The organic grower will be guided by the saying “Prevention is easier and less costly than cure.” They strive to grow strong and healthy plants which resist pests and disease with natural immunity. High pest attack is nature’s quality control system removing the weak plant to prevent propagation of a poor specimen. In preference to using poisons, which kill the good with the bad, the organic grower uses products that disrupt the pest’s life cycles, comfort, feeding habits, or acts as a repellent. This allows for the preservation of predators and beneficial insects to flourish and contain pest outbreaks naturally. Only as a last resort are natural poisons like Pyrethrum used to regain control of pest attacks. Natural poisons breakdown rapidly so do not result in toxic poison residues in food or the environment.
