Vegetable processing

A number of growers and agricultural professionals have asked me whether we are seeing resistance to mold in snap beans to our currently registered fungicides. The short answer is, not to my knowledge. In a normal year, the primarily threat to snap beans is white mold (Sclerotinia sclerotiorum). When we have a cool, wet spring, we see both white mold and gray mold (Botrytis cinerea). Gray mold is a game changer. Gray mold control requires a tank mix, early timing, and a two spray program.

The general objective of the processing component of this research is to support the vegetable processing industry in the Willamette Valley by evaluating green beans developed in Jim Myers' bredding program in OSU's Horticulture Department.

Objectives:

1. Maintain, evaluate, and refine a regional pest monitoring network for selected Lepidopteran pests of broccoli and cauliflower, and other crops.
2. Develop new strategies for detecting aphid outbreaks.
3. Evaluate whether less aggressive spray programs are effective during periods of low insect pressure.
4. Compare the effectiveness of aphid and looper pesticides at various levels of insect pressure.

Objectives: To evaluate yield, uniformity, plant characteristics, and ear characteristics in the field, and processed quality of new varietal introductions of supersweet (sh2) corn.

Objectives:

• To test supersweet (sh2) corn varieties for production characteristics and processed quality.
• To determine the relation of maturity stage, yield, and quality for selected varieties.

Objectives:
To determine the production and processing potential of new introductions of supersweet corn.

Objectives:
To determine the production and processing potential of new introductions of supersweet corn.

Objectives
Peas:

• Evaluate weed control efficacy and crop tolerance of Cobra on processing peas.
• Evaluate combinations of MCPA amine, Basagran, Poast and crop-oil for weed control efficacy and crop tolerance in processing peas.
• Investigate the feasibility of field sampling to determine weed densities and weed species of sampled fields.
• Follow development of black and hairy nightshade from emergence through crop harvest to determine potential for crop contamination.

Snap Beans:

Objectives:

• To determine relationships among maturity time, percent moisture, yield, flavor, texture, color, and appearance in SE varieties.
• To determine the production and processing potential of new introductions of sweet corn.

 Objectives:
Determine yield and quality characteristics of sweet corn cultivars which may be appropriate for climate and cultural practices in the Columbia basin.
