○ 2018 Results (Bog 1, Rutgers – Bog 2 (2013 and 2015 Plantings), Valley Corp – 2013
○ 4-year averages● Additional work
○ Gibberellic Acid Trial○ Predator survey
● 2019 Work Plan
2018 Performance: Yield● All plots were hand harvested on
September 24/25● Bog 1, second hand harvest on
October 3, just prior to whole farm harvest

Gibberellic Acid Trial● Cranberry (Early Black – Devlin and
Demoranville)
○ Increased yield but also smaller fruit
● Used in cherries (Rothwell, MSU, 2014)
○ Prevent flowering in young trees
○ Balance between fruiting and vegetative growth in mature trees
○ Increase colour, fruit size, firmness
○ Temperature and variety effects

Demoranville

• No increase in Demoranville yields• No effect on berry size• Mullica – decrease in berry size but not other
effects
Ground Predator Survey● OP insecticides are gone● Chance to examine potential role of
different groups of beneficial insects● Started with ground dwelling predators● Looked at different ages of farms and with
different surrounding vegetation

2019 Work Plan● Increasing grower access to the data● Herbicide Trials – Screening for Efficacy and Phytotoxicity● Harvest – Can examine impact of flooding and sitting in water,
some sort of mechanical impact on FIRMNESS (more realistic)● Square-foot harvests of the Rutgers 2016 plantings (Fruit Rot
Resistance)● Impact of different canopy management practices on different
varieties● Predator survey work
