Preventing resistance

In order to prevent a crop from developing resistance, is a broad range of crop protection agents is required. That is why they can choose to only stop using an application when at least five resistance groups remain available. When an agent is substituted by an alternative agent from the same resistance group, the number of resistance groups will not reduce.

Overview of resistance groups

An overview of the resistance groups of crop protection agents can be found on the following websites:
  • IRAC (resistance groups of insecticides)
  • HRAC (resistance groups of herbicides)
  • FRAC (resistance groups of fungicides)
