Application Thripor-I

  • Shake bottle gently before use

  • Spread material on clean rock wool slabs, leaves and/or in application boxes (Dibox)

  • Apply in groups of 75-100 insects in order to establish a population and encourage mating. In this way it is possible to check on reproduction

  • Make sure the material remains undisturbed in the introduction site for a few days
