In the past year, Koppert has greatly improved the Natutec Scout app. The new version was tested by RedStar — the Netherlands' largest producer of exclusive taste tomatoes and snack tomatoes. The company is very satisfied with it. ‘We don't really need to scouting for whitefly any more. You photograph the sticky traps, and this immediately tells you how the level of infestation is developing.’
At RedStar, Jan van Nieuwkerk is responsible for plant protection at the company's six locations in Voorne-Putten. In total, this amounts to a 28-hectare area. Jan has used the Natutec Scout app since its market launch. Last year, Koppert asked him to test a number of improvements and report back on his findings.
The scan function made more powerful
This testing is ongoing at RedStar, but Jan now has a clear conclusion about the new version: it is a significant improvement. First of all, the scanning function was made much more powerful, he says. ‘In the past, when the sticky traps were read for whitefly, the results were sometimes too high or too low. That’s now a thing of the past. Thanks to a higher resolution, the device scans much more accurately. Whitefly is now very accurately recognized. I now have more trust in the result.’
From Jan’s point of view, it is not even about the exact number of whitefly stuck on the sticky traps. ‘No,’ he says, ‘I am more interested in seeing the trend. Is the level of whitefly infestation staying the same or is it going up or down? I want to see that at a glance. If there is an increasing level of infestation, I can then quickly take the right measures.’
Although he still keeps an eye on the level of whitefly eggs laid, Jan says scouting for whitefly is no longer necessary. We photograph the sticky traps and immediately see how the level of infestation is developing.’
A lot of time saved
This trend in level of infestation pressure is now visible in easy-to-understand graphs. ‘It's about that line. Is it going up? Down? Or is it staying the same? That's what I want to see,’ says Jan. ‘In addition, our scouts and I save an enormous amount of time compared with the former manual counting. Moreover, we can easily record our findings and quickly share them with each other or with the consultant. That also saves time.’
The Natutec Scout app can also be used to monitor other pests. Koppert is working on making it possible to scan and recognize them. ‘We can already enter our counts. The map or graphs then show how the level of infestation is developing. This function has also been made faster and better.’
