Abstract

The resistance development of Alopecurus myosuroides HUDS. (blackgrass) against ALS inhibitors may possibly be accelerated due to different pretreatments. In this context, sequential applications of ALS inhibitors in a culture are thought to be critically. To answer this question, a special bioassay has been developed. In a first step, A. myosuroides were sequentially treated with different ALS inhibitors and propagated under standardized conditions in the open field using breeding methods. Seeds of these plants were collected and their susceptibility towards ALS inhibitors was determined.
