brief background
Brief Background
  • Interest in processed frozen spinach
  • Spring of 2003 - 4 growers planted
  • Summer of 2003 - 4 plantings in Mason/Oceana counties - approx. 80 acres
  • Decision - not to harvest - over winter
  • Potential for expansion 2004-2006

National Spinach Conference

November 20 & 21 2003

Fayetteville, Arkansas

  • Vegetable AoE - Growing the Michigan Vegetable Industry
  • $2,000 grant - myself and three other growers attended
1st day of meetings at washington county extension office

What did we learn?

  • Spinach is good for you

- Vitamin A, Vitamin C, Iron

- Antioxidant activity

- Folic Acid & disease-prevention properties

- Age-related Macular Degeneration

- Bottom-line - eat more spinach! Why? For all the above reasons…. it’s good for you!

herbicides issues
Herbicides Issues

Nilda Burgos - Department of Crop, Soil, and Environmental Sciences at University of Arkansas

  • Need for additional herbicides critical
  • 3 registered in Arkansas

- cycloate (Ro-Neet), sethoxydim (Poast), and phenmedipham (Spin-aid)

- metolachlor (Dual) preemergence; Sec. 18, many years

- Exploring herbicide resistance by whole plant selection

herbicides issues con
Herbicides Issues (con.)

- started fall of 2001 - 4 cultivars

- .5 and 1.0x rates of glyphoste (Roundup) and glufosenate (Liberty) - a few plants survived

- 2003 study spinach tolerance to imazamox (Raptor)

- Raptor labeled cowpea - rotation with spinach

- rates highly injurious when applied preemergence

- lower rates need to be tested

- Spinach cultivars show differential tolerance to foliar application of Raptor

Russell Wallace - CES, Texas A&M

  • Bixby, Oklahoma 2002-2003
  • 3 highest yielding preemergence treatments

- Lorox (0.10 lb. a.i/A)

- Ro-Neet (3.0 lb. a.i) & Lorox (0.05 lb. a.i)

- Define (0.15 lb. a.i) & Lorox (0.05 lb. a.i)

  • Crystal City, Texas

- Ro-Neet, Dual Magnum and Outlook alone had least crop injury

- Best combination included:

Ro-Neet (3.0 or 4.0 lb. a.i) and Outlook (0.25 lb. a.i)

Ro-Neet (3.0 or 4.0 lb. a.i) and Lorox (0.05 or 0.10 lb. a.i)

Outlook (0.25 lb. a.i) and Lorox (0.05 or o.10 lb. a.i)

  • Results look promising , need more investigation regarding rates and and combinations
other topics
Other topics
  • Update on Downy Mildew of Spinach
  • Biology and Management Spinach White Rust
  • Verticillium Wilt of Spinach
  • Foliar Fungicide Alternatives in Spinach
  • Screening and Breeding for Resistance to Leafminer in spinach
  • Current and Future Insect Management in Spinach and Greens
  • Spinach Breeding in the Mid South
spinach insect pests and controls
Spinach Insect Pests and Controls
  • Paul McLeod, Department of Entomology at U. of A.
  • Aphids - Green Peach Aphid

- Scout 2 - 3 weeks prior to harvest

- 20 plants - threshold average 5/plant

- Control - imidacloprid

  • Grasshoppers

- Spinach spring and fall “green islands”

- Pyrethroid insecticides

- Other controls; location of field, “bug knockers”

Trip to University of Arkansas - Vegetable Substation - Kibler, Arkansas

- Semi Savoy - Padre

- Full Savoy - Ozarka II

  • 7,000 acres - Sharecropping
  • 800 acres Spinach and Greens, also grow acreage of Snap Beans
  • Harvesting of Greens and Spinach
  • Overwinter plantings of spinach
so after all that what did we really learn
So after all that, what did we really learn...
  • Need 15-18 # of sulfur /A in the form of ammonium sulfate - reduce need of nitrogen
  • Plant on heavier soil types - ph level important 5.8-6.2 min.
  • Can increase plant population / acre - more rows to drilling
  • Proper seedbed preparation - 4 times w/ Du-all in Oklahoma
  • shallow seeding - use of “pop up fertilizer”
so after all that what did we really learn con
So after all that, what did we really learn….. (con.)
  • Roll after planting, roll overwinter plantings in spring to level
  • Spintor for control of leafminer 2 days prior to harvest
  • Use 2-3 varieties - flat leaf types grow faster than some savoy and full savoy
  • yield goal - 7 to 8 ton/acre
  • Stomp spinach, pack tight 40,000 lb.+ per load

- 70° and lower, Oklahoma up to 3 days

- cut early mornings or evenings

- if over 80° - problems
