Crop Monitoring is Number One Priority

Published on Wednesday, July 13, 2016

Our area struggled this spring during crop establishment. We experienced soil-borne fungal diseases and cool air temperatures coupled with lots of rain, which has delayed growth and development. We had about three planting windows. Amazingly, the earliest planted crops (both corn and soybeans) look the best at this time. The fields needing replanting (additional soybean populations) were completed about June 1.

Now, crop monitoring should be first priority. As the crop races to reproductive phases, insect, disease, weeds, and fertility aspects should be addressed and corrected. In particular, making proper herbicide applications (as label states) to reduce any potential injury issues are of utmost priority. Late season nitrogen (N) applications may be necessary given rainfall events earlier this spring. You may want to consider doing a Pre-sidedress Nitrate Test (PSNT) to see where N levels are in your fields.

Foliar/plant tissue sampling should be done on soybeans to see if sufficient nutrients are present as well. Foliar applications in R1 to R3 growth stages seem to be the sweet spot for best ROI of fungicides and micronutrients. Our multi-year Practical Farm Research (PFR)® studies provide great information for product selection and application timing. If you have any questions, call me at 317-694-7298.
