Highlights

  • A Purdue University study on Flavocide has been published in the peer-reviewed Journal Ticks and Tick-borne Diseases.
  • The undiluted FLC-EW formulation achieved more than 90% mortality of deer tick nymphs at 24 hours.
  • Residual efficacy exceeded 70% mortality for up to four weeks under laboratory conditions.
  • The research was supported by the US Centers for Disease Control and Prevention.

Bio-Gene Technology Limited (ASX:BGT) announced on 7 October 2026 that research on the contact efficacy and residual activity of its Flavocide product against deer ticks has been published in the peer-reviewed journal Ticks and Tick-borne Diseases. The study was carried out by Purdue University's Department of Entomology and appears in Volume 17, Issue 6, November 2026.

Study Focus on the Deer Tick

The study targeted Ixodes scapularis, commonly known as the deer tick or blacklegged tick. This species transmits 7 of the 19 tick-borne pathogens recorded in the United States and is a major vector of Lyme disease.

The research was supported by the US Centers for Disease Control and Prevention and coordinated through the Midwest Center of Excellence for Vector Borne Disease.

Flavocide Performance Results

The undiluted FLC-EW formulation, containing 50% active ingredient, delivered more than 90% mortality of tick nymphs at 24 hours after exposure. Knock-down was approximately 50% at one hour, with robust mortality above 90% recorded at 24 to 48 hours.

Residual testing showed mortality above 70% for up to four weeks under laboratory conditions, indicating sustained activity after application.

Comparison with Other Products

The study also tested two comparison products. Talstar-P, a synthetic pyrethroid at 0.062% active ingredient, showed 90% knock-down at one hour, 70% mortality at 24 hours and above 80% mortality at 48 hours. EcoTreat/Wondercide, a cedarwood oil product, showed repellency but no toxicity.

Purdue University Professor Catherine Hill noted that the US is experiencing rapid increases in tick-borne disease reports and that new management Options are needed. Bio-Gene Executive Director R&D Peter May said the publication represents an important milestone and demonstrates promising residual efficacy.

Key Takeaways
