Glyphosate-resistance in Italian ryegrass (Lolium multiflorum): evaluation and investigation of the mechanisms of resistance

Creator:: Perez-Jones, Alejandro
Abstract:: A suspected glyphosate-resistant Italian ryegrass (Lolium multiflorum) (OR) population was collected from a filbert (Corylus avellana L.) orchard near Portland, OR. Based on the dose-response experiments conducted in the greenhouse, it was found that the suspected glyphosate-resistant population was approximately fivefold more resistant to glyphosate than the susceptible (S) population....

Characterization of strains of Scenedesmus resistant to the herbicide DCMU, (3-(3,4-dichlorophenyl)-1,1-dimethylurea)

Creator:: Smith, Muriel K.
Abstract:: Three DCMU resistant mutants of the green alga Scenedesmus obliquus D₃ are characterized. The mutants exhibit a ten fold greater resistance to DCMU than the wild type strain; this is comparable to the level of DCMU resistance detected in other DCMU resistant algae. In whole cell reactions, as well as...

Early detection of weed resistance : pattern-thinking and rapid microcalorimetric assay

Creator:: Suwanagul, Duangporn
Abstract:: Weed resistance is usually diagnosed after a weed control practice has lost efficacy and weed populations begin to increase rapidly. Prediction and validation in the field at a very early stage of resistance development is a promising method for preventing an uncontrollable problem. Pattern-thinking helped individuals connect their experience of...

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....

The acetohydroxyacid synthase gene family its role in herbicide resistant sunflowers

Creator:: Hawley, Robin M.
Abstract:: Resistance to acetohydroxyacid synthase (AHAS)-inhibiting herbicides has been reported in over 90 weedy species, including wild sunflower biotypes, since the herbicides were developed in 1982. The AHAS gene family in sunflower, consisting of three paralogs AHAS1 , AHAS2, and AHAS3, has been targeted for inducing herbicide resistance. A polymorphism identified...

Molecular basis of target-site resistance to acetolactate synthase-inhibiting herbicides in mayweed chamomile (Anthemis cotula L.)

Creator:: Intanon, Suphannika
Abstract:: Mayweed chamomile (Anthemis cotula L.) is an annual weed in the Asteraceae family that is commonly found in fields of the Pacific Northwest. Acetolactate synthase (ALS)-inhibiting herbicides are frequently used to control a broad spectrum of weed species including mayweed chamomile. Seeds of four biotypes of mayweed chamomile (KJ, KL1,...

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...

Establishment tolerance of six native sagebrush steppe species to imazapic (PLATEAU®) herbicide implications for restoration and recovery

Creator:: Bekedam, Steven
Abstract:: Scientists and land managers realize that integrated weed management (IWM) strategies are needed to attain successful and lasting improvements of weed infested landscapes. At this time no broadly reliable and environmentally safe IWM strategy has been developed to control exotic annual grasses that dominate many ecosystems of the northern Great...

Multiple-resistant Italian ryegrass (Lolium perenne spp. multiflorum) populations in Oregon

Creator:: Liu, Mingyang
Abstract:: Italian ryegrass (Lolium perenne spp. multiflorum) is a common weed management problem in turfgrasses, cereals and non-crop areas in the United States. In Oregon, the number of populations with multiple-resistance continues to increase. To manage these resistant populations, the resistance patterns must be determined. In this study, five Italian ryegrass...
