Parthenium hysterophorus L. (family Asteraceae) is one of the 10 worst weeds in the world. This weed became the major invasive weed in both arable and grazing lands due to competitiveness and adaptability to different climates and soils. The natural occurrence of phyllody was noticed ~ 10-15% of Parthenium hysterophorus growing wildly along the roadside in Jaunpur, Azamgarh, Gorakhpur, and Varanasi districts of Uttar Pradesh, India, during summer 2010. To test whether Parthenium plants harbor phytoplasma, which may also infect important agricultural crop weeds and cultivated plants in Eastern U.P. India, phyllody symptoms were collected and assessed by polymerase chain reaction (PCR).
