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 ...

Preemergence signatures of horizontal divergent flows in solar active regions

, 2022
Solar active regions (ARs) play a fundamental role in driving many of the geoeffective eruptions, which propagate into the solar system. However, we are still unable to consistently predict where and when ARs will occur across the solar disk by ...

Efficacy of preemergence herbicides over time [PDF]

Journal of Environmental Horticulture, 2019
Abstract Preemergence herbicides are applied to container-grown nursery crops repeatedly throughout the year, often in 8 to 10 week intervals. Preemergence herbicide efficacy may decline over time, resulting in reduced weed control several weeks after application if weed seed density remains high.
