How to Manage Pests

Pests in Gardens and Landscapes

Water mismanagement

Mismanagement of water is a major contributing factor to many pest problems and also causes damage on its own. Too little water can result in small plants, poor root systems, and slower growth and exacerbates the effects of pests such as root nematodes that injure roots. Excessive water can contribute to the development of many diseases. Uneven distribution of water can encourage weeds and disease problems and prevent uniform maturing of the crop.
