Abstract

Tomato plants (L. esculentum Mill.) are vegetable crops. Tomato production in South Kalimantan is very low due to the attack of a plant disease, namely the yellow curly virus. Caused by the presence of the vector B. tabaci, control usually carried out by farmers is only controlling the vector with insecticides, not to control the virus. This control has negative impacts. Good control and has been widely used is biological control. Which utilizes microorganisms in tomato plants to induce resistance to yellow curly virus infection. In this study, a completely randomized design (CRD) was designed with one factor. The administration of Bacillus spp. derived from bamboo plant roots, elephant grass roots and chili roots was the factor tested. There were 5 treatments and 4 replications, The results of this study showed that the administration of Bacillus spp. derived from bamboo plant roots, elephant grass roots and chili roots, was able to induce tomato plant resistance to yellow curly virus infection. The lowest percentage of yellow curly virus attack intensity with an average (10.54%) was the tomato plants treated with Bacillus spp. derived from elephant grass roots. The average attack intensity of yellow curly virus on untreated and inoculated plants was 32.63%. The administration of Bacillus spp. from bamboo roots (T2), elephant grass roots (T3), and chili roots (T4) was shown to induce tomato plant resistance to yellow curly virus infection.

Abstract

There are many problems and negative impacts caused by insects on chili plants (Capsicum annum L.), so one alternative environmentally friendly control method is to use insect traps, one of the traps that can be used is the yellow trap. The aim of this research is to find out how effective yellow traps are against pests in red chili plantations. This method uses a completely randomized design (CRD) with one factor consisting of four treatments (T1 30 cm, T2 60 cm, T3 90 cm and T4 120 cm), which was repeated 6 times. The results of this study showed that all yellow trap treatments showed that the treatment in the first to sixth weeks had no real effect on trap setting and tended to decrease the number of catches. It was found that the percentage of insect intensity in the observations showed that the highest percentage figure for the T3 treatment was 3.81%, while the lowest percentage figure for the T1 treatment was 3.28%.

Abstract

Celery (Apium graveolens L.) is a leafy vegetable that plays a very important role and has significant export value. In terms of popularity and economic value, celery ranks second after lettuce among spice plants. In South Kalimantan, celery is widely cultivated, but there are serious obstacles faced by farmers, namely the attack of root knot nematodes (Melodogyne spp.) whose population is quite high. Celery plants infected with Meloidogyne spp. usually shows symptoms such as chlorosis on the leaves, stunted growth, wilted leaves, and a small number of roots. In severe conditions, the plant may die. Therefore, the search for environmentally friendly alternatives for pest control is very important. The aim of this research is to reduce dependence on chemical pesticides which can damage agricultural ecosystems. One alternative that can be considered in controlling pests is the use of vegetable pesticides derived from jackfruit leaves (Artocarpus heterophyllus Lamk). This research aims to test the effectiveness of jackfruit leaf powder in dealing with attacks by root knot nematodes (Meloidogyne spp.) on celery plants which is the main focus of this research. This research was carried out by applying the Completely Randomized Design (CRD) method, which aims to obtain accurate and reliable data regarding the impact of the attack which involves one factor, namely treatment using 500 Meloidogyne spp eggs. as a control and four other treatments with jackfruit leaf powder: 500 Meloidogyne spp. + 25 grams of jackfruit leaf powder (P1), 500 Meloidogyne spp eggs. + 50 grams of jackfruit leaf powder (P2), 500 Meloidogyne spp eggs. + 75 grams of jackfruit leaf powder (P3), as well as 500 Meloidogyne spp eggs. + 100 grams of jackfruit leaf powder (P4). The results of the research showed that treatment with 100 grams of jackfruit leaf powder (P4) was able to reduce the severity of the disease and the average number of root knot nematode populations. The highest disease severity was recorded in control plants (K0), namely 38.80%, while the lowest percentage was found in the treatment (P4) which only reached 12.50%. The highest root knot nematode population was observed in treatment (P1) with 427.25 individuals, while the lowest population was recorded in treatment (P4) with 199,875 individuals.

Abstract

Entomopathogens are microorganisms that can cause disease in insects. Entomopathogenic fungi are one type of bioinsecticide that can kill insects by infecting them through the skin, digestive tract, spiracles and other holes. This research aims to identify entomopathogenic fungi from around oil palm plants. The method used in this research began with a survey and purposive sampling of soil samples taken at the oil palm plantation of PT Mulia Agro Permai Timur Sampit, Central Kalimantan. Samples were taken at five different points, one sample was obtained at each point at a depth of 15-20 cm. From the isolation results, five types of isolates were obtained, namely the fungi Penicillium spp., Mucor spp., Trichoderma spp., Metarhizium spp., and Beauveria spp. From the Koch Postulate test using Hong Kong caterpillar larvae (Tenebrio molitor) as test larvae which were inoculated with entomopathogenic fungi. The results showed that the five fungus isolates were able to cause death in the test larvae with different death times for each isolate.

Abstract

This study aims to determine the effect of Cyperus rotundus tuber extract on mortality and final germination of seeds of the weed Neptunia oleracea. The research was carried out using a Completely Randomized Design (CRD) consisting of five concentration treatments, namely 0% (control), 15%, 30%, 45% and 60%, each of which was repeated four times. Parameters observed included mortality rate, final germination and germination length. The results of the study showed that administration of nut tuber extract (C. rotundus) did not have a significant effect on mortality or final germination of seeds of the weed N. oleracea. However, there is a tendency that the higher the concentration of the extract given, the greater the percentage of inhibition that occurs. This shows the potential for allelopathic effects which need to be explored further through research with different concentrations and application methods.

