1) pesticides
2) herbicides
3) fertilizers
4) anything else the stupid examiners test us on related to this question  >:(

Pesticides kill the pests (insects) tht ummm annoy the plant :P.
Herbicides kills the unwanted plants like weeds etc.
Fertilizers helps plants grow (they contain NPK - Nitrogen, Phosphorous and Potassium which are essential for plant growth )
;D

in addition to that, fertilizers cause aquatic plants to grow rapidly at first (algal bloom)
then cause them to die. but not sure for herbicides and pesticides though. sorry  :(
