“…ha −1 reduced root mass and reduced magnesium and manganese content in hybrid bermudagrass foliage compared with the nontreated check; however, investigators evaluated higher indaziflam rates in systems that contained less organic matter compared with the presented research. These data agree with previous research indicating that oxadiazon does not adversely affect hybrid bermudagrass rooting (Fishel and Coats, 1993; Beck et al, 2013).…”

Preemergence herbicides are used for weed control in turfgrass systems. Indaziflam is a preemergence herbicide used in warm‐season turfgrasses for grassy and broadleaf species. Field research was completed to evaluate the effect of various preemergence herbicide application regimens on established hybrid bermudagrass [Cynodon dactylon (L.) Pers. × Cynodon transvaalensis Burtt‐Davy ‘Tifway’] cover and root mass on sand soils. Evaluated regimens included indaziflam followed by (fb) indaziflam (14 g a.i. ha−1 fb 14 g a.i. ha−1), indaziflam fb indaziflam (21 g a.i. ha−1 fb 21 g a.i. ha−1), indaziflam fb oxadiazon (21 g a.i. ha−1 fb 3285 g a.i. ha−1), indaziflam fb prodiamine (21 g a.i. ha−1 fb 821 g a.i. ha−1), prodiamine fb oxadiazon (821 g a.i. ha−1 fb 3285 g a.i. ha−1) and prodiamine fb prodiamine (821 g a.i. ha−1 fb 821 g a.i. ha−1) applied fall fb late winter in each of two yr. Indaziflam treatment regimens did not adversely affect hybrid bermudagrass cover compared with the nontreated check at any evaluation time. Indaziflam fb prodiamine was the only treatment that consistently reduced hybrid bermudagrass root mass compared with the nontreated check. Results of this research indicates low rates (≤21 g ha−1) of indaziflam may be used without adversely affecting hybrid bermudagrass cover or rooting, providing practitioners with an alternative mode of action compared with conventional mitotic and protoporphyrinogen oxidase inhibitors; however, additional research is needed to quantify effects over multiple application seasons and years.

Methiozolin is commonly used for the safe and selective removal of annual bluegrass from creeping bentgrass golf greens. Studies were conducted in 2013 and 2014 with the objective of assessing fertility programs consisting of synthetic fertilizers and biostimulants, with and without the plant growth regulator trinexapac-ethyl, to aid putting green canopy recovery following annual bluegrass removal via methiozolin. Additional studies were conducted to compare recovery of creeping bentgrass following an aggressive core aerification event with fertility programs with and without methiozolin. In all cases, the addition of 7 kg ha-1 of N, P, and K from fertilizer or biostimulant biweekly to greens increased turfgrass recovery time by 1 to 3 wk compared to a standard green’s fertility program alone. Creeping bentgrass treated with biostimulants recovered equivalent to or quicker than creeping bentgrass treated with synthetic fertilizer (SF) in all cases. In the presence of methiozolin treatments, trinexapac-ethyl reduced time to 90% recovery (T90) by 0.25 to 0.5 wk at two locations and increased T90 recovery time by 0.1 wk at one location. Otherwise, SF plus trinexapac-ethyl treated plots were equivalent to SF-only plots. Methiozolin slowed turfgrass recovery time at one location where severe drought stress occurred but not at the other location that did not experience drought stress. These results suggest that turf managers should increase fertilizer treatments but will not need to discontinue trinexapac-ethyl use to maximize creeping bentgrass recovery following annual bluegrass control with methiozolin. These data also suggest that methiozolin has the potential to negatively affect creeping bentgrass recovery when drought stress is experienced.

“…Based on a review of the literature, there have been no studies of how cultivation practices such as vertical mowing and solid-tine aerification affect bermudagrass recovery from SDS within the same growing season. Moreover, SDS patches can be slow to recover because of the use of certain preemergence herbicides or metabolites produced by the pathogen that can inhibit shoot regrowth (Beck et al, 2013;Fermanian et al, 1981;Venkatasubbaiah et al, 1994). Therefore, methods to aid in bermudagrass recovery from SDS damage are needed.…”

Spring dead spot (SDS), caused by Ophiosphaerella spp., is among the most damaging diseases to hybrid bermudagrass (Cynodon dactylon × transvaalensis) in areas where winter dormancy occurs. Management strategies that aid in turfgrass recovery from SDS damage have not been widely studied. An experiment was conducted in Blacksburg, VA, in 2019 and 2020, to determine the influence of various cultural practices on bermudagrass recovery from SDS damage. Fertility and cultivation were applied in the late spring/early summer, which is earlier than normal for cultivation practices for bermudagrass, to test their effectiveness in aiding bermudagrass recovery from SDS damage. The main effects of fertility and cultivation were arranged in a 2 × 3 factorial design with vertical mowing, solid-tine aerification, and no cultivation applied with urea (48.8 kg⋅ha−1 N) sprayed at trial initiation and 2 weeks later or without urea. Plots were assessed for the percent of SDS throughout the study. Data were analyzed as the percent change relative to the initial assessment to measure bermudagrass recovery. The main effect of fertility increased bermudagrass recovery from SDS damage in both 2019 and 2020. The main effects of vertical mowing and solid-tine aerification reduced bermudagrass recovery from SDS damage in 2020. These data suggest that two properly timed nitrogen fertilization applications at 48.8 kg⋅ha−1 optimized bermudagrass recovery from SDS damage, whereas late spring/early summer cultivation without fertility may inhibit bermudagrass recovery.
