La problématique de l’utilisation des herbicides en foresterie: le cas du Québec

open access: yesVertigO, 2005
Herbicide use in forestry is analysed from an historical and  environmental perspective. First chemical herbicides were developed during the Second World War.

Deep Learning Techniques for In-Crop Weed Identification: A Review [PDF]

open access: yes, 2021
Weeds are a significant threat to the agricultural productivity and the environment. The increasing demand for sustainable agriculture has driven innovations in accurate weed control technologies aimed at reducing the reliance on herbicides. With the great success of deep learning in various vision tasks, many promising image-based weed detection ...

Top-down Green-ups: Satellite Sensing and Deep Models to Predict Buffelgrass Phenology [PDF]

open access: yesarXiv, 2023
An invasive species of grass known as "buffelgrass" contributes to severe wildfires and biodiversity loss in the Southwest United States. We tackle the problem of predicting buffelgrass "green-ups" (i.e. readiness for herbicidal treatment). To make our predictions, we explore temporal, visual and multi-modal models that combine satellite sensing and ...

How a simple chloroplast psbA gene mutation changed world agriculture [PDF]

open access: yesarXiv, 2023
Atrazine as a weed control tactic profoundly changed world agriculture. Long-term use revealed resistant biotypes, R, with a single base pair mutation of the chloroplast psbA gene. The R phenotype emerged from a sequential cascade of pleiotropic effects from the plastid to the whole plant.

Saffron Crocus sativus L. tolerance to some herbicides

open access: yesJournal of Crop Protection, 2020
Although, weed control in saffron farms is critical, no herbicide is registered for saffron fields. This experiment was carried out in a randomized complete block design with three replicates during 2016-2017.

Dactyloctenium aegyptium (L.) Willd. (Poaceae) Differentially Responds to Pre- and Post-Emergence Herbicides through Micro-Structural Alterations

open access: yesAgriculture, 2022
Herbicides are widely used to kill weeds and increase crop production all over the world. Nevertheless, some weeds show certain structural modifications in response to herbicide application that impart mostly partial or sometimes complete tolerance to ...

Turfgrass Herbicides: Mechanisms of Action and Resistance Management

open access: yesEDIS, 2015
Herbicides are an effective tool for controlling weeds in turfgrass; however, weeds can become resistant to herbicides and create significant problems for turfgrass production.

Tricolorin A as a Natural Herbicide [PDF]

open access: yesMolecules, 2013
Tricolorin A acts as pre- and post-emergence plant growth inhibitor. In pre-emergence it displays broad-spectrum weed control, inhibiting germination of both monocotyledonous (Lolium mutliflorum and Triticum vulgare) and dicotyledonous (Physalis ixocarpa and Trifolium alexandrinum) seeds, being the dicotyledonous seeds the most inhibited. Tricolorin A

The tetrazole analogue of the auxin indole-3-acetic acid binds preferentially to TIR1 and not AFB5 [PDF]

open access: yes, 2018
Auxin is considered one of the cardinal hormones in plant growth and development. It regulates a wide range of processes throughout the plant. Synthetic auxins exploit the auxin-signalling pathway and are valuable as herbicidal agrochemicals. Currently, despite a diversity of chemical scaffolds all synthetic auxins have a carboxylic acid as the active ...
