“…Navneet Kaur 1,*,and Eileen A. Buss 2 Use of plant growth regulators is a common practice by turfgrass managers to regulate grass canopy heights and reduce mowing frequency (Watschke et al 1992). Plant susceptibility to insect herbivory can be manipulated by using plant growth regulators to change a plant's physical or biochemical properties (Singer & Smith 1976;Coffelt & Schultz 1988;Campbell 1998;Turgeon 1999).…”

“…Suppression of flower initiation in sugarcane (Saccharum officinarum) (Meyer et al, 2013) seems to be the only current use of DQ as a growth regulator. FS belongs to the sulfonylurea herbicides, some of which are listed as growth regulators (Watschke et al, 1992). McCullough et al (2011) tested FS for the plant growth regulation of seashore paspalum (Paspalum vaginatum), achieving up to 75% clipping reduction and up to 86% seed head suppression compared with the untreated control.…”

Vegetatively propagated warm-season turfgrasses are established with methods that rely on large quantities of propagation material and subsequent plant growth support. The precision seeding adopted for some seed propagated crops controls the depth and spacing at which seeds are placed in the soil. Sprigs that are reduced in length could potentially be suitable for existing machinery, and precision planting could enhance the efficiency of use of the propagation material. The aim of the present study was to carry out a preliminary screening on products known to act as plant growth regulators to explore their potential use for controlling stolon development and elongation of ‘Patriot’ hybrid bermudagrass (Cynodon dactylon × C. transvaalensis) grown in pots for propagation purposes. Trinexapac-ethyl (TE), chlormequat chloride (CM), paclobutrazol (PB), propiconazole (PPC), diquat (DQ), flazasulfuron (FS), glyphosate (GP), ethephon (EP), and gibberellic acid (GA) were applied to pot-grown ‘Patriot’ hybrid bermudagrass turf in eight different application rates, ranging for each product from the minimum expected effective rate to a potentially harmful rate. Of the tested treatments, TE applied at 2.0 kg·ha−1 and PB applied at 1.0 kg·ha−1 reduced stolon and internode length without causing a reduction in the stolon number or turf quality. PPC was also effective in reducing stolon length, but the effect on internode length was not statistically significant. Stolon length was unaffected by CM, while DQ and GP induced stolon elongation. FS, EP, and GA affected stolon length without a consistent relation between stolon length and application rate. The chemical suppression of stolon elongation in pot-grown ‘Patriot’ hybrid bermudagrass can contribute to controlling sprig size for use with precision seeding machinery.

“…Reducing turfgrass leaf growth with plant growth regulators (PGRs) has become a common practice in intensive turfgrass management and may provide smoother putting surfaces by promoting lateral growth instead of undesirable top growth (5,15). Using PGRs to reduce daily growth fluctuations may provide more consistent putting surfaces and may be a less stressful way to produce high-quality putting greens over the growing season.…”

This study was conducted on an annual bluegrass (Poa annua L.) putting green and examined the effects on ball roll distance (BRD) from five mowing and rolling frequency regimes using both a light and heavy roller with and without Primo Maxx. Treatments included: (i) mow daily with no rolling; (ii) mow daily + roll M, W, F; (iii) mow daily + roll daily; (iv) mow M, W, F, Sa + roll daily; and (v) alternate mowing and rolling daily. For six weeks during the summers of 2009 and 2010, ball roll distances were measured in the morning and afternoon, Monday through Friday. BRD decreased an average of 0.5 ft from the morning to the afternoon. The heavy roller significantly increased BRD in 2009 by 0.4 ft or less, but not in 2010. Primo Maxx increased BRD an average of 0.5 ft in 2010, but not in 2009. Mowing + rolling daily produced the longest BRD followed by mow daily + roll M, W, F and mow M, W, F, Sa + roll every day which was 0.5 ft less. Mow daily with no rolling and alternate mowing and rolling daily had the shortest BRD averaging 1.2 ft less than mowing and rolling daily.
