“…Siddique et al 2018 reported that highest benefit cost ratio of 1.89 was obtained from Carbendazim in the management of foot and root rot of brinjal caused by S. rolfsii and treatment with T. harzianum gave a benefit cost ratio of 1.34 respectively. Daunde et al (2020) also reported that Carbendazim (50WP), T. harzianum and T. viride gave a cost benefit ratio of 1:2.79, 1:2.38 and 1:2.32 in the management of collar rot of chilli caused by S. rolfsii. The present findings are also in conformity with the findings of Sunkad (2012) and Jadon et al (2017).…”

“…Most of the diseases, collar rot or pepper rot, due to S. rolfsii occur in almost all pepper growing regions. It reasons a decrease in yield to 16-80% (Daunde et al 2018). The pathogen is found to cause various symptoms like crown rot, root rot, stem rot, rotting of pseudo bulbs, wilt, and the gradual death of the plants, etc.…”

Abstract. Yadav D, Adhikari A, Dhuingana B, Gurung H, Khatri N, Pandit S. 2022. In-vitro efficacy of Trichoderma isolates on Sclerotium rolfsii causing collar rot of chili. Asian J Agric 6: 97-102. The experiment was conducted in the Nepal polytechnic institute plant pathology laboratory to study the in-vitro efficacy of Trichoderma isolates on Sclerotium rolfsii Sacc. collar of chili, Bharatpur, Chitwan, Nepal by dual culture technique. The experiment was carried out in a completely randomized design (CRD) with four replications. The Trichoderma isolates, namely Kapilvastu isolate, Kavre isolates, Salyan isolates, Lalitpur isolates, and Taplejung isolates, were used in the experiment. The mycelium growth was measured at 2 DAI, 4 DAI, 6 DAI, 8 DAI, and 10 DAI. Also, the number of sclerotia, days to sclerotia, and width of the browning area at the interception region of interception were measured in 10 DAI. All the Trichoderma isolates significantly affect mycelium growth and the number of sclerotia formed. Among all the Trichoderma isolates, Kavre isolates show a good result with (74.44%) followed by Salyan isolates (74.22%) and Lalitpur isolates (73.55%) inhibition in the mycelium growth and several sclerotia (9.6~10) also formed. The lowest number of sclerotia was observed in Salyan isolates, which was three days, followed by Kapilvastu isolate, i.e., 20 days. The antagonist Kavre isolate can be used as a bio-control agent against S. rolfsii of chili in Nepal.

“…Chilli (Capsicum annuum L.) is an important spicy plant because of its widespread consumption, high vitamin content and high profitability in developed and developing countries (Oo and Oh, 2016). Chilli production is invariably affected by fungi, bacteria, viruses, nematodes and insects, leading to severe crop and fruit damage every year (Hussain and Abid, 2011;Daunde et al, 2018). Anthracnose, with its causal agent Colletotrichum spp., is the most important disease in chilli (Oanh et al, 2004;Than et al, 2008b).…”

“…These biotic elicitors could trigger many defense mechanisms, including the amount of SA, hypersensitive response (HR), callose, reactive oxygen species, defenserelated genes, phenolic compounds, phytoalexins and defense enzymes. Consequently, defense activities could reinforce cell walls and kill phytopathogens when the plants are infected (Park et al, 2016;Daunde et al, 2018). The main defense components of disease resistance are SA and phenolic compounds.…”

Importance of the work: Chilli cultivation in Thailand has a problem with anthracnose. Biological control is used to reduce such problems. Objectives: To assess the biocontrol efficacy of Bacillus subtilis against Colletotrichum spp. causing anthracnose in chilli. Materials & Methods:The antagonistic effects were evaluated in vitro of B. subtilis on Colletotrichum spp. and the associated effects on chilli seed growth. In addition, the amount of salicylic acid (SA) and phenolic compounds in chilli plants and B. subtilis efficacy on anthracnose severity of leaves and fruits were assessed under net-house conditions. Results: The results showed that the antagonistic percentage of B. subtilis was approximately 55% and it did not affect germination rates, shoot height or the root length of chilli seedlings. The Bacillus treatment reduction levels of anthracnose severity on chilli leaves and fruits were 86-100% and 49-74%, respectively. In the chilli plants, B. subtilis induced phenolic compound levels to approximately 22 mg per 100 g fresh weight (FW) and 19 mg per 100 g FW in leaves and fruits, respectively. Similarly, the amount of SA increased to 62-65 µg/g FW and 14-17 µg/g FW in chilli leaves and fruits, respectively. Main finding: Application of B. subtilis inhibited anthracnose disease in chilli and could be a safe alternative to harmful chemical usage.
