become a troublesome weed. Little is known about the interference and management of Gly-R volunteer corn in corn. The objectives of this research were to: a) determine the extent of kernels remaining in fields following harvest; b) identify...

environmental conditions within different landscape configurations may help approximate a model for predicting the risk of encountering these disease vectors. Therefore, the goals of the research were to 1) describe the mosquito fauna of the various patch...

giving rise to a mature whole plant. The breadth of application for genetic engineering is limited by constraints on one or both of these factors in many plant species and individual varieties. Uncovering plant genes which are involved in important...

stable aggregates, soil moisture, total organic carbon, active carbon, potentially mineralizable nitrogen (PMN), and soil microbial community composition via a phospholipid fatty acid (PLFA) analysis were measured in 2017 and 2018 in Columbia, MO under no...

The purpose of this project is to modify the fatty acid composition in soybean seeds to improve soybean oil quality and functionality. By sequencing the FAD2-1A and FAD2-1B genes in 24 plant introductions, we identified two novel mutant alleles: one...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Sweet potato (Ipomoea batatas (L.) Lam.) is a global important food crop, that has recorded an increase in the consumption, and demand for especially organically produced...

study show that herbicide applications made in the fall that contain metsulfuron will provide approximately 50% control of this weed, but where severe infestations exist a follow-up application will be required. Tall fescue can also be detrimental...

-directed, organic herbicides may provide a viable alternative to continued tillage for weed management in soybean. CHAPTER IV. Response of Soil Biota to Long-term Organic Weed Control Practices. Abstract: Current weed management practices in organic systems...

Tallgrass prairies once occupied a large swath of central North America, but now face the combined challenges of habitat loss and fragmentation. In Missouri, where less than 1% the historical prairie remains, prairies are being reconstructed from...

Field pennycress has the potential to serve as a cover and oilseed crop. A seed oil content of 25 to 36 percent has created interest in pennycress domestication. This research evaluated management strategies for growing field pennycress. The most...

"There is an increasing emphasis on management strategies such as reduced tillage, use of cover crops, and implementation of conservation practices (i.e. terraces, no-till, and cropping systems) in Missouri cropping systems. By combining best...

Cotton (Gossypium hirsutum L.) and maize (Zea mays L.) are important economic crops that can suffer significant yield loss under drought. Cotton and maize root systems have fundamentally different architectures, in addition to cotton being a...

corn rootworm and northern corn rootworm bioassays rearing. These new formulations provide a standardized growth medium for western corn rootworm and northern corn rootworm larvae that will facilitate toxicity test comparisons conducted by different...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Soybean is influenced by temperature and light, and global warming has been shown to reduce soybean yields. In this study we tested the germination of TM-Miniature, a soybean...

the movement of glyphosate resistance through pollen within a population of common ragweed and evaluate the release of glyphosate from glyphosate-resistant and -susceptible common waterhemp. Results revealed that glyphosate-resistance could move throughout a...

in this dissertation is designed to provide a better understanding of the environmental conditions and transport mechanisms that influence dicamba volatility and off-target movement and also evaluate the spectral response and yield effects following dicamba and 2,4-D...

. In urban environments they feed upon dead wood, and therefore infest and destroy man-made wooden structures. Missouri is considered to have a moderate risk for termite infestations when compared with the states of the southeast part of the country. Despite...

two characteristics: rapid cell death at the site of inoculation and localization of the pathogen to that site. I examined a resistant Nicotiana hybrid, which does not respond with HR-mediated cell death, yet maintains resistance to Cauliflower mosaic...

challenging, especially under field conditions. Nonetheless, a better understanding of root system form and function is critical to develop strategies to breed for more stress-resilient crops for local production environments. Studies of soybean root systems...
