White Cedar has the scientific name Melia azedarach L. and is also commonly known as Persian Lilac, Chinaberry and Umbrella Tree. Dried Chinaberrytree material only moderately reduced weed emergence in a rice paddy, leading researchers to speculate that allelopathic potential of Chinaberrytree could be influenced by soil chemistry and microorganisms .
