Q.What are Agro chemicals ?

Agrochemicals are chemicals -- fertilizers, pesticides, growth regulators -- applied in agriculture to raise yield and protect crops.

Agrochemicals are chemical products used in farming to increase agricultural productivity and to protect crops from pests, weeds, and diseases. They are broadly grouped as follows:

1. Chemical fertilizers: synthetic compounds that supply essential plant nutrients, principally nitrogen (N), phosphorus (P) and potassium (K), along with secondary and micronutrients, to boost soil fertility and crop yield.
2. Pesticides: chemicals used to kill or control organisms that damage crops -- including insecticides (against insect pests), fungicides (against fungal diseases), herbicides (against weeds), and rodenticides (against rodents).
3. Plant growth regulators: chemicals applied to influence plant growth and development, such as promoting flowering, fruiting, or controlling plant height. …
