This book was released on 1971 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reed canarygrass (Phalaris arundinacea L.) is a desirable pasture grass on wet areas in the Northern United States and Southern Canada, but it is a serious and troublesome ditchbank weed in the Pacific Northwest and Rocky Mountain States. The purpose of this study was to learn more about the development, growth habits, and control of reed canarygrass on irrigation ditchbanks. Ninety-seven percent or more of the seed of this species germinated ediately after harvest under favorable conditions. Seeds stored in damp sand at constant temperatures of 1 and 23C for periods of time up to one year did not germinate until they were subjected to alternating temperatures of 20 and 30C. The first rhizome development on reed canarygrass seedlings grown in the greenhouse was observed 26 days after emergence. Within 16 weeks after emergence, the plants were in bloom and had 48 short rhizomes (6.5 cm maximum) per plant. In the field, 88 percent or more of the emergent: shoots on established plants originated from rhizome or tiller buds located in the upper 5 cm of soil. Some shoots developed from buds located at depths up to 20 cm, but none arose from a greater depth. Several vegetative characteristics of reed canarygrass plants collected from six irrigation projects in four states differed widely when grown in a garden at Prosser, Washington. The plant height, seed weights, panicle length, leaf length, leaf width, number of stems per plant, stem diameter, and the rate of spread by rhizomes were statistically different at the 5% level of probability. Large differences in the color and posture of the leaves were also observed. Plants collected near Huntley, Montana, were the most vigorous. Total available carbohydrates in the roots and rhizomes of established reed canarygrass were not affected by single applications of 2,2,dichloropropionic acid (dalapon) at 22 kg/ha, 3-amino-s-triazoleammonium thiocyanate (amitrole-T) at 4.5 kg/ha, or 1,1i-dimethy1-4,4'- bipyridinium ion (paraquat) at 1.1 kg/ha until 2 months after treatments were applied in May. By October, single applications of dalapon and amitrole-T and five repeated applications of paraquat reduced the carbohydrates 24, 28, and 50 percent, respectively. Two additional treatments of dalapon or amitrole-T or five additional treatments of paraquat in the second year of the study did not reduce the carbohydrate levels below those present during the first year. Dalapon and trichloroacetic acid (TCA), applied to the soil or to the senescent foliage in November at rates from 22 to 88 kg/ha, provided good to excellent temporary control of reed canarygrass without denuding ditchbanks. Redtop (Avostis alba L.) and reed canarygrass seedlings developed on the treated areas the following summer and reed canarygrass retained the dominant position unless the seedlings and plants that escaped the fall treatment were controlled with post-emergence applications of dalapon or amitrole-T. When the latter plants were controlled, redtop developed from natural or artificial seeding of the ditchbank and became the dominant species. Maximum residue levels of TCA in irrigation water ranged from 104 to 225 ppb following fall applications of TCA at 82 kg/ha to both banks of three irrigation laterals that ranged from 4 to 14.5 kilometers long. Average residue levels at the downstream ends of the laterals during the first four hours that water flowed through them in the spring ranged from 34 to 47 ppb. Eight hours after the initial flow of water through laterals 4, 8.4, and 14.5 kilometers long, residue levels were less than 1 ppb in the two shortest laterals and only 2.7 ppb in the longest lateral. No residues were detectable in the water from any of the laterals after 48 hours.

Book excerpt: Reed canarygrass (Phalaris arundinacea) is an invasive grass common in wetlands and riparian areas throughout the Pacific Northwest. It is highly adaptable and resistant to many control methods, but is vulnerable to shading. We sought to control reed canarygrass by establishing desirable native shrubs to overtop and shade it. Plots were rototilled, mulched, live-staked, and monitored for 2-6 growing seasons. We tested 1) effective planting densities by live-staking hardhack (Spiraea douglasii) at 50, 30, and 15 cm spacing, 2) relative species performance by planting hardhack, red-osier dogwood (Cornus sericea), and thimbleberry (Rubus parviflorus), all at 30 cm densities, and 3) alternative site preparation methods by using cardboard mulch or excavating the top 20 cm of topsoil. Higher planting density significantly reduced reed canarygrass cover and biomass. Both hardhack and red-osier dogwood successfully suppressed reed canarygrass, though thimbleberry did not. No significant differences between site preparation methods were observed.

This book was released on 2011 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phalaris arundinacea (reed canarygrass) is a grass species native to Eurasia and the Pacific Northwest of the U.S. By nature it is an aggressive species and particularly invasive in areas with abundant light and nutrient resources. Repeated introduction of cultivars to the U.S. for purposes of feedstock and soil stabilization particularly around farmlands from the 1850s onward allowed cross-pollination with native cultivars to occur. This resulted in more aggressive phenotypes capable of forming monotypic stands. The susceptibility of wetland areas to invasion has become particularly problematic in the Pacific Northwest and the Midwest. One widely recognized method of control for reed canarygrass growth and establishment is the use of shade. This study proposed the use of artificial shade in combination with the planting of native grass species in an attempt to diversify a wet meadow dominated by reed canarygrass. Three-way ANOVAs were utilized to analyze shade, disturbance patch size, and mowing as treatment levels. Results showed reed canarygrass to be noticeably impacted by shading while one native grass species successfully established itself under the same conditions. Given a sufficient length of time, diversity of this area could potentially be increased both aboveground and in the seed bank.

This book was released on 2002 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The West Eugene Wetlands, Eugene, Oregon, which provide habitat for number of endemic and endangered plant species, are currently threatened by a Reed canarygrass (Phalaris arundinacea L.) invasion. This study addresses the hypothesis that Phalaris spread can be explained in part by using watershed-scale landuse patterns as surrogates of the water quality and hydrologic regime in the associated watersheds. A multiple regression model was constructed to test the effects of watershed-scale landuses on Phalaris abundance. The spatially referenced landuse attributes were estimated using accumulated inverse-squared flow path distances between each wetland and cells in a grid-based representation of landuse/cover data in a Geographic Information System. The locally measured physical and biological characteristics of wetlands were also incorporated into the model to adjust for site differences. Bias in the estimated parametric coefficients were found to be negligible using 1,000 iterations of a bootstrap re-sampling technique. Bias-corrected-and-accelerated intervals also supported the significance of these estimates. The inferential model, consisting of the percentage open water cover in the wetlands, an indicator of highly disturbed site and watershed-scale urban and forest landuses, explained 67 percent variation of Phalaris abundance. There was convincing evidence that the cumulative watershed-scale landuse patterns affected Phalaris abundance (p-value
