Comparing mosquito communities of various patch-matrix landscape combinations in central Missouri, with implications for developing models to forecast abundances of important mosquito taxa
(University of Missouri--Columbia, 2010)
-matrix landscape combinations common in five central Missouri counties; 2) evaluate the temporal occurrence of these mosquito taxa; 3) assess relationships between regional weather factors and the occurrence and abundance of the mosquito fauna; and 4) categorize...
The effect of environment on seed composition of tofu and natto soybean cultivars
(University of Missouri--Columbia, 2006)
Composition of soybean seeds is important to manufacturers of tofu and natto food products. The effect of environment on seed composition of tofu and natto soybean cultivars was measured in Missouri in 2004 and 2005. The environment was altered...

(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...
A preliminary list of the rusts of Boone County
(University of Missouri--Columbia, 1913)
of the state. Since that date a considerable number of specimens has been collected, largely from this region, and placed in the herbarium of the University. The collection contains a total of four hundred and forty-three specimens. Most of these were collected...
Herbicide resistant weeds in Missouri : sources and solutions
(University of Missouri--Columbia, 2019)
Herbicide resistant weeds continue to invade new territories each year. Two studies were designed to identify both the spread and the current status of herbicide resistant weeds in Missouri. In 2016 and 2017, 98 separate commercially available bird...
Comparing the diversity, geographic distribution, and intraspecific variation of subterranean termites (Reticulitermes: Isoptera: Rhinotermitidae) occuring in woodlands and urban environments of Missouri using morphology and 16s mtDNA
(University of Missouri--Columbia, 2007)
. 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...
Genetic architecture and marker-assisted breeding for salt tolerance in soybean
(University of Missouri--Columbia, 2018)
Salinity is one of the major abiotic stresses that inhibits plant growth and causes seed yield loss in soybean. Although a major gene for salt tolerance on chromosome (Chr.) 3 was mapped, cloned and characterized, it does ...
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 ...
Horticultural crop response to synthetic auxins
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Rising adoption of dicamba-tolerant soybeans increases the potential exposure of grapes to dicamba, where off-target injury may occur via particle or vapor drift. In 2017...
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...
Plasticity of soybean (Glycine max (l.) Merrill) root system development under mild water deficit
(University of Missouri--Columbia, 2008)
soybean genotypes selected from both domestic and Plant Introduction lines were studied. The results showed substantial genetic diversity in the capacity for increased lateral root development (number and total length of roots produced...
Sulfur metabolism in Glycine max [L.] Merr : characterization of serine acetyletransferase and O-acetylserine (thiol) lyase
(University of Missouri--Columbia, 2006)
Soybean (Glycine max [L.] Merr) is considered an excellent protein source for both humans and livestock. Further improvement of quantity and quality of soybean protein is vital for maintaining the utility of this versatile ...
Agronomic and pest interactions in no-till corn and soybean wih fall versus spring herbicide applications
(University of Missouri--Columbia, 2006)
compared fall herbicide applications to early spring applications. Therefore, field experiments were conducted in both no-till corn and soybean fields from 2004 through 2006 in central, northwest, and northeast Missouri. Herbicide applications were made...
Investigations of the forage nutritive value of common weeds encountered in Missouri pastures and their relationships with soil fertility
(University of Missouri--Columbia, 2019)
During the 2015, 2016, and 2017 growing seasons, a survey of 63 pastures in Missouri was conducted to determine the effects of selected soil and forage parameters on the density of common annual, biennial, and perennial weed species. Permanent...
The sublethal effects of ecdysone agonists on the attractiveness, responsiveness, fertility and fecundity of oriental fruit moth, a comparative examination with codling moth on larval feeding damage
(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 ...
