Corn
Growth & Development
Corn development continues to vary throughout the county. Last week I highlighted the R2 (Blister) growth stage. R3 is the next stage, occurring approximately 20 days after silking.
R3 – Milk Stage
- Occurs approximately 18‐20 days after silking.
- The kernel is colored yellow with the inside containing ‘milky’ white fluid.
- Kernel moisture content is approximately 80%
- Starch is beginning to accumulate in the kernel.
- Stress is not as severe at R3 as at R1; however, yield reduction can occur due to a reduction in the number of kernels that ultimately develop and to the final size and weight of the kernels.
- Very little root growth occurs after R3.
Scouting
Disease pressure throughout the county continues to be very low. At this stage of growth, with little to no disease pressure, and new crop corn under $5 can we justify at least $25 per acre for a fungicide application?
Soybeans
Growth & Development
Like corn, soybean development continues to vary throughout the county. Beans are looking much better than they were a few weeks ago. Last week I highlighted the R4 (Full Pod) growth stage. R5 (Beginning Seed) is the next stage, occurring approximately 10 days after R4.
