Key Points

To examine the interactions between chemical herbicides and soil-borne pathogens in the development and severity of plant root diseases.
Reviewed scientific literature and experimental evidence regarding the direct and indirect impacts of herbicides on soil microorganisms and plant hosts.
Assessed mechanisms including altered host plant defense mechanisms, root exudation changes, and shifts in pathogenic fungal populations.
Herbicides demonstrate variable influences on root diseases, occasionally suppressing pathogen growth or predisposing host crops to increased infection.
Interactions depend heavily on chemical class, application timing, host physiology, and indigenous microbial competition within the rhizosphere.

Review reveals how herbicide applications alter soil-borne root diseases in crops, highlighting unintended pathogen interactions.
