Cultural control relies on planting factors such as crop rotation and planting after weeds have been killed following germination. Good management starts with scouting fields on a regular basis. Keeping records of past problem areas helps control pests, as well as the need for chemical means of controlling pests.
The first step is to determine the seriousness of the infestation of weeds or insects. This is where trade-offs take place.
Will the potential loss of crop yield be greater than the cost of chemical treatment?
Are there other options that might be cheaper and less environmentally dangerous?
There are no set answers since each farm is different and each year brings new challenges.
