Evaluation of tall fescue-zoysiagrass polystands and new zoysiagrass genotypes for use in the transition zone
Zoysiagrasses (Zoysia spp.) use C4 metabolism and are more drought resistant than C3 grasses. However, the long dormancy period between autumn and spring limits the use of zoysiagrass by homeowners and professional turfgrass managers. In addition, large patch has become the primary pest on …

Factors governing zoysiagrass response to herbicides applied during spring green-up
Zoysiagrass (Zoysia spp.) is utilized as a warm-season turfgrass because of its density, visual quality, stress tolerance, and reduced input requirements. Turf managers often exploit winter dormancy in warm-season turfgrass to apply nonselective herbicides such as glyphosate and glufosinate to …

Integrating nitrogen source and application timing into the management of large patch on zoysiagrass
… patch is the most limiting disease that affects zoysiagrass in the upper transition zone of the United States. Management of this disease requires two to four fungicide applications split between the fall and spring disease periods. Limited research has been conducted to determine the effects of …

Managing Stress Tolerance on Warm-Season Putting Greens in the Transition Zone
… zone, however, newly developed greens-type zoysiagrass (Zoysia spp.) cultivars represent another potential selection for golf courses. The two major limitations of warm-season grasses in the transition zone are a general lack of cold- and shade-tolerance. Protective covers are essential to …

Response of selected warm-season turfgrasses and ornamental monocots to short-term, high concentration, ozone fumigation
… centipedegrass (Eremochloa ophiuroides), zoysiagrass (Zoysia japonica), St. Augustinegrass (Stenotaphrum secundatum), Liriope muscari ‘Big Blue’, Liriope muscari ‘Aztec’, and Ophiopogon japonicus. Zoysiagrass, St. Augustinegrass, Liriope muscari ‘Big Blue’ were used in the second study …

EFFECT OF TEMPERATURE, AERATION, NUTRITION AND GENOTYPIC DIFFERENTIALS ON RESPONSES OF ZOYSIA SPECIES TO IRON STRESS
Eleven zoysiagrass genotypes with known reactions to Fe-stress were grown under either growth chamber or greenhouse conditions in a series of four separate experiments. Genotypes grown in the growth chamber studies were subjected to three temperature ranges (18-12(DEGREES)C, 30-21(DEGREES)C, a
