Abstract

Pokahbung was one of some problems in Sugarcane cultivation. This experiment was aimed to test antagonist agent (Trichoderma sp and Gliocladium sp. ) to control Fusarium moniliforme. This study was conducted at screen house,at Agriculture Faculty, Universitas Sumatera Utara, Medan from March to October 2016th. It was done by using Completely Randomized Design (CRD) factorial with two factors and three replications. First factor was using antagonist agent (Trichoderma sp, Gliocladium sp., and combination of  Trichoderma sp. and Gliocladium sp.) and the second factor was the concentration of antagonist agent 106 , 105, 104. The result showed: the best treatment was combination of  Trichoderma sp. and Gliocladium sp. and with concentration 105and 106. Keywords: sugarcane, Fusarium moniliforme, Trichoderma sp., Gliocladium sp..

Abstract

The objective of the research was to study biology of the Elaeidobius kamerunicus (Coleoptera:Curculionidae) on the oil palm plants in the highlands areas. The research was conducted at PT Perkebunan Nusantara IV Bah Birung Ulu and Laboratory of Plant Pest and Disease Indonesian Oil Palm Research Institute (PPKS) Marihat from November 2016 to April 2017. It was done using by descriptive method. The results showed that the life cycle of E. kamerunicus was 18.6 ± 3.05 days, egg phase, 2.33 ± 0.57 days, the first instar larvae,  2 ± 1.73 days, the second  instar larvae, 5 ± 1 days, and the third instar larvae, 2.66 ± 1.15days and the pupa  4.66 ± 0.57 days. Age of male, 10.72 ± 1.4 days faster than female 14.44  ±1.35 days. Preoviposition period was 2 ± 0 days, while oviposition  9.84 ± 0.96 days, and post oviposition 4 ± 0.89 days. The number of eggs laid by a female during her lifetime was 20.4 ± 2.6. Keywords: Elaeidobius kamerunicus, biology, oil palm, highland areas.
