Integrated Pest Management
While meant for market growers, this Integrated Pest Management guide presents an overview to Integrated Pest Management. IPM is a holistic approach to garden pest management. It uses many tools to predict and prevent pest activity before it takes hold, reducing the need for pesticides. The goal isn’t to eradicate pests, but to keep them at a managable level. Note, IPM is not organic gardening, but they have similar principals and do overlap.
This is another overview of the Integrated Pest Management approach.
