Abstract

Color traps are one way to control insects around plants. This research aims to determine the type of color and height of the trap on insect attraction to chili plants in 2 generative phases and vegetative phase. This research took place in Bentok Darat Village, Bati-Bati District, Tanah Laut Regency, South Kalimantan Province. The method used was (RAL) with 2 factors and 3 repetitions. The first color factor is W1: Yellow, W2: Green, W3: Red and the second factor is the height of T1: 30 cm, T2: 60 cm and T3: 90 cm. The results of this research were that yellow traps had the highest number of insect catches, namely 1,634 and at a height of 30 cm, yellow traps had the highest number of catches, 362. From this research, the total number of insect catches obtained was 3,676 individuals. In the vegetative phase there were 1,629 insects and in the generative phase there were 2,047 insects.

Abstract

Postharvest plant pest organisms include bacteria. This research aims to determine the colony morphology characteristics and physiology of post-harvest pathogenic bacteria of feed corn (Zea mays L.), and to determine its genus. The method used was purposive sampling and samples were taken from the PT. Arutmin Indonesia Site Satui storage warehouse in Satui District, Tanah Bumbu Regency. Bacteria isolated from samples and positive for being pathogenic on corn seeds were identified by observing the colony's morphological characteristics and physiology. The results showed that the pathogenic bacteria identified were bacteria from the genus Dickeya and there were still bacteria of unknown genus, and no bacteria from the genus Pantoea were found. The first bacteria of the Dickeya genus are white with a grayish circular pattern in the middle, round to irregular shape, uneven edges, flat surface, and not shiny. These characteristics are the same as those of the Dickeya zeae bacteria. The second Dickeya genus of bacteria looks grayish white in the middle and bright white at the edges, round to irregular in shape, the edges look slightly blurry and slightly stringy, the surface is convex to flat, and shiny. These characteristics are the same as those of the Dickeya chrysanthemi bacteria. Based on their physiological characteristics, the bacteria obtained have similarities with the bacteria of the genus Dickeya, namely they are gram negative, can grow in aerobic and anaerobic conditions, can produce the catalase enzyme, are not yellow if grown on YDC media, can cause soft rot, and can produce the enzyme lecithinase.

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

Fungal contamination in stored corn grain not only reduces grain quality but alsoposes risks to animal and human health due to mycotoxin production. This study highlights the importance of early detection and identification of fungal pathogens in corn as a key aspect of plant protection and postharvest management, as well as the need to determine the types and concentrations of toxins produced. Corn samples were collected from a storage warehouse in Satui Village, Kota Baru Regency, South Kalimantan. Fungal isolation was conducted at the Phytopathology Laboratory, Department of Plant Pests and Diseases, Faculty of Agriculture, Universitas Lambung Mangkurat. PCR analysis and gene sequencing were performed at the Genetics Sciences Laboratory, Jakarta, while toxin type and content analyses were carried out at the Animal Husbandry Laboratory, Universitas Gadjah Mada, Yogyakarta. From 11 microbial isolates obtained from corn grain, only one fungal species was identified, namely Aspergillus flavus. This species was found to produce 8.00 ppb of aflatoxin, which remains below the established safety thresholds of 15 ppb for B1 and 20 ppb for total aflatoxins.

Abstract

Red rice (Oryza nivara L.) is a type of rice whose consumption level is increasing every year. However, obstacles in cultivating red rice often occur due to disease attacks, one of which is fusarium wilt. The aim of this research was to determine the effectiveness of varying the application time of trichocompost combined with betel leaf solution in suppressing the incidence of fusarium wilt disease in red rice plants. The research method used a Completely Randomized Design (CRD) which was carried out in the Phytopathology laboratory and greenhouse of the Department of Plant Pests and Diseases, Faculty of Agriculture, Lambung Mangkurat University, Banjarbaru. The results of the study showed that the treatment given trichocompost and betel leaf solution with application times a week before planting, during planting, and a week after planting was able to reduce the incidence of disease by up to 35.00% with a control effectiveness percentage of 62.16% compared to the control treatment which had the incidence disease amounted to 92.50%. Application of trichocompost and betel leaf solution with varying times on red rice was able to extend the incubation period of the pathogen up to 20.25 days compared to the control, namely 12.53 days. Plants that were given the application of trichocompost and betel leaf solution were also able to increase plant height by up to 102.83 cm with a total of 8.78 tillers compared to the control without treatment which had a plant height of 76.30 cm with a total of 4.30 tillers.
