Summary of Apogee/Kudos Research at NC State University

David Jordan, NC State University

Research has been conducted since 1994

Almost always improves row visibility

Main stem height is almost always shorter

Not mobile in the plant, so good coverage is essential

Compatible with most pesticides and micronutrients

Nitrogen as an adjuvant is essential

Performance by Apogee and Kudos the same

With older varieties tended to see more increases in yield with Apogee

Holds the more mature pods on longer

Does not hasten maturity

Very few instances of yield increases in small plots with Bailey

More recent research focus on rates and number of applications

Less expensive now than when initially marketed

Current price makes Apogee or Kudos attractive

Approximately 50% of growers in the North Carolina and Virginia making at least one application
