چکیده

Weed control is generally the first major decision to be made once alfalfa has germinated. Managing weeds in a timely manner is necessary to provide maximum production of high quality alfalfa hay. A poor weed management decision can lead to stand loss, poor quality hay, unacceptable weed control, alfalfa injury and a loss of money. Herbicides are applied to 75% of newly planted alfalfa in California and considered an integral part of a weed manage system that compliment cultural practices. In the last decade several new post emergence herbicides, imazethapyrPursuit, imazamox-Raptor, clethodim, and sethoxydim Prism and Poast have significantly changed weed management systems from preplant applied herbicides to post emergence herbicides expanding control of many broadleaf weeds and grasses. Roundup Ready alfalfa became commercially available in 2005 offering a new weed control system using genetically engineered glyphosate tolerant alfalfa. The impact that herbicide tolerant crops have had on other commodities is remarkable. In 2004, an estimated 70 percent of the cotton acreage, 90 percent of the soybean acreage, 65 percent of the canola acreage, and 40 percent of the corn acreage in the United States were planted with varieties genetically altered for herbicide tolerance.

A quantitative competitor PCR assay to detect genetically modified roundup-ready soybeans in commercially sold foods in Iran

Due to ever-increasing global diffusion and related socio-economic implications, the detectionof genetically modified organisms (GMOs) is very important. In this study, we design a plasmidcontaining two genes in mutated form as construct-specific (cp4 epsps) and event-specific(pd35S). It is applied for quantitative-competitor (QC) PCR as a simple and reliable method forthe detection of GM food....

Herbicide Tolerant Soybeans: Why Growers Are Adopting Roundup Ready Varieties

Soybean growers have adopted herbicide tolerant varieties at a rapid rate. While some potential cost savings may have driven adoption, the primary reason growers are switching to new programs is the simplicity and flexibility of a weed control program that relies on one herbicide to control a broad spectrum of weeds without crop injury or crop rotation restrictions. Roundup Ready weed control p...
