  • Reduction of Beet Cyst Nematodes (Heterodera schachtii) up to 90 %, resistance level 2+
  • Efficient reduction of Root Knot Nematodes (Meloidogyne chitwoodi and M. fallax) and Root Lesion Nematodes such as Pratylenchus crenatus, P. neglectus und P. penetrans
  • No multiplication of Stem and Bulb Nematode (Ditylenchus dipsaci)
  • DEFENDER suppresses the Stubby Root Nematodes and therefore leads to a reduction of Corky Ring Spot in potatoes
