Benefits of Versys

  • Versys insecticide has a new, unique mode of action known as chordotonal organ TRPV channel modulators.
    IRAC Group 9D.   
  • The chordotonal organs are biological stretch sensors.
    They may be located in the antennae, mouth, legs, wings or thorax of insects.    
  • These stretch sensors provide insects with their senses of hearing, orientation and balance.
    In insect leg joints, the same sensors are critical for coordinated movement.  
  • Versys acts selectively on these stretch sensors making it impossible for the insect to detect sound, gravity and the movement and position of body parts.   
  • Deaf, disoriented and uncoordinated, insects affected by Versys rapidly cease feeding.
