Abstract

Penyakit keriting kuning cabai yang disebabkan oleh Begomovirus merupakan salah satu kendala produksi cabai di Indonesia. Salah satu alternatif pengendalian penyakit ini menggunakan Plant Growth Promoting Rhizobacter (PGPR) yang diharapkan  dapat mengurangi penggunaan pestisida  yang berdampak buruk bagi lingkungan dan kesehatan. Penelitian ini bertujuan untuk mengetahui efektifitas Streptomyces spp. dalam menekan penyakit keriting kuning, pertumbuhan tanaman dan hasil panen cabai besar. Penelitian dilakukan di lahan petani di Desa Harjobinangun, daerah Pakem, Kabupaten Sleman, Yogyakarta. Menggunakan varietas cabai Twist dan  Isolat Streptomyces spp. koleksi Laboratorium Bakteriologi Tumbuhan dengan konsentrasi 108 CFU/ml. Hasil penelitian menunjukkan bahwa Streptomyces spp. mampu menurunkan  insidensi dan intensitas penyakit pada fase vegetatif 54,17% dan 59,06%. Sedangkan pada fase generatif 50% dan 65,92%. Streptomyces spp. dapat meningkatkan tinggi dan diameter tanaman  pada fase vegetatif 4,61% dan 6,05%. dan pada fase generatif 27,28% dan 1,11%. Streptomyces spp. dapat meningkatkan panjang akar, volume akar dan jumlah cabang produktif 4,40%, 20,70%, dan 24,81%. Streptomyces spp. dapat meningkatkan jumlah dan bobot total panen 15,5% dan 16,72%.  Streptomyces spp. dapat meningkatkan kualitas buah ditunjukan dengan peningkatan panjang, diameter, dan bobot buah  layak jual  6.26%, 12,80%, dan 11,39%.

Abstract

Morphology characters and mating types distribution of Phytophthora capsici from black pepper in Java IslandPepper (Piper nigrum) is one of the most important spice crops in Indonesia.  Recently its production declining due to infection of foot rot disease caused by Phytophthora capsici. This pathogen has two different mating types, namely A1 and A2, in which the presence of opposite two mating types is important for sexual reproduction and formation of oospores. The movement of pepper seedling from one area to another is highly facilitated alteration of  mating type distribution map of P. capsici. The objectives of this research were to determine the morphological characteristics and the spread of mating types of P. capsici in Java. Morphology characters of P. capsici isolates were indicated by variation in sporangial size and shape, as well as types of colony appearance. The length (l) and width (w) of sporangium were in the range of 15.1–76.2 µm and 9.8–44.8 µm, respectively; while the l/w ratio was 1.12–2.27. Mating type assay showed that A2 type was more dominantly found than A1 type. This study found two different mating types present in the same area, i.e. Regency of Pacitan (East Java) and Regency of Sleman (Special Region of Yogyakarta). The findings of this research suggested that it is required more strict control strategy on the mobilization of black pepper seedling particularly in the area where the certain mating type is not found yet so that the emergence of new more virulent genotype of pathogen can be prevented.

Abstract

Effect of Various Yeasts Antagonists on Anthracnose Disease and the Shelf Life of MangoPostharvest decay on mango may occur due to physiological damage and/or postharvest disease especially anthracnose. This postharvest decay may decrease the quality of mango fruit. The use of antagonists yeast as biocontrol agent is an alternative control measure for postharvest diseases of fruits. This study aimed to screen yeast species as biological control agents and in the same time delaying the maturity of fruits to extend its shelf life.  Six isolates of yeasts were evaluated, namely Cryptococcus albidus, Cryptococcus terreus, Aureobasidium pullulans, Rhodotorula minuta, Candida tropicalis, Pseoudozyma hubeiensis); fungicides treatment using azoksistrobin was applied for comparative treatment. The study was conducted at two temperature conditions, namely room temperature and 15 ° C. It was evidenced that C. albidus, A. pullulans, and C. tropicalis were effective to control anthracnose disease on mango under both temperatures.  Furthermore, C. tropicalis and A. pullulans were able to extend manggo shelf life for 21 days at room temperature and for 54 days at 15 °C, respectively.

Abstract

Growth and Development of Inoculated in Northern Black Wattle Seedling with Seed Borne Bacterial PathogensNorthern black wattle (Acacia auriculiformis) is a fast growing species that has multipurpose benefits such as pulpwood, solid wood, firewood, charcoal and pellet. Seed-borne bacterial pathogens were reported to reduce seed germination and seedling growth. The objective of this study was to evaluate effect of seed borne bacterial pathogen of A. auriculiformis on seed germination and 12 weeks-old seedling growth. Bacterial seed inoculation was performed by soaking the seed into respective bacterial suspension for 2 hours. The tested bacteria were Acinetobacter sp., Alcaligenes faecalis, Burkholderia cepacia complex, Escherichia hermannii, Paenochrobactrum sp., Pseudomonas stutzeri, Ralstonia sp., and Salmonella bongori. The results showed that all tested bacteria could reduce seed germination, but those does not affect seedling growth significantly. All tested bacteria excluding Acinetobacter sp. could inhibit seedling growth and development.

Abstract

Diversity of Postharvest Fungi on Shallot Bulbs Variety Bima BrebesIn Indonesia, shallot (Allium ascalonicum) is horticultural main commodity after hot pepper. Significant yield losses can be caused by postharvest fungi infection. Research on the diversity of postharvest fungi on shallot bulbs has been conducted in some countries, unfortunately little is done in Indonesia. The study was aimed to obtain information on the diversity of postharvest fungi infecting shallot bulbs variety Bima Brebes from several traditional markets in Bogor City. Shallot bulbs were collected in January and February 2016. The study consisted of fungal isolation from shallot bulbs, fungal pathogenicity test, and identification of pathogenic fungi based on morphological and molecular characteristics. Morphology identification was based on the color of fungal colony, growth pattern, as well as somatic and reproduction structures. Several species of pathogenic fungi were successfully identified from shallot bulbs i.e. Alternaria alternata, Aspergillus niger, Colletotrichum gloeosporioides species complex, Fusarium fujikuroi species complex, F. oxysporum, F. solani, Penicillium citrinum and P. pinophilum.  Among these fungi, the highest pathogenicity was shown by C.  gloeosporioides species complex.
