Biodiversity and Pest Management

Also see pest management sections under specific crops.

“An ounce of prevention is worth a pound of cure” (B Franklin, 1706-1790). Since Ben Franklin made this famous statement, integrated pest management and organic practitioners have stressed the prevention of pest problems using cultural methods, enhancing natural enemies and choosing pest resistant varieties. When these methods are insufficient it is sometimes necessary to use natural or synthetic products to manage pests. Insect, disease and weed management resources to guide decision-making are highlighted below.
