SUMMARY:

  • CrabLife treatments maintained healthy canopy growth and increased canopy area by up to 13% compared to the untreated control during the late growing season (123-151 DAT).
  • CrabLife treatments increased Nov yield by 29% to 48%, but these increases were not statistically significant.
  • CrabLife treatments significantly increased Feb and Mar yields by 10-16% and 17-27%, respectively, compared to the untreated control.
  • CrabLife treatments significantly increased total marketable yield by 15-16% compared to the untreated control.
  • Yield increases by CrabLife treatments were due to increased fruit set (11-21%↑).
  • CrabLife treatment at 40 lb/acre increased the proportion of small fruit yield but decreased the proportion of disease fruit compared to the untreated control. The proportion of marketable fruit was unaffected by CrabLife treatments.
  • Fruit Brix was unaffected by CrabLife treatments.

Strawberry Field Trial

Gulf Coast Research & Education Center

First Year Blackberry Primocane Yields

Soil amended with CrabLife Flake and rice bran;
drip irrigated with CrabLife Powder and compost tea

Average market price: $13/crate
Revenue increase: $10,179/acre
Material cost: $1,010/acre
Net to grower: $9,169/acre
CrabLife amended soil resulted in a 40% increase in marketable yield

Conventional Strawberry Grower Trials

Watsonville, CA, Summer 2016

Eight-week application period of CrabLife Powder plus compost tea through the drip irrigation at 2.5 lbs. per acre diluted in 1,000 gal. water applied twice weekly (40 lbs. total).

Plant City, Florida, Spring 2017

Eight-week application period of CrabLife Powder plus compost tea through the drip irrigation at 2.5 lbs. per acre diluted in 1,000 gal. water applied twice weekly (40 lbs. total).

Wimauma, Florida, 2017-2018

CrabLife Powder applied through the drip irrigation system at 5 lbs. per acre for 8 weeks beginning 2 weeks after transplanting (40 lbs. per acre total).
