Abstract

Using biological agents to control fusarium wilt is still not maximal result, based on that need to search a potensial indigeneous biological agents specific location. The experiment conducted to study the role biological agents of arbuscular mychorrhizal fungi indigenous to control fusarium wilt diseases. Twenty four isolates were evaluated for the potensials to reduced fusarium wilt incidence. This research was arranged by Randomized Block Design (RBD) on green house experiment. The aim of this research is to investigate the ability of arbuscular mychorrhizal fungi isolates to reduce fusarium wilt on banana seedling. The results showed that all arbuscular mychorrhizal fungi isolates indigenous from healthy banana rhizosphere reduced fusarium wilt development and increase banana growth.Three isolates (Gl1KeP4, Gl1BuA4, Gl2BuA 6) could control Fusarium wilt until 100% with longer incubation periode and lower disease of banana seedlings as Plant Growth Promoting Fungi. Key words: Arbuscular Mychorrhizal Fungi Indigenous, Fusarium Wilt, Musa sp

Abstract

Blood diseases caused by Ralstonia solancearum Phylotype IV is a major cause of production loss of banana in Indonesia, particularly for areas in West Sumatera. Currently there is a lack of information on blood diseases. The objective of this study was to obtain data of insect diversity and its potential as a dissemination agent of R. solanacearum Phylotype IV in West Sumatera. This research was conducted with a purposive sampling method in the Tabek Panjang highlands, District of Baso, Agam Regency and Pasar Usang lowland, district of Batang Anai, Pariaman Regency, West Sumatera. The results showed that banana plants infected by R. solanacearum Phylotype IV have a high diversity of flower-visiting insects. The diversity of insects in the lowlands is higher than that in highland and mainly are dominated by Trigona spp. (Hymenoptera: Apidae), Drosophila sp. (Diptera: Drosophilidae). To test the potential of both insect as vector of the blood diseases, isolated and identification of the bacteria using triphenyl tetrazolium medium chlorid (TTC) was used. Result showed that bacteria isolated from both insect are R. solanacearum hence providing evidence of the insect as vector of the blood diseases. Both insects have the potential to be vector of R. solanacearum Phylotype IV in West Sumatera. The identification of the bacteria that causes the disease. The identification of bacteria that is spread by flower visitors insects are R.solanacearum Phylotipe IV.

Abstract

During the last three years, several snails as pests that attacked vegetables, especially cabbages (Brassicaceae) in the highland vegetable crop center of Mount Marapi, were found to cause damage. This study aimed to obtain the species, population, and attack rate of snails pests on the cabbage plants. The study was conducted using a survey method with purposive sampling conducted from July to September 2019 with the criteria of observing plants two weeks after planting and determining the sample diagonally. The results showed that cabbage plants in Mount Marapi, Agam Regency, were attacked by two snails, namely Bradybaena similaris and Parmarion sp. The population of B. similaris was higher than that of Parmarion sp. Mustard plants are most at risk of being attacked by snails, with the highest percentage and intensity of attack even though the damage category is classified as moderate. Mustard plants are also among the first time to be attacked by snails. Cultivation techniques affect the density and attack rate of pest snails at the research site. Key words: Slug attack level, species and population density, Bradybaena similaris, Parmarion sp.

Abstract

In modern cultivation processes indiscriminate use of pesticides and fertilizers, has led to substantialpollution of soil, air and water. So, there is an urgent need to solve the problem. Rhizobacteria are bacteria thatcolonize plant roots, and these bacteria are known to stimulate growth and thereby reduce incidence of plantdisease by direct and indirect mechanisms. A total of 136 rhizobacteria isolates were isolated from differentrhizosphere soils in central areas of production of onions in Indonesia. These isolates were screened for theircapability to enhance growth and protect onions against bacterial leaf blight disease-caused by Xanthomonasaxonopodis pv.allii. The results showed that ten isolates can enhance growth and protect onions against bacterialleaf blight diseases. Five isolates were isolated from West Sumatra, four isolates from Java and one isolated from North Sumatra. All isolates produced indol-3-acetic acid with different concentrations. Molecular identification of ten isolates belong to Bacillus sp, Pseudomonas sp, Stenotrophomonas sp and Serratia sp.

Abstract

Penyakit layu Stewart merupakan penyakit penting pada tanaman jagung. Di Indonesia penyakit ini baru dilaporkan pada tahun 2008 dan pada tahun 2015 dinyatakan sebagai organisme pengganggu tumbuhan karantina (OPTK) kategori A2. Informasi tentang perkembangan dan penyebaran penyakit ini masih terbatas. Tujuan penelitian adalah: Mendapatkan model kurva perkembangan (temporal) dan pola penyebaran (spatial) penyakit layu Stewart pada tanaman jagung pada dua periode tanam. Percobaan lapangan dilaksanakan selama dua musim tanam di Nagari Koto Baru, Kecamatan Luhak Nan Duo, Kabupaten Pasaman Barat, Provinsi Sumatera Barat. Penelitian menggunakan bedengan berukuran 5,5 x 11,0 m dengan jumlah populasi 150 tanaman dengan 6 ulangan. Pengamatan meliputi insidensi penyakit (%) dan severitas penyakit (%). Model kurva perkembangan penyakit (temporal) diuji dengan model: logistic, monomolecular, dan exponential. Pola penyebaran penyakit (spatial) dianalisis dengan run dan diuji dengan uji Z: aggregate, regular, dan random. Hasil penelitian mendapatkan: Model kurva perkembangan (temporal) penyakit layu Stewart pada dua periode tanam yang berbeda adalah sama yaitu monomolecular dan Pola penyebarannya (spatial) juga sama yaitu random.

Abstract

Bemisia tabaci is a major pest in chili as it can act as a vector for transmitting the yellow curl virus. Endophytic bacteria have been reported to trigger plant defense against whiteflies. This study aimed to obtain a solid formula for the endophytic bacteria B. pseudomycoides strain SLBE1.1SN and a storage duration that effectively controls whitefly. This experimental study used a completely randomized design (CRD) consisting of 26 treatments and repeated three times. The treatments combined different types of endophytic bacterial carrier formulas and storage duration, synthetic insecticide treatment (Imidacloprid), and control. The treatments were applied to chili seeds and seedlings. The results showed that not all stored endophytic bacterial formulation could suppress the whitefly population on chili plants. The formula B. pseudomycoides strain SLBE1.1SN with rice straw as carrier material at six weeks storage was the best formula for controlling whitefly. This suggests that the formulation of stored endophytic bacteria not only reduced the number of eggs laid, but also suppressed the development of nymphs and imago.
