Weeds May Be Divided Into

They are the annual plants botanically called Parthenium hysterophorus
and popularly known as Congress Grass or Carrot Weed.

It belongs to the botanical family, Asteracae.

These plants are very difficult to eradicate.

It appears that Parthenium is not native to India, but it came with
the imported wheat as a mixture, when the US sent wheat to India under
PL 480 (Public Law 480 passed in 1954 to give food grains to
developing countries) in 1956.

However this concept was contradicted by some as not the real story
because Parthenium was present in India even in 1951 itself.
