Extract

Pluchea lanceolata (DC.) C. B. Clarke # PLULA is an aggressive, pernicious, rhizomatous evergreen weed in the Asteraceae. In other literature, P. lanceolata Oliv. & Hiern has also been mentioned (Anonymous 1992, pp. 731 and 1147). With heavy root branches and dense subterranean parts, P. lanceolata is a common weed of sandy and saline tracts of the dry plains of the northwestern parts of India (Dakshini and Sabina 1981; Inderjit 1993; Rice 1995). It also occurs in North Africa, Afghanistan, and Pakistan (Nasir and Ali 1972; Oliver 1885). In India, it occurs both in cultivated and uncultivated areas. It causes considerable damage to winter and summer season crops. The control measures through conventional methods such as deep plowing, burning of aboveground parts, and herbicides are found to be unsuccessful. This rapidly spreading perennial weed apparently cannot be used for forage because of its disagreeable bitter taste (Anonymous 1976). Allelopathy has been reported as a probable cause of P. lanceolata interference (Inderjit and Dakshini 1990, 1992b, 1994a, 1994b, 1996a, 1996b; Inderjit et al. 1996).
