Expression of allelopathy in the soil environment: soil concentration and activity of benzoxazinoid compounds released by rye cover crop residue

Abstract

Rye (Secale cereale L.) residue is known to suppress weeds in agronomic environments and to produce benzoxazinoid (BX) compounds which are phytotoxic. Experiments were conducted to determine the duration of indicator plant inhibition and BX soil concentrations in response to field incorporated or surface rye residue. Surface rye residue was highly… (More)
