Make pesticide

Conventionally, farmers use synthetic pesticides to manage pests which could be effective at keeping pests away but also come with much unanticipated negative side effects.

Synthetic pesticides are relatively expensive and cause more harm than good to the environment.

They also kill beneficial organisms in the ecosystem.

The overdependence on synthetic chemical pesticides due to their probable rapid knockdown effect kills natural predators, therefore, reducing the ability of the ecosystem to naturally manage pests.

Starting out

This is how to get your hands dirty to manufacture your own biopesticides with your household items at home.
