Growth in the presence of sucrose was shown to confer to Arabidopsis thaliana (thale cress or mustard weed) seedlings, under conditions of in vitro culture, a high level of tolerance to the herbicide atrazine and to other photosynthesis inhibitors. This tolerance was associated with root-to-shoot transfer and accumulation of atrazine in shoots, which resulted in significant decrease of herbicid...

Imazosulfuron is a new herbicide recently labeled in drilland water-seeded rice under the trade name LeagueTM. Research was conducted to understand the best fit for imazosulfuron in Arkansas rice culture, prior to its anticipated launch in 2011. Specifically, research was conducted (a) to understand the influence of application rate and timing on control, (b) to evaluate the effectiveness of im...

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...

In 2007 and 2008, field trials were carried out with different standard and drift-reducing nozzles in sugar beet, maize, chicory, Belgian endive (all herbicide applications), wheat (fungicide application) and potatoes (Haulm killing herbicide application). The effect of nozzle type (standard flat fan, low-drift flat fan, air injection), nozzle size (ISO 02, 03 and 04) and application volume on ...

Phalaris brachystachys is a common and troublesome weed in winter cereals in Mediterranean countries. A deterministic model was developed to simulate P. brachystachys seedbank dynamics in the wheat-sunflower rotation, a commonly practiced cropping system in southern Spain, under different herbicide-based management scenarios: no herbicide application, full herbicide dose (standard rate) and two...
