Aerial seeding of Italian annual ryegrass (Lolium multiflorum) is a common, but controversial, emergency rehabilitation practice following wildfire in California. Replicated study plots, with and without ryegrass, established after a summertime chaparral wildfire on California's central coast revealed the following: 1. Ryegrass-seeded plots developed significantly greater total plant cover than...

Type 1 allergic reactions, such as hay fever and allergic asthma, triggered by grass pollen allergens are a global health problem that affects approximately 20% of the population in cool, temperate climates. Ryegrass is the dominant source of allergens because of its prodigious production of airborne pollen. Lol p 5 is the major allergenic protein of ryegrass pollen, judging from the fact that ...

Flazasulfuron is a selective herbicide registered for use in warm-season turfgrass. Concerns have been raised over its mobility surface water runoff. Studies were conducted Blacksburg, VA and Charlottesville, to evaluate injury Lolium perenne L. (perennial ryegrass) downslope of plots treated with transition-assisting herbicides, including flazasulfuron, pronamide, trifloxysulfuron sodium. (52 ...

Lolium perenne L. (perennial ryegrass) commonly contaminates Agrostis stolonifera (creeping bentgrass) on cool-season golf courses. Currently, few herbicide options are available for the selective control of in A. stolonifera. Previous studies have indicated that flazasulfuron could be a potential solution, so trials were conducted at three sites Blacksburg, VA to evaluate rates and sequential ...

In New Zealand, agriculture is predominantly based on pastoral grazing systems and animal excreta deposited on soil during grazing have been identified as a major source of nitrous oxide (N2O) emissions. Forage brassicas (Brassica spp.) have been increasingly used to improve lamb performance. Compared with conventional forage perennial ryegrass (Lolium perenne L.), a common forage in New Zealan...

allelopathy is one of the valuable tools in weed management that recently is considered in sustainable agriculture and reduces herbicide rate challenges. in order to study the allelopathic effects of rye (secale cereal l.) on six weed spices seeds including milk thistle (silybum marianum l.) gaertn, wimmer ryegrass (lolium rigidum gaudin), lesser canarygrass (phalaris minor retz.), charlock mus...

Increasing the total lipid concentration and modifying the fatty acid profile in forage may increase energy intake and productivity of animals and improve the attributes of meat and milk for human health. To predict the outcome of modifying these traits in ryegrass, 3 groups of weaned lambs (n=15 per treatment) grazed ryegrass (4% total lipid) and received twice-daily oral doses of oil at 0, 28...

Perennial ryegrass (Lolium perenne L.) is widely used for forage production in both permanent and temporary grassland systems. To increase yields in perennial ryegrass, recent breeding efforts have been focused on strategies to more efficiently exploit heterosis by hybrid breeding. Cytoplasmic male sterility (CMS) is a widely applied mechanism to control pollination for commercial hybrid seed p...

Ground covers were tested for 3 consecutive yr for their effect on Japanese beetle, Popillia japonica Newman (Coleoptera: Scarabaeidae), abundance and behavior in a blueberry planting. Alsike clover (Trifolium hybridum L.), buckwheat (Fagopyrum esculentum Moench), perennial ryegrass (Lolium perenne L.), and bare ground were compared within row-middles for their effect on abundance of adult fema...
