Targeted herbicide cost requirements for adoption of See & Spray technology and ways to improve area sprayed

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Adopting targeted herbicide applications creates a dynamic problem for producers when considering the economic viability of See & Spray. Research was conducted to estimate how weed area, area sprayed, nozzle selection, sensitivity settings, crops, and regions influence potential herbicide savings with the John Deere See & Spray technology ...

Optimizing unmanned aerial vehicle–based stand counts in soybean: Effects of flight timing, altitude, and analytical method

Agronomy Journal, Volume 118, Issue 1, January/February 2026.
Abstract The accurate estimation of soybean (Glycine max) stand establishment is essential for evaluating crop emergence and informing early‐season management practices. Recent advances in unmanned aerial vehicle (UAV) imagery and computer vision offer opportunities to automate plant population assessments; however, limited information exists on their ...

Integrating early spring‐planted barley or oat for Palmer amaranth management in soybean

Crop Science, Volume 66, Issue 1, January/February 2026.
Abstract Fall‐planted cover crops (CCs) are widely used for weed suppression, but CC establishment challenges after fall harvest in temperate regions necessitate alternative approaches. The objectives of this study were to evaluate the integrated effect of spring‐planted barley or oat CC and herbicide programs for CC biomass production, Palmer amaranth

Pea and canola enrich distinct rhizosphere bacterial communities even under intercropping

Ecosphere, Volume 17, Issue 1, January 2026.
Abstract Microorganisms have implications for plant health and agricultural production, yet we are just beginning to understand the complexity of plant–microbe interactions in multispecies environments. Studies conducted to date have shown that plants are able to control the makeup of their microbial communities, yet their ability to control these ...

Poa annua becomes the first weed to evolve resistance to indaziflam applied preemergence and early‐postemergence

Pest Management Science, Volume 82, Issue 1, Page 539-551, January 2026.
We 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.

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

CONTROL OF VOLUNTARY CORN WITH DOSES OF POST-EMERGENT GRAMINICIDES APPLIED AT DIFFERENT PHENOLOGICAL STAGES

Colloquium Agrariae, 2020
The occurrence of voluntary corn has been common in Brazilian crops, due to the adoption of a succession of soybean and corn crops resistant to glyphosate. The aim of this work was to evaluate the control of voluntary corn using different doses of acetyl-
