Abstract

Anthracnose disease (Colletotrichum gloeosporioides) is one of the important diseases in shallots. Generally, farmers use synthetic fungicides. Thus, Siam weed (Chromolaena odorata) leaf extract can be used to reduce it because it has antifungal compounds. This study aimed to examine the effect of siam weed leaf extract on the growth of C. gloeosporioides and its antifungal compounds. This research used a completely randomized design (CRD). It would be continued with the SRD test at the 5% level if the result was significantly different. Treatment consisted of 0, 2, 4, 6, 8, and 10% Siam weed leaf extract with four replications. Bioactive compounds in siam weed leaves were tested by the UPT Herbal Materia Medica Batu Laboratory and Chem-Mix Pratama Laboratory, Yogyakarta. Probit analysis was also used to obtain the LC50 value. The results showed that 10% concentration was the most effective treatment because it produced a fungicidal effect on C. gloeosporioides. However, a 2.09% concentration of siam weed leaf extract was able to cause 50% of C. gloeosporioides' mortality. In addition, siam weed leaf extract contains antifungal compounds, such as tannins, phenols, flavonoids, alkaloids, and saponins.

Abstract

Red chili (Capsici annum L.) is a significant horticultural commodity widely consumed in Indonesia. From 2016 to 2020, red chili production consistently increased, reaching 1,264,190 tons in 2020. Despite this growth, certain regions still face production shortfalls relative to consumption needs. A major challenge in red chili cultivation is the Tobacco Mosaic Virus (TMV), which remains difficult to control as no pesticides currently target plant viruses directly. This study investigated the impact of guava leaf extract (Psidium guajava L.) on the incubation period, severity of TMV infection, and growth parameters in red chili plants. The experiment utilized a complete randomized design comprising six treatments with four replications, each involving two plants. The results indicate that four applications of guava leaf extract extended the TMV incubation period to 19.25 days post-inoculation and reduced attack intensity by 4.93%. Additionally, this treatment enhanced plant growth, evidenced by increased plant height and leaf number, and was the only treatment classified as resistant compared to other tested methods.
