Weeds are a major constraint to the success of dry-seeded rice (DSR). The main means of managing these in a DSR system is through chemical weed control using herbicides. However, the use of herbicides alone may not be sustainable in the long term. Approaches that aim for high crop competitiveness therefore need to be exploited. One such approach is the use of high rice seeding rates. Experiment...

Weed competes with crops for water, nutrients and light so weed infestation is one of the major threats to crop. Present investigation was aimed to asses the comparative efficacy of different herbicides for weed management in wheat crop under agro-climatic conditions of Pakistan. This experiment was laid out in a randomized complete block design (RCBD) design with five replications. Different h...

Weed management is an important consideration in implementing new cropping systems. In the semi-arid region of the Pacific Northwest, grower interest is increasing in no-till spring cropping systems because of wind erosion from traditional winter wheat Triticum aestivum L./dust-mulch fallow (WWF). However, no-till represents a major shift in production practices and is likely to produce new wee...

Population models are particularly helpful for understanding long-term changes in the weed dynamics associated with integrated management (IWM) strategies. IWM practices controlling L. rigidum of high importance, mainly due to its widespread resistance that precludes chemical control as a single method. The objective this contribution is simulate different scenarios special emphasis on impact l...

Exotic invasive plants present one of the greatest challenges to natural resource management. These weeds can alter entire communities and ecosystems, substantially degrading important ecosystem services such as forage for wild and domestic herbivores, water and soil quality, recreational values, and wildlife habitat. Traditionally, weed management in natural areas has focused on removing the t...

Understanding the impact of farming practices on composition weed communities has important implications for sustainability management strategies. This study analyses data from a 40-year experiment established at two sites in Czech Republic 1972. The herbicide strategies was evaluated multi-crop rotation (MCR) with 50% cereals, and simple crop rotations (SCR) 75% cereals. following were compare...

INTRODUCTION The Autonomous Platform and Information system (API, DIAS, Denmark) was used as tool for comparing two successful weed detection algorithms: the shape based weed recognition based on colour imaging developed at DIAS, Denmark, and the spectral weed detection system developed at the KULeuven, Belgium.

Soybean growers have adopted herbicide tolerant varieties at a rapid rate. While some potential cost savings may have driven adoption, the primary reason growers are switching to new programs is the simplicity and flexibility of a weed control program that relies on one herbicide to control a broad spectrum of weeds without crop injury or crop rotation restrictions. Roundup Ready weed control p...

use of atrazine in the Midwest would have important economic consequences for farmers, consumers, and the environment. These consequences can only be evaluated with cooperation between economists and weed scientists. The weed control choice set available to farmers cannot be observed through deductive research. Economists and weed scientists worked together to identify all possible weed control...
