Study Investigator: J. Curtis, Phd
Location of Study: Florida, USA, open field
Study Period: April - May 2017
1 Pint/Acre from 1st flowers, (GS+Vegro®)
1 Pint/Acre,14 DA App 1, (GS+Vegro®)
1 Pint/Acre, 14 DA App 3, (GS+Vegro®)
No other fungicides were applied throughout this study.
Treatment 1 (T1): CONTROL or Ctrl
Treatment 2 (T2):
Treatment 3 (T3): GROWER Standard (GS)
Remark: the fungicides chosen were not utilized simulatanously but in rotation.
Foliar applications were made with a hand-held boom (CO2 operated, 40 PSI) fitted with three (3) nozzles (TXVS8) and sprayed at 50 GPA.
Anthracnose (COLLSP) evaluations were made on 6/3/2017 (5 DAF). Pepper weevil caused extensive crop loss after this time and no further fruit assessments could be made.
FRUIT COUNT, WEIGHT COUNT and PRESSURE DISEASE (Antrachnose)
All fruit were harvested from each plot (1 PLOT) at 5 DAF. Collected fruit were counted (COUNT) and weighed (LB), then bagged and kept in a large cooler (4 days at 65 degree F) for 2 days and before assessment.
All harvested fruit (5 DAF) were graded.
Fruit were graded into six (6) categories and based on size using USDA guidelines: (1 1/9 bu.box, 20 to 30 lb): Jumbo - 3 3/4 inch diam., 3 1/2inch length (45 count and fewer).
After incubation, all fruit were assessed for COLLSP disease and any lesion (regardless of size) was rated as damage. The percentage (%) damage to fruit was then calculated for each plot.
In comparison to the grower standard (GS):
For disease control:
For Quality Yield:
For fruit size distribution:
In comparison between [T2] and [T3]:
Objectives: When applied by foliar spray, to demonstrate the ability of Vegro® to improve the efficacy of the fungicides for the antrachnose control and to help to grow more natural. Main parameters monitored for this study: Pressure disease (severity); Yield (weight & fruit counts) and fruit size distribution.
For a better view of the graphs and charts, reposition your mobile device into landscape mode.
The Severity of Antrachnose is reduced by -8% between [T2] and [T3] the Grower Std. In this matter, Vegro® improves by +8% the efficacy of the fungicides added to the control and which constitute de facto the grower standard. Fungicides added were utilized not simultaneously but in rotation.
Vegro® improves the count weight difference between [T2] Vs [T3] by +65 pieces so, +25.5% progression. Here it demonstrates the ability of Vegro® to improve the quality yield.
+5 Lbs (+16.7%) difference between [T2] and [T3]. Again it shows the capacity of Vegro® to promote a yield of quality in Weight count.
Vegro® makes the difference on the fruit size distribution on Medium (-3.3%), Large (+6.2%), Extra large (+2%) and Jumbo's (0.6%). Trash is -2.5% in [T2] compared to [T3].
