    Objective

    Evaluate the effects of the timing and rate of BioPath® applications on the yield and quality of Table Grapes.

    Overview

    • Some applied fertilizer and other soil nutrients are unavailable to the plant during nutrient uptake due to complex physical and chemical interactions.
    • Some soil microbes can influence these interactions to increase plant nutrient availability and improve nutrient uptake and utilization, resulting in increased plant biomass and vigor.
    • Some products (e.g., BioPath) contain multiple bacterial species that are specifically selected and formulated to promote plant nutrient availability.

    Trial Details

    Crop: TABLE GRAPES (Vitis vinifera)
    Year: 2023
    Location: United States – Central California
    Data Source: Field study was conducted by third-party, independent researcher
    Treatments:
    1. Grower Standard
    2. High rate of BioPath applied once, twice or three times during the growing season
    3. Low rate of BioPath applied twice or three times during the growing season
    Cultivar: Krissy
    Cropping Conditions: Trial conformed to local cropping practices. Established vines with conventional tillage
    Application Rate: 16 and 32 fl oz/ac
    Application Method: Soil drench during active irrigation
    Application Timing: Variable applications at prebloom, berry sizing and verasion

    Results

    Performance in Table Grapes

    Summary

    • BioPath treatments applied at 16 oz/ac during berry sizing and verasion resulted in higher yields and produced more larger and heavier berries than the untreated controls.
    • Increasing the rate or number of applications above the two 16 oz/ac application did not provide any additional benefits except an increase in Brix levels.
    • The trial experienced heavy rain in August due to a rare hurricane event. The rain caused swelling and cracking in the developing fruit that led to a lot of rot and lower yields than is typical for the region.
