The application method of PreFeRal® WG depends on the crop and the number of whiteflies present.

• Spraying:
  PreFeRal^® WG should be applied with conventional spraying equipment. PreFeRal^® WG works as a contact insecticide. In order to obtain an efficient insect control, the undersides of the leaves should be properly covered. It is recommendable to use sufficient quantities of water. The volume of water needed depends on crop development. Usually, selection of high spray volume will provide the best results. It is recommended to apply 2.000 - 3.000 l/ha on full-grown and 1.000 l/ha on small or young crops.
  The optimal pH of the water should be between pH 4 and pH 7.
• Integrated Pest Management Programme:
  PreFeRal® WG can be used in combination with beneficials such as Encarsia formosa, Eretmocerus californicus or Macrolophus caliginosus. This makes PreFeRal^® WG an outstanding correction agent when biological control needs some extra help with whitefly control. This is called "Integrated Pest Management" (IPM).
• Integrated Resistence Management Programme:
  PreFeRal® WG can be applied in combination with selective whitefly insecticides as a part of an Integrated Resistence Management Programme (IRM).
