    Objective

    Evaluate the effects of the rate and application method of PRB9 applications on the yield and quality of citrus fruit during winter stress.

    Overview

    • Plants in the field can be exposed to many kinds of abiotic stress including severe cold which can inhibit the normal growth and activity of a plant leading to decreases in yield and quality of a crop.
    • PRB9 contains an osmolyte compound which increases resistance to abiotic stress and optimizes conditions for improved crop yield and plant performance.

    Trial Details

    Crop: CITRUS
    Year: 2023-24
    Number of Trials: 3
    Location: United States – Central California
    Data Source: Field study was conducted by third-party, independent researcher
    Treatments:
    1. Untreated Control (UTC)
    2. PRB9 soil applications; 3 applications at either a low or standard rate
    3. PRB9 foliar application; 1-3 applications at standard rate depending on temperatures
    4. Soil or foliar applied competitor products
    Cultivar: Tango or Murcott
    Cropping Conditions: Trial conformed to local cropping practices.
    Application Rate: 32 or 42 fl oz/ac
    Application Method: Foliar applications made with mist blower; soil applications applied as a drench.
    Application Timing: Foliar application made before expected freezing temperatures. Soil applications made on regular basis during cold season.

    Results

    Performance in Citrus

    Summary

    • Soil applied PRB9 increased fruit diameter shifting the harvest into more of the larger, heavier fruits and producing higher overall yields.
    • Foliar applications of PRB9 produced similar results to the soils applications although the effects were not quite as large.
