Intention of this research is to test the ability of some concentration of mengkudu fruits extract in controling disease anthracnose on fruit of chilli. Research conducted experimentally use the Complete Random Device ( RAL) by 5 [is] treatment and 4 restating. Its treatment is concentration of the following mengkudu fruits extract: MO = ( 0 %), Ml = ( 5 %), M2 = ( 10 %), M3 = ( 15 %), and M4 = ( 20 %). Result of research indicate that the gift [ofj some concentration of mengkudu fruits extract on chilli fruit give the different influence in controling disease anthracnose on fruit of chilli. Concentration of better mengkudu fruits extract in controling attack of disease anthracnose on chilli fruit is 20% which can give the effect of resistance of growth of larger ones colony, longer incubation period and smaller attack intensity.enUR e-Research
