Objectives:
In 1991, we noted that symphylan density was less under spring-planted Micah barley residue than other cereals, conventional tillage, and soil with no cereal residue. The objectives of this trial were to further evaluate the impact of several plant species on the density of symphylans in snap bean systems

Objective 1: Evaluation of commercial sweet corn varieties and inbred germplasm in small plots for susceptibility to seed rot/damping-off as well as root, stalk, and crown rot.

Objective 2: Evaluation of microbial and chemical treatments for suppression of sweet corn seed rot/damping-off, root rot, and crown rot.

Objective 3: Cooperate with other sweet corn projects (cultivar screenings, irrigation studies, etc.) within and outside of OSU programs.

Twelve lines of cauliflower were direct-seeded on July 13, 1977, with the purpose of overwintering several European cultivars for spring harvest. In addition some other lines were included for comparison. Lines or varieties were as follows: M1, M2, M3, and M4 from Moran Seed Co., Snow Crown from Harris Seed Co., Armado April, Armado May, Armado Quick, Armado Tardo, June, and Markanta Walcherin from Elsoms Seeds Ltd., and Pinnacle from Asmer Seed Co. Plot size was 24 row feet containing about 25 plants.

The resistance to white mold obtained so far in snap beans has been derived from NY 6020, which provides partial physiological resistance. Under light disease pressure, plants will show few if any symptoms, while under heavy pressure, the plants may show a moderate level of infection (whereas susceptible BBL types will be 100% molded). Cultivars with this form of resistance would not need any supplemental control with fungicides, whereas under heavy pressure, fungicides might be required, but at a reduced frequency or quantity. The objective of this study was to determine whether OR6771 would benefit from an integrated mold control approach that included fungicides typically used in snap production, Topsin M and Rovral tankmixed.

For the past several years a "stalk rot" disease has been afflicting commercial sweet corn fields grown in the Willamette Valley. The disease seems to have a pathogenic basis, but the exact causal agent is unknown.
Eighteen hybrids with se or su endosperm were evaluated for resistance to root/crown rot. Ears were also evaluated for processing quality.

Objectives: Characterize su and se sweet corn hybrids for reaction to root/crown rot.

Cooperator: M. Powelson, Botany and Plant Pathology

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

  • Weed control was less and crop injury more with the split application (PES/POST) of Outlook than the full rate of Outlook applied preemergence.
  • Weed control was exceptional with Outlook (dimethenamid) applied PES at 0.054 lbs ai/A but crop injury was unacceptable.
  • Outlook applied postemergence to 2-leaf beets caused some crop growth reduction but did not reduce yield or grade. This treatment did not improve weed control ratings compared to the growers treatment.
February 1, 1987

Shallots may be grown as an overwinter or spring-planted crop in the Willamette Valley. Major cultural problems in this crop include weed and disease control, effect of planting dates on yield, maturity, and degree of bolting, and the effects of size of, planting stock and planting density on yield and bulb size at harvest. This study was designed to investigate the effects of three planting densities and two bulb sizes on the total yield and mean bulb weight at harvest and on the number of bulbs produced per bulb planted.

These results are consistent with research in 1996-98: imazamox could be used postemergence in snap beans at 0.024 lbs ai/A with little risk of yield reduction. Imazamox adequately controls pigweed, nightshade, and many grass weeds at this timing and rate. Future
research should focus on lower use rates, earlier timings, and interactions with Basagran, surfactants, and insecticides on both crop injury and weed control.

Oregon is the second largest producer of processed green beans, and cultivars are needed that are adapted to western Oregon. The types that have traditionally been used are the bush blue lake (BBL) green beans with high yields, excellent processing quality. On the other hand, then need improvement in plant architecture, disease resistance (especially to white mold), and are genetically isolated from other green beans. The primary objective of the OSU green bean breeding program is to develop high yielding and high quality BBL green beans with high levels of white mold resistance. In 2015, a yield and processing trial of 18 advanced lines was conducted. An additional commercial trial with 27 entries was also grown and evaluated. Seven advanced lines are undergoing intense scrutiny for release as the first partially white mold resistant lines commercially available.

The purpose of this guide is to provide Willamette Valley growers with an introduction to the wildlife diversity of the region, a primer on habitat management, and some suggested actions that can be taken by growers to benefit native wildlife living on agricultural landscapes. Given the extensive area of the Valley used for farming, even modest actions undertaken by individual growers can accumulate into a major contribution toward regional conservation goals.

Processors need broccoli with better quality traits than what is available in cultivars developed for California and Mexico fresh markets. Farmers need to reduce labor costs of broccoli production by mechanizing harvest. Most contemporary commercially available cultivars are not suitable for either mechanical harvest or processing. The objective of the OSU broccoli breeding program is to develop broccoli varieties adapted to western Oregon with suitable quality and high yields. The program operates on a one year cycle where cuttings from the field are taken into the greenhouse in the fall where they are rooted and hand crossed and self-pollinated to produce seed for the next generation. Seed is harvested in May and June and used to plant trials for fall evaluation. In 2015, nine experimental hybrids were planted in a replicated yield trial, which also included two commercial check hybrids and a new exserted commercial hybrid from Seminis.
