Application Spical-Plus

  • Hang sachets in the crop

  • Sachets already have an exit hole

  • Hold sachets by the cardboard strip at the top, to avoid damaging the predatory mites

  • Neoseiulus californicus tolerates a range of chemical pesticides

  • Always use Spical-Plus in conjunction with Spidex

Neoseiulus californicus tolerates high temperatures and low humidities. It targets all stages, but prefers younger stages. Predatory mites also survive on other mites and pollen and can survive for a number of weeks without food.
