Eignung unterschiedlicher Applikationsköpfe für die Ampferbekämpfung mit Heißwasser

Summary

As already shown in former investigations, thermal treatment with a hot water/steam mixture can be an appropriate method to control dock plants (Rumex obtusifolius). Thereb,y the application method can be a key technique to acquire both good treatment effects and low working time and energy requirements. Five application techniques were compared in this investigation. A nozzle with rotating pencil jet was identified as the one with the best performance. This variant requires 1.6 l of 90 °C hot water per plant, applied at mean 15 seconds. The average fuel consumption to heat the water came up to 0.016 l Diesel per plant.
