abstract

Chemical weed control is possible in direct seeded asparagus, according to these tests. However, a successful program may require a pre-emergent chemical that will give complete control for at least 4 to 6 weeks after crop emergence, and then a layby treatment for the rest of the season. Additional tests are needed before recommendations can be made. The University of California has no recommendations at present for herbicides in direct seeded asparagus planting. Federal registrations are available only for Vegiben and Paraquat when used pre-emergent to the asparagus.
