Various nematode species can feed on the roots of the plant. Furthermore, they can create malformations in onion’s growth, making it easier for the entrance of secondary pathogens like fungi and bacteria.  This can be prevented by using Telone® II soil fumigant or Telone C-17 soil fungicide and nematicide.

Including fumigation in your IPM program will help make your  onions reach their full potential. Telone soil fumigants move through the soil to create a zone of protection around developing roots.
