Abstract:: Jointed goatgrass (Aegilops cylindrica Host.) is a serious weed problem in wheat (Triticum aestivum L.) production in the United States. Studies were conducted to determine the outcrossing rate, competitive ability, and effectiveness of certain control practices on jointed goatgrass. A field study was conducted over two years at four locations...

Abstract:: Downy brome (Bromus tectorum. L.), a serious grass weed in eastern Oregon can be partially controlled in wheat by metribuzin [4-amino-6-tertbutyl- 3-(methylthio)-as triazin -5(4H)-one]. However, cultivars of many crops Lave been reported to differ in their level of tolerance to metribuzin. This lack of tolerance has led to the investigation...

Abstract:: Scouringrushes (Equisetum hyemale L.; E. xferrissii Clute; E. laevigatum L.) are ancient perennial seedless vascular plants historically associated with wetlands, low-lying roadsides or field margins with more plant available water. There has been little research conducted on scouringrush species in the context of agricultural production because traditional farming practices confined...

Abstract:: Weedy rye (Secale spp.) is a weed in the winter-wheat- growing regions in the Pacific Northwest and surrounding regions. Ethiazin (4-amino-6-(1,1-dimethylethyl)-3- (ehtylthio)-1,2,4-triazine-5 (4H)-one) has shown selective control of weedy rye in the cultivar 'Stephens', (Triticum aestivum). Field, greenhouse, and outdoor pot experiments were conducted to determine factors influencing selectivity. Field...

Abstract:: Many non-native weed pests of food, fiber, and nursery crops pose threats to U.S. environment and agriculture. Noxious weed regulations play an important role in preventing the introduction and spread of non-native plants, thereby protecting the local biodiversity, environment and economic activities. However, these regulations could also hamper agricultural trade....
