Tells you about the conditions surrounding the vine
Know the Real Condition of Your Vines and Planting Material Even During Dormancy
During dormancy, some of the signals growers normally rely on become limited. External appearance may reveal very little about the physiological condition or viability of the plant
PhytoTester reads bioelectrical signals directly from the plant to provide a plant-level vitality assessment in just 5-10 seconds
That gives growers, nurseries, and agronomists another source of information when assessing vines and planting material — before planting and before visible signs become the only warning

Decide Before You Plant
Planting material can look identical while its physiological condition tells a different story
PhytoTester adds plant-level information while the batch can still be screened and a better decision is still possible
That makes earlier plant-level information valuable
Before planting
screen planting material before it becomes a long-term vineyard decision
Before the season
review established vines while replacement work can still be planned
A decision made before planting can shape the vineyard for years
Tells you about the environment in which the vine is growing
Shows you what has already become visible
Adds bioelectrical information taken directly from the plant itself
See Another Signal Before Visible Symptoms Become Your Only Warning
PhytoTester does not replace field observation, soil data, weather information, laboratory testing, or agronomic expertise. It adds another source of plant-level information to the decision
We Measure. We Do Not Estimate.
Smart PhytoTester captures the signal, the mobile app manages field work, and phytotester.ai turns synchronised measurements into verifiable decisions
Measure Directly From the Plant
The device records bioelectrical signals directly from vines and planting material without damaging the plant
Each individual measurement takes about 5–10 seconds and provides the input used by the connected ecosystem
Run the Measurement Workflow in the Field
The app connects to Smart PhytoTester, creates a batch or plot, guides representative sampling, displays PVI and quality categories, and supports full-stock sorting when needed
Sessions are saved offline and synchronised automatically when the connection returns, so field data is not lost
Turn Measurements Into Verifiable Decisions
The platform manages batches, plots, devices and session history; issues immutable batch passports with public QR verification; and creates establishment reports from measured batch quality
It compares three planting strategies, tracks predicted versus actual establishment, and provides portfolio-level visibility for farms, nurseries, consultants and cooperatives

How the Ecosystem Works
One clear flow—from measurement to a decision you can verify
Know the quality of a batch before you plant
A representative screening turns 50 individual measurements into a clear batch-level result
01
Create the batchAdd variety, rootstock, nursery, year and total units in the mobile app
02
Measure 50 plantsThe app guides sampling. Each measurement takes about 5–10 seconds
03
See the real countView high-, medium- and low-grade material in percentages and actual units
04
Decide and documentSort the stock or accept the batch, then synchronise it with phytotester.ai
Check whether the prediction matched reality
Close the loop by comparing predicted establishment with the actual count
01
Add the plotLink the measured batch to its destination plot
02
Compare strategiesReview three planting scenarios and their financial implications
03
Count establishmentRecord the actual number of established vines after planting
04
Validate the resultCompare prediction with reality and retain the result for calibration
More Than a Percentage
A measurement becomes a decision, a document and a result you can check
PhytoTester shows what the result means in plants—not only in percentages
Plant Vitality Index
Classify planting material
Assess each plant without damaging it and place it in a clear quality category
Built for nurseries, grafting-material producers and pre-planting decisions
Batch Passport
Make the result verifiable
Issue an immutable passport with a public code, QR verification, method version and category distribution
The passport complements—not replaces—varietal and phytosanitary testing
Establishment Report
See the decision in numbers
Compare three planting strategies, expected establishment and the estimated twenty-year difference
After planting, compare the prediction with the actual count

PhytoTester in Practice
Three real measurement workflows in nursery and field conditions
01 · Nursery screening
Rapid Screening of Grafted Seedlings
Plant-level measurements taken directly from grafted nursery material
02 · Comparative test
Comparing Grafting Material
Measurements reveal differences that are not obvious from appearance alone
03 · Field selection
Selection of Rooted Plants
Fast non-destructive assessment in real field conditions
What We Claim — and on What Basis
Published research, field testing and transparent validation behind the product
Published Research — AGROSYM 2023
What can bioelectrical signals measured from a plant tell us about the condition and vital activity of the plant itself?
Research by Tamaz Bichiashvili and Shalva Bichiashvili presented PhytoTester as a portable instrument for assessment of plant vital activity
The experimental work included vine planting material, grafting components, and grafted nurslings
The published conclusion reports that PhytoTester can assess the physiological condition of plant nurslings and grafting components in 5-10 seconds, without damaging the material

Biophysical Methods for Express Diagnosis
PhytoTester’s research base also includes earlier work on biophysical methods for express diagnosis of plant physiological status and their application to planting-material production
Denmark Validation
PhytoTester was selected as one of 13 projects for commercialisation under Georgia’s Technology Transfer Programme
The Ministry of Economy and Sustainable Development’s 2025 report also records testing of the technology in Denmark with local farmers, greenhouse operations, and agribusiness representatives
Independent Production Testing
PhytoTester has also been tested with vine grafting and grafted material in production conditions with independent participation
According to the testing material supplied by PhytoTester, the results supported rapid assessment of grafting material and rooted grafted plants without damaging the tested material
