A University of Missouri extension weed specialist says using cereal rye as a cover crop can help reduce waterhemp pressure without building its herbicide resistance.
Mandy Bish said fall seeded cereal rye accumulates biomass over the winter that suppresses waterhemp emergence. And she tells Brownfield pairing cover crops with a residual herbicide can ‘greatly reduce’ waterhemp germination.
“The less waterhemp that germinates, the less waterhemp you’re having to spray with post-emergent herbicides,” she said.
