Pest management aspects of crop rotations

This site provides comprehensive information on various aspects of crop rotations, such as to combat specific pests, by removing their host for a season or more. Rotations can be used to prevent buildup of a particular pest (e.g. soil-borne nematodes) or increase management options (e.g. planting a broadleaf crop to allow the use of grass herbicides).

Hard to control weeds such as wild oats, paradoxa grass (wild canary), and buckwheat can be managed by a well managed period of winter crop rotation with summer cropping.

Crop rotation can also effectively control diseases which survive in the soil or on crop residues. It breaks the life cycle of these disease organisms.
