Weeds occur in patches across landscapes and vary in species, density, time of emergence, and growth rate depending on location. Precision weed management accounts for natural and management-induced variation to optimize inputs (control methodology) to reduce weed presence and improve crop yields across an area.

Modelling for precision weed management.
Ciba Foundation symposium, 1997Recently, the need for the development of weed management systems with a reduced dependency on herbicides has increased because of concern about environmental side-effects and cost. The development of such systems requires new strategies based on improvements with respect to (1) prevention, (2) decision making and (3) weed control technology.

Economic analysis of precision weed management
Cereal Research Communications, 2009The practical implementation of precision crop production nowadays is becoming more and more widespread. Numerous experiments and farmers’ practical experiences verify the positive impacts of precision nutrient supply on farming. Precision weed control started to spread later, partly due to technical difficulties, partly to the lack of necessary ...

Analysis of band spraying and precision weed management
Cereal Research Communications, 2007For preserving sustainability in agriculture we need to reduce the level of industrial inputs as much as possible without substantially lowering the profitability of farming (not talking about organic production in this case). Herbicides are used in the biggest quantity in today’s agriculture.

Precision farming for weed management: techniques
Gesunde Pflanzen, 2008Site-specific weed control techniques have gained interest in the precision farming community over the last years. Managing weeds on a subfield level requires measuring the varying density of weeds within a field. Decision models aid in the selection and adjustment of the treatments, depending on the weed infestation.

DEVELOPMENT OF A PRECISION SPRAYER FOR SITE-SPECIFIC WEED MANAGEMENT
Transactions of the ASAE, 1999A machine-vision-system-guided precision sprayer was developed and tested. The long-term objectives of this project were to develop new technologies to estimate weed density and size in real time, realize site-specific weed control, and effectively reduce herbicide application amounts for corn and soybean fields. This research integrated a real-time

Remote sensing for precision weed management
Pest Management ScienceAbstractHerbicides are important for controlling and avoiding the impact of weeds in reducing crop productivity. Traditionally, herbicides are applied uniformly over crop fields. With the advancement of precision agriculture, it is now possible to apply herbicides site‐specifically with precision operations over the crop fields.

Weed populations in arable elds have often been found to be distributed heterogeneously in time and space (Marshall, 1988; Thornton et al., 1990; Wiles et al., 1992; Johnson et al., 1996; Gerhards et al., 1997; Christensen and Heisel, 1998; Nordmeyer et al., 2003; Gerhards and Christensen, 2003).

The value of precision for image-based decision support in weed management
Precision Agriculture, 2017Decision support methodologies in precision agriculture should integrate the different dimensions composing the added complexity of operational decision problems. Special attention has to be given to the adequate knowledge extraction techniques for making sense of the collected data, processing the information for assessing decision makers and farmers ...
