Food for Thought

  • Premium Grape = Premium Wine
  • Balanced Vine = Balanced Fruit
  • Dollar Spent = Loss or Profit
  • Takes 5 years to find out we made a mistake
  • Never to old to learn
  • Don’t get set in your ways

VINEYARD MECHANIZATION

  • History
  • Development of Complete Vineyard

Mechanization System (Justin Morris)

  • Preparation For Successful Vineyard

Mechanization (Dr Striegler & Eli Bergmeier)

Development of Mechanization

  • 1950 - UC Davis - first attempt for mechanical

harvest

  • 1957 - Cornell - first unit to be developed for

commercial use (Chisam Rider)

  • 2016 – Oxbo – Braud – Pollenc – Gregoire –
  • Etc. to fit any trellis system
  • Units are 99% Effceint with MOG removed

Development of Complete Vineyard Mechanization System (Justin Morris)

  • 1970 – Morris started development of total

vineyard mechanization system

  • Worked with Tommy Oldridge a grower and

inventor to develop 40 different machines and attachments of which 20 already existed

  • Operations included dormant and summer

pruning, leaf removal, shoot and fruit thinning, canopy management and harvest

Labor Cost

  • Labor cost comparison for conventional and

mechanical canopy management of ‘Cabernet Sauvignon’ grapevine in Fresno, CA.

  • Hand Pruning $403.59
  • Mechanical prepruning with hand shoot

thinning $153.42

  • Mechanical box pruning with mechanical

shoot thinning $81.54

Mechanical Canopy and Crop Load Management

  • Mechanization of canopy and crop load (Ravaz

index; RI) management in vineyards was shown to reduce labor costs by 44 to 80%, maintain yield and quality at the farm gate, and reduce the overhead associated with human resources (Kurtural et al. 2012, Morris 2007, Poni et al. 2004).
