Every farmer has to answer this for him/herself. Integrated Pest Management (IPM) should always be considered when the crop is being planned. Contact-kill pesticides should never be applied until the number of pests has risen to a level where economic damage is occurring. Once the number of pests has risen to an unacceptable level, only approved pesticides should be applied by a trained, licensed operator.
