, crops, regions, resistance mechanisms, and herbicides.

Insights into ALS-inhibiting herbicide resistance in Poa annua in an arable cropping system. [PDF]
Pest Manag SciVariable cross‐resistance to ALS inhibitors in five Poa annua populations from wheat fields in Ireland caused by different TSR mutations. Abstract BACKGROUND Dependence on a single herbicide type to control a broad‐spectrum of weeds has resulted in cases of resistance to acetolactate synthase (ALS) inhibitors in weeds normally considered lower priority

Development of cytosine and adenine base editors for maize precision breeding. [PDF]
J Integr Plant BiolA series of maize cytosine and adenine base editors was developed using various deaminase variants, enabling efficient multiplex genome editing in maize. Precise editing of the ZmACC1/2 genes generated herbicide‐tolerant maize germplasm, offering a solution for weed management in maize‐soybean intercropping systems.

Poa annua becomes the first weed to evolve resistance to indaziflam applied preemergence and early-postemergence. [PDF]
Pest Manag SciWe report the first confirmed global case of Poa annua evolving resistance to indaziflam applied both preemergence and early‐postemergence. Resistance intensified under cool temperatures, was not reversed by metabolic inhibitors, and was often linked to multiple resistance, underscoring urgent needs for integrated weed management.

ACCase inhibitor fractionation and glyphosate addition improve perennial sourgrass control
Semina: Ciências Agrárias, 2022 Glyphosate-resistant sourgrass is difficult to control, particularly when perennial, and strategies that improve the control efficiency against this grass and preserve the useful life of graminicides are warranted.

Source-sink relationships of wheat plants obtained by the application of systemic herbicides [PDF]
Pesquisa Agropecuária Brasileira, 2021 : The objective of this work was to evaluate the potential of solute translocation among stems of wheat (Triticum aestivum), by the application of the systemic herbicides clethodim and glyphosate. The experiments were carried out in greenhouse conditions,

Pesticide prioritization based on risk and model diet proposals for assessing cumulative exposure to pesticide residues in the Brazilian population through food consumption. [PDF]
Pest Manag SciA risk classification of registered pesticides in Brazil was conducted, and the contribution of food to cumulative pesticide exposure was evaluated. Model diets were proposed, based on Brazilian consumption patterns. Abstract BACKGROUND Pesticide residue exposure assessments can be carried out during both the pre‐regulation and post‐regulation phases ...

Tolerance of Fine Fescues to Clethodim [PDF]
HortScience, 1997 Fine fescues are immune to two common graminicides, fluazifop-p-butyl and sethoxydim. This study was initiated to determine the tolerance of three fine fescues; chewings, hard, and creeping red, to clethodim alone or with a crop oil concentrate (COC) or non-ionic surfactant (NIS). Clethodim at 0.25 or 1.0 lb/a was applied on 23 Oct.
