Allelopathic effect of Lantana camara L. (Family: Verbenaceae) on algae, antimicrobial effects, germination and seedling establishment of some agricultural crops have been recognized. The present study was conducted to identify the effect of L. camara on the germination and seedling growth of some...

A recent survey conducted to identify and document aquatic plant diversity of Sri Lanka has resulted in the identification of three exotic plant species, Echinodorus sp. (Alismataceae), Mayaca flutivalis (Myacaceae) and Ludwigia sedioides (Onagraceae) occurring extensively in the natural water...

Mikania micrantha H.B.K. (Asteraceae) is native to tropical America. It is a noxious invasive weed in Southeast Asia, South Asia, and China. The weed grows fast and climbs up on top of trees and shrubs, forms a thick layer and eventually suffocates the support plants underneath. Large areas of...

Parthenium (Parthenium hysterophorus), Chromolaena (Chromolaena odorata) and Lantana (Lantana camara) are major invaded weeds in India. These weeds are reported to have pronounced allelopathic effects and higher nutrient contents in their biomass. The allelopathic potential and manurial value of...

Mimosa pigra L. (Mimosaceae), a noxious semi-aquatic woody plant and once considered to be an important invasive species in the early 1980s has now spread through out Peninsula Malaysia. This happened despite an effort to control the spread through the introduction of two biological control...
