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...
The accessions used to create the Snap Bean Diversity Panel were 150 snap bean (Phaseolus vulgaris) cultivars and breeding lines selected from North American and European germplasm to create a population that is representative of the snap bean market class from a historical and geographical viewpoint. This panel was developed...
The accessions used to create the Snap Bean Diversity Panel (SnAP) were 378 snap bean cultivars and germplasm lines selected from North American and European germplasm. This panel supplements the 150 member Bean CAP snap bean diversity panel (SBDP) with an additional 228 snap bean accessions. The Bean CAP SBDP...
Beginning the 2008 Season… It appears that the spring weather we’ve been waiting for has finally arrived! Bud break is commencing, a week or so later than 2007 due to cold weather in most of Western Oregon. With the advent of the growing season, this edition of the OSU Wine...
Three different cover crop treatments were compared for their effects on vine growth, leaf gas exchange, yield parameters and fruit composition. The treatments were: resident plants, an insectary plant mixture and a grass cover. At veraison (August 2 1), photosynthesis rate was lowest for the vines with the grass cover...
Energy input comparisons between tillage systems; evaluation of the value of legumes as part of a cover crop mixture used in strip-till sweet corn production; evaluation of the nitrogen contribution of legume-based cover crops to organic vegetable production.
Oregon's wine grape industry uses yield targets to achieve quality in Pinot Noir vineyards, and this practice has led to increases in cost of production. A multiapproach study was conducted to investigate how vineyard target yields are set, why yield thresholds exist, and who influences decisions related to vineyard target...
Objectives of proposed research:
1. Investigate the relationship between abscisic acid (ABA) and auxins and the regulation of carbon partitioning.
2. Investigate the origin of ABA present in the fruit during ripening and attempt to modify the partitioning pattern through manipulation of endogenous ABA levels using mefluidide (ABA biosynthesis promoter)...
Crops were grown using accepted cultural practices within the limits of experimentation or trials were conducted on growers' fields, Most experiments were designed as randomized complete blocks with two to five replications. Herbicide treatments were applied uniformly with equipment ranging from precision plot sprayers to quart jars (granular applications). Unless...
Project Objectives
1. Develop and evaluate a Pilot IPM scouting program for the WSCB in snap beans
2. Determine the seasonal aggregation and movement patterns within diversified vegetable cropping systems
3. Evaluate the potential for “trap and kill” strategies as cultural control components of an IPM program for the WSCB...
