Each year I ride by some fields that have yellow peanuts. Sometimes there is a clear pattern with an equipment issue. Other times the cause of the yellow peanuts is less clear. The following slide lists some of the reasons why you may have yellow peanuts due to an inoculation failure. There is more detail in 2025 Peanut Information about this issue and the cost to correct a nitrogen deficiency.

Causes of Inoculation Failure

• Old product
• Mishandled product
• Chlorinated water
• Sitting in tank too long after mixing
• Shallow planting
• Other products in tank
• Caving of soil after seed drop before spray enter furrow
• Orifice stopped up
