Risk Statement
Local harmfulness
Algeria: Bromus rigidus is a major "weed". It is one of the most harmful species of Algerian field crops because it can colonise practically all ecological environments (very frequent species), and its great adaptation to the agricultural environment gives it a very important potential of invading plots (very abundant species). Typical species of intensified cereals and its very high density places it among the most harmful grasses.

📚 Uses and Management
Management
Local control
Algeria: The false seeding technique, a destocking technique, has been specially developed to limit weed infestation in winter cereals. Active ingredients such as bentazone, clodinafop-propargil + cloquintocet-mexyl, diclofopmethyl + fenoxaprop-P-ethyl + mefenpyr-diethyl, clodinafop-propargil, diclofopmethyl, iodosulfuron-methyl-sodium + amidosulfuron-sodium + mefenpyr-diethyl, popaquizafop, pyroxsulam + cloquintocet-methyl, sulpho-sulfuron, etc. control adult weeds. are used to control adults.
