Regional strengths

Full-RM hybrids fit the long Mid-Atlantic South season; gray leaf spot tolerance is increasingly important here as humidity supports persistent disease pressure. Pioneer maintains an active hybrid lineup tested in Virginia Tech and Maryland extension trials.

Regional weaknesses

Southern rust pressure can be severe in wet years on the Coastal Plain — verify the specific hybrid's southern rust rating before planting in eastern Maryland, Delaware, or eastern Virginia. Sandy Coastal Plain soils require higher seeding rates and irrigation to express full-RM yield potential.

Recommended for

  • Piedmont fields with adequate drainage
  • irrigated Coastal Plain acres

Not recommended for

  • dryland sandy soils with low water-holding capacity
  • shallow Valley bottoms
Seeding rate
30,000–34,000 seeds/acre dryland; 34,000–38,000 irrigated
Best soil types
Piedmont clay loam, Coastal Plain sandy loam (irrigated)
