Row cultivation, along with herbicides, can provide a cost-effective, integrated weed management solution. Cultivate deep enough to remove small seedlings, but not so deep as to bring up untreated soil and promote a secondary flush. However, in historically no-till fields, cultivation of any kind will distribute the seed within the soil profile, increasing seed longevity and making eradication more difficult. Cultural Practices Corn should be planted as close to the final tillage pass or burndown treatment as possible. This allows corn to get a head start or even start with woolly cupgrass, which will lend increased flexibility to the timing of herbicide treatments or cultivation.
