Koppert nematoden

Koppert Biological Systems, has developed a gel formulation for its nematode range. A formation that will increase the shelf life of these highly effective biocontrol organisms, and ensure that no visible residue is left on the leaves or fruit of the crop.

Nematodes have been relied upon in horticultural crops for many years. The strength of the nematodes is that pest insects cannot build any resistance against them. That means that they are a very stable factor with regards to crop control.

After a long trajectory of research and development, the company is replacing its clay matrix (in which the nematodes remain in a dormant state until released) with a gel formulation which significantly lengthens the shelf life by a number of weeks (up to 16 weeks in some cases). ‘This is because nematodes use less energy during their hibernation in the gel formulation. When used on time, they are more energetic to do the job they were made for,’ Product Manager at Koppert, Tim Bossinga, explains.

The fact that there’s no visible residue, is another major advantage for the end-user, because the new formula, dissolved in water, is a transparent solution. The former clay medium left a whitish film on the final product, which was affecting the economic value of ornamental crops especially.

Processing this medium is also much easier. The gel dissolves easily and homogeneously in water, contrary
to the clay which sometimes lumped together.

Correct application is crucial for the effectiveness of this biological solution. That’s why Koppert released a new ‘how to use’ video. Click here to watch the video.
