Evaluation of Pentia™ as a Cotton Plant Growth Regulator on DP 555 BG/RR

John C. Coccaro, H. William McCarty, Alvin Rhodes, and H.R. Smith

ABSTRACT

The objective of this experiment was to compare the effects of Mepiquat Chloride (MC), Pix Plus (MC and the bacteria Bacillus cereus), and Pentia (mepiquat pentaborate) on a specific cotton (Gossypium hirsutum L.) variety - Delta and Pine Land 555 BG/RR (DP 555 BG/RR )- for growth, earliness and yield. Compared with the untreated control, each of the plant growth regulators reduced plant height. Pentia and Pix Plus reached 60% open boll stage earlier and had numerically higher yields compared to the MC treatment or the untreated control.
