Precision weed control in sunflower and maize - experiences from Hungary
2012
Komives, Tamas | Reisinger, Peter
In recent years, a Hungarian private farm in Zimany (Southern Hungary) systematically built-up and developed its spatial information infrastructure and enabled us to carry out research on and development of site-specific weed management methods. Over the past four years, our goals were to improve weed control efficacy and to reduce the amount of herbicides applied. We a) developed an off-line, map-based method for pre-emergent precision herbicide treatments to control weeds in maize and sunflower (our application algorithm is based on the humus content and an empirical plasticity index of the soil), and b) in on-line precision post-emergent inrow treatments in maize we used a novel approach to mount mechanically shielded WeedSeeker (NTech Industries) sensor-sprayers on a precision cultivator (Garford Farm Machinery) in order to apply a non-selective (total) herbicide (glyphosate) safely under the leaf canopy.
