The role of salicylic acid on host-pathogen interactions of sweet potato scab disease (E. batatas) was done by measuring (1) the level of resistance of sweet potato cultivars to scab disease, (2) salicylic acid content in sweet potato leaves before inoculation, 3 days, 6 days, and 9 days after inoculation, and (3) effect of salicylic acid to the germination of E. batatas conidia. The result showed that there were different responses of sweet potato cultivars to pathogens infection. Inoculation with E. batatas isolate from Wonosobo (WO2) showed resistant reaction on Muaratakus, moderate resistant on Cangkuang, moderate susceptible on Malothok, and susceptible on Mlg 12549. Resistant cultivar (Muaratakus) has higher salicylic acid content than moderate resistant (Cangkuang), moderate susceptible (Malothok), and susceptible cultivar (Mlg 12549). Salicylic acid inhibited germination of E. batatas conidia.

The Wilt in tomato plants is caused by Fusarium oxysporum sp. Lycopersici. Fusarium oxysporum is soil borne which causes considerable losses. FMA as a biological agent provides an alternative opportunity to control root diseases such as fusarium. The purpose of this study was to study the treatment of FMA inoculation which is appropriate while controlling the damage of tomato plants caused by fusarium. The research design used was the experimental method in Completely Randomized Design. The results showed that the treatment of mycorrhizae inoculated one week before planting and continued with fusarium inoculation at the time of planting showed good results in inducing the resistance of tomato plants to fusarium disease. This is evidenced by root colonization in tomato plants by 53% and the average intensity of attacks by 3.14%. The mycorrhizal treatment inoculated one week before planting and followed by fusarium inoculation at planting also showed good results in increasing the growth of tomato plants compared to other treatments applied by mycorrhiza.

Common corn rust disease caused by the fungus Puccinia sorghi, causes small spots on the upper and lower surfaces of the leaves which then spread to the entire leaf surface, causing a decrease in photosynthetic yield. Losses due to this disease are 45-60%. This study aims to explore the resistance of corn varieties to rust disease. This research was arranged in a descriptive research design using 240 plants of corn. The maize varieties tested were Pertiwi 3, Betrass, Bissi 2, Bissi 18, Bima, and Prafi Merah varieties. The results showed that the intensity of disease increased continuously every week from the first appearance of 5 WAP to 11 WAP. At 11 WAP the severity of the disease was 76% Pertiwi 3, Betrass 91%, Bissi 2 82%, Bissi 18 89%, Bima 80% and Prafi Merah 92% so that all test varieties were classified as susceptible varieties. The susceptibility was triggered by the test variety's gene system which was not sufficient to inhibit the rate of development of pathogens with high virulence. In addition, weather factors with rainfall ranging between 73and 90%, adequate optimal temperatures ranging between 25.7oC and 28.8oC and heavy rains that occur continuously for 24-26 days strongly support production and sporadic distribution in the crop resulting in an increase in severity disease.

Ransiki area is the capital of South Manokwari regency which has tourism potential with its exotic natural beauty so that it is visited by many tourists. In addition, the area has a lot of endemic plant diversity that has the potential to produce secondary metabolic compounds, one of which is black fruit trees (pohon buah hitam). The leaves of the black fruit tree contain secondary metabolic compounds of tannins (8.34-37.26%), more than flavonoids and alkaloids. For the development of environmentally friendly technological innovations, the Faculty of Agriculture UNIPA continues to develop black fruit tree leaves as liquid and powder botanical pesticides, as well as the biological pesticide from Trichoderma sp with inoculum sources obtained around the cocoa plantation in the Ransiki area. Cocoa plants are managed by indigenous people, immigrants and companies/cooperatives, have produced food products in the form of chocolate bars and cocoa powder, have potential for regional income and sales have reached overseas. Community service activities carried out from October to December 2021, use counseling methods, technical guidance/training, dissemination, and demonstration plot, mentoring. This activity is in line with the increasing promotion of tourist attractions in the Ransiki area, aiming to introduce and utilize regional superior agricultural products that can be applied to cocoa plants. Furthermore, it is expected to provide an increase in regional income, welfare of farmers and companies/cooperatives, and improve the quality of cocoa products from organic farming towards sustainable agricultural development. The application of botanical pesticides in cocoa plantations has proven to be able to control cocoa pod sucking ladybugs (Helopelthis spp), stem borers (Zeuzera coffea), and the dissemination of pesticide products are used as guidelines for preparing work plans for the Department of Agriculture, Cooperatives, Industry and Trade, South Manokwari Regency

Salah satu daerah yang membudidayakan jagung secara terus menerus setiap musim di Manokwari adalah Kampung Copti Prafi. Kondisi ini menyebabkan mudahnya berkembang penyakit karat daun. Oleh karena itu, tujuan penelitian ini adalah mengevaluasi intensitas serangan penyakit, laju perkembangan penyakit, sifat ketahanan jagung dan pengaruh faktor-faktor iklim terhadap intensitas dan laju perkembangan penyakitnya terhadap penyakit karat daun jagung tersebut. Analisa data dilakukan secara tabulasi dan menggunakan gambar yang dihasilkan dari microsoft excel 2016 untuk membandingkan variabel-variabel pengamatan. Hasil penelitian yang diperoleh menunjukkan bahwa patogen penyebab penyakit karat di Kampung Copti adalah Puccinia polysora. Intensitas serangan dimulai pada 5 minggu setelah tanam, kemudian terus-menerus mengalami peningkatan hingga minggu ke 11 dimana semua varietas yang diuji menunjukkan respons peka. Laju perkembangan penyakit juga mengalami peningkatan seiring dengan meningkatnya intensitas serangan dan dikategorikan berat. Curah hujan sangat menunjang perkembangan penyakit. Peningkatan jumlah curah hujan dapat menyebabkan peningkatan perkembangan penyakit karat. Curah hujan menyebabkan lahan pertanaman menjadi basah dan menimbulkan evapotranspirasi yang menyebabkan kebun menjadi lembab dan memudahkan distribusi penyakit dari satu tanaman jagung ke tanaman jagung yang lainnya pada kebun yang sama atau antar kebun. Kondisi perkembangan penyakit yang meningkat juga disebabkan oleh kepekaan tanaman terhadap ras patogen yang sangat virulen terhadap tanaman jagung.
