Abstract

The potential of rhizosphere fungi from health cayenne pepper plant (Capsicum frutescens L.) from Bumbungan Village to control the wilt disease Fusarium in vitroThe objectives of the research were to find out the potential and level domination (prevalance) of rhizosphere fungi from health cayenne pepper plant (Capsicum frutescens L.) to control the wilt disease Fusarium. It was done by using the in vitro inhibition test of rhizophere fungi againts the Fusarium oxysporum f.sp. capsici with dual culture technique. The study included 1) rhizosphere soil sampling of health cayenne pepper plants; 2) isolation and identification of soil fungi; 3) isolation of the pathogen Fusarium oxysporum f.sp capsici; 4) purification of pathogenic isolates of Fusarium oxysporum f.sp capsici; 5) prevalence of fungal isolates; 6) testing the inhibition of rhizosphere fungi on the growth of the fungus Fusarium oxysporum f.sp. capsici. The result showed that the identified rhizosphere fungi were the genus of Aspergillus spp., Penicillium spp., Trichoderma spp. The prevalence of fungi in the rhizosphere that dominate the healthy cayenne pepper plant is the genus of Penicillium spp. and Aspergillus spp. which have the same prevalence rate of each, 42.1 %. while the fungus Trichoderma spp. has prevalence rate 15,8 % . The results showed that all the rhizosphere fungi have potential to control wilt disease Fusarium oxysporum f.sp. capsici with different levels of inhibition. Based on the results of this study, further research needs to be done in order to apply directly the identified antagonist fungi to plant that already affected with wilt diseas

Abstract

Identification of Fusarium solani Fungi Associated with Stem Rot Disease in Dragon Fruit Plant (Hylocereus sp.) at Bangorejo District, Banyuwangi Regency Dragon fruit plants at Banyuwangi in the maintenance process always experience disorder such as pathogenic attacks. The part of dragon fruit plant whichis often attacked by pathogens is the stem which is caused the stem to rot. One type of photogenic fungus in dragon fruit plants is Fusarium solani. This fungus attacks the stem of the dragon fruit plant, so that it can cause the stem of the plant looks wilted and brown rot.The cause of stem rot disease of dragon fruit plant in Banyuwangi is not yet known exactly, thus identification in macroscopic, microscopic, and molecular need to be done. Recently, the use of molecular methods in fungi identification has increased to solve this problem. One of the molecular approaches to identify fungi is by using a device called Polymerase Chain Reaction (PCR).The result of this research showed mycelium that grown on PDA media (Potato Dextrose Agar) shaped like a thick cotton expands like a cloud, the shape of the edge of the colony is uneven, the surface color of the colony is white, the color of the bottom of the colony is white, the direction of the growth of the mycelium is to the side and the structure of the mycelium is smooth. In microscopic identification there found a long macroconidia, crescent shaped with blunt ends, 1-5 septa, microconidia shaped in round to oval, long hyphae and bersepta. The molecular identification with PCR to determine the presence of Fusarium solani mushroom by using universal primary pairs of ITS4 and ITS5 successfully amplified and produced DNA fragments measuring 560 bp.

Abstract

ABSTRACT Effectiveness of Technique Extraction Test and Dry Heat Treatment to Seed Health of Chili Pepper (Capsicum frutescens L.). Chili (Capsicum frutescens L.) is one of the horticultural crops of the Solanaceae family that has a high economic value. Seed healty problems is one of the chili pepperproduction constraints. Chili seeds used by farmers mostly contaminated by seed-borne diseases such as viruses. This study aims to determine the effectiveness of seed extraction techniques and Dry Heat Treatment (DHT) in producing healthy red pepper seeds in a seed source trials of healthy plants and diseased plants. The design used in this research is completely randomized design (CRD) with 2 factors. The first factor was the extraction technique which consisted of three levels ie extraction technique using 2% HCl, extraction techniques using quicklime and extraction techniques using water. The second factor was DHT with 2 levels ie DHT and without DHT (NDHT). The results of this research showed that DHT treatment was effective in producing healthy chili pepper seedlings with healtinese 100%, while seed extraction techniques has not been effective to produce healthy red pepper seeds with a percentage of less than 90%. Interaction between extraction techniques and DHT on trial seed originating from sick plants showed real influence. Keywords: chili pepper, extraction techniques, Dry Heat Treatment, healthy seed
