Resistance management

Strategies for avoiding and/or managing the development of resistance are provided as follows:

  • Where possible, application treatments should be recommended to be combined with nonchemical measures.
  • Applications should always be made against the most susceptible stages in the pest life cycle.
  • Where an extended period of control is required, treatments should be alternated with products with different mode of action.
  • Levels of effectiveness should be monitored, and instances of reduced effectiveness should be investigated for possible evidence of resistance, noting that sanitary conditions and proximity of untreated refuges can contribute to the risk of reinfestation.
  • In cases where label rates, correctly applied, fail to give the expected level of control and resistance is demonstrated, use of any product containing active substance with the same mode of action should cease.
