Objectives:
I. Develop broccoli varieties adapted to western Oregon with suitable quality, high yields, and disease resistance. Specific traits include:
a. Early to midseason maturity
b. Concentrated yield potential
c. Downy mildew resistance
d. Exerted heads with large openly branched heads with heavy, clean stem for easy trimming and separation...
Planting date/cultivar evaluation: Thirty-six sweet corn cultivars were evaluated for resistance to natural infection by common smut (Table 1). Plots were seeded to 30,800 plants/acre on May 16 and Jun 23 on the Hermiston Agricultural Research and Extension Center on Adkins fine sandy loam (pH 6.7, 0.9% organic matter). The...
1. Rotbusters Field Survey.
Kokanee and Basin were the only varieties sampled in 2005. There was a significant relationship between radicle rot severity and gross yield for Kokanee but not for Basin.
In previous years, we have shown that for Jubilee, approximately 3 tons of gross yield are...
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...
Summary
Irrigation effects on root rot and yield
Reducing irrigation during the first 6 weeks after planting reduced root rot of sweet corn at midseason and at harvest, consistent with findings of the past two years.
Reducing the early season irrigation level increased yield of Jubilee by 20%...
Tomato [Lycopersicon esculentum Mill.] plants are chilling sensitive and do not
naturally accumulate glycinebetaine (GB), a metabolite that functions as a stress
protectant in plants. While GB can increase tolerance of tomato plants to salt and
drought stresses, its effect on chilling tolerance has not been examined. To evaluate
whether...
Cancellation of the registration of an effective bean mold fungicide, Ronilan, is slated to occur at the end of growing season in 2005. Finding equivalent alternatives by 2006 for use in snap bean is critical. The goal of the project is to continue evaluations of alternative fungicides for their effectiveness...
Objectives:
1. Breed Bush Blue Lake green bean varieties with high economic yield and improved plant architecture.
2. Improve pod characteristics including straightness, color, smoothness, texture, flavor and quality retention, and combine with delayed seed size development.
3. Incorporate white mold resistance and improve root rot tolerance.
4. Develop a...
The objectives of this project were to evaluate the efficacy of common row crop herbicides for control of puncturevine, and determine the effect of post harvest weed management strategies on hairy nightshade seed development.
Part 1: Bean mold project: What is an effective alternative to Ronilan for control of gray and white mold in snap beans when mold pressure is severe? When can we use a less expensive single fungicide application without putting the bean crop at significant risk?
Part 2: 12 Spot Beetle...
Weed management is a continual challenge to Oregon table beet growers. Research over the last several years has documented that s-metolachlor (Dual Magnum) will substantially improve weed control and crop yields when applied alone or in concert with other registered herbicides such as Roneet and Pyramin, with the potential to...
