BioCeres® WP is a biological insecticide made from the spores of the ANT-03 strain of the Beauveria bassiana entomopathogenic fungus. It is certified organic in Canada and the United States. Due to its unique makeup, it may not have the same compatibility with certain pesticides (insecticides and fungicides) as other Beauveria bassiana-based products.
Compatibility tests
Compatibility tests were conducted in the laboratory of Anatis Bioprotection’s bio-insecticide division, by Martin Nadeau, PhD, Scientific Director, and Jorge Fernandez, M.Sc. The tests involved measuring the germination of Beauveria bassiana spores (%) after mixing BioCeres® WP with the tested products. The doses (weight/volume) used for the tests respected the manufacturers’ recommendations.
Incompatible or moderately incompatible pesticides
Some pesticides have been deemed incompatible with BioCeres WP. In the laboratory tests, these products considerably reduced or completely stopped the activity of the Beauveria bassiana spores. Unable to form properly, the spores were ineffective at contaminating and killing pest insects. It is therefore recommended that users wait five or more days before applying an incompatible pesticide.
Moderately incompatible pesticides can reduce spore activity by 30% to 40%, thus partially reducing the treatment’s effectiveness. They can be mixed with BioCeres, but it is preferable to adjust the doses accordingly.
An ongoing project
Over the next several years, Anatis Bioprotection, with the help its partner BioSafe Systems, will be testing different pesticides to expand knowledge of compatibility and maximize the effects of spray applications. This document, found in the BioCeres WP sheet, will be periodically updated.

- Compatible
- This fungicide/insecticide can be mixed with BioCeres WP.
- Moderately incompatible
- If this fungicide/insecticide is mixed with BioCeres WP, the spore action will decrease (30% to 40%) or stop.
- Incompatible
- We do not recommend mixing this fungicide/insecticide with BioCeres WP. Stagger applications according to the directions on the label.
