CONTROL OF BLACK CUTWORM WITH TRANGENTIC HYBRID, 2012

The purpose of this experiment was to examine the control of Black cutworm Agrotis ipsilon (Hufnagel) with transgenic technology. The experiment was conducted during 2012 at the Haskell Agricultural Laboratory in Concord, Nebraska. Experimental design was a RCB with six replications. The plots were 30 inch row wide by 10 ft in length. Each plot had a metal barrier placed around the boarded of the plot. On 26 May this trial was hand planted into tilled soybean residue. Artificial Infestation occurred 7 Jun; two larvae were placed by each plant in every plot. Assessments were made at 7, 14, and 21 days after infestation and the number of plants damaged, the number of plants cut above ground and the number of plants cut below ground was recorded. Results were converted to a percentage of total plants in each plot and then analyzed using ANOVA procedures. Treatment means were separated using LSD procedures.
