Frequently Asked Questions

Biorationals are low-impact substances or products that are typically biologically derived. If biorationals are synthetic, they are structurally similar and functionally identical to biologically occurring material (with minor differences between the respective stereochemical isomer ratios derived from biological or synthetic origins).

Biorationals include biopesticides and non-pesticidal products that have multiple uses, including crop stress management, enhanced plant physiology benefits, root growth management, and postharvest treatments, or as an alternative control agent to conventional pesticides and antimicrobials.

Source: ASTM, April 2013

Pest control products have gone through a great deal of scrutiny in recent years. Governments have limited the use of conventional chemistries that have been part of crop protection programs while at the same time, today’s growers are expected to produce more food than ever.

Valent BioSciences’ products offer growers solutions that can increase productivity with minimal impact to workers or the environment. Our products include a low risk profile and help maintain beneficial insect populations such as pollinators. Biorationals also help sustain the efficacy of today’s conventional chemistries, which may be prone to the onset of resistance when overused.

In the public health and forest health industries, the same issues exist around traditional chemistries. But biorationals from Valent BioSciences have little to no impact on non-target organisms and humans while targeting specific pests.
