Abstract

The apple farming group is one of the built of Department of Plant Pests and Diseases, Agricultural Faculty, Brawijaya University. In 2019, this departmen received a request from apple farmers in Madiredo Village, Pujon District to held an assistance programs of apple cultivation and environmentally pest control. This is related with the increasing of fruit rot and other diseases which is caused a decrease of apple production especially in Malang Regency. In general, apple farmers still rely on disease control using chemical fungicides which can have a negative impact on the environment and create resistance to pathogenic fungi. Therefore, this research was carried out to explore and study the potential of biological agents in apple production centers in Malang Regency, specifically in Poncokusumo, Pujon, and Batu District on conventional fields and mixed fields. This research was held observationally through fields surveys and farmer interviews, took soil samples and disease samples then then isolating, identifying and testing for antagonism at laboratory. Based on interviews and observation of symptomology, two dominant diseases were found, namely fruit rot disease (Gloeosporium sp.) and marsonina leaf spot disease (Marssonina coronaria). The results of exploration of the rhizospheric apple plants obtained isolates on conventional fields in Kec. Pujon has the highest abundance of fungal colonies compared to other regions. Based on the results of the antagonism test for pathogenic fungi and biological agents, it was found that the isolate codes KH.C, KK.A, JK.B, JK.J, and BK.B had the highest percentage of inhibition or the most effective in controlling the pathogen Gloeosporium sp. So in the next, the species can be identified molecularly.

Abstract

Rice, as a staple food, is widely produced across Indonesia. However, bacterial leaf blight (BLB) in rice is caused by Xanthomonas oryzae pv. oryzae (Xoo) has been reported to cause significant crop yield losses. The continuous use of chemical bactericides to control BLB is not environmentally sustainable. This study investigated the potential of the Binahong plant as a botanical pesticide to suppress the growth of Xoo bacteria. Binahong is readily available in Indonesia and can be propagated generatively and vegetatively. The research employed a Completely Randomized Design (CRD) experimental method to evaluate the effectiveness of Binahong leaf extract against Xoo pathogens in vitro at various concentrations (0.5%, 1%, 1.5%, 2%) alongside positive and negative controls. In-vivo observations were made on several parameters: seed germination percentage, disease incidence, incubation period, and plant length. Data analysis revealed that Binahong leaf extract inhibited the growth of Xoo bacterial colonies in vitro at all tested concentrations (0.5% to 2%). Furthermore, soaking rice seeds in Binahong leaf extract was effective in vivo at all concentrations, demonstrating significant differences compared to the negative control and no significant differences compared to the positive control.

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.

Abstract

The cultivation of potatoes in Indonesia faces challenges, particularly a decline in production attributed to the devastating impact of late blight caused by the fungus P. infestans. Traditional control methods involve the frequent use of chemical pesticides, which pose environmental and health risks. To address this, the research aimed to assess the efficacy of biofungicide containing Trichoderma sp. as a biological agent in controlling late blight on potatoes. The study, conducted in Sumberbrantas Village, Bumiaji District, Batu City, East Java, and the plant disease laboratory at Brawijaya University from January to April 2023, employed both in vivo and in vitro experiments. A Randomized Block Design (RBD) was used for in vivo research, while a Completely Randomized Design (CRD) was employed for in vitro studies, each comprising five concentration treatments with five repetitions. Parameters such as disease intensity, efficacy level, potato production, and biofungicide inhibition were observed. Analysis of variance and the Tukey Honestly Significant Difference (HSD) test were applied to the data and processed using Microsoft Excel. The results indicated that biofungicide with Trichoderma sp. concentrations of 6 ml/l, 4.5 ml/l, 3 ml/l, and 1.5 ml/l effectively reduced the intensity of late blight on potatoes, with efficacy levels exceeding 50%. The highest potato production occurred with a concentration of 6 ml/l, yielding 15.44 tons/ha, followed by 14.67 tons/ha for the 4.5 ml/l concentration. The biofungicide with a concentration of 6 ml/l exhibited the lowest disease intensity at 14.28% and the highest efficacy at 83.08%. Inhibition tests demonstrated that concentrations of 6 ml/l and 4.5 ml were highly effective, inhibiting P. infestans growth by an average of 62.04% and 59.90%, respectively. These findings highlight the potential of biofungicide with Trichoderma sp. in managing late blight on potatoes, providing a sustainable and environmentally friendly alternative to chemical pesticides.

Abstract

The Role of Trichoderma spp. as a Biocontrol Agent of Damping Off Disease and Soybean Biostimulant   Domestic demand for soybeans in Indonesia continues to increase each year, yet the average production has declined. To meet national needs, the government must even import soybeans. One of the causes of low soybean production is damage from plant pests and diseases, particularly damping-off caused by Sclerotium rolfsii, which can lead to total plant death under severe infection. One promising, environmentally friendly, and cost-effective approach to disease management is the use of biological control agents such as Trichoderma spp., which function not only as biocontrol agents but also as biostimulants. This research was conducted at the Plant Pest and Disease Laboratory, Faculty of Agriculture Brawijaya University and Central Laboratory of BALITKABI for in vitro experiments and in vivo study located at a greenhouse of Agriculture Experimental Land Brawijaya University, Jatimulyo, Lowokwaru, Malang. A completely randomized design was used with five treatments and five replications. Applications of Trichoderma harzianum and T. asperellum, either individually or in combination, successfully reduced the incidence and severity of damping-off disease by 14% to 26.6% under field conditions. These treatments also increased the total phenolic content of the plants, indicating enhanced resistance, thus supporting the role of Trichoderma as an effective biocontrol agent. In addition, the combined application of Trichoderma species significantly increased the number of soybean leaves, indicating a biostimulant effect.
