Beneficial Nematodes
Precisely Target Pests – Sustainably
with Retaliate – BN Series Beneficial Nematodes
Asymmetry Inc.’s Retaliate BN series features proprietary formulations of naturally occurring, insect-parasitic beneficial nematodes for targeted agricultural pest management. Cultivated and distributed domestically, these nematode-based biological solutions are designed to address specific insect pests while providing an alternative to conventional chemical pest control methods.
Beneficial nematodes seek out susceptible insect hosts and enter their bodies, releasing symbiotic bacteria that cause infection and kill the host. Asymmetry offers selected nematode strains selected to target particular insect pests. When used according to product directions, these biological solutions can be incorporated into pest management programs to help control target pests while minimizing reliance on conventional chemical treatments.

Production and Quality Control
Our advanced production methods of the Retaliate B/N range focus on meeting the demands of our customers. We choose to produce our Nematodes in multiple small batches – rather than a single large-scale batch – to ensure that a failure in one batch, does not interfere with our ability to meet order demands.

Product Quality and Quality Control are of the upmost importance to us. Our quality control steps include:
- Health, counts and genetic analysis of the symbiote bacteria
- Standardization using specific concentrations and purity
- Inoculation of EPNs and measuring growth rates
- Harvesting and separation of infective juvenile stage
- Counting and purity testing in final product
- Cold room packaging and proper storage temperature
Asymmetry is well-versed in fermentation and equipped to perform DNA analysis of our target organisms. We pride ourselves in our commitment to quality at every step along the way. This ensures the maximum number of IJ nematodes in every tray we deliver.
As living organisms, Beneficial Nematodes are also sensitive to distribution times. Our location in the southeastern United States (Atlanta, GA), reduces shipping times and allows us to more effectively serve our customers all across North America
