“…Similar study made by Dasgupta et al [33], Shamsi and Chawdhary [34], Shehab et al [35] and Bashir et al [36] wherein they evaluated antifungal efficacy of D.metel and J.carcus have proven that the D. metel and J. carcus have strong potential to inhibit the plant fungal pathogens. The higher the concentration of the extract, the higher percentage of mycelial inhibition.…”

One of the major fungal disease of rice that farmers are facing today were rice blast and sheath blight. These diseases cause drastic decrease in the productivity and become a problem in related to the consumption. The main objective of this study is to determine the antifungal activity of Datura metel, Jatropha carcus and Ruellia tuberosa ethanolic leaf extract against the isolated pathogen causing sheath blight and rice blast disease of rice. This study employed experimental research method with completely randomized design wherein sheath blight isolates were tested into three different concentrations (25%, 50% and 100%) of the three plant extracts while rice blast isolates were tested in 100% concentration of the three plant extracts. The food poisoned technique assay was used to access the antifungal activity of different three ethanolic extract and was done with three replications. The results showed that the ethanolic leaf extract of D. metel and J. carcus has the highest antifungal activity at 100% concentration against isolated pathogen causing sheath blight having98.611 ± 1.589% and 98.588 ± 1.589 of mycelial inhibition, respectively. Whereas, J.carcus and R.tuberosa has highest antifungal property against rice blast having 97.436 ± 0.555% and 97.115 ± 0.96% respectively. The three plant extracts exhibited high percentage of mycelial inhibition compared to mancozeb. Therefore, the extracts from these three plants have an active potential to inhibit the growth of fungus and can be used as bio fungicide to control infection of rice blast and sheath blight in rice. Since these bio fungicides came from plants, the negative effect for the environment and other organisms will be inhibited and can also support the goal of the government in finding on how to delimit the use of chemical fungicides. To assert the effectiveness on the actual field management of plant health, in vivo trials are recommended.

“…The human need for rice always increases from year to year in line with the increase in population. Sheath rot disease possible to become an obstacle in efforts to increase rice productivity (Garcia et al 2003;Shamsi and Chowdhury 2016). The main pathogens associated with this disease in some countries are fungal pathogens such as Sarocladium oryzae and Fusarium spp.…”

Abstract. Pramunadipta S, Widiastuti A, Wibowo A, Suga H, Priyatmojo A. 2020. Short Communication: Sarocladium oryzae associated with sheath rot disease of rice in Indonesia. Biodiversitas 21: 1243-1249. One of the obstacles in increasing rice production is the presence of sheath rot pathogen infection, which causes changes in color on the rice sheath to brown or reddish-brown, sometimes does not produce rice grain. The major fungal pathogens that cause sheath rot disease are Sarocladium oryzae and Fusarium spp. The loss of rice yields reaches 85%. The disease found in six provinces, some of which are the largest rice-producing centers in Indonesia. A total of twenty-four Sarocladium sp. were isolated from leaf sheath symptom on potato dextrose agar and water agar medium. Sheath rot pathogen identification based on molecular method was performed using internal transcribed spacer (ITS) rDNA gene sequencing. Necrosis occurs after artificial inoculation in Ciherang rice variety was observed and showed that all isolates were pathogenic. Morphological characterization of the isolates identified them as Sarocladium sp. Molecular identification showed that six representatives isolates belonging to S. oryzae. These findings are important information about the fungal pathogen that causes sheath rot disease in Indonesia, and in studies for formulating control measures of the pathogen in the future to prevent the disease epidemic on rice. This is the first report about the existence of sheath rot disease, morphological characterization and molecular identification of S. oryzae in various rice fields in Indonesia.
