Integrated effect of row spacing and herbicide programs on photosynthetically active radiation, control, and seed production of multiple herbicide‐resistant Palmer amaranth in corn

Agrosystems, Geosciences &Environment, Volume 8, Issue 1, March 2025.
Abstract Multiple herbicide‐resistant (MHR) Palmer amaranth has been ranked as the most problematic weed in row crop fields in Nebraska. Integration of narrow row spacing with herbicide might augment control of MHR Palmer amaranth. The objectives of this study were to evaluate an integrated effect of row spacing and herbicide programs for MHR Palmer ...

Pattern of herbicide multi‐resistance in annual ryegrass (Lolium rigidum Gaud.) weedy populations across Southeast Australia

Weed Research, Volume 65, Issue 2, March/April 2025.
Abstract Herbicide resistance to multiple chemistries increasingly erodes chemical management options for agricultural weeds. Regular surveys for herbicide resistance in weed populations are critical to assess patterns and rates of resistance development. Resistance in annual ryegrass across Southeast Australia has been monitored for over three decades,

Dose-response of common lambsquarters, redroot pigweed, and foxtail species to pyroxasulfone plus encapsulated saflufenacil applied preemergence to corn

Weed Technology
In September 2024, BASF Canada introduced a new premixture of pyroxasulfone and encapsulated saflufenacil to control weeds in corn production. Limited research has been conducted to determine the biologically effective dose of this new premixture for the

Can biostimulants and tillage rotations improve dryland crop productivity and soil microbes?

Agronomy Journal, Volume 117, Issue 1, January/February 2025.
Abstract Soil microbes are essential for soil nutrient cycling. However, frequent tillage and the use of synthetic agrochemicals can reduce soil microbial diversity and enzyme activity. In this study, the effects of four tillage treatments (mouldboard plough, shallow tine‐tillage, no‐tillage, and tillage rotation) and two rates of synthetic ...

Cover crops and fall residual herbicides for managing Italian ryegrass

Weed Technology
North Carolina growers have long struggled to control Italian ryegrass, and recent research has confirmed that some Italian ryegrass biotypes have become resistant to nicosulfuron, glyphosate, clethodim, and paraquat.
