“…These necrotic spots cause defoliation of the crop's leaves. The initial signs on the stem according to Manda et al (2020) were brown patches, which led to necrosis of twigs and, in extreme cases, plant dieback. On the necrotic surface of the twigs, acervuli are also discovered.…”

Abstract. Hodiyah I, Suryaman M, Hartini E, Juhaeni AH, Laksana BY, Aisyah, Benatar GV. 2024. Diversity of morphology, pathogenicity, and host range of Colletotrichum spp. associated with chili anthracnose in East Priangan, Indonesia. Biodiversitas 25: 533-541. Chilies, in Indonesia, encounter several obstacles that impact their production and quality. Chili production in Indonesia has seen oscillations, partly due to the detrimental effects of anthracnose disease produced by the Colletotrichum fungus species. The disease has a detrimental effect on the quality of fruit, foliage, and plants, resulting in unpredictable yields and significant losses, especially during the rainy season. Although chilies has important economic value in Indonesia, more comprehensive studies are needed on chili anthracnose in the East Priangan area, West Java Province, Indonesia. The purpose of this research was to specifically investigate the incidence of chili anthracnose and to isolate the pathogen responsible for the disease. Colletotrichum isolates were subjected to morphological characterization and pathogenicity tests to assess their virulence. In addition, the research evaluated the possible spectrum of hosts that these isolates might infect in order to determine their effect on other commodities. In East Priangan, chili anthracnose disease was found everywhere with severe disease incidence. Highest disease incidence was recorded in Garut District (100%), and the lowest was in Ciamis District (50.5%). The isolation results showed that a total of 18 diverse isolates were isolated from three chilli species at different altitudes. Macroscopic and microscopic characteristics showed variability, with growth rates ranged from 0.24 to 3.7 mm per day and diverse conidia shapes and sizes. The pathogenicity test confirmed the virulence of 17 isolates, causing symptoms with concave circular wound diameters ranged from 6.88 to 61.08 mm. Host range results demonstrated the pathogenicity of specific isolates to tomatoes, strawberries, and grapes, with strawberries exhibited higher severity levels (28.05 to 56.38 mm lesions). Gaining comprehensive knowledge about the variety and widespread occurrence of chili anthracnose in this particular area is essential for formulating effective measures to minimize its adverse effects on chili cultivation and guarantee the long-term viability of the chili sector in Indonesia. To our knowledge, this is the first study of chili anthracnose in the East Priangan region.

“…Meanwhile, a common disease was Anthracnose (Table 5). Those three kinds are the ultimate pests and diseases quite often attacking the chili plant, cause yield losses and degrade the chili yield [16][17] [18]. The respondents could answer more than one answer…”

Chili has become a high-value economic commodity in Indonesia. Indonesian chili consumption is increasing every year. In order to fulfill the demand, chili commonly is planted on fertile land. Meanwhile, Indonesia has a vast less fertile land, such as the acid dry land that has not been utilized for a long time. This land can be utilized to plant chili. However, there are many challenges to be faced that need to be solved. The study aims to identify farmers' challenges on chili farming an acid dry land, viewed from social-economic aspects, natural conditions, biology, and land. The study was conducted from April to October 2016 in Pasir Madang, Sukajaya sub-district, Bogor, Indonesia. About 49 chili farmers were involved in the study. Data were analyzed descriptively. The results of the study showed that the farmers planted chili because it was profitable. Area for planting chili commonly less fertile/infertile. To solve the problem, farmers used manure and chemical fertilizers. Meanwhile, challenges faced by the chili farmers were pest and disease attacks. Other obstacles were capital, farmers' knowledge on chili cultivation, and choosing effective and efficient fungicides and insecticides to control the chili pests and diseases.

“…Not only does microbial contamination occur, but Anthracnose, caused by the fungus Colletotrichum gloeosporioides , has also been considered a major problem in chili [ 7 , 8 ]. This disease leads to a small yield of chili production due to low seed germination [ 9 ] and loss as food waste. Furthermore, this disease also resulted in the low quality of chili as reflected by its poor appearance and low capsaicin and oleoresin content [ 10 ].…”

Plasma activated water (PAW) generated from pinhole plasma jet using gas mixtures of argon (Ar) and 2% oxygen (O2) was evaluated for pesticide degradation and microorganism decontamination (i.e., Escherichia coli and Colletotrichum gloeosporioides) in chili (Capsicum annuum L.). A flow rate of 10 L/min produced the highest concentration of hydrogen peroxide (H2O2) at 369 mg/L. Results showed that PAW treatment for 30 min and 60 min effectively degrades carbendazim and chlorpyrifos by about 57% and 54% in solution, respectively. In chili, carbendazim and chlorpyrifos were also decreased, to a major extent, by 80% and 65% after PAW treatment for 30 min and 60 min, respectively. E. coli populations were reduced by 1.18 Log CFU/mL and 2.8 Log CFU/g with PAW treatment for 60 min in suspension and chili, respectively. Moreover, 100% of inhibition of fungal spore germination was achieved with PAW treatment. Additionally, PAW treatment demonstrated significantly higher efficiency (p < 0.05) in controlling Anthracnose in chili by about 83% compared to other treatments.
