the use of more competitive species and cultivars in small grain cereal production may help to develop production systems that require less herbicide. this study was designed to identify root and shoot characteristics of cereal seedlings that would allow distinguishing the more competitive (mc) cultivars from the less competitive (lc) ones. two growth cabinet trials were conducted using four cr...

Our long-term goal is to develop a Swedish winter oat (Avena sativa). To identify molecular differences that correlate with winter hardiness, a winter oat model comprising of both non-hardy spring lines and winter hardy lines is needed. To achieve this, we selected 294 oat breeding lines, originating from various Russian, German, and American winter oat breeding programs and tested them in the ...

adjutants' ability in enhancing the performance of herbicides is a major priority in adjuvant research. to identify an appropriate adjuvant for pinoxaden and clodinafop propargyl herbicides against littleseed canarygrass (phalaris minor retz.), common wild oat (avena fatua l.) and ryegrass (lolium temulentum l.), three separate experiments were conducted under greenhouse conditions. in all...

in order to study the effect of nitrogen on competition between wild oat (avena fatua) and wheat (triticum aestivum) at vegetative growth stage, a factorial experiment was conducted based on completely randomized block design with three replications in research greenhouse of faculty of agriculture, at ferdowsi university of mashhad in 2008. first factor was five densities (0, 2, 4, 6 and 8 plan...

nowadays herbicide reduction and different approaches leading to this goal like split application have been brought to attention. two green house experiments were carried out to investigate the efficiency of single and split application of mesosulfuron-methy+iodosulfuron methyl to control wild oat (avena ludoviciana). the influence of applications intervals and the ratios of the two application...

introduction integrated weed management is based on combination of several management methods, while reducing the rate of the use of herbicides, will result in efficient management and sustainable weed control. ability of crop tolerance and prevent weed growth are two important traits in weed competition. an appropriate and suitable cultivar, has high yield potential in the presence of weed and...

Introduction: Wild oat has become an invasive and economically important weedy species in most cereal growing areas of the world, including the Red River Valley of Minnesota and North Dakota. Approximately 79% of the wheat and 72% of barley acres seeded in northwestern Minnesota are infested with wild oat. In the past, wild oat has been effectively controlled with herbicides, and as a result li...

abstract three separate greenhouse experiments were conducted in the greenhouse facilities of the iranian plant protection research institute, tehran, to study the efficacy of some accase inhibiting herbicides for control of resistant based on mechanism, resistance based on enhanced metabolism and susceptible wild oat biotypes. in each experiment, biotypes were treated separately by 17 herbicid...
