Inorganic : A fertilizer made from a source that was never alive now or in the past.

Insecticide : Product used to control insects.

Instar : The larval or nymph stage of an immature insect between successive molts. Any of the successive nymphal stages in the metamorphosis of insects or the stages of larval.

Intercropping : Is the practice of cultivating an additional crop in the spaces available between the main crop.
