A 2-yr study was conducted to document the influence of selected buffalograss, Buchloë dactyloides (Nuttall) Engelmann, management practices (three mowing heights and five nitrogen levels) on the seasonal abundance of the western chinch bug, Blissus occiduus Barber (Heteroptera: Lygaeidae), and its beneficial arthropods. Vacuum, pitfall, and sticky traps samples were collected every 14 d from t...

nowadays, establishment and maintenance of turfgrasses due to high water requirements was faced with serious doubts. hence, screening of drought resistance native grasses, and introduces them as turfgrass is not only effective in reduction of water usage but can also preserve plant gene pools of the country. in the present experiment, wheat grass and bromus as two native grasses were compared w...

Anthracnose (Colletotrichum cereale Manns sensu lato Crouch, Clarke & Hillman) has been a devastating disease on annual bluegrass (ABG) [Poa annua L. f. reptans (Hausskn.) T. Koyama] putting green turf over the past 15 yr. The objectives of this 2-yr fi eld trial on ABG were to evaluate the impact of mowing height (2.8, 3.2, and 3.6 mm), mowing frequency (seven and 14 times wk–1), lightweight r...

It is unclear how N addition and mowing interactively affect grassland community structure function. We studied the short-term effects of on species diversity biomass a typical in Inner Mongolia using split-plot design, with whole plot representing treatment subplot rate. Three stubble heights were set at 10 cm (M2), 6 (M3) 3 (M4), no-mowing (M1) was also included. consisted five rates, i.e., 0...

2 Corresponding author: [email protected] 3 Current address: Department of Biological Sciences, Binghamton University, Binghamton, NY 13902 ABSTRACT: We investigated the effects of mowing on butterfly counts in fields and woodland openings in upstate New York. We predicted that total counts of butterfly individuals would decrease immediately after mowing, but increase in the year following m...

To improve the efficiency of chromium (Cr) phytoextraction by Leersia hexandra Swartz, effects mowing on Cr accumulation in L. were investigated using hydroponic experiments. Mowing heights (0, 5, and 10 cm), interval (30, 60, 90 120 days), frequencies (1, 2, 3 times) optimized. at cm above roots significantly increased shoot biomass (32.9 g/pot). The days achieved highest (62.8 with thrice (67...

John C. Inguagiato, Ph.D. James A. Murphy, Ph.D. Bruce B. Clarke, Ph.D. Anthracnose, caused by the fungus Colletotrichum cereale (2), has become a common disease of annual bluegrass (Poa annua) and, to a lesser extent, creeping bentgrass (Agrostis stolonifera) greens throughout the world (9). The disease may occur as a basal rot of necrotic, watersoaked crown tissue at any time of the year or a...
