Abstract

Tagetes erecta Linnaeus is classified as a nematisidal plant so that it can control root-knot nematodes (Meloidogyne spp.). The purpose of this study was to determine the dose of T. erecta leaf powder, which was effective in controlling root-knot nematodes (Meloidogyne spp.) on tomato. This study used a Completely Randomized Design (CRD) with six treatments and four replications, namely the effectiveness of several doses of T. erecta leaf powder (control/ no treatment, 5 g, 10 g, 15 g, 20 g, 20 g, 25 g each 5 kg of soil). The results showed that the application of T. erecta leaf powder reduced the amount of root-knot, number of eggs and groups of eggs and the number of nematodes in the soil. The most effective dose was 20 g/ 5 kg of soil.

Abstract

Fusarium wilt diseases caused by Fusarium oxysporum f sp cubense (Foc) is the most important diseases on banana in the world. Once Foc is present in the soil, it cannot be eliminated. The aim of research was to evaluate the potential of Pseudomonad fluorescens indigenous to control Fusarium wilt in planta. This experiment was arranged by completely randomized design with 17 treatments and 10 replications. Sixteen isolates of P. fluorescens indigenous had been successly taken from several different cultivars of banana rhizospheres at endemic area of Fusarium wilt in the centre of banana production in West Sumatra that were introduced to banana seedlings cv Cavendish inoculated with Foc. The variable observed were incubation period, percentage of leaf infection, discoloration of pseudostem and the intensity of damaged corms. The result showed that The PfCvP1 isolate (from rhizosphere of Cavendish at low altitude area) was the most effective to inhibit the development of Fusarium wilt: 97.89 % (prolong incubation period), 67.26 % (reduced infected leaves), 63.63 % (reduced damaged corm), and 72.62 % (reduced disclorotion of pseudostem) and increased plant growth.

Abstract

Oryctes rhinoceros Linnaeus is one of the main pests of oil palm plants. The Oryctes rhinoceros control of being commonly used is synthetic insecticides. However, it is unwise useable to cause negative impacts on humans and the agricultural environment. Therefore, an alternative insecticide that is safer and environmentally friendly is needed, such as tuba root (Derris elliptica Benth.). The research was conducted in a Plant Pest laboratory, Faculty of Agriculture, University of Riau, Pekanbaru, from July to August 2018. This study aims to obtain an effective concentration of tuba root extract to control Oryctes rhinoceros larvae. The research was conducted experimentally using a Completely Randomized Design (CRD), which consists of five treatments and four replications. The treatment used is the concentration of tuba root extracts 0 g.l-1 of water, 25 g.l-1 of water, 50 g.l-1 of water, 75 g.l-1 of water and 100 g.l-1 of water. The result in them showing that the application of tuba root extract at a concentration of 75 g.l-1 was able to decrease O. rhinoceros larvae population with a total mortality of 82.5%. The lethal concentration to kill 50% of O. rhinoceros larvae population was 1.0% or equal to 10 g.l-1 of tuba root extract, while the lethal concentration to kill 95% of O. rhinoceros larvae population was 30.6% or equal to 306 g.l-1 tuba root extract.

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.
