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....

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...

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...

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...

On-farm inquiry and assessment of tillage and cover cropping for white mold control in snap bean production

Creator:: Harrison, Elizabeth Langham.
Abstract:: Cultural practices in snap bean production were evaluated at the Oregon State University Vegetable Research Farm Corvallis, Oregon. In addition, decision-making in snap bean production was assessed on five farms in the Coburg-Junction City-Harrisburg regions of the Willamette Valley, Oregon. A field experiment with cover crop and tillage techniques was...

Evaluation of botanical diversity in Oregon vineyards

Creator:: Schonenberger, Patrik M.
Abstract:: Three different ground cover management strategies were compared at the OSU research vineyard near Alpine, Oregon. Botanical diversity was actively increased in two diverse treatments. Another treatment was botanically uniform and contained creeping bentgrass (Agrostis stolonifera). The composition of the vineyard floor vegetation and grapevine performance as affected by the...
