Considerations: Any time annual ryegrass is used, spring management has to be a main priority. Keep ryegrass from going to seed at all costs. Annual ryegrass not terminated can have adverse effects on any subsequent grass crops. The use of ryegrass blends have given ryegrass a bad reputation – make sure it is a single, respected variety. Multiple maturities make control even more complex. Balansa is a prolific re-seeder; termination or grazing prior to flowering will remove the risk. Early indications point to balansa clover tolerating cold temperatures better than crimson clover. The trade-off is balansa might not establish as quickly. When utilizing balansa clover, the goal should be allowing balansa to grow as much as possible into spring.

Termination: Radish will terminate with multiple nights in the teens. If radish overwinter, glyphosate and 2,4-D provide effective control. If balansa clover overwinters, herbicide applications including glyphosate prior to flowering have been effective. For annual ryegrass termination, using glyphosate by itself or with other grass killers can be used, but several key management criteria need met to ensure success.
