Abstract. Nurbailis, Yanti Y, Resti Z, Djamaan A, Rahayu SD. 2023. Consortia of endophytic bacteria for controlling Colletotrichum gloeosporiodes causing anthracnose disease in chili plant. Biodiversitas 24: 3503-3511. Anthracnose disease caused by Colletotrichum gloeosporioides is the main disease in chili plants, which reduces yields by up to 90%. Using a consortium of endophytic bacteria is an alternative way to control the disease at a low cost and is environmentally friendly. The aim of the study was to obtain the best consortium of endophytic bacteria to control anthracnose caused by C. gloeosporioides and improve the growth and yield of chili plants. This research was arranged in an experimental method consisting of two stages, namely (i) compatibility test between endophytic bacterial consisting of 28 species, and (ii) test of the endophytic bacterial consortium ability to control anthracnose in chili using a Completely Randomized Design (CRD) with 14 treatments and provided with 3 replications. All treatments of endophytic bacterial consortium showed the potential to suppress anthracnose disease caused by C. gloeosporioides and improve the growth and yield of chili plants. The best bacterial consortium treatment in suppressing the development of anthracnose disease by C. gloeosporioides and increasing the growth and yield of chili plants was the consortium B. cereus SNE 2.2 + B. cereus TLE 1.1 with dis-ease severity of 0.00%, plant height of 58.33 cm and fruit weight of 208.97 g.

“…Colletotrichum species have been shown to infect plants by spore germination, appressoria development, and hyphal penetration in the host epidermis (Yan et al, 2018). Disease symptoms were found to increase during the rainy season because conidia of Colletotrichum are disseminated onto fresh fruit, resulting in a secondary infection (Suparman et al, 2017). The disease symptoms differ depending on the plant part affected; it causes damage in fruits in particular, appearing as dark, necrotic lesions with concentric acervuli rings, leading to pre-and post-harvest rot (Saxena et al, 2016).…”

Evaluation of Trichoderma atroviride and Trichoderma longibrachiatum as biocontrol agents in controlling red pepper anthracnose in Korea

et al. 2023

Anthracnose disease is a serious threat to red pepper crops in Korea and many other countries, resulting in considerable yield losses. There are now no effective control techniques available except for fungicide sprays, which may directly impact consumers. This study aims to investigate the biological activity of Trichoderma isolates in controlling red pepper anthracnose caused by Colletotrichum acutatum in vitro and in the field. Out of 11 Trichoderma isolates screened for biocontrol agents against three fungal pathogens, including C. acutatum; two effective Trichoderma isolates, T. atroviride ATR697 (ATR697) and T. longibrachiatum LON701 (LON701) were selected for further investigation. Using the overlapping plates experiment, it was discovered that the volatile organic compounds (VOCs) produced by ATR697 strongly inhibited C. acutatum mycelial growth to a larger extent than the isolate LON701. A cellophane membrane experiment has shown that mycelial growth of C. acutatum was inhibited by 36% and 27% when treated with ATR697 and LON701, respectively. Culture filtrates (CFs) of two Trichoderma isolates inhibited the mycelial growth of C. acutatum in vitro. When red peppers were treated with spore suspensions of LON701 and ATR697, the disease severity (%) was 44.1% and 55.8%, respectively, in a curative method; while the disease severity (%) was 5% and 11.6%, in LON701- and ATR697-treated red peppers, respectively, in a preventive method. These results showed the suppression of disease severity (%) was relatively higher in the preventive method than in the curative method. Furthermore, Trichoderma isolates ATR697 and LON701 were resistant to commercial chemical fungicides in vitro, indicating these strains may also be used synergistically with a chemical fungicide (pyraclostrobin) against the growth of C. acutatum. There was no difference in the inhibition rate (%) of the pathogen between the treatment with LON701 alone and LON701+pyraclostrobin. Based on in vitro findings, ATR697 and LON701 played a role in effectively controlling red pepper anthracnose in field conditions, with LON701 treatment resulting in a disease rate of 14% when compared to ATR697, chemical, and non-treated controls. Overall, our study showed the ability of Trichoderma isolates to control red pepper anthracnose and their potential to develop as novel biocontrol agents to replace chemical fungicides for eco-friendly, sustainable agriculture.

“…Anthracnose is a disease that occurs worldwide, caused by various fungal species of the genus Colletotrichum, and has been described as an obstacle to produce sweet and chili peppers in various countries. As the disease onset and development are favored by high temperatures and humidity (RAHMIYAH et al 2018), anthracnose epidemics are problematic in tropical and subtropical regions (RAMPERSAD et al 2016;SAXENA et al 2016). The disease can occur in pre and postharvest (REIS et al 2009;SILVA et al 2019;PEDROSO et al 2020).…”

Anthracnose, caused by a complex of Colletotrichum species, causes severe damage in various crops, including sweet and chili peppers (Capsicum spp.). The present work is an overview of the breeding advances, challenges and limitations to the identification and characterization of genetic resistance and analytical tools employed for the development of Capsicum cultivars in breeding programs aimed at anthracnose resistance. The complexity and variability of the Capsicum-Colletotrichum pathosystem have practical implications for the germplasm resistance assessment protocols and the selection of representative populations of the pathogens. The methods and tools used for phenotypic evaluation must be adjusted to increase the reliability of the data, which in turn, is essential for the identification of unique genotypes able to contribute to the development of cultivars with durable resistance.
