Abstract

A study of dosage and frequency of casting (earthwarm excrement) for controlling fusarium wilt disease (Fusarium oxysporum f.sp lycopersici) on tomatoes (Lycopersicum esculentum Mill) has been done in a Laboratory of Plant and Disease Department and a Field Experiment Station, Agriculture Faculty, Syiah Kuala University in Banda Aceh. The purpose of this experiment was to study effects of dosage and frequency of casting to control fusarium wilt on tomato plants. The experiment applied a factorial completely randomized design (CRD) with five replications. The factors studied were dosage and frequency of kascing. The dosage consisted of 100 and 200 g/plant, whereas the frequency of kascing consisted of one and two times of application. The results showed that dosage of 200 g/plant with two times of kascing application can control disease fusarium wilt on tomato plant.

Abstract

The Use of Antagonistic Bacterial as Biocontrol Agents to Wilt Disease (Fusarium oxysporum f.sp.cubense) on Banana Susanna Jurusan Hama dan Penyakit Tumbuhan Fakultas Pertanian Universitas Syiah Kuala Banda Aceh ABSTRACT             Fusarium wilt or panama disease caused by Fusarium oxysporum f.sp. cubense is on of the important disease on banana. Recently there is no such effective methode for controlling the disease. The use of fungicide to control the disease can make new races of the fungal pathogen is very virulent.  The use of biocontrol agent such as Pseudomonas fluorescens and Bacillus subtilis is alternative methode to control fusarium wilt.  The aim of this experiment was to find out the most effective antagonist bacterial to control fusarium wilt on banana.  The study was carried out in Mycology Laboratory of IPB and green house and Phytopathology Laboratory of Balitbio, Bogor from January to October 2001.  Six treatments in this experiment were arranged in randomized complete design with 3 replications.  The result showed that Pseudomonas fluorescens and Bacillus subtilis were reducing Panama disease fusarium wilt on banana. Both antagonistic bacterials were effective to control fusarium wilt.

Abstract

Trichoderma is a free-living fungus, commonly can be found in soil and root ecosystem.  Extensively, it is capable of producing antibiotics, parasite to other fungus, and microorganism that cause diseases on plants.  The objectives of the experiment were to study effects of Trichoderma on germination and growth of cacao, tomato, and soybean. The result showed that provision of Trichoderma (T. harzianum and T. virens) conidia suspension using seed submersion technique did not affect seed germination of cacao, tomato, and soybean, but significantly affected cacao root extension. Provision of Trichoderma through seed submersion on sand box germination gave a positive response to tomato plant, tolerance to cacao plant, and a negative response to soybean plant.  The causing factors of difference responses varied including concentration, application techniques, and kinds of seed.

Abstract

The objectives of the study was to obtain an effective concentration of B. bassiana to control pests of N. Viridula.  Experiment was performed at Laboratory of Pest, Agriculture Faculty, Syiah Kuala University Darussalam, Banda Aceh. The experiment used a  faktorial completely randomized design (CRD).  Factors evaluated were (1) concentration of B. bassiana consisting of three levels: 2 gL-1 distilled water, 4 gL-1 distilled water, and 6 gL-1 distilled water, and (2) stadia of N. viridula consisting of 2 levels: third instar nymphs and imago. Variable observed were incubation period, mortality of N. viridula, time of death, and percentage of feeding inhibition. The results showed that concentration of B. bassiana and stadia of N. viridula had no effect on incubation period of fungus B. bassiana. Concentration of B. bassiana affected mortality and time of death of nymph and imago N. viridula. Concentration of fungus B. bassiana affected percentage of feeding inhibition. In general, fungus B. bassiana had a high potential on controlling insect N. viridula.

Abstract

The objectives of this research were to find out dosages of biofertilizer and manure which was the most effective to control bean fly (A. phaseoli). This research was carried out at Cot Cut Village, District of Kuta Baro, Aceh Besar, from September to December 2008. This research used a factorial randomized complete block design with two factors: biofertilizer (H) and manure (K).  Dosages of biofertilizer were H1= 2,8 L ha-1, H2= 3,5 L ha-1, H3= 4,2 L ha-1, and H4= 4,9 L ha-1. Dosages of manure fertilizer were K1= 2,8 ton ha-1,  K2= 5,6 ton ha-1 and K3= 8,4 ton ha-1.  The result showed that application of biofertilizer was more effective than that of manure fertilizer to percentage rates of the attacked plant. However, both biofertilizer and mature fertilizer exerted  significant effects to percentage of plant death, plant dwarf, number of larva and pupa, and dry seed weight per plant.  Application of biofertilizer at 4,9 L ha-1 and manure fertilizer at 8,4 ton ha-1 reduced  percentages of  plant death up to 86% and 83%, respectively.
