Distinct Compared to Other Post Herbicides for Corn
by Donald E. Null, Regional Agronomy Specialist
University Outreach and Extension, NW Region
Objective: To determine the efficacy and crop response of
Distinct and compare it to other post weed control products for
corn.
Methods: Burrus BX86 corn was planted on May 18 into a
conventionally tilled area of the farm. A pre-emergence
application of Dual II, at the rate of 1.4 pints/acre was
broadcast across all treatments. Corn, 10-18" tall, was treated
on June 24. Weeds present were 6-12" cocklebur (moderate to
heavy pressure), and light to moderate pressures of 2-4"
velvetleaf, 2-6" morningglory, 6-12" sunflower,2-6" waterhemp and
6-12" shattercane.
Results: The bulk Dual II treatment across all plots
provided near complete control of giant foxtail and common
waterhemp in the study. Crop damage was minimal, however, there
was some leaf whorl chlorosis following the Hornet and Spirit
applications. The corn rapidly grew out of this crop response.
Ratings were taken on July 15. The results are in the table
below. All treatments include a non-ionic surfactant at 0.25%
v/v and 28% nitrogen solution at 1.25% v/v.
An interesting note on the Distinct treated shattercane
(ShtCn) is that at rating time the shattercane in these plots was
lying flat on the ground. The plants were still alive but they
were damaged severely.
