Adam R. Wronski, Jarrad R. Prasifka, Michael S. Grove, Brady D. Koehler, Christopher G. Misar, William Underwood, Brent S. Hulke Abstract: The banded sunflower moth is one of the most pervasive insect pests of sunflower (Helianthus annuus L.) in North America, in large part due to its ability to overwinter in cold climates. The goal […]
Michael G. DeGreef, Jarrad R. Prasifka, Brady D. Koehler, Brent S. Hulke Abstract: Sunflower (Helianthus annuus L.), as a native crop, has numerous insect pests that cause economic damage to producers in the United States. The red sunflower seed weevil is a notable seed‐infesting insect pest throughout the U.S. sunflower growing region that is controlled
Streten Terzic, Marie-Claude Boniface, Laura Marek, Daniel Alvarez, Karin Baumann, Vera Gavrilova, Maria Joita-Pacureanu, Mulpuri Sujatha, Daniela Valcova, Leonardo Velasco, Brent S Hulke, Siniša Jocic, Nicholas Langlade, Stephane Munos, Loren Rieseberg, Gerald Seiler, Felicity Vear. Abstract: Modern breeding of sunflower (Helianthus annuus L.), which started 100 years ago, increased the number and the diversity of cultivated

Jarrad R. Prasifka, and Brent S. Hulke Abstract: Extracts from capitate glandular trichomes (CGT) of wild and cultivated sunflowers, Helianthus spp., have repellent or toxic effects on sunflower specialists and generalist herbivores less closely associated with sunflower. Though CGT have been primarily examined for their potential to provide partial resistance to the sunflower moth, Homoeosoma electellum Hulst
Russell Gesch, Brent Hulke, James Anderson Abstract: In the northern Great Plains and upper Midwestern U.S., incorporation of winter-hardy crops and cover crops as components of integrated weed management systems is gaining popularity as an approach for managing the spread of herbicide resistance. However, to develop new rotational cropping systems suitable to these regions there
Reinert, S., Qing-Ming Gao, Ferguson, B., Zoe M. Portlas, Jarrad R. Prasifka, Brent S. Hulke. Abstract: Seed size is an important quality component in marketing commercial sunflower (Helianthus annuus L.), particularly for the in-shell confectionery market, where long and broad seed types are preferred as a directly consumed snack food globally. Floret size is also important
Stephan Reinert, David Van Tassel, Brandon Schaultman, Nolan Kane, Brent Hulke Abstract: Silphium spp. have garnered interest in Europe as a bioenergy crop and in North America as a perennial oilseed crop. However, very little has been done at this early stage of domestication to characterize wild collections for many key characteristics, including important oilseed
Brady D. Koehler, Thomas J. Gulya, Brent S. Hulke Abstract: Necrotropic pathogens such as Sclerotinia sclerotiorum (Lib.) de Bary (causing Sclerotinia head and stalk rots) and Diaporthe spp. (causing Phomopsis stem cankers) have resulted in yield loss for the sunflower (Helianthus annuus L.) industry. The combination of durable disease resistance and high yield potential is needed for increasing crop productivity
Brian C. Smart, Brady D. Koehler, Christopher G. Misar, Thomas J. Gulya, Brent S. Hulke Abstract: Sclerotinia diseases and Phomopsis stem canker, among the most serious diseases threatening the success of sunflower (Helianthus annuus L.) production across the world, have been of increasing concern in recent history, and there is a need for additional inbred lines
Kennedy L. Money, Brady D. Koehler, Christopher G. Misar, Michael Grove, William Underwood, Brent S. Hulke Abstract: While Sclerotinia head and basal stalk rot and downy mildew have long caused problems for the sunflower (Helianthus annuus L.) production industry, Phomopsis stem canker is a disease that is a growing issue in the United States.
