Red rice is starting to be widely cultivated because of its health benefits, but its cultivation often experiences problems, one of which is fusarium wilt disease. The aim of this research is to determine the effect of PGPR (Plant Growth Promoting Rhizobacteria), Trichoderma sp. and Bokashi Kiambang on the incidence of fusarium wilt disease in red rice. Method using completely randomized design. The research was conducted in the wetlands of Cempaka sub-district, Banjarbaru. This observation was carried out four times, namely before treatment, ten days after the first treatment and every 10 days. The results of observations of the incidence of fusarium wilt disease were yellowish green leaves appeared, quickly dried and the plants died. The results of disease incidence in the PGPR application treatment, Trichoderma sp and bokashi kiambang had no effect. PGPR, Trichoderma sp and bokashi kiambang had no effect because the rice plants entered the generative phase. Use of a combination of PGPR, Trichoderma sp. and bokashi kiambang can increase the number of grains/panicles in 60 days of treatment. 70 days and 80 days was 223.00 grains/panicle, while in the control it was only 147.00 grains/panicle. The results of using a combination of PGPR, Trichoderma sp. and bokashi kiambang can increase the weight of 100 grains weighing 2.18 g compared to the control of only 1.15 g.

Chili is a commodity that experiences price fluctuations due to high demand. In 2021, cayenne pepper production in Indonesia will decrease by 8.09% compared to 2020. Anthracnose disease, caused by the fungus Colletotrichum sp., can reduce productivity by 5-30%, even causing crop failure. Biological control using Streptomyces sp. and plant-based pesticides such as betel leaves and kelakai leaves are environmentally friendly alternatives. This study evaluated the effectiveness of this combination against anthracnose in hiyung chilies. The results of the study showed that the application of the bacteria Streptomyches sp., the vegetable pesticide Kelakai Leaf, the vegetable pesticide Betel Leaf and their combination were able to reduce the incidence of anthracnose disease with disease incidence ranging from 15.05% -21.33% compared to controls whose disease incidence was 33.24%. The results of the analysis of the effectiveness of disease control showed that there were 4 treatments that were quite effective, Betel 54.72%, Streptomyces sp. 46.48%, combination of Betel and Streptomyces sp. 43.65%, and a combination of kelakai and Streptomyces sp 40.94%. The observation results also showed that the Betel biopesticide treatment was the best treatment in producing the highest crop of 30.56 cm and increasing the wet weight with a yield of 83.38 g, followed by the Kelakai treatment which also produced the highest yield of 82.03 g. Apart from that, all the treatments given were able to accelerate the flowering age of chilies by 56.08-57.52 days compared to the control of 58.28 days.

In recent years, the rubber industry in Indonesia has experienced problems because rubber plants have been attacked by leaf fall disease which can reduce latex production by up to 50% and even cause them to wilt and die. In 2021, leaf fall disease began to be detected attacking rubber plantations in South Kalimantan, but it has not been reported on rubber plantations in Barito Kuala. This research aims to determine the distribution of rubber leaf fall disease on rubber plants in Barito Kuala Regency. The method used is a survey method, sampling was carried out using stratified purposive random sampling and creating a questionnaire as supporting data. The survey was conducted in Barito Kuala Regency in four selected rubber growing center sub-districts, namely Wanaraya, Barambai, Marabahan and Anjir Pasar sub-districts, three villages were selected in each sub-district. Each village was sampled diagonally with 25 trees at each sample point so that there were 125 trees per village with a total sample area of 12 villages. So in four sub-districts there were 1,500 trees observed. The parameters observed were the incidence and severity of rubber leaf fall disease. The severity of rubber leaf fall disease in Barito Kuala Regency is quite severe with an average of 65%. The level of severity in each location varies, starting from 48% in Gandaria Village, Anjir Pasar District, to 82% in Kolam Kiri Dalam Village, Barambai District. In Barambai District the average disease severity level is 70%, in Wanaraya District it is also almost the same, namely 71%. In Marabahan District it is lower, namely 66%. The lowest sub-district is Anjir Pasar Sub-district which only has 52%.

Sigatoka of banana caused by Mycospherella sp. is an important disease, since it causes yield losses. Resistant variety is considered a promising approach for sigatoka disease management. This study was aimed to evaluate the resistance of local banana cultivars from South Kalimantan against sigatoka disease. The fungus was isolated from leaves of Kapas cultivar showing severe symptoms of sigatoka disease, onto potato dextrose agar medium. The isolate was then confirmed as Mycosphaerella sp. following Koch’s postulate. Level of resistance is determined based on symptoms development. Resistance of local banana cultivars can be differentiated into susceptible (‘Awak’, ‘Jaranang’, ‘Kapas’, ‘Mas’, and ‘Paikat’), medium resistant (‘Ambon’, ‘Kepok’, ‘Mas Bantan’, ‘Mauli’, and ‘Talas’), and resistant (‘Tarati’). In general, the symptom was visible 2 to 8 days after inoculation. The longer incubation period the more resistant response of banana varieties. Incubation period was negatively correlated to the disease intensity, but it is not correlated with stomatal density.

Large chilies are a type of vegetable that is widely used in Indonesia due to the large demand for chili consumption by the public. However, there is also a decrease in production yields due to attacks by plant pests (OPT) in the form of diseases such as fusarium wilt caused by the fungus Fusarium sp. One safe and environmentally friendly alternative control that can be given to plants is Trichoderma sp. because the content of trichoderma is considered capable of having a positive impact on plants. This study aims to determine the isolates of Trichoderma sp. Different types are used, which isolate is more effective and is able to suppress fusarium wilt in large chili plants. The research method was a completely randomized design with one factor consisting of 5 treatments with 4 replications, a total of 20 experimental units. The research was carried out at the Phytopathology Laboratory, Department of Plant Pests and Diseases, Faculty of Agriculture, ULM and the Experimental Garden, Faculty of Agriculture, ULM. The result of this research is the application of Trichoderma sp. gives results that have a real effect on plant height and are able to reduce the percentage of cases of fusarium wilt disease in chili plants. The best treatment is for Trichoderma sp. isolate from Isolate from Hiyung Village, Tapin with the lowest percentage of disease incidence of 25% and stimulated plant height growth with a height of 28.09 cm.

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.
