Cayenne pepper (Capsicum frutescens L.) is a horticultural crop that is widely cultivated in Indonesia and has high economic value. However, it is not uncommon for the cultivation process to encounter several obstacles, one of which is caused by the Tobacco Mosaic Virus (TMV). One of the actions that can be taken to control this disease is to use induction agents derived from plant extracts. The plants that can be used as inducers are cherry plants (Muntingia calabura). However, research on the use of cherry leaf extract is rarely applied, especially against the TMV virus. Thus, this research needs to be conducted to determine the effect of cherry leaf extract on TMV attack on cayenne pepper plants. The study used a completely randomized design (CRD) in vivo with 6 treatments and 4 replications. The treatment given was cherry leaf extract with different application frequencies at a concentration of 5%. Parameters observed included the disease incubation period, disease intensity, plant growth, and assessment of plant resistance. The results showed that applying cherry leaf extract with an application frequency of 4 times extended the incubation period of TMV and reduced the intensity of TMV disease, with values of 17.88 days after inoculation and 11.20%, respectively. This treatment resulted in a plant resistance category of "resistant." Additionally, the application of cherry leaf extract 4 times also had a positive effect on plant growth, specifically plant height and number of leaves.

Lime is popular in Indonesia as an alternative treatment for cough and sore throat. Global production declined by 316,000 ton in 2021-2023 due to Citrus Tristeza Virus (CTV) attack, which is detrimental to citrus farmers. Effective preventive controls to suppress CTV attack include planting resistant varieties, insect vector control, cross-protection, and the use of Plant Growth Promoting Rhizobacteria (PGPR) or other beneficial microbes. This study aims to determine the effect of PGPR on the incubation period, intensity of CTV attack, chlorophyll content, and growth of lime seedlings. This research was conducted using a completely randomized design (CRD) with 8 treatments and 5 replications. The methods used were PGPR application and CTV inoculation on lime seedlings. The results showed that the application of PGPR Bacillus subtilis, Pseudomonas fluorescens, Azotobacter sp., and their combination was able to slow down the incubation period of CTV, suppress the intensity of CTV attack, and maintain the chlorophyll content of plant leaves due to CTV attack. However, the use of PGPR in this study has not been able to increase the growth of lime seedlings. Single PGPR has the same level of efficiency as the combination in suppressing the intensity of CTV attack.

Shallot Yellow Stripe Virus (SYSV) is one of the economically important viruses of shallot. The incidence of SYSV infection can reach 66%-100%. The high level of SYSV infection on shallot is also due to the lack of resistance varieties to SYSV. This study aimed to determine the resistance of five varieties of shallot and the effect of SYSV infection on shallot production. The study used a completely randomized experimental design (CRD) using five shallot varieties as the treatment with four replication for each treatment. The shallot varieties were Bauji, Thailand, Bima Brebes, Tuk tuk (V4), Trisula (V5), and control. Each experimental unit consisted of 10 plants. The evaluation results showed that the Tuk-tuk variety was categorized as resistant, the Trisula variety as tolerant, and the Bauji, Thailand, and Bima Brebes varieties were categorized as susceptible. The shallot growth and production indicate that SYSV infection causes interference in the plant development process.

Purple blotch caused by Alternaria porri is the primary disease in shallots, causing yield losses of 30-100%. The use of endophytic fungi as biocontrol agents has several advantages, including adaptability to host plants, selective targeting of pathogenic fungal cell walls without harming plant cells, and environmental friendliness. This study aims to select endophytic fungi producing hydrolytic enzymes with the highest inhibitory effect against A. porri. Endophytic fungi were isolated from the Batu Ijo local variety of shallots in Dau District, Malang, then evaluated for antagonism and for their ability to produce hydrolytic enzymes. This study obtained 42 isolates, consisting of 25 fungi and 17 yeasts. The endophytic fungi with the highest inhibitory activity were identified as Trichoderma asperellum (71.4%) and Pichia onychis (70.04%). T. asperellum produced cellulase at concentrations of 16.78 µg/ml and chitinase at 3.85 µg/ml, while P. onychis produced cellulase at concentrations of 11.47 µg/ml and chitinase at 1.56 µg/ml. Microscopic observation of A. porri hyphae showed that both endophytic fungi caused lysis with hyphal fragmentation, discoloration, and deformation. The endophytic fungi T. asperellum and P. onychis were proven to inhibit A. porri in vitro through their ability to produce hydrolytic enzymes that caused A. porri hyphal lysis.

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.
