Wirkung des Gerätes CombCut auf die Ackerkratzdistel bei verschiedenen Getreidearten

Summary translation

In organic farming, Canada thistle is difficult to control. The thistle`s development may be decreased with the innovative cutter CombCut during growing cereal. Field trials were conducted over a period of three years nearby Freising to test the impact of CombCut to thistle. The thistle was cut every year above the cereal. Additionally, in one year, the thistle could be cut twice directly in cereal population. The CombCut obviously decreased to the thistle´s development. Cutting directly in cereal population harmed the thistle stronger or tended to result higher yield (p = 0.09) than cutting above the cereal. However, yield without weed infestation was two or three times higher as with thistle infestation. Hence, top priority is accurately to conduct all activities to prevent thistle`s establishment.
