The project team has continued its work through April to evaluate non‑destructive technologies that growers can confidently and easily use on‑farm. Growers have strongly indicated that a practical, accurate, non‑destructive option would be valuable, and the project team is actively pursuing solutions that meet those expectations.

Currently, refractometers remain the most reliable tool for measuring and predicting fruit maturity on‑farm. While several non‑destructive technologies have shown promise, none are yet at a point where they can replace a refractometer with the level of precision and consistency growers need. One AI‑driven modelling tool, for example, performed well in controlled laboratory testing but was eliminated after extensive on‑farm trialling showed it could not deliver accurate results under real‑world conditions.

Other technologies - including NIR (near‑infrared) devices and a new technology currently being developed for watermelons - are still tracking positively. Further work is underway to determine whether NIR devices can deliver the accuracy and ease of use that growers need.

Project Lead, Mark Loeffen, says the team remains committed to finding a workable solution: “Growers have been very clear about the need for non‑destructive options, and we’re putting a lot of effort into evaluating technologies thoroughly. Even when a tool doesn’t make the cut, it still gives us valuable information that helps guide the next steps.”

The search for a precise, accurate and grower‑friendly non‑destructive measurement option is ongoing and remains a key focus for the project team.