Abstract

Callosobruchus chinensis L. (Coleoptera: Bruchidae) is a major storage pest of legumes that reduces seed quality, germination capacity, and causes yield losses of up to 30–50% during storage. Control strategies have generally relied on synthetic chemical insecticides, which may lead to resistance, hazardous residues, and adverse impacts on health and the environment. Therefore, botanical insecticides are considered a safer and more sustainable alternative. This review article was prepared through a systematic literature study by searching scientific publications from Google Scholar and Google Books using the keywords “botanical insecticide,” “plant extract,” “essential oil,” “pulse beetle,” and Callosobruchus chinensis. The findings indicate that several plants such as Neem (Azadirachta indica), Black Pepper (Piper nigrum), Custard Apple (Annona squamosa), Sweet Flag (Acorus calamus), Tuba Root (Derris elliptica), and Mexican Sunflower (Tithonia diversifolia) show great potential as botanical insecticides. Their active compounds, including azadirachtin, piperine, annonacin, β-asarone, rotenone, as well as alkaloids and flavonoids, act through multiple mechanisms, such as contact poison, stomach poison, antifeedant, repellent, and sterilant agents, effectively suppressing pest populations. The advantages of botanical insecticides include biodegradability, environmental safety, and the availability of abundant local resources, although limitations remain in terms of residual activity and consistency of effectiveness. Thus, botanical insecticides have the potential to be developed as an important component of environmentally friendly and sustainable Integrated Pest Management (IPM) strategies to protect stored commodities from losses caused by storage pests.

Abstract

Fruit flies (Bactrocera spp.) are among the most serious pests in citrus production due to their high infestation potential and detrimental effects on fruit quality. This study examined fruit fly abundance based on sex and citrus tree clones and evaluated the impact of trap placement position on fruit fly populations in Sleman Regency, Indonesia. The experiment was conducted in August 2025 at Pusat Inovasi Agroteknologi, Universitas Gadjah Mada, employing a Completely Randomized Block Design with four trap placement treatments: medium inside, high inside, medium outside, and high outside. Medium and high trap heights were set at 1 m and 2 m above ground level, respectively, with traps positioned either inside or outside the tree canopy. Observations were performed at two-day intervals over 15 observation periods on three citrus species: Siamese orange (Citrus nobilis Lour.), kaffir lime (Citrus hystrix), and grapefruit (Citrus maxima (Burm.) Merr.). The results showed that fruit fly abundance was consistently higher in traps installed outside the tree canopy than in those placed inside across all citrus species and observation periods. No significant differences were detected between medium and high trap heights within the same placement location. Female fruit flies exhibited greater population variability than males, indicating higher sensitivity to environmental factors. Furthermore, correlation analysis revealed strong positive relationships among citrus clones, suggesting similar levels of susceptibility to fruit fly infestation. In conclusion, the findings highlight that trap placement location plays a more decisive role than trap height in influencing fruit fly abundance on citrus trees.

Abstract

The problem faced when using plant-based pesticides is that they are impractical, because plant-based pesticides must be made every time they are applied, so it takes more time. So far, vegetable herbicides have been made 1-3 days before application. It is not yet known exactly how long the shelf life of botanical herbicides is to suppress weeds. One of the vegetable herbicides that can be used is made from reed roots which can release allelopathic compounds. The ingredients found in the rhizomes of reeds (Imperata cylindrica) are known to contain allelopathic compounds in the form of saponins, tannins, arundoin, phenol, isoarborinol, cylindrin, simiarenol, campestrol, stigmasterol, β sitisterol, scopoletin, phydroxybenzalaldehyde, catechol, chlorogenic acid, oxalic acid, d-malic acid, citric acid, potassium, large amounts of calcium and 5-hydroxytryptamine. The aim of this research was to determine the effectiveness of the shelf life of the botanical herbicide Alang-alang roots on the growth of the weed A. conyzides. The design used in this research was a Completely Randomized Design (CRD) with 6 treatments and 4 replications and observations were carried out for 30 days. Making a botanical herbicide in the form of alang-alang root solution. The dose used is 150 ml. Data on the phytotoxicity of plant-based herbicides of Alang-alang roots were analyzed using analysis of variance with the F test and BNT further test at 5% level. The results of this study indicate that the shelf life of botanical herbicides affects the phytotoxicity of the weed A. conyzoides. All long storage treatments were considered to have an effective effect in suppressing bandotan weed (Ageratum conyzoides).

Abstract

Chili is an important horticultural crop that is cultivated in large quantities every day. However, production is often disrupted by diseases, one of which is anthracnose caused by the fungus Colletotrichum spp. Environmentally friendly control can be done with natural ingredients such as babadotan extract which contains antifungal compounds such as steroids, terpenoids, phenols, saponins, fatty acids and alkaloids. This research aims to test the ability of babadotan (Ageratum conyzoides L.) leaf extract to suppress the growth of Colletotrichum spp. in vitro. The research took place at the Phytopathology Laboratory, Faculty of Agriculture, Lambung Mangkurat University from October 2023 to May 2024. The method used RAL with 5 treatments and 4 replications. The results showed that BCE treatment (9% babadotan leaf extract) had the lowest growth inhibition at 40.02%, while BCB (3%) 34.94%, BCC (5%) 22.39%, and BCD (7%) 8.52%.
