IARI is a premiere agriculture research institute of India. They produce wonderful scientific toys to play with for seed companies. 😉 And so seed companies can make profit by selling toys to farmers by showing them high yield dreams. 😉
Their recommended cultivation practices for wheat and barley prescribes farmers to use Imidacloprid or quinalphos , a systemic insecticide which acts as an insect neurotoxin and belongs to a class of chemicals called the neonicotinoids which act on the central nervous system of insects with much lower toxicity to mammals.
Imidacloprid is highly toxic to four bird species: Japanese quail, house sparrow, canary, and pigeon. It triggers colony collapse disorder (CCD) in bees. It is neurotoxin for humans. 
Why esteemed scientists suggest such disastrous prescriptions? 🙂
