Bermudagrass (Cynodon dactylon (L.) Pers.) interference reduced yield of ‘Valencia’ oranges (Citrus sinensis (L.) Osbeck) more than annual weeds. Both types of vegetation also resulted in decreased leaf nitrogen, increased juice content, soluble solids, and titratable acid. Bermudagrass competition resulted in increased fruit size. Complete or partial weed control eliminated or reduced adverse effects of competitive vegetation on fruit production.

With the emergence of glyphosate-tolerant cultivars, identifying management strategies not applicable with older cultivars need to be revisited. Objectives of these research trials were to quantify the growth regulation effects following a glyphosate application and to determine the safety of tank mixing glyphosate with another herbicide, various nitrogen (N) sources, and a plant growth regulator (PGR) on a glyphosate-tolerant perennial ryegrass [PRG (Lolium perenne L.)] cultivar, Replay. In the growth regulation trial, glyphosate was applied at 0 to 1.03 lb/acre, whereas PGRs flurpimidol, trinexapac-ethyl, paclobutrazol, and trinexapac-ethyl + flurpimidol were applied at 0.50, 0.18, 0.37, and 0.09 + 0.22 lb/acre, respectively, on 15 July 2010 and 2 Aug. 2012. In the tank mixing trial, dicamba (0.50 lb/acre), urea (15 lb/acre N), and ammonium sulfate [AMS (15 lb/acre N)] were applied alone or tank mixed with glyphosate at 0 to 0.52 lb/acre. Tank mixing urea with glyphosate had minimal effect on PRG color, while adding AMS consistently improved color at the highest glyphosate rate of 0.52 lb/acre. Twenty days following a glyphosate application, only rates >0.40 lb/acre resulted in significant growth regulation compared with untreated plots. This study indicates that tank mixing glyphosate with another herbicide, a PGR, and various N sources appear safe to the glyphosate-tolerant PRG cultivar. Also, the growth regulating effects of glyphosate applications would serve as an additional benefit to annual bluegrass (Poa annua L.) control reported in previous trials.
Injury to turfgrass leaf segments was measured as percent electrolyte leakage as affected by the duration and level of imposed heat stress. Species differences in heat tolerance were most apparent when injury was monitored over time at 50°C, using leaf segments which were obtained from heat-hardened plants and immersed in distilled water during the stress treatment. Quantitative differences in heat tolerance in vitro were consistent with qualitative descriptions of drought resistance for most of the species tested.
Winter overseeding of dormant bermudagrass ( Cynodon dactylon sp.) athletic turf has been a common practice in the transition zone and southern United States. Winter overseeding provides an actively growing cool-season turfgrass stand that provides
This experiment was conducted to determine effects of herbicides on the control of noxious perennial grass weeds. The results indicate that the rate, timing, duration and number of applications employed were the major factors in the successful control of perennial grass weeds such as Cogon Grass (Imperala cylindrica), Johnson Grass (Sorghum halepense), Bermuda Grass (Cynodon dactylon), Nut Grass (Cyperus rotundus) and Common Red (Phragmites spp.), commonly found in Iraq growing both in cultivated fields and wild on uncultivated land.
