What is meant to benefit mankind as the ever increasing task to feed the over 7 billion people on the surface of the earth becomes more demanding is now a source of concern. Initially when it was introduced, it was meant to fight weeds, increase yield among several other reasons, but with time, the effects on not just the farmers but on the environment and the final consumer has drawn attention on the need to tread cautiously in the use of pesticides.
To simply put it, pesticide is any substance or mixture of substances natural, organic or man-made, used to prevent, destroy or manage pests. Different types of pesticides target different types of pests. For example, insecticides target insects, herbicides target weeds, and fungicides target fungi that may cause plant diseases. And they can either be synthetic/chemical pesticides or bio/organic pesticides.
