Agronomy and Horticulture Spring 2023 Seminars Announced
The spring Agronomy and Horticulture seminar series begins with “Soybean Response to Micro-rates of Dicamba and 2, 4-D” presented by Nebraska’s Stevan Knezevic on Friday, Feb. 3.
Stevan Z. Knezevic, professor of agronomy and horticulture, will present on the off-target movement of dicamba and 2,4-D, a concern with the introduction of dicamba-tolerant (DT) and 2,4-D-tolerant (Enlist) soybeans in North America and elsewhere. Therefore, field studies were being conducted in Nebraska to evaluate glyphosate-tolerant (GT) soybean response to micro-rates (0, 1/1000th, 1/500th, 1/100th, 1/50th, 1/10th) of the label rates of dicamba and 2,4-D applied at V2, V7/R1 and R2 soybean growth stages. Both herbicides negatively influenced multiple growth parameters of GT soybeans including visual injury, plant height, physiological maturity as well as yield and yield components. In all cases, injuries and yield reductions from dicamba were significantly higher than those from 2,4-D for the same rate.
All seminars are free and open to the public. Seminars will be in person, streamed live via Zoom and recorded at 3:30 p.m. in Keim Hall, Room 150, unless otherwise noted.
Recordings of past seminars are also available in the Agronomy and Horticulture archives.
