Combined impact of aerification, postemergence herbicides, and post‐herbicide irrigation on goosegrass control in bermudagrass putting greens

Agronomy Journal, Volume 117, Issue 1, January/February 2025.
Abstract Goosegrass [Eleusine indica (L.) Gaertn.] is a difficult‐to‐control grassy weed occurring in compacted soils or heavy‐traffic areas including golf greens. In Florida, goosegrass survives as a short‐lived perennial, and eradication becomes more challenging as the plant matures. Currently, only foramsulfuron (FOR) is registered for postemergence

Registration of Tx3499–Tx3503 sorghum germplasm resistant to acetyl‐coenzyme A carboxylase‐inhibiting herbicides

Journal of Plant Registrations, Volume 19, Issue 1, January/April 2025.
Abstract The sorghum [Sorghum bicolor (L.) Moench ssp. bicolor] germplasm lines Tx3499–Tx3503 (Reg. no. GP‐948–Reg. no. GP‐952, PI 706257–PI 706261) were developed by the Texas A&M AgriLife Research sorghum breeding program in 2024. These lines are resistant to acetyl‐coenzyme A carboxylase (ACCase)‐inhibiting herbicides used for post‐emergence control

RGB‐based indices for estimating cover crop biomass, nitrogen content, and carbon:nitrogen ratio

Agronomy Journal, Volume 116, Issue 6, Page 3070-3080, November/December 2024.
Abstract Plant cover and biochemical composition are essential parameters for evaluating cover crop management. Destructive sampling or estimates with aerial imagery require substantial labor, time, expertise, or instrumentation cost. Using low‐cost consumer and mobile phone cameras to estimate plant canopy coverage and biochemical composition could ...
