SELECTION EVALUATION OF THE SOURCE MATERIAL OF FESTUCA RUBRA L. OF THE LAWN DIRECTION

The aim of the research was to assess the breeding value of the source material of F. rubra of the lawn direction obtained under conditions of various ecotopes of the south of the Central Russian Upland with a predominance of carbonate substrate. In total, 106 numbers of red fescue of various genetic and geological-geographical origin were evaluated in the experiment: 4 varieties and 102 breeding samples. Tests of the breeding value of the collection numbers were carried out in comparison with the zoned varieties of domestic selection (‘Veselka’, ‘Gostenka’, ‘Iskrinka’) and foreign selection (‘Gondolin’). The forms of F. rubra have been identified, approaching erect in shape, having a high shoot-forming ability, pronounced antocian color of inflorescences, whitish bloom on the leaves, which increases the overall decorative effect of lawn herbage. According to a number of important traits for breeding for seed productivity, the forms selected in natural habitats with a predominance of carbonate substrate have wide limits of variation and can serve as genetic sources of individual breeding traits for obtaining new varieties of lawn management with high seed productivity and decorativeness.

A Review of Organic Lawn Care Practices and Policies in North America and the Implications of Lawn Plant Diversity and Insect Pest Management

There are ≈40 million acres of turfgrass lawns throughout the United States, most of which are managed under chemical-intensive pest and fertilizer programs. “Organic lawn care” is being adopted more widely; however, unlike the formally defined policies and regulations that govern organic agriculture, the label organic lawn management has not been formally defined and is used to describe a variety of practices. Neighborhoods, cities, states, and provinces across North America are adopting policies regulating the use of pesticides and fertilizers in the landscape. In addition, a small but growing number of public institutions and individual consumers are successfully adopting alternative lawn care methods, including organic lawn care. Although perceived as environmentally friendly, the effects of organic management on insect diversity and pest management remain understudied. Organic lawn management may lead to increased lawn plant diversity, which in agroecosystems has enhanced ecological services provided by beneficial insect species. Effects of vegetative diversity on lawn pest management are less clear. Vegetative complexity and increased plant diversity in urban landscapes may enhance insect predator efficacy. The diversity of predatory insects varies between turfgrass varieties in response to prey populations. Mortality of insectivorous and granivorous ground beetles (Carabidae) while not directly impacted by pest management programs in turfgrass may be indirectly impacted by a reduction in the prevalence of plant species that provide alternative food resources. Previous studies have focused on herbivorous insects as well as predatory and parasitic insects that feed on them. Future studies should assess how lawn plant diversity resulting from organic management practices might impact insect communities in turfgrass.

“The End is HERE”

On the Last day there would be a potluck and a drawing for some free appliances and $100 in cash. It was clear, though, that those still around in September 2004 could hardly wait for this drawn-out shuttering finally to be over. Crews were taking down the lighting, removing tables and cabinets, and gathering screws and air gun bits to toss in the garbage. “I don’t know if they are going to start with fresh tools down there in Reynosa or what the deal is,” Tracy Warner said. The crews also asked workers to remove photographs and newspaper clippings from their workstations. “They are dismantling it all around us, like they can’t wait for us to get out of there.” The lawn outside, usually covered in pop cans, plastic wrappers, and cigarette butts, was cleaned up and sprayed green by Chem Lawn. Management was trying to sell the old place. Warner’s imminent layoff was part of a sea-change in Illinois in the first years of the new millennium. The pace of the hollowing out of manufacturing in the fourth-largest manufacturing state in the country had been unprecedented. From June 2000 to November 2003, Illinois lost more than 100 manufacturing jobs a day, or one out of every six. Gone were over 150,000 jobs in a state of 12,500,000. In Rockford, the machine-tool industry wilted, and unemployment spiked at over 11 percent. In Harvard, located near the Wisconsin border, Motorola closed its cellphone plant. Developers wanted to turn the site into the world’s largest indoor water park. In Peoria, Decatur, and Kankakee, laid-off workers applied for jobs at Walmarts and Home Depots that would pay them maybe half their former wage. In suburban Chicago, Winzeler Gear went from making 2 million gears a month with fifty-five workers to making 16 million a month with thirty-five employees. A robot the size of a minivan increased the factory’s output while also eliminating human labor. Even with the productivity boost, the owner doubted the company would be able to stay competitive.

Growth inhibitors in turfgrass

Well-maintained lawns are comfortable and safe places for leisure activities and sports practice, and they also bring environmental benefits; for example, they reduce soil exposure to erosion and releases atmospheric CO2, thus reducing the greenhouse effect. However, regardless of the purpose of use or the choice of the plant species to form the lawn, the highest costs involve cutting that is needed to keep the turfgrass at its appropriate height. Successive lawn cutting operations are necessary basically because of the vegetative and reproductive growth of turfgrass which, in Brazil, occurs mainly from October to March. Expenditures with successive mechanical cuttings have fostered the search of alternative procedures to keep lawn plants at appropriate height, such as the use of plant growth inhibitors, an increasingly interesting procedure. Since the use of this technology in Brazil is still at its early stage, the aim of this literature review is to examine aspects associated with lawn management by using growth inhibitors. Another alternative is to increase the knowledge of the classification and rational application of the different compounds currently available in the market.
