Phosphorus fertilizer impacts on sweetpotato yield and nutrient dynamics in the soil, roots, and leaves

Soil Science Society of America Journal, Volume 89, Issue 5, September/October 2025.
Abstract Phosphorus (P) is a macronutrient influencing soil fertility and nutrient dynamics. To investigate the effects of phosphorus application on soil nutrient availability and sweetpotato (Ipomoea batatas [L.] Lam) productivity, a 3‐year field experiment was conducted using cultivars Beauregard B14 and Orleans in Pontotoc, MS.

Ecotoxicological effects of commercial herbicides on the reproductive system of aquatic arthropod Limnocoris submontandoni (Hemiptera: Naucoridae)

Brazilian Journal of Biology, 2021
Worldwide, conventional agriculture makes extensive use of pesticides. Although the effects of herbicides are relatively well known in terms of environmental impacts on non-target organisms, there is very little scientific evidence regarding the impacts ...

Unraveling the Role of P450 Reductase in Herbicide Metabolic Resistance Mechanism

Plant Direct, Volume 9, Issue 8, August 2025.
ABSTRACT Plants require cytochrome P450 reductase (CPR) to supply two electrons for cytochrome P450 monooxygenase enzymes (P450) to react with an organic substrate. The transfer of electrons to the P450 active site in the P450 catalytic site relies on a robust and intricate CPR:P450 complex in the endoplasmic reticulum membrane.

Soil residual activity of tetflupyrolimet and the influence of soil moisture and flood timeliness on barnyardgrass efficacy

Weed Technology
Tetflupyrolimet is the first herbicide with a novel site of action to be commercialized for use in agronomic crops in three decades. Direct-seed rice field experiments were conducted at research facilities near Stuttgart (silt loam), AR, and Keiser (clay)

An Urban Stormwater Contaminant Signature: Defining Priority Contaminants for Urban Stormwater Research

Water Environment Research, Volume 97, Issue 7, July 2025.
We identified a core suite of frequently detected contaminants in urban stormwater ponds using three complementary sampling methods. This urban stormwater contaminant signature (USCS) highlights cumulative exposures in pond ecosystems and supports more targeted monitoring of urban runoff.
