Winter annual weeds become a major problem during winter dormancy in warm-season turfgrass stands. In the transition zone, glyphosate application is common practice to reduce weed competition zoysiagrass before emerging from spring. Research was conducted on effects of timings spring greenup and quality experimental genotypes compared commercially available cultivars. Preliminary data this stud...

In order to determine aqueous extract effects of cool-season turfgrass mixture clipping on germination and seedling growth of four weed species, laboratory and outdoor pot experiments were done at the experimental laboratory and greenhouse of the Doroud Parks and Landscape Organization, located in Doroud, Lorestan, Iran. The first factor was the concentration of sport turfgrass clipping extract...

Integrated pest management (IPM) programs have been developed for almost all agricultural and ornamental crop production systems over the past two decades. But only recently have IPM and organic management systems been considered a truly primary approach in professional turfgrass management. The reasons for the dramatic increase in organic approaches are centered on public concern for the envir...

Weeds are a major pest that reduce aesthetics and functionality of turfgrass systems. Knowledge required for effective weed management has evolved in recent years as weeds develop resistance to herbicides, government restriction broad-spectrum herbicides increased, registration new herbicide active ingredients slowed. This chapter discusses relevant developments synthetic alternatives non-chemi...

Creeping bentgrass ( Agrostis stolonifera ) is a desirable turfgrass putting green species that susceptible to drought stress. Planting drought-resistant creeping will enhance the resilience of golf turf surfaces, lower required resource inputs, and reduce environmental impact courses. cultivar performance data during stress are needed for informed selection appropriate cultivars. We evaluated ...

Pink snow mold (Mirodochium patch) and gray snow mold [Typhula blight) are the most prevalent and destructive winter diseases on cool-season turfgrass in the northern United States. They are especially destructive in the Intermountain Northwest where deep snow cover may last four to five months. Pentachloronitrobenzene (PCNB, Quintozene) has been use to manage these diseases in turf on golf cou...
