Abstract : Results are given of a 1986 survey of M. cordata in South Andaman island, India. Among natural sites, highest coverage of the weed was recorded along natural water courses (45.5 t FW/ha). Recently cleared forest areas, roadside trees and shrubs were also heavily infested by the weed. In plantation crops the highest incidence of M. cordata (16 t FW/ha) occurred in Areca catechu, followed by red oil palm [Elaeis guineensis] (14.8 t) and coconuts (13 t). Infestations of >10 t FW/ha were recorded in mangoes, Pouteria sapota, Phyllanthus emblica, bananas, pineapples and pawpaws, though guavas were less affected. Sugarcane, especially the ratoon crop, was also severely infested (20.3 t FW/ha.).
