Prime Source: A Division of Albaugh and Zelto and Crescendo Biological Nematicides/Insecticides
The powerful biological combination of OMRI-listed Zelto® and Crescendo™ provides excellent control of the most destructive turf nematodes and both are great rotational partners with conventional chemistries.
Zelto has a novel bacteria based (non-living) active with true nematicidal activity
against eggs, juveniles and adult nematodes.
Crescendo contains a heat-killed biological multi-site active ingredient that repels, stops feeding, reduces reproduction, and induces mortality to prevent damaging populations of sucking and chewing insects, flies and mites.
In recent university trials, tank mixes of Zelto® and Crescendo™ biological nematicides/insecticides significantly reduced populations of turf nematodes. Check out the trial results and more about both products here.
