Effects of Early-Season Cobra Herbicide (lactofen) Treatment On Agronomic Development and Yield of Soybean.

ABSTRACT

Soybean, Glycine max, are one of the most important crops in Tennessee, and ways to increase yield are continually being evaluated. Postemergent application of the herbicide lactofen during early vegetative growth stages can damage the terminal of the plant causing increased branching and therefore increased branch pod numbers. A field study was conducted in Union City, TN, in 2012 to evaluate the application of lactofen at different rates with varied surfactants to determine the change in the soybean morphology and increased soybean yield on multiple Pioneer soybean cultivars.
