An article in the current issue of Weed Technology presents results of field tests to determine the most effective timing of residual herbicides for control of glyphosate-resistant Italian ryegrass. The researchers found that an effective management program for glyphosate-resistant Italian ryegrass starts with the application of herbicide prior to emergence, between mid-October and mid-November. Lawrence, Kansas (PRWEB) May 15, 2014 Italian ryegrass has shown resistance to five different...

A collaboration of plant and soil scientists from across the UK has shown a grass hybrid species could help reduce the impact of flooding. The BBSRC-funded scientists, from Rothamsted Research, the James Hutton Institute, Institute of Biological, Environmental and Rural Sciences (IBERS) at Aberystwyth University, Lancaster University and the University of Nottingham, used a hybridized species of grass called perennial ryegrass (Lolium perenne) with a closely related species called meadow...

University of Oregon biologist finds unwanted plants don't necessarily have it easy in absence of old enemies After hiking in Oregon, a University of Oregon plant biologist suggests, people may want to brush off their shoes and comb through their dogs in an effort to curb the spread of an invasive grass that is expanding its range. The grass is false brome (Brachypodium sylvaticum), a native of Europe and Asia, which likely landed in Oregon by way of USDA experimental plots in 1939 near...

Threat to ecosystem biodiversity studied using multiple interactions Invasive species cost an estimated $1.4 trillion annually in their environmental and economic impacts worldwide and are second only to habitat loss as a threat to biodiversity. As scientists struggle with the challenge of controlling invasive species, the question of why some species are so successful continually arises. Recent research conducted by Dr. Alison Bennett and Dr. Sharon Strauss at the University of California,...

Invasive grasses are better equipped than natives to deal with increasing temperatures California's native grasses, already under pressure from invasive exotic grasses, are likely to be pushed aside even more as the climate warms, according to a new analysis from the University of California, Berkeley. In the study, which has been accepted for publication in the journal Global Change Biology and is now available online, UC Berkeley biologists catalogued the ranges of all 258 native grasses...

Tiny mice advance under of invasive beachgrass to feast on seeds of endangered plant At Point Reyes National Seashore in Marin County, Calif., a fierce battle is taking place under the oblivious, peeling noses of beachgoers. It's a battle between an invasive plant and a native plant, but with a new twist. The two plants, European beachgrass and Tidestrom's lupine, are not in direct competition, and yet the beachgrass is helping to drive the lupine over the cliff. European beachgrass provides...

For more than two decades, Agricultural Research Service (ARS) scientists have been developing new grasses and forages that can hold their own on the rugged rangelands of the western United States. As a result of that work, the scientists have released many improved plant varieties that help restore vegetation communities struggling for survival in the face of extreme weather conditions, wildfires, soil erosion, invasive plant species and other challenges. Research leader Jack Staub and other...

As the U.S. Department of Energy (DOE) works toward developing sustainable sources of clean renewable energy, perennial grasses have emerged as major candidates for the commercial production of cellulosic biofuels from feedstocks. However, little is known about the specific biological traits of the grasses that might contribute to their usefulness for energy production, in part because such grasses typically have long lifecycles and possess large, complex genomes, making them difficult to...

AVALON, Calif. (AP) - A species of grass not seen since 1912 has been discovered growing on Santa Catalina Island off the Southern California coast, botanists say. The plant, California dissanthelium, had long been thought extinct until a botanist recently spotted the wispy, 7-inch-tall tufts while hiking in Cottonwood Canyon. "I saw a little grass, and I thought, 'Hmm, that doesn't look familiar,'" said Jenny McCune, an assistant plant ecologist for the Catalina Island Conservancy. McCune...
