Abstract
This work has objective to test biological performance of Alleopathy extract between Chromolaena
odorata and Ruellia tuberosa to inhibit germination, and growth of Echinochloa colona. In parts of
methodology, we have separated into 2 sections which are extraction Alleopathy from Chromolaena
odorata ,and Ruellia tuberosa ,and testing efficiency of inhibition germination and growth of
Echinochloa colona. From the experiment, we have encountered tertiary substance 4 groups which are
Alkaloid, Phenolic, Flavonoid, and Terpenoid of Alleopathy. The Chromolaena odorata extraction has
better efficiency than Ruellia tuberosa extraction. Chromolaena odorata extraction at concentration
2000, 4000, and 6000 ppm are able to inhibit growth of Echinochloa colona for 38.49%, 58.47%, and
70.49% respectively. Moreover, injection of extraction concentration 6000 ppm into the rice farm. We
find both extract do not influence to the germination, and growth of rice when compare with control
condition. Therefore, Chromolaena odorata, and Ruellia tuberosa extract are able to inhibit
Echinochloa colona, and have no side effect to the rice.

Keywords: Alleopathy, Chromolaena odorata, Ruellia tuberosa, and Echinochl
