“…Effective bermudagrass control is best achieved with multiple (2-4) applications of glyphosate + a graminicide, typically on a 3-to 4-wk interval, with re-applications timed to coincide with bermudagrass recovery from initial treatment (Boyd, 2000;Teuton et al, 2005). As such, bermudagrass eradication is a long-term process that can take a minimum of 6 to 8 wk to complete.…”

Herbicide control options for bermudagrass [Cynodon dactylon (L.) Pers or C. dactylon x C. transvaalensis Burtt-Davy] include non-selective herbicides such as glyphosate (N-[phosphonomethyl] glycine), as well as selective graminicides such as fenoxaprop (Fenoxaprop-P-ethy) and fluazifop (Fluazifop-P-butyl).Regardless of the herbicide used, effective bermudagrass control can only be achieved with repeated applications. Fraise mowing has been recently introduced into the turfgrass industry and these machines can remove thatch and growing points down to a depth of 5.0 cm. Our hypothesis was that if a high percentage of the growing points of a bermudagrass stand were physically removed with fraise mowing, the remaining growing points would be more easily controlled with various herbicides. Six trials were conducted over two seasons to determine if fraise mowing and herbicides could be used in combination to improve bermudagrass control. Treatments included various combinations and timings of glyphosate (2.74 kg a.i. ha −1 ) and fluazifop (0.42 kg a.i. ha −1 ), applied to plots that were fraise mowed to a depth of 3.75 cm or not fraise mowed.Fraise mowing alone physically removed a significant amount of the bermudagrass growing points and provided partial bermudagrass control. A combination of fraise mowing and herbicide generally improved bermudagrass control over the herbicides alone. Herbicides applied after fraise mowing generally provided better bermudagrass control in comparison to applying herbicides prior to fraise mowing. Aggressive fraise mowing appears to be a tool that can improve bermudagrass control and could shorten the overall time window needed to remove existing bermudagrass from a site. INTRODUCTIONBermudagrasses [Cynodon dactylon (L.) Pers or C. dactylon x C. transvaalensis Burtt-Davy] are some of the most widely grown turfgrass species in tropical and sub-tropical Abbreviations: DAT, days after last herbicide treatment.

Tropical signalgrass (TSG) has become a serious weed problem in tropical and subtropical regions such as Florida in recent years in association with the ban of organic arsenical herbicide use in turf. The purpose of this research was to identify alternative POST herbicides that control TSG. Two field experiments were conducted in bermudagrass golf course fairways in south and central Florida in 2014 and 2015. Several nonorganic arsenical herbicide treatments controlled TSG. In the first experiment, treatments containing amicarbazone alone and in combination with other herbicides provided > 97% TSG control 12 wk after initial treatment (WAIT) in 2014 and 2015. These included a single application of amicarbazone at 0.49 kg ai ha−1, or sequential applications of amicarbazone at 0.25 kg ha−1in combination with foramsulfuron at 0.04 kg ai ha−1, sulfentrazone + imazethapyr at 0.25 kg ai ha−1, thiencarbazone + foramsulfuron + halosulfuron at 0.14 kg ai ha−1, and thiencarbazone + iodosulfuron + dicamba at 0.18 kg ai/ae ha−1. In the second experiment, sequential applications of thiencarbazone + foramsulfuron + halosulfuron at 0.14 kg ha−1in combination with either quinclorac at 0.84 kg ai ha−1or metribuzin at 0.28 kg ai ha−1provided ≥ 85% TSG control 12 WAIT in both years.
