What are the Principles of weeds control and management?
The principles of weed control are the basis for the development of the various methods of weed control and management. There are a number of ways to control weeds. They are based on these principles.
Prevention
Stop weeds from contaminating an area. As much as possible, this preventive measure is the most effective means of weed control. You can achieve this by;
Making sure you do not carry new weed in contaminated crops seeds, feed and/or machinery.
Preventing weed from producing seeds
Preventing the spread of perennial weeds that reproduce vegetatively.
These measures can greatly reduce weed problems.
Control
This is the process of limiting weed infestation. And also minimizing competition with crops. When weeds are limited they have minimal effect on crop growth and yield. However, you can apply this principle when the problem of weed exists. It is not preventive.
Eradication
This involves complete removal of all living weed plants including their vegetative propagules and seeds. This is a more difficult approach that preventive and control. It is justified only for the elimination of serious weeds in a limited area. Example, perennial weed in a small area of a field.
