production more profitable by reducing the losses and costs above all of weed control, thus, releasing time and labor to be used elsewhere in production ( Melander et al., 2005 ). Weeds limit crop yield and quality, and weed control is one of the most

period is marked by an increase in weed populations when the transition is managed by growers who are accustomed to using synthetic herbicides to control weeds ( Martini et al., 2004 ). Few organically acceptable herbicides have been shown to be

application with a rototiller. The plots were not tarped. Results and Discussion All the treatments controlled 80% to 100% of annual weeds, except IM 50% + CP 50% (200 lb/acre, tarped) and MS (1:4 water, 75 gal/acre, not tarped), which had poor control of

control of winter weeds on zoysiagrass turf ( Harrell et al., 2005 ; Johnson, 1980 ; Vargas and Turgeon, 2004 ). However, the main strategy adopted by golf course superintendents in this region is winter application of the non-selective herbicide

the completion of the study, all aboveground growth from weeds located in a 6.5-ft section in the center of each plot, measuring the entire width of a plot (≈2 ft), was harvested and dried in an oven at 75 °C for 1 week to obtain weed biomass. At

Smooth crabgrass and goosegrass are problematic weeds in creeping bentgrass in the transition zone, an area that rests between the southern United States where warm-season grasses dominate, and the northern United States where cool-season grasses

the effect of mulch and weed control on shrub growth, photosynthetic gas exchange, foliar nutrition, soil moisture, soil pH, and populations of common weeds. Materials and Methods Site and treatments. The study was installed in Aug. 2004

Soilborne fungal pathogens, nematodes, and weeds represent some of the most important biotic factors limiting vegetable crop production and profitability in the world. After the phaseout of methyl bromide, although other chemical soil fumigants (CSF

occupies the soil for the preceding part of the season, weeds can grow and contribute large amounts of seeds to the soil weed seed bank ( Kumar et al., 2009 ). During this summer fallow season, many midwestern U.S. vegetable growers manage weeds by means of

Cover crops improve soil health and can be beneficial for weed management by suppressing weeds at different stages. During the cover crop growth period, cover crops can reduce weed growth and seed production through direct competition or
