Abstract

The sago plant is a staple food for the people of Maluku and Papua and has many benefits and advantages to continue to be developed. A group of phylloplane microbes grow and spread on the surface of the leaves. The objective study is to find isolates of phylloplane bacteria from sago accession Makanaru and determine the inhibition of these bacteria against the growth of Rhizoctonia solani Kuhn. Sampling of sago plants (upper, middle, and lower leaves) was conducted in Negeri Seith, Leihitu District, Central Maluku Regency. Based on the isolation results, 21 isolates of phylloplanes bacteria were obtained and ready for further testing. From the results of hypersensitive test selection, 14 non-pathogenic isolates of phylloplane bacteria were obtained. Furthermore, tested the inhibitory power of phylloplane bacteria in suppressing the growth of the fungus, 3 phylloplane bacteria isolates were obtained with strong inhibitory, namely DA3.3, DT3.2, DT3.1 followed by 3 isolates DB4, DB4.2, and DB4.4 (medium inhibitory) which have the potential to be developed as biological agents.

Abstract

The study aims to determine the level of damage to potato tubers due to post-harvest pathogenic fungi attacks in several traditional markets in Ambon City. This study is a survey study at the Mardika, Passo, and Rumahtiga markets. The results of the study found one type of post-harvest pathogenic fungus that attacks potato tubers in traditional markets in Ambon City, namely Fusarium spp. which is the cause of dry rot disease in potato tubers. The level of damage to potato tubers due to Fusarium spp. attacks is classified as severe, found in the Mardika market at 70.81% and the Transit Passo market at 60.91%. While in the Rumahtiga market only 31.62% are classified as moderate damage.

Abstract

Maize (Zea mays) plays an important role in the diet of the community after rice and has the potential to be a substitute for rice. One of the causes of the decline in corn productivity is the presence of plant-disrupting organisms, namely corn stalk borer (Ostrinia furnacalis) and corn cob borer (Helicoverpa armigera). Waimital Village, Kairatu Subdistrict, West Seram Regency is one of the corn center villages where farmers rely on synthetic insecticides in pest control without knowing the intensity of the damage caused. This study aims to determine the number of populations and the intensity of damage caused by Ostrinia furnacalis and Helicoverpa armigera pests that attack corn plants, as well as the relationship between the number of populations and the intensity of damage to each pest. The method used was the survey method in the corn planting area of Waimital village, then 5 farmers were taken with the determination of plants divided into 4 plots with details of each plot of 10 plants. The results of this study showed that the average population of Ostrinia furnacalis was 4.37 heads, the average population of Helicoverpa armigera was 1 head, the average damage intensity of Ostrinia furnacalis was 42.71% (medium criteria), the average damage intensity of Helicoverpa armigera was 11.83% (light criteria) and the relationship between Ostrinia furnacalis and Helicoverpa armigera pest populations and damage intensity showed that the larger the pest population, the higher the damage intensity.
