Herbicide Application Rates: Risk Premiums with Environmental Implications [PDF]
This paper examines the role of risk aversion in setting herbicide label rates and application rates. Companies establish label rates to be efficacious for a wide range of conditions.

Do spatially targeted weed management strategies increase risk of herbicide resistance evolution?
Pest Management Science, EarlyView.Spray‐buffers reduce the effect of detection inaccuracies in spot spraying. We found a trade‐off between short‐term weed population control efficacy and long‐term prevention of herbicide resistance evolution. Abstract Background Spatially targeted spraying is an alternative to broadcast herbicide application that reduces herbicide use by restricting ...

Assessment of insecticide use practices in licensed pest control operators in North Carolina
Pest Management Science, EarlyView.A statewide survey of 105 licensed North Carolina pesticide operators found ants, mosquitoes, and aphids as top target pests, pyrethroids as the dominant insecticide class (68%), and limited resistance monitoring, establishing a baseline for future insecticide resistance management and outreach.

The continuing significance of chiral agrochemicals
Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Grass Herbicide Efficacy as Influenced by Adjuvant, Spray Solution pH, and Ultraviolet Light
, 1996 Research was conducted at the Brandon Research Centre to determine the effect of spray solution pH or adjuvants on the efficacy of two cyclohexanedione (CHD) herbicides, clethodim and tralkoxydim, and two aryloxyphenoxypropionate (APP) herbicides ...

Herbicide efficacy in relation to herbicide rate, surfactant rate and spray application volume
Proceedings of the New Zealand Plant Protection Conference, 1999 In two experiments, a central composite response surface design was used to investigate the interactions between herbicide rate (glyphosate in Experiment 1 and metsulfuron in Experiment 2), surfactant rate, and spray application volume on tomato dry weight production.

Responsive Materials, EarlyView.Environmental pollution and water scarcity demand innovative purification methods. This study presents a sol‐gel approach to fabricate mixed silica–titania thin films joining photocatalytic activity with selective sorption capability. The films exhibit higher surface area, enhanced degradation of cationic and improved performance over bare titania ...
