Congress grass: Ever been asked to stay away from this wild grass that causes itching? This plant became not only uninvited guest but also threat to our own crop. Thanks to America. ‘Congress grass is the deadliest weed that we have in India thanks to the government’s decision to import an innocuous variety of wheat, PL-480 from the US in the 1950s and this weed came with it – in fact, the deadly weed is named “Congress” grass because it was imported into the country by the then Congress government in centre.
It spread rapidly across the country and it is estimated that in the last 50 years, over 350 lakh hectares of land in the country (or over 10% or our land area) including 20 lakh hectares of arable land has been infested by this deadly weed. The cumulative loss on account of this weed till date with its impact on humans, animals as well as crops so far has been estimated at a whopping Rs.160,516 crores.’ - Quora
