Entomology
Also knows as phytopathology
Plant Pathology
Chemicals sprayed on weeds to control or eliminate them from agricultural fields
Weedicides
Involves the management of vegetation in agricultural production systems
Weed Science

The process of removing weeds manually to prevent their growth and spread in crop fields
Weeding
A comprehensive approach that integrates various pest control methods
Integrated Pest Management (IPR)
