Optimization of Agrochemical Application Technologies, Strategies and Chemical Control of Spotted-wing Drosophila, Drosophila suzukii (Matsumura), Diptera: Drosophilidae as a Model Organism and Identification of Trisiloxane and Silane Surfactants in Agricultural Spray Adjuvants and Reference Materials

Creator:: Mermer, Serhan
Abstract:: Drosophila suzukii (Diptera: Drosophilidae) is an insect of global concern that causes serious damage to soft-skinned fruits. D. suzukii is widespread in North America, South America, Europe, and Asia and is listed as an invasive pest with strict quarantine protocols governing import and export. Given the damage caused by D....

Improving nitrogen management with cover crops in organic broccoli production

Creator:: Garrett, Amy
Abstract:: Legume cover crops can serve as important sources of nitrogen (N) in sustainable agriculture and can be economically beneficial when fertilizer inputs are reduced without a yield reduction. Synchronizing N mineralization from organic materials with the needs of the subsequent crop is a challenge for organic growers. Predicting plant available...

Developmental anatomy of Phaseolus vulgaris L. as influenced by temperature

Creator:: Wivutvongvana, Manee
Abstract:: Bush snap beans (Phaseolus vulgaris L.) cvs 'G5O' (Gallatin 50) and 'OSU58' (Oregon 58) were used for anatomical and morphological studies of their responses to three levels of temperature. The plants were grown in a controlled chamber under a 16-hour photoperiod at 60°/50°, 70°/60° and 80°/70°F (day/night temperature), respectively. The...

The effects of plant population and nitrogen on sweet corn yields

Creator:: Moss, Joe Dick
Abstract:: The response of sweet corn (Zea mays L. var. rugosa cultivar Jubilee) to 12 populations and four nitrogen rates was studied in a field experiment. Populations ranged from 43, 904 to 329,800 plants/ha with nitrogen levels ranging from 0 to 224 Kg/ha. A systematic spacing design was used. Plant height,...

Effects of plant population on plant characteristics and yield of bush snap beans

Creator:: Hatch, Duane Leroy
Abstract:: 'Tendercrop' and 'OSU 949' green snap beans were grown at populations varying from 77,000 to 392,000 plants per acre with two row spacings and six square arrangements ranging from 4 x 4 to 9 x 9 inches. Maximum yield of 10.1 tons per acre (32 percent sieve size 4 and...

Recovery of Penncap-M from Foraging Honey Bees and Pollen Storage Cells

Creator:: Burgett, D. Michael and Fisher, Glenn C.
Abstract:: Foraging honey bees (Apis mellifera L.), exposed to birdsfoot trefoil (Lotus corniculatus L.) bloom treated with microencapsulated methyl parathion, continued to display pollen and midgut microcapsule contamination up to 9 days postspray. Nearly 10% of all pollen storage cells examined in combs taken from honey bee colonies exposed to the...

Monitoring soil nitrate to estimate cover crop nitrogen contribution

Creator:: Andrews, Nicholas, Sullivan, Dan M., and Pool, Kristin
Abstract:: Organic vegetable growers rely on legume cover crops as an economical source of plant-available N. This research evaluated N contributions to summer vegetable crops by cover crops (CC) residues by monitoring soil nitrate (NO3-N) concentrations during the summer crop growing season. Replicated field plots were established with three CC mixes:...

Beans, cabbage, and sugar beets in a chemically suppressed sod of Manhattan II perennial ryegrass

Creator:: Rinehold, John W.
Abstract:: Crops were planted into tilled strips in an established perennial ryegrass (Lolium perenne L. 'Manhattan II'), sod covering various portions (55%, 66%, 77%) of the row width. Italian beans (Phaseolus vulgaris L. 'Romano II') biomass and yields showed a trend among sod strips with lower yields produced in plots with...

Vine morphology and influence of shading on yield, fruit quality, and flower bud initiation in hardy kiwifruit (Actinidia arguta)

Creator:: Tiyayon, Chantalak
Abstract:: Morphology of Actinidia arguta (Sieb. et Zucc) Miq. 'Ananasnaya' vines was studied at two sites in Oregon in 1998 and one site in 1999. Three-year-old vines at site 1 and 8-year-old vines at site 2 were observed. Five types of fruiting wood were studied: spur; one-year-old from the cordon, from...

Measuring ammonia loss using field-scale and laboratory techniques

Creator:: Heinrich, Aaron and Sullivan, Dan M.
Abstract:: Following the surface application of urea to soil, there is the potential for nitrogen (N) loss from ammonia (NH3) volatilization until sufficient rain or irrigation has moved it into the soil. Many studies measuring NH3 loss have used laboratory and microplot field studies. The limitation of these techniques is that...
