Decisions in Late Season Planting

Continued rain delays during the holiday weekend have growers hustling to get back into fields. As you continue to plant or replant, don’t forget to review your current crop plan and scout already emerged crops.

Review your crop plan

June 1 is our general rule of thumb when making the decision to switch to a shorter-season hybrid. If you’re in Kentucky, or the southern parts of Indiana and Ohio, you can keep with your current hybrids until about June 5. In Michigan and the northern parts of Indiana and Ohio, we recommend changing to a shorter-season hybrid this week.

If you’ll be spot planting fields, we recommend you calculate the growing degree days (GDDs) the field has received and try to match that to the hybrid you’ll be spot planting. This will hopefully allow the field to develop at the same pace once the spot plants emerge.

If your planting is delayed until the end of the first full week in June (next week) that’s when we recommend you consider changing your crop plan and planting soybeans instead of corn. Give us a call to discuss this topic before you make any decisions.


Getting the crop in the ground is top-of-mind for most of us, but don’t forget to scout the crops that have emerged. Walk the entire field while scouting, don’t overlook issues by just driving past the field.

We recommend to scout for seedling blight, slugs, armyworm and black cutworm in the coming weeks. Seedling blight has been spotted in heavier soils and wet spots. Slug damage is more prominent in no till and cover crop acres and intensified in cool, wet conditions. There is no good remediation for slugs; two options being replant and to let it be. Given decent growing conditions, plants will outgrow slug damage. We have seen armyworm and black cutworm feeding in various locations, north to south, with a few outbreaks heavy enough to warrant treatment.
