Fruit farming
Gros Michel bananas.
Fruit farmers employ a variety of non-chemical strategies to manage pests and diseases, often integrating these methods into a system known as integrated pest management. This approach prioritizes ecological harmony and reserves chemical use as a last resort.1
Biological and Cultural Controls
- Biological Methods: Farmers utilize natural predators or parasites to control pest populations. Additionally, they select crop varieties that are naturally resistant, immune, or tolerant to specific diseases and pests.123
- Orchard Sanitation: Removing and destroying diseased plants or infested fruit interrupts the life cycle of pests and pathogens.45
- Physical Barriers: In smaller operations, growers may use protective bags to shield individual fruits from insects.4
- Trapping: Sticky traps or lures baited with pheromones can monitor pest activity and reduce adult populations.41
- Cultural Practices: Techniques such as crop rotation, pruning, deep plowing of debris, and the elimination of alternate host plants help "starve out" or physically remove pathogens. Heat treatments and the disinfection of tools are also used to maintain plant health.5
