Invasion by alien perennial weed Mikania micrantha has created a serious problems in Southeast Asia. This climbing vine possesses very fast growth rate and could multiply from seed and vegetative parts. It climbs on other plants, create a dense cover and block sunlight thereby damage or kill the other plant. It compete for water, soil nutrient and release allele-chemicals inhibiting growth of plants. The weed creates economic loss to plantation, horticultural crops, displaces and kills native vegetation. It is designated as one of the worst invasive plants of the world. M. micrantha is native to Central and South America and is a harmless plant in its native range. It was widely distributed by man to tropical areas of Africa, Asia, Australia and many different countries. The growth of the weed depends on availability of sunlight and soil moisture. M. Micrantha flowers during cool dry season and produces large number of viable seeds. The seed losses its viability with time. Tenperature, light, soil moisture content effect the germination of seed and the seed may persist for about seven years in soil seed bank. The vegetative reproduction of the weed occurs through stem sections and its success depends upon maturity, length and orientation of the stem sections in soil as well as soil moisture content.
