One of strategic fruit commodities was avocado that had high economic value. Pest and diseases were main problems faced by farmers. This study identified diseases and pest associated with avocado plantation intercropping with mango and durian in Watulembu district, Wonogiri Regency through symptoms and its controls. The observation was done to the abnormalities avocado plants and the field condition surrounding the planting area. It was conducted by visual observation, recorded using a digital camera, and then described and identified based on their symptoms and a literature review. The results of our observation were Algal leaf spot, Anthracnose, Sooty mold, and Planococcus citri. Pest and plant disease could be controlled by cultural technique, avoid plant stress, and also using chemical pesticide.

Post-harvest products are perishable and vulnerable to diseases that lead to quality deterioration and yield loss. One of the primary diseases found in most post-harvest products is caused by fungal pathogens. This study identified fungal pathogens associated with post-harvest products through morphological characterization. Fruit and vegetable samples were collected from traditional markets and fruit stores in Central Java. The results of fungal pathogens identification causing disease on post-harvest products showed that Pestalotiopsis sp and Neopestalotiopsis sp. were found on guava with white blackish mycelium, present concentric ring and blackspot, Aspergillus sp. on tomato with yellow-greenish mycelium, present concentric ring only, Botrytis sp. with grey mycelium and Rhizoctonia solani with white greyish mycelium and present of a concentric ring on apple, Rhizoctonia solani with greyish black and present of blackspot on mango, and Colletotrichum sp. with white greyish mycelium and present of a concentric ring, conidiomata and blackspot on citrus. This study concluded that the most fungal pathogens on post-harvest that we found were Pestaloptia sp., Rhizoctonia solani, Aspergillus sp., Botrytis sp., and Colletotrichum sp.

Red chili is cultivated practically everywhere and plays a crucial role in Indonesian culture, economy, and cuisine. Plant diseases have been the main factor driving the country’s yield reduction of red chili. This research was conducted to observe chili plant diseases in Hargobinangun Subdistrict, Pakem District, Sleman, Yogyakarta. Chili variety Twist-42 was planted in the area. The Twist-42 variety is a local variety that is well adapted in the middle plains between 450 – 650 masl (meters above sea level) and is a good variety in both the dry and rainy seasons. There were 360 red chili plants as samples. The diseases found are Yellow leaf curl disease, Anthracnose, Ralstonia wilt, and Root knot nematode (Meloidogyne spp.).

Citrus Vein Phloem Degeneration (CVPD) is transmitted by the insect vector Diaphorina citri is still a major obstacle to world citrus production. Vector handling still relies on chemical insecticides which are not environmentally friendly and less effective. This study was conducted to identify the ability of dried guava leaf extract in reducing the olfactory response of D. citri. Y-tube olfactory test was conducted to identify the repellency effect of a mixture of citrus leaf extract and guava (Psidium guajava) leaf extract at various leaf ages and in various proportions to vector and its predator (Menochilus sexmaculatus). The results showed that guava leaves had a repellent effect on D. citri, but not on M. sexmaculatus. The repellant effect was higher on young guava leaves than on medium and old ones. Red guava leaves have a highest repellant effect than white guava and non-seed guava leaves. Guava leaf extract is an alternative means to control D. citri. However, the types of compounds that function as repellants need to be studied further.

Black pepper (Piper nigrum L.) is a high-value spice crop whose productivity is strongly influenced by plant health and the microbial conditions in the rhizosphere. This study aimed to characterize the fungal communities in the rhizosphere of healthy black pepper plants grown in fields with a history of pest and disease outbreaks, using a metagenomic approach based on ITS1 sequencing via the Illumina platform. Rhizosphere soil samples were collected from healthy black pepper plants in a plantation located in Tribuana Village, Banjarnegara, Central Java, which had experienced pest and disease incidences in the previous growing season. Taxonomic composition, relative abundance, and diversity indices (Shannon, Simpson, and Richness) were analyzed. The results revealed that the fungal community was dominated by organic matter- decomposing fungi (57.29%), followed by plant growth- promoting fungi (PGPF) at 19.82%. These two groups not only exhibited quantitative dominance but also showed high diversity and evenness values, indicating ecological stability within the root system of healthy pepper plants. These findings highlight the importance of cultivation practices that support the persistence of functional microbial communities, such as organic matter amendments and the application of biofertilizers. In conclusion, the high dominance and diversity of decomposer fungi and PGPF in the rhizosphere of healthy black pepper plants underscore their critical role in maintaining plant health and provide a scientific basis for sustainable soil management strategies. Pathogenic fungal communities accounted for 12.76% of the total abundance, exhibiting moderate diversity and relatively high evenness.

Repellency is one of strategies to reduce Diaphorina citri attack. Guava leaf extract (GLE) and horticultural mineral oil (HMO) are well-known as repellents against D. citri but have short persistence. This research was conducted to increase the persistence of GLE and HMO extracts by using simultaneous co-delivery as part of environmentally friendly control of D. citri. The treatments used were 5% GLE, 5% HMO, 5% GLE + 5% HMO, 5% encapsulated GLE, 5% encapsulated HMO, 5% encapsulated GLE + 5% encapsulated HMO, and aquadest as control. The result shows that 5% HMO, 5% GLE + 5% HMO, and 5% encapsulated GLE have a repellency effect on D. citri. In the non-encapsulated treatments, the percentage of D. citri stayed at treated citrus leaves increased significantly at 9 and 12 hours after application except 5% GLE + 5% HMO. Exposure to 5% GLE, 5% HMO, and 5% encapsulated GLE. The most dominant of GLE compounds was lactose and d-Glycero-l-gluco-heptose. The most dominant of HMO compounds were 17-Pentatriacontene, Tetrapentacontane 1,54-dibromo- and tert-Hexadecanethiol. Encapsulation of 5% GLE can increase the persistence of GLE as a repellent compound for D. citri, but this effect does not occur in HMOs.
