Agronomic Protocol
  • Grapefruit tree, (white on swingle root stock), 28 years old. 12 feet high on average and hedged every year.
  • Row spacing 24 ft. x 14 ft.
  • Each plot comprised 5 trees (24 ft. width x 70 ft. length) and each plot was separated by an untreated buffer tree.
  • 4 replicate plots per treatment.
TREATMENTS
  • CONTROL (Ctrl)
  • NO fungicides were applied to the test section during this study.

TOTAL: 4 applications 

  • [T1] CONTROL (Ctrl)      
  • [T2] Ctrl + HEADLINE @ 12 fl. oz. per acre + NIS @ 0.125% V/V
  • [T3] Ctrl + QUADRIS TOP @ 15 fl. oz. per acre + NIS @ 0.125% V/V
  • [T4] Ctrl + CYAN 365® @ 1 quart per acre
  • [T2] & [T3] are Grower standards.
NOTES:
  • It is also to noticeable that this study has been realized concomitantly with the one for Melanose.
  • Exact same population of trees and fruits. 
  • Same treatments
  • Same period of time
DETAILS
  • Agronomic study conducted in open field in genuine & authentic conditions.
  • One's most reputed citrus grower in the Indian river district, FL, USA
  • Study realized in a grove of about 1,000 acres
  • Groves where Greening (HLB) disease is present at 100%, where there is canker, greasy spots, Melanose, leaf miner, ruste mites...

<strong>In comparison to the grower standard:</strong>

For Disease Control:

  • -3% Less Greasy spots severity on FRUITS between [T3] and [T4]
  • -8% Less Greasy spots severity on FRUITS with [T4] Ctrl+Cyan 365® and [T1] Ctrl alone. This shows the potential of Cyan 365® bby itself.
  • -50% Reduction rate on FRUITS of the Greasy spots severity between [T4] and [T1]

For Quality Yield:

  • +10 Pcs (+3%) More fruit count between [T4] Cyan 365® than [T3] Grower Standard
  • +7 Lbs (+5%) More weight count between [T4] Cyan 365® than [T3] Grower Standard
  • NS (non significant) less premature fruit drop between [T4] Cyan 365® and [T2] & [T3].
  • +88 Pcs (+35.3%) More fruit count between [T1] Ctrl and [T4] Ctrl+Cyan 365®
  • +20 Lbs (+15%) More weight count between [T1] Ctrl and [T4] Ctrl+Cyan 365®

For Early fruit drop reduction:

  • -62 Pcs (+31.5%) Less premature fruit drop count between [T1] Ctrl alone and [T4] Ctrl+Cyan 365®.

For Fruit Size Distribution:

In comparison to the grower standard untreated:

  • +100% for size 23ø
  • +4% for size 27ø
  • +2% for size 32ø
  • +7% for size 36ø

Objectives: To demonstrate the ability of CYAN 365® to improve the efficacy of the fungicides for Greasy spots control reduction but also to help to grow more quality yield, more natural, more sustainable and more profitable. Main parameters monitored for this study: Pressure disease (Greasy spots on fruit), for yield (early fruit drop + weight & fruit counts + fruit size distribution).

Severity of the Greasy Spots

CYAN 365® alone in [T4] demonstrates that alternative solutions with natural products can perform as well if not better than chemical products. Here we see that the severity of Greasy spots on the fruit is even more efficient with Cyan 365® alone [T4] than in [T3]. It also demonstrate here the ability of Cyan 365® to play on this fungal disease. It helps to reduce the presence of Greasy spots on the fruit of about -50% in comparison between the control alone [T1] and the Ctrl with Cyan 365® [T4]. Also check the numbers on fruit count and weight count within the same comparison.Cyan 365® is not a fungicide but it shows here clearly what could be the interest to combine it with fungicides.

Fruit count (in pieces)

Fruit count difference wise (in pieces), Cyan 365® alone [T4] shows its ability to compete against the Grower Standards in [T2] & [T3]. It is even surpassing by +10 pcs [T3]. Between [T1] Ctrl alone and [T4] Ctrl+Cyan 365®, there is +88 pcs (+35.3%) of fruit count difference.

Weight Count (in Lbs)

Weight count difference wise (in Lbs), Cyan 365® [T4], same thing, it competes against the Grower Standards in [T2] & [T3]. It is even surpassing [T3]. Between [T1] Ctrl alone and [T4] Ctrl+Cyan 365®, there is +20 Lbs (+15%) of weight count difference. It is even surpassing [T3]. With Cyan 365®, you grow more natural, more sustainable and more profitable!

Premature Fruit drop Count (in pieces)

Less drop count wise [T4] Cyan 365® alone shows its ability to compete against other Grower Standards [T2] & [T3]. [T4] Ctrl + Cyan 365® compared to [T1] Ctrl alone, shows the interest of Cyan 365® on the premature fruit drop reduction, -62 pcs (-31.5%). With Cyan 365®, you grow more natural, more sustainable and more profitable!
