Assessment of Early Planting and Early Maturing Hybrids as Tools in Management of the Red Sunflower Seed Weevil in North and South Dakota
Principal Investigators: Jarrad Prasifka, USDA, ARS, Ryan Buetow, Mike Ostlie, Kristin Simons, North Dakota State University, and Sam Ireland, Adam Varenhorst, Patrick Wagner, South Dakota State University.
Project Objectives: This project will assess effects of early planting and early maturing hybrids to provide more current, local data that supports grower decision making on planting times and seed weevil management. Damage by red sunflower seed weevils, yield, and quality (% oil) in oilseed sunflowers will be measured to determine if farmers could plant much earlier than is common in South Dakota and North Dakota without sustaining significant yield and or quality losses. The results could allow producers to choose to plant (and harvest) earlier or use earlier maturing hybrids to avoid yield losses from red seed weevil or other time-sensitive causes (e.g., lodging, birds). The South Dakota Oilseeds Council provided $10,000 of check-off dollars to match $5,000 provided by the NSA Confection Promotion Committee towards this project.
Funded Amount: $52,000
