“…This proved that the two types of inoculants had the same ability to the anthracnose incidence. Ibrahim et al (2017) reported that virulence of C. acutatum on chili depend on the isolates and chili varieties. C. acutatum and C. gloeosporioides had capability to infect all of the parts of the chili plant.…”

Response of six chili varieties to anthracnose disease caused by Colletotrichum acutatum and C. gloeosporiodes. Chili is one of the horticultural commodities with high economic value. Chili production is constrained by anthracnose diseases. Losses due to anthracnose can reduce the fruits quality and yields lose. This study aims to determine the resistance of several chili varieties to anthracnose. Genetic material was used six varieties of chili. Ripe chilies were inoculated with two types of Colletotrichum isolates, i.e. C. acutatum and C. gleosporides. The experiment was arranged in a factorial randomized block design with three replications. The first factor were chili varieties: Laris, SSP, Habanero, Cibinong, Ekasari, and Kopay. The second factor was two types of fungal isolates. Observations were made on the incidence and severity of disease due to anthracnose. The results showed that both fungal isolates were effective in causing anthracnose disease in chilies. Habanero was very susceptible to anthracnose. Laris and Ekasari were moderately resistant to anthracnose diseases. These findings are important to develop new Capsicum cultivars that are more adaptive to anthracnose disease.

“…Identifikasi Pengamatan dilakukan pada 3 dan 5 hari setelah inokulasi dengan mengukur luas koloni cendawan patogen. Selanjutnya diamati pula mekanisme kompetisinya dengan melihat perkembangan cendawan antagonis dan patogen dalam memenuhi cawan petri, dan mekanisme paratisme dilakukan berdasarkan berdasarkan perkembangan hifa cendawan antagonis yang mampu melewati dan menutupi koloni cendawan patogen (Nurbailis et al 2015).…”

Trichoderma of coffee roots from Alor: Morphological characteristic and in vitro efficacy to inhibit Colletotrichum, causing Anthracnose Trichoderma is a fungus capable of intimate associations with plant root systems including on coffee plants. This aim of study is to determine the characteristics of Trichoderma morphospecies from coffee roots of Alor origin, East Nusa Tenggara (NTT) and its ability to inhibit the growth of Colletotrichum causing anthracnose disease in-vitro. Root samples of healthy coffee plants were taken from the location of coffee plantations in Alor District, NTT. Isolation of Trichoderma fungi from coffee roots was done by incubating the sterilized coffee roots in a layer of moist filter paper in a Petri dish for seven days. Identification of Trichoderma by observing the characteristics of the colony on the medium of potato dextrose agar (PDA) and microscopic media using microcultures (slide culture). Inhibition of Trichoderma fungi against Colletotrichum was tested by multiple culture methods on PDA media. The results of root incubation in humid conditions showed that there was four morphospecies of Trichoderma fungi, each of which had different characteristic specifications. In vitro antagonism in test on PDA medium, the first three morphospecies against Colletotrichum showed that each Trichoderma could inhibit 70.2%, 65.8%, and 63.3%, respectively, five days after inoculation. This data shows that Trichoderma isolated from coffee roots from Alor has the potential to suppress the growth of anthracnose pathogens.

“…Penyakit antraknosa merupakan penyakit utama pada tanaman cabai. Ibrahim et al (2017) melaporkan sampel buah cabai terinfeksi antraknosa dari Sumatera Utara, Sumatera Barat, Riau, Jawa Barat, Jawa Tengah, dan Jawa Timur disebabkan oleh C. acutatum. Pada beberapa kasus, tanaman yang terinfeksi antraknosa pada saat sebelum dan setelah panen secara bersama-sama dapat menyebabkan kehilangan hasil lebih dari 50%.…”

Activity of Fungal Endophyte Secondary Metabolites against Colletotrichum acutatum on Chili PepperColletotrichum acutatum is one of anthracnose causal agents on chili pepper that has been reported to be predominant species in a some regions of Java Island. Secondary metabolites of endophytic fungi have been reported to have a potency as antifungal agents against plant pathogen. However, its antifungal activity against C. acutatum has not been reported yet. This study was aimed to evaluate the antifungal activity of fungal endophyte secondary metabolite against C. acutatum at in vitro and in vivo assay. In vitro assay was conducted to evaluate antifungal activity of fungal endophyte CBR1D14 isolate culture filtrate (FCBR) and mycelia extract (MCBR) in inhibiting conidial germination of C. acutatum. The results of in vitro assay showed that ethyl acetate extract of FCBR (EA FCBR) had the highest activity in inhibiting C. acutatum conidial germination. Methanol fraction from the partition of EA FCBR (FM FCBR) and from the partition of MCBR ethyl acetate extract (FM MCBR) showed the ability in inhibiting C. acutatum conidial germination. In vivo assay to chili pepper fruit showed that the treatment of FM FCBR (IC95 609.9 µg mL-1) and FM MCBR (IC95 1178.27 µg mL-1) decreased anthracnose disease incidence and lesion diameter. The efficacy rate of FM FCBR and FM MCBR treatments against anthracnose was 36.72 and 48.68%, respectively. Bioautography test was done on silica gel thin layer chromatogram. Methanol fraction of FCBR and MCBR were separated into 3 bioautographic spots respectively (Rf 0.04, 0.07, 0.7 for FM FCBR and Rf 0.06, 0.52, 0.7 for FM MCBR).
