Dinitroaniline-herbicide resistance in goosegrass (Eleusine indica) : ecophysiological aspects

Creator:: Valverde, Bernal E.
Abstract:: Growth of individual goosegrass (Eleusine indica (L) Gaertn.) plants of three dinitroaniline-herbicide resistant (R) and three susceptible (S) biotypes from North Carolina, South Carolina, and Mississippi was analyzed in greenhouse experiments. Leaf area and biomass measurements, including root, shoot, above-ground, and total dry weights were similar among the biotypes studied....

Glyphosate Resistance and Tolerance in Italian Ryegrass (Lolium perenne spp multiflorum) : Termination Treatments, Cultivar, and Resistance Evaluation

Creator:: MacPherran, Robert Chase
Abstract:: Annual ryegrass, or Italian ryegrass (Lolium perenne spp. multiflorum), has been the most stable, in terms of acres, grass produced for the past 25 years in Oregon. Increased interest in Italian ryegrass as a cover crop has increased demand for quality seed. Ideal Italian ryegrass cover crop cultivars are named...

Investigation of inheritance of glyphosate resistance and the mechanisms of glufosinate resistance in Italian ryegrass (Lolium perenne L. spp. multiflorum (Lam.) Husnot) populations

Creator:: Avila Garcia, Wilson Vidal
Abstract:: Italian ryegrass populations have been identified with evolved resistance to glyphosate in orchards with a history of glyphosate use. Two of these populations were selected to investigate the inheritance of glyphosate resistance. The mechanisms involved in the herbicide resistance were an altered target site for the population SF and reduced...

Introgression and Evaluation of Wheat (Triticum aestivum L.) Conferring Resistance to Quizalofop-p-ethyl Herbicide

Creator:: Richter, Colette M.
Abstract:: Wheat (Triticum aestivum L.) is one of the most important crops in the world supplying about 18.8 percent of the world's caloric energy supply and 20 percent of the world's protein. In the Pacific Northwest (PNW), over one million hectares of wheat are grown every year. Wheat production is typically...

Elicitors: A Novel Tool for Controlling the Colorado Potato Beetle Leptinotarsa decemlineata Say (Coleoptera: Chrysomelidae)

Creator:: Butcher, Alexander M.
Abstract:: Over the last several decades, potato production has increased globally as it has been recognized as an important component to improving food security. However, potato production has been continuously challenged by pests. Current pest management practices rely heavily on chemical pesticides. Unfortunately, the overuse of pesticides can be harmful to...

Frequency, Distribution, Ploidy Diversity and Control Options of Herbicide Resistant Italian Ryegrass (Lolium perenne L. spp. multiflorum (Lam.) Husnot) Populations in Western Oregon

Creator:: Bobadilla, Lucas K.
Abstract:: Italian ryegrass (Lolium perenne L. spp. multiflorum (Lam.) Husnot) is one of the most troublesome weeds with respect to herbicide resistance selection. Some reasons for this are the numerous documented cases of multiple and cross herbicide resistance and some of the biological characteristics of this species, such as wind cross-pollination...

Non-herbicidal effects of dinoseb on winter wheat yields

Creator:: Valverde, Bernal E.
Abstract:: A series of experiments were conducted from 1983 to 1985 to determine the effects of dinoseb [2-(1-methylpropyl)-4,6-dinitrophenol] on winter wheat (Triticum aestivum L. em Thell) yields. Field trials on dinoseb timing and dinoseb plus supplemental pesticides were established in an effort to elucidate the possible factors involved in the yield...

Retention of wheat alleles in imidazolinone-resistant wheat x jointed goatgrass recurrent backcross generations

Creator:: Kroiss, Lori Jennifer
Abstract:: The retention of D genome wheat alleles in the progeny of imidazolinoneresistant wheat (R-wheat) and jointed goatgrass hybrids backcrossed to jointed goatgrass was documented in this study. Resistance to the imazamox application was used as a marker for the imidazolinone-resistance gene. Fourteen simple sequence repeat (SSR) markers, for the wheat...
