Beets

Despite the availability of several herbicides in table beets, weed control is still problematic. UpBeet (triflusulfuron; DuPont) was recently labeled, but the labeled timings and rate are inadequate for optimum weed control, particularly for lambsquarters. An experiment was placed at the OSU Vegetable Research Farm to determine the tolerance of 2-leaf table beets to UpBeet when applied at double the currently labeled rate of 0.5 oz/A, and to beets at the cotyledon stage at 0.5 oz/A.

Objective:

1. determine the potential of using Dual Magnum herbicide for weed control in table beets.
2. evaluate the potential of using Upbeet, Betanex, and Betamix as sequential micro-rate applications.

Objectives:

• To determine the effects of differential quantities of irrigation water on growth and yield of table beets.
• To determine the relationship of nitrogen fertilizer rates to yield and size distribution of table beet roots.
• To determine N concentrations in table beet leaves as affected by irrigation and N fertilizer rates.

Objectives:

1. Determine which species of cutworms are pests in table beets.
2. Determine if pheromone trap catches can be used to predict cutworm problems and time control measures.
3. Evaluate the use of sweep net sampling, egg sampling, soil surface sampling and early leaf feediyy to predict root damage and time control measures.

OBJECTIVE: To evaluate the efficacy of registered and unregistered chemical controls of Downy Mildew of Table Beets (Peronospora schachtii) and other foliar diseases of beets.

Objectives:

1. Continue investigation of pheromone traps to predict cutworm infestations.
2. Test efficacy of registered insecticides for control of the black cutworm, emphasis on detection and timing.
3. Test insecticide bait for detection and control of black cutworm.
4. Determine when black cutworm gets into to table beets, overwintering and migration.

Objectives:

1. Evaluate the role of planting date on cutworm colonization.
2. Evaluate the role of plant height/age in cutworm colonization.
3. Determine the best time to apply insecticides for the black cutworm based on 1 and 2.
