  In order to reduce the herbicide rate, the combination of cultivation and eradicane herbicide application was tested under field conditions. Treatments including tillage practices of without cultivation, one cultivation and two cultivation and eradicane herbicide application levels of 0, 1.5, 3, 4.5, 6 Lha -1 were tested . Eradicane herbicide was used before plantation. Cultivation treatments...

Flazasulfuron is a selective herbicide registered for use in warm-season turfgrass. Concerns have been raised over its mobility surface water runoff. Studies were conducted Blacksburg, VA and Charlottesville, to evaluate injury Lolium perenne L. (perennial ryegrass) downslope of plots treated with transition-assisting herbicides, including flazasulfuron, pronamide, trifloxysulfuron sodium. (52 ...

Lolium perenne L. (perennial ryegrass) commonly contaminates Agrostis stolonifera (creeping bentgrass) on cool-season golf courses. Currently, few herbicide options are available for the selective control of in A. stolonifera. Previous studies have indicated that flazasulfuron could be a potential solution, so trials were conducted at three sites Blacksburg, VA to evaluate rates and sequential ...

Target-site and non-target-site herbicide tolerance are caused by the prevention of herbicide binding to the target enzyme and the reduction to a nonlethal dose of herbicide reaching the target enzyme, respectively. There is little information on the molecular mechanisms involved in non-target-site herbicide tolerance, although it poses the greater threat in the evolution of herbicide-resistant...

The interaction between environment and genetic traits under selection is the basis of evolution. In this study, we have investigated the genetic basis of herbicide resistance in a highly characterized initially herbicide-susceptible Lolium rigidum population recurrently selected with low (below recommended label) doses of the herbicide diclofop-methyl. We report the variability in herbicide re...

Garlic mustard, an invasive exotic biennial herb, has been identified in the Upper Peninsula of Michigan, but is not yet widely distributed. We tested the effectiveness and impact of management tools for garlic mustard in northern hardwood forests. Six treatment types (no treatment control, hand-pull, herbicide, hand-pull/herbicide, scorch, and hand-pull/scorch) were applied within a northern h...

Herbicide resistant crops are commercially advantageous for efficient field productivity by enabling use of nonselective herbicides for weed management. Herbicide resistant trees could be used to improve productivity and reduce the costs of forest management through to the first and second years post tree establishment. We describe the introduction of the phosphinothricin acetyltransferase (bar...

Methods for woody plant herbicide screening were assayed with the goal of reducing resources and time required to conduct preliminary screenings for new products. Rapid screening methods tested included greenhouse seedling screening, germinal screening, and seed screening. Triclopyr and eight experimental herbicides from Dow AgroSciences (DAS 313, 402, 534, 548, 602, 729, 779, and 896) were tes...

Herbicide mixtures are commonly used in agriculture to broaden the spectrum of weed control. The interactions or the combinations may be desirable or undesirable. Acetachlor at 150g/ha applied and ready mix application of anilofos and ethoxysulfuron at 780 g /ha provide effective control of weeds with higher grain yield. Tank mix application of metribuzin with isoproturon at 1.0 kg/ha, clodinof...

Kochia [Bassia scoparia (L.) A.J. Scott] is an invasive C 4 tumbleweed in the Great Plains of North America, where it impedes crop harvest and causes significant yield losses. Rapid evolution spread glyphosate- acetolactate synthase (ALS) inhibitor-resistant kochia western Canada limit herbicide options available for control these biotypes field pea (Pisum sativum L.); one predominant pulse cro...
