Growers in the United States spend well over $6 one thousand million each year to control weed populations (NCFAP 2003).

In the upcountry Northwest, traditional crop production practices have problematic the use of tillage and stubble burning to, in part, control weed populations. In the drier regions, fallow fi elds are often used to conserve soil moistur! e for prospective crops. These practices micturate some unique problems with the perplexity of weeds. Weed management is a considerable challenge for creating sustainable dryland cereal-based cropping systems in the Northwest. Problems with downy brome, Russian thistle, jointed goatgrass, wild oats, and herbicide resistance scupper semipermanent sustainability because of the need for tillage and herbicides to control weed populations. many scientists in the Inland Northwest are studying...If you want to get a full essay, order it on our website: OrderCustomPaper.com
