Albaugh – Zelto Biological Nematicide – 1 GAL

Zelto is a biological insecticide and nematicide formulated with heat-killed Burkholderia spp. strain A396 cells and spent fermentation media. Designed for turfgrass, ornamentals, and labeled agricultural crops, Zelto provides true nematicidal activity against eggs, juveniles, and adult plant-parasitic nematodes while also suppressing certain soil-dwelling and foliar insect pests.

Zelto works through enzymatic degradation of exoskeletal structures and interference with molting, leading to pest mortality through contact and ingestion. It supports turf density and root health while fitting into integrated pest management and organic production programs.
