Alteration of traditional and non-traditional plant growth regulators (pGR) treatments on the growth characteristics of Mentha piperita Linn. (pippermint, Family: Lamiaceae) was investigated in the present study. The traditional PGR used were gibberellic acid (GA3), Abscisic acid (ABA) and non-traditional POR used were Difenoconazole (DIZ) by soil drenching on 35, 50, 65 and 80 days after planting (DAP). The plants were taken randomly on 45,60, 75 and 90 DAP and used for estimating the growth and biochemical changes. DIZ and ABA treatments increased the fresh weight, dry weight, root growth, total chlorophyll and carotenoid content, while it decreased the stem length. Among the treatments GA₃ enhanced the fresh and dry weights and stem length increased the larger extent. Photosynthetic pigments were increased in DIZ treatments when compared to control.
