Etiolation and PGRs on bentgrass
February 7, 2016
In their recently published paper, "Plant growth regulator effects on bacterial etiolation of creeping bentgrass putting green turf caused by Acidovorax avenae", researcher Joseph Roberts and colleagues studied the interaction of Primo (trinexepac ethyl), Trimmit (paclobutrazole) and Cutless (flurprimidol) with the bacterial decline disease of bentgrass caused by the bacterium, Acidovorax.
The researchers found the following:
- Contrary to popular belief, Primo (trinexepac ethyl) does not cause the elongated, or etiolated foliage associated with bacterial decline. Instead, it is the…
