New Tools for Managing Erysiphe necator: Rapid Sampling Approaches and an Exploration of Grower Opinions and Perspectives towards Collective Action and Information Transfer

Creator:: Lowder, Sarah R.
Abstract:: The scale of pest and disease dispersal is often larger than the scale of individual farms. Therefore, an individual grower’s response to pests and diseases can affect and is affected by their surrounding growing region. Individual growers are also not isolated, and engage in various forms of information gathering, sharing,...

A comparison of soil microfungi in forest stands of Red Alder, Conifer, and Alder-Conifer mixtures

Creator:: Wicklow-Howard, Marcia C. (Marcia Cope) 1943-
Abstract:: The species composition of soil microfungal populations in-adjacent stands of red alder, conifers, and mixed alder conifer correlated strongly with the dominant vascular vegetation. A total of 92 species were isolated: 55 from the alder stand; 45 from the conifers; and 46 from the mixed alder-conifer, with few species (16,...

Overwintering of Erysiphe necator and Inoculum Monitoring for Decision Aids

Creator:: Thiessen, Lindsey D.
Abstract:: Grape powdery mildew (Erysiphe necator) causes economic damages to grape worldwide due to the cost of management and injury to berries. Each region where European grapevine (Vitis vinifera) is grown experiences a unique epidemic, and disease prediction models that are based on empirical correlations of weather data to disease fail...

Rhizosphere microfloras associated with mycorrhizae of Douglas-fir and red alder

Creator:: Neal, John Lloyd
Abstract:: The mycorrhizal rootlets of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco.) and red alder (Alnus rubra Bong.) were extensively investigated. A jet-black mycorrhiza was found to be dominant on Douglas-fir rootlets. The fungal symbiont was identified as Cenococcum graniforme (Sow.) Ferd. and Winge. Two forms of mycorrhizae predominated on root systems of...

Effect of Endothal and certain other selective herbicides on microbial activity in six different soils

Creator:: Au, Frederick Hung Fo
Abstract:: The effect of Endothal (3, 6-endoxyhexahydrophthalic acid), sodium pentachlorophenate (Na-PCP) and TD-47 (di-N, N-dimethylcocoamine salt of Endothal) on the microbial populations, ammonification, nitrification and respiration in six different soils was investigated. It was found that Endothal at 20 and 200 ppm had no adverse effect on the microbial population, ammonification,...

Interaction between dipyridylium herbicides and microbes in soil

Creator:: Tu, Chin-Ming, 1932-
Abstract:: The herbicides Diquat (1, 1'-ethylene-2, 2'-dipyridylium dibromide), Paraquat (1, 1'-dimethyl-4, 4'-dipyridylium dichloride), and Gramoxone (1, 1'-dimethyl-4, 4'-dipyridylium dimethyl sulphate), and the spreader X-77, a mixture of alkylaryl-polyethylene glycol, free fatty acids and isopropanol, were tested by several soil microbial methods in an attempt to find out if concentrations of these...

Total Kinetic Energy Release in the Fast Neutron Induced Fission of 237Np

Creator:: Pica, Ashley
Abstract:: The total kinetic energy (TKE) in the fast neutron induced fission of 237Np was measured for neutron energies from En = 2.6 – 45.7 MeV at the LANSCE- WNR facility. The postTKE release decreases non-linearly with increasing incident neutron energy and can be represented as TKE(MeV) = (169.365 ± 1.551)...

Dependent evidence in reasoning with uncertainty

Creator:: Ling, Xiaoning
Abstract:: The problem of handling dependent evidence is an important practical issue for applications of reasoning with uncertainty in artificial intelligence. The existing solutions to the problem are not satisfactory because of their ad hoc nature, complexities, or limitations. In this dissertation, we develop a general framework that can be used...

F-tests in partially balanced and unbalanced mixed linear models

Creator:: Utlaut, Theresa L.
Abstract:: This dissertation considers two approaches for testing hypotheses in unbalanced mixed linear models. The first approach is to construct a design with some type of structure or "partial" balance, so that some of the optimal properties of a completely balanced design hold. It is shown that for a particular type...
