Step-by-step solution
Biocontrol refers to the use of biological methods for controlling plant diseases and pests. In modern society, these problems have been tackled increasingly by the use of chemicals – by use of insecticides and pesticides.

Our soil is also polluted through our use of weedicides to remove weeds.
