Vegetable production

Objectives:
Sweet corn and supersweet corn varieties were evaluated for agronomic and processing performance.

Objectives:

To determine the production and processing potential of new introductions of sweet corn.

Objectives: 

The objective of this research was to collect samples of carrot roots from soil in which ethoprop had been applied. Samples from the treated plot were to be analyzed for ethoprop residues and compared to untreated samples from the same field. The results were to be used to establish a residue tolerance level for carrots. The data collected from this field study was to become part of a petition to be submitted to EPA by IR-4 requesting that a national residue tolerance be established for ethoprop (MOCAP) in carrots.

Objectives:

Objectives:

Evaluate Surpass (acetochlor), Frontier (dimethenamid), Tough (pyridate), and Accent (nicosulfuron), for weed control and crop tolerance, and develop appropriate weed control programs to minimize impact of atrazine tolerant weeds and proso millet.

Determine tolerance of sweet corn to propane flaming with emphasis on early postemergence applications.

Determine impact of cover crop residues on weed emergence, herbicide efficacy, and sweet corn growth in both minimum tillage and conventional tillage systems.

Objectives:

Determine most efficient use rates of Cobra with Dual to minimize crop injury and maximize weed control.

Assess tolerance of snap beans to herbicides such as Cobra, Dual, Frontier and commonly used tank mixes.

Evaluate current and potential herbicide options for full season weed control and compatibility with cultivation.

Develop a long-term research site with a uniform distribution of white mold sclerotia in the soil.

OBJECTIVES: 1) Determine the distribution and severity of stalk rot of sweet corn in the Willamette Valley; 2) Determine which Fusarium species are most commonly associated with stalk rot; and 3) Conduct a crop history survey.
