Abstract

The purpose of the research was to obtain the superior Trichoderma that had ability to colonize root with the resultbeing effective to supress Fusarium wilt desease and promote banana seedling growth. This experiment consistedof 2 factors and 4 replications. The first factor was Trichoderma spp. namely : A. Trichoderma koningii strain S6sh(TK-S6sh), B Trichoderma viride strain T1sk (TV-T1sk) and Trichoderma harzianum strain S10sh (TH-S10sh). Thesecond factor was the kind of banana namely a.Cavendis, b. Barangan and c. Kepok. The observation werecolonization ability, Fusarium wilt desease development and the banana seedling growth. The result showed thatTV-T1sk was the best spesies to colonize all banana seedling root. The highest colonization in Barangan bananaseedling root reached 80%. Trichoderma colonization in banana seedling root could suppress Fusarium wilt diseasedevelopment and increase banana seedling weight. Higher ability of Trichoderma to colonize banana seedling rootcaused lower disease incidence of Fusarium wilt and greater biomass of banana seedling. Interaction betweenTV-T1Sk and Barangan banana was the best in colonization, so they were effective to suppress Fusarium wiltdesease and increase banana seedling biomass.

Abstract

Study on diversity of aquatic insects in rice is important to determine the condition of the rice fields. The purpose of this research was to study the community of aquatic insects in two difference cultivations (organic and conventional) and sub districts (Koto Tangah dan Pauh) in Padang City. Purposive random sampling method was used. Samples were collected by using water insect nets and water bottle traps. The results showed that the aquatic insects found in the study site consisted of 5 orders (Coleoptera, Diptera, Ephemeroptera, Hemiptera, Odonata), 16 families, 51 species and 3808 individuals. Aquatic insect populations in organic farming was higher (5 orders, 15 families, 48 species and 3089 individuals) than conventional (4 orders, 9 families, 20 species and 719 individuals). Aquatic insects found were acting as predators (3718 individuals), detrivors (7 individuals), and omnivors (83 individuals). The diversity indexes of aquatic insects on two locations were classified as medium but the diversity in organic cultivation was higher than conventional.

Abstract

Rhizobacteria is an alternative biocontrol of Fusarium verticillioides Sacc. Nirenberg caused ear rot on maize. The aim of this study was to screen rhizobacteria isolates that had ability as antagonist agent against F. verticillioides in vitro. Rhizobacteria was isolated from rhizosphere of healty maize from two villages of West Pasaman. Twenty six rhizobacteria isolates were obtained, then tested for hypersensitive reaction (HR), pectinase enzyme production, initial inhibitory activity, and hemolytic test. Two selected isolates: RBPas1 10-6 1 and RBPas2 10-5 2 could inhibit the growth of F. verticillioides. The inhibitory activity of both isolates were observed with dual culture method, using complete random design (CRD) with 2 treatments and 5 replications, furthermore physiological characterization was conducted. RBPas1 10-6 1 and RBPas2 10-5 2 isolates had the percentage inhibition of micelial growth: 46.16% and 31.30% respectively. Physiological characterization showed that RBPas1 10-6 1 was gram negative with baciliform cells, produced chitinase enzyme, siderophores and fluorescent. RBPas2 10-5 2 was gram positive with bacilliform cells, did not produce chitinase enzyme, siderophores and fluorescent.

Abstract

Golden snail is an important pest on rice plants in Indonesia. The study purposed to obtain the most effective plant extracts to suppress the golden snail population. The study was conducted at the greenhouse of Faculty of Agriculture, Universitas Andalas, Padang from November to December 2018, using a Completely Randomized Design (CRD) with six treatments and four replications. The treatment was leaf extracts from several plants with a concentration of 10 g/l, that were god’s crown or mahkota dewa (Phaleria macrocarpa), noni or mengkudu (Morinda citrifolia), breadfruit or sukun (Artocarpus altilis), ti plant or andong (Cordyline fruticosa), mangkokan (Nothopanax scutellarium), and control. The parameters observed were mortality of golden snails, percentage of clumps attacked, and intensity of golden snail attacks. The results showed that there were three leaf extracts could suppress golden snail population significantly, ie. Mangkokan, andong and mahkota dewa. The mangkokan leaf extracts was most effective in controlling golden snails which caused mortality of golden snails to reach 100% within 24 hours of exposure so that they did not attack the clumps as a whole.

Abstract

Tungro disease is one of the obstacles to increasing national rice production. The use of resistant varieties is a component to control the virus that is environmentally friendly and easily accepted because it does not require additional costs. This study aimed to determine the resistance of nine rice varieties commonly planted by farmers against the tungro. The study was conducted in a greenhouse, and the source of the tungro virus inoculum was taken from the Lintau area of ??West Sumatra Province. The results showed that of the nine varieties tested, IR 42 was resistant to the tungro attack, seven others were classified as moderate, and one variety was classified as vulnerable. The moderate resistant varieties were Anak Daro, Cisokan, Cantik Manih, Saganggam Panuah, Junjuang, Kuriek Kusuik, and Caredek Merah. In contrast, the variety that classified as vulnerable was Batang Sungkai due to the symptoms of attack more clearly than on other varieties, the fastest of a period of symptoms appear (10.15 days), the highest disease incidence (80.62%) with a disease index of 7.65.
