Risk Statement

Local harmfulness

Algeria: Bromus lanceolatus is a minor "weed". Uncommon and not very abundant, it does not generally constitute a nuisance for the crop. The situation is completely different for B. madritensis L. and B. rigidus which are major "weeds" of cereal crops.

📚 Uses and Management

Local control

Algeria: Bromus lanceolatus is controlled by the false seeding technique, a destocking technique to limit weed infestation in winter cereals. Active ingredients such as clodinafop-propargil + cloquintocet-mexyl, diclofopmethyl + fenoxaprop-P-ethyl + mefenpyr-diethyl, clodinafop-propargil, diclofopmethyl, sulfosulfuron, popaquizafop, bentazone, glufosinate ammonium, etc. control the adult stages.
