- W3033367085 abstract "<em></em><em>One of the important diseases on chili is anthracnose caused by </em>Colletotrichum capsici<em>. </em>Curcuma<em> extracts and </em><em>their essential oils were known as antifungal, but nonessential compounds have not been widely tested. This study aimed to assay the effectiveness of nonessential compounds of </em>Curcuma longa<em>, </em>C. zedoaria<em>, and </em>C. aeruginosa<em> to </em>C. annuum<em>. This study was conducted in November 2014 until Mei 2015 at Brawijaya University. The nonessential compound was obtained by soaking rhizome of </em>C. longa, C. zedoaria<em>, and </em>C. aeruginosa<em> in methanol, then distilled by</em><em>using rotary vacuum evaporator. Nonessential chemical compunds were identified by using HPLC. Effectiveness evaluation of nonessential compounds from three species of </em>Curcuma<em> was done by in </em>vitro<em> and </em>in vivo<em> test. Tested treatments were three species of </em>Curcuma<em> spp and 6 concentration levels of nonessential compounds (0 ppm, 4 ppm, 6 ppm, 8 ppm, 10 ppm, and</em><em> 12 ppm). The xperiment was performed in Factorial Complete Randomized Design, with 18 treatments combination, and replicated three times. Results of HPLC analysis showed the rhizomes of the three </em>Curcuma<em> species contained curcumin and </em>desmethoxycurcumin<em> in various concentrations. The highest </em><em>level was found in the </em>C. longa<em> extract (13.792 ppm curcumin and 67.156 ppm </em>desmethoxycurcumin<em>). However, in vitro test results showed nonessential compound of </em>C. zedoaria<em> was most effective in inhibiting </em>C. annuum<em> growth. The 10 ppm concentration inhibited 81.53 % of fungal growth. Further, the in vivo test, also indicated the same, it’s most effective in hampering the growth of anthracnose symptoms. Therefore, curcumin and </em>desmethoxycurcumin<em> from three species of </em>Curcuma<em> have potential to be developed as botanical fungicide.</em>" @default.
