Use Not every yield-boosting agronomic practice should be used in all situations. Growers need to evaluate the economic viability of practices like foliar fungicide applications to achieve the most economic return on investment. Pioneer field agronomists are available to answer these important, time-sensitive questions.
This week’s briefs cover rapid growth syndrome, hail damage in corn and soybean R3 fungicide applications.

Rapid Growth Syndrome in Corn
Rapid growth syndrome occurs when cool weather slows corn growth before higher temperatures spur rapid plant growth. When this happens, leaves fail to unfurl properly and the whorl becomes tightly wrapped. Twisting inside the whorl causes the leaves to yellow but just give it time. Leaves will green up as they unfurl, with little or no yield impact…Hear more
Evaluating Hail Damage to Cornfields
Determining the amount of leaf loss is critical after a hailstorm. Leaf loss will affect photosynthesis, and therefore yield potential, depending on the growth stage. Hail can also damage stalk quality and strength. Evaluate how deeply stalk bruising goes and whether necrosis has occurred…Hear more
Soybean Fungicide Timing
Soybean fungicides are normally applied around the R3 growth stage. However, it’s better to be slightly early rather than late when approaching your R3 application. In field trials, applying fungicide by the R3 growth stage generally provides a 2 to 5 bu/A yield advantage…Hear more
