Agronomic Updates
BETWEEN THE ROWS
WYFFELS TECHNICAL BULLETINS
Emerging Corn
Early planting and unruly weather can mean varied corn emergence. Wyffels Agronomic Marketing Manager Tom Newman provides management tips.
Scouting For Black Cutworms
Unseasonably warm weather and lack of freezing temperatures means black cutworm captures are already high. Tom Newman provides tips to deal with the pests.
Key Agronomic Practices Impacting Grower Success
Several management decisions can have a large impact on overall crop performance. Growers are advised to concentrate on key agronomic factors impacting yield first.
Black Cutworm and True Armyworm 2012 Update
This Between the Rows provides an update on the growth and development of black cutworm and true armyworm, what can be done to minimize potential damage, and takes a look at available rescue treatments.
Effective Weed and Pest Control
Unseasonably warm temperatures mean weeds and bugs are making an impact early. Wyffels Product Development Manager Brent Tharp provides tips on effective weed and pest control.
The Risk and Reward of Planting Very Early
Unpredictable weather holds the trump card for gaining yield when planting earlier than usual. A critical step for top performance is establishing a high population of uniform, fast-emerging seedlings. Weather risk can cause this critical step to influence the rest of the growing season and final performance.
Benefits and Risks of Planting Early and Optimum Dates
Wyffels Product Development Manager Bob Jackson explains benefits and risks of planting very early, optimum planting dates and replant.
Western Corn Rootworm Resistance and Control Concerns
Corn Rootworm pressure and the resulting control concerns are more prevalent than experienced in years. This Between the Rows provides perspective to consider for managing CRW going forward.
Starting With the Right Plant Population
Growers can impact final yields by starting with the right population for specific hybrids, field productivity, soil type, and yield goal. This Between the Rows highlights the importance of starting with the right planting population to ensure target population is achieved.
Heat and Drought Stress Impact on Corn Performance
Timing of heat and drought stress and its impact on final crop performance. Management factors that can help mitigate the potential impact of stress on the corn crop.
Root Lodging from Summer Storms
Growth stages that are most vulnerable to root lodging or green snap as a result of summer thunderstorms that include heavy rain and high winds. And, how growth stage affects the plant's ability to recover.
Black Cutworm and True Armyworm
Growth and development of these sporadic pests, what can be done to minimize potential damage, and a look at available rescue treatments.
Frost and Freeze Damage to Corn
Influences on the amount of damage that occurs and assessing the true extent of plant damage.
What is Green Snap?
Where this weather-related phenomenon primarily occurs, factors that influence the susceptibility of corn to green snap, and how to manage the risk of green snap.
Delaying Planting Considerations
Research on the ability of corn hybrids to adapt to delayed planting and the effects of delayed planting on corn development and yield potential.
Goss's Bacterial Wilt Hybrid Rating Update
Goss's bacterial wilt has received some recognition this past growing season in areas where we don't traditionally see it. Where Goss's wilt was confirmed the previous year, growers may wish to consider Goss's wilt tolerance ratings for specific hybrids when making their seed decisions.
Wyffels Study Investigates Yield Response to Fungicide Application
Discusses proprietary study results, understanding return on investment for fungicide applications, secondary benefits, management considerations.

Hybrid Observations and Yield Estimates: Kernels—It's More than Numbers
Current crop situation, factors impacting photosynthesis, impact of temperature, yield estimates on a whole field basis.
Stalk Rot Diseases of Corn
The presence of stalk rot can be responsible for significant yield loss when the disease causes premature death resulting in poor ear fill or light test weights. Reviews causal organisms and agronomic management considerations.
Managing Corn in a Sustained Wet Environment
The impact from weeks of saturated soils during fast growth (knee-high to tasseling) can be significant. Discusses the effects and potential management options.
Goss's Bacterial Wilt
Over the past few years, Goss's bacterial wilt has spread across several Midwestern states. Identifies causes, symptoms, and actions to reduce the likelihood of infection next season.
Gray Leaf Spot
High levels of rainfall early in the season can increase the presence of leaf diseases. Discusses scouting and management practices to consider.
