Influence of herbicides application on weed and tall fescue management and grazing distribution in Missouri pastures
(University of Missouri--Columbia, 2012)
One weed that is of concern in Missouri pastures that can be detrimental is Northern dewberry (Rubus flagellaris Willd.). This weed can be detrimental due its production of spines which can injure grazing animals and also humans. Results from our...
Integrating cover crops into crop rotations in upstate Missouri
(University of Missouri--Columbia, 2018)
"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...
Interactions between cover crops, herbicides and weeds in soybean production systems
(University of Missouri--Columbia, 2018)
. An identical field experiment was conducted in 2016 in Arkansas, Indiana, Missouri and Wisconsin and repeated in Arkansas, Indiana, Mississippi and Missouri in 2017 to evaluate the most effective herbicide treatments for spring termination of regionally...
Recommendations for tree establishment in tall fescue-based silvopasture
(University of Missouri--Columbia, 2008)
Silvopasture offers Midwest landowners the opportunity to plant trees in their pastures without significant loss of forage production. However, much of the pasture in the Midwest is dominated by tall fescue (Schedonorus ...
Glyphosate resistance : pollen movement within a common ragweed (Ambrosia artemisiifolia L.) population and herbicide release from common waterhemp (Amaranthus rudis sauer) plants
(University of Missouri--Columbia, 2011)
Common ragweed and Common waterhemp are native, summer annual weeds distributed widely throughout the United States. Both weed species have developed resistance to the broad-spectrum herbicide glyphosate. Research was ...
Overseeding annual ryegrass and cereal rye into soybean for winter forage and as a cover crop for weed control and soil conservation
(University of Missouri--Columbia, 2005)
studied how to integrate these forages in a soybean [Glycine max (L.) Merrill]-winter pasture-corn (Zea mays L.) rotation. An experiment was conducted where each of these forage species was overseeded at different stages of soybean development, and corn...
Grapevine trunk disease in Missouri vineyards : prevalence and causality of fungal species by cultivar
(University of Missouri--Columbia, 2020)
's Postulates were evaluated in a greenhouse by inoculating shoots of Vitis interspecific hybrid cultivar Vignoles, the most widely planted white grape cultivar in Missouri. Shoots were inoculated and placed in a greenhouse for ten days. All shoots inoculated...
Resource extraction, resistance, and religion in Nicaragua

mining, especially related to economic threats and grievances tied to environmental and agricultural concerns, it will likely continue its resistance movement until it sees policy changes that halt or overturn mining concessions in the community. However...
Grasshopper and bee communities on Missouri prairies : comparing reconstructions and remnants
(University of Missouri--Columbia, 2018)
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...
Impact of alternate host phenology amd alternate hose-transgenic corn interactions on the Western corn rootworm (Coleoptera: Chrysomelidae)
(University of Missouri--Columbia, 2006)
With the increasing adoption of transgenic maize with resistance to rootworms, combined with glyphosate tolerance, as a control tactic for western corn rootworm, Diabrotica virgifera virgifera LeConte, an understanding of ...
The influence of fusarium species on sweet potato plant performance, root yield and quality
(University of Missouri--Columbia, 2018)
[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...
Evaluating and improving corn nitrogen fertilizer recommendation tools across the U.S. Midwest
(University of Missouri--Columbia, 2018)
Determining which corn (Zea mays L.) nitrogen (N) recommendation tools best predict the economically optimal N rate (EONR) would be valuable for maximizing profits and minimizing environmental consequences. The objectives ...
The semiaquatic heteroptera (Gerromorpha) of Thailand : faunistics, biogeography and phylogeography
(University of Missouri--Columbia, 2008)
Semiaquatic heteropterans (Gerromorpha) were collected from mountain streams and waterfalls and lowland ponds adjacent to the mountains were collected from 2002 to 2006. One hundred fifty-eight species representing 31 ...
Top-soil root architecture characteristics of obsolete and modern soybean cultivars and shoot and seed nutrient contents
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI--COLUMBIA AT REQUEST OF AUTHOR.] Soybean (Glycine max Merr.) is one of the most important cash crops worldwide. It is widely used to produce oil and protein for food and animal feed. Soybean grain...
Biodiversity of ants (Hymenoptera: Formicidae) in restored grasslands of different ages
(University of Missouri--Columbia, 2006)
sampling) on four different ages (0, 3, 7-8, 14-16 yrs) of grassland in east-central Missouri. Efficacy of sampling methods was also examined. A total of 18,743 ants were collected, representing 28 species in 16 genera. Ants were most abundant in older ages...

(University of Missouri--Columbia, 2006)
The ecdysone agonists methoxyfenozide and tebufenozide are designed to affect the larval stage of Lepidopteran pests. Recent studies have reported sublethal effects on the adults of several tortricid apple tree pests exposed ...
Novel approaches in macroinvertebrate biomonitoring
