Impacts and Management Strategies of Parthenium hysterophorus L. in Agriculture

Abstract

Parthenium hysterophorus may have migrated to India in 1910 on germplasm from diseased cereals, but it wasn't discovered until 1956. Since its discovery in 1955, weed has spread to about 42 million acres of land. The individual weed can yield 10,000 to 15,000 viable seeds due to its extraordinary fecundity. Four weeks after germination, plants are ready to blossom and produce seeds. This important global weed is also a significant risk to biodiversity and causes crucial health problems for humans and animals, including dermatitis, asthma and bronchitis. Chemical control must be managed appropriately. When plants are young and haven't set seed, weed should be pulled. However, merely limiting its expansion is not enough to get rid of it; instead, it can be managed through utilizing it for different purpose.
