Day 1 - Pro Farmer Crop Tour
Eastern Route - Monday August 21
Day 1
- Begins in Columbus, Ohio.
- Ends in Noblesville, Indiana.
- Follow the Eastern route:
Leader - Brian Shrader, Pioneer Field Agronomist,
East-Central Indiana
Crop Updates - East-Central Indiana

Corn
- Early season drought conditions as well as the impact of isolated heavy rain fall events accompanied by wind and hail are contributing factor to crop development and potential yields.
- Disease pressure, specifically GLS and NCLB remains lower then expected at this time.
- Tar spot has moved south and east more aggressively than in prior seasons.
Soybeans
- Soybean growth has been slower due to both weather impact as well as wildfire smoke and haze.
- Disease levels remain low in soybean, especially foliar disease such as frogeye leaf spot.
- SDS remains surprisingly low in most areas of state.
Weather Extremes
- Early drought stress appears to have had some impact on overall yield in some areas of Indiana.
- Isolated areas with severe hail and rain damage during early development.
Disease Pressure Levels
- While moisture and temperature have been adequate GLS and NCLB remain relatively low.
- Tar spot levels are increasing and confirmation of disease has been made further south and east in the state earlier then previous years at this stage of crop development.
- Soybean disease pressure continues to be low, isolated areas of frogeye leaf spot are being reported and SDS remains at low levels.
Western Route - Monday August 21
Day 1
- Begins in Sioux Falls, South Dakota.
- Ends in Grand Island, Nebraska.
- Follow the Western route:
Leader - Calvin Rupe, Pioneer Field Agronomist,
South-Central Nebraska
- Moisture stress and irrigation management are going to prove to be a limiting factor in the 2023 crop in central Nebraska. We experienced some timely rains at the end of June and first part of July, but the end of July and early August have made for some struggles. Yield potential will be directly proportional to the depth of the pivot tracks.
- Drought is going to continue to be a factor on how well our soybean crop finishes out. We will need to be watering well into September on soybeans and August is going to be mission critical.

Corn
- Very minimal disease pressure this year. Northern corn leaf blight seems to be the most readily observed disease especially hybrid specific. Lots of fungicide applications were made for the respiration and water use efficiency benefits, especially with lows being in the 80’s at the tail end of July shortly after pollination.
- We have seen a significant amount of HPPD flashing in corn this year due to the drier conditions during pre-emerge applications across several acres.
- With our current state of drought, there has been a higher call load of ammonia burn on corn, especially under no-till environments where high-speed applicators were used at an angle. Just as so with coulter machines less than 6” from the furrow.
- Pollination window was very good prior to the heat. We did have some pockets with wind damage due to some July storms which has posed the conversation about the potential for some abnormal ear development.
Soybeans
- Pre-watering and irrigation over pre-plant herbicide applications have proven to be the best management practice for irrigated soybeans in 2023 to date. We achieved activation of herbicides and mitigated our risk of injury at emergence by doing so.
- We have observed some carryover herbicide in soil samples from late replanted acres of corn in June last year due to weather events. This has caused some concerns when we have replanted soybeans. Tank contamination still seems to prevail as the predominant issue.
- Herbicide applications made after planting consisting of Group 14 and 15 herbicides have been an issue with our dry soil conditions, especially when watered in to try and achieve emergence. Make sure to apply anything with a PPO 10-14 days prior to planting.
- Enlist E3® soybeans are showing very good potential in terms of nodes, pod and flower clusters compared to Roundup Ready 2 Xtend® (RR2X) varieties in our geography. We cannot continue to abuse a good technology such as dicamba past June 30th.
