IMPACTS
Is a fire hazard and poses a significant threat to native flora. It is a serious pest of crops and pastures throughout the tropics (Holm et al., 1979). Infestations of M. pudica can lead to a 10–70% reduction in upland rice yields in Kerala, India (Joseph and Bridgit, 1993). It is also considered a serious weed of sugarcane, sorghum, maize, soybean (Holm et al., 1977), tomatoes, pineapples, cotton (Lee Soo Ann, 1976; Waterhouse and Norris, 1987), rubber, tea, coffee, coconut, oil palm, banana, mango, papaya, citrus and even Acacia mangium plantations in Indonesia (Nazif, 1993). Mimosa also invades pasture and can be toxic to livestock. It is suspected of poisoning cattle in Papua New Guinea (Henty and Pritchard, 1975) and has caused stunted growth in chickens in Indonesia (Kostermans et al., 1987).
