Abstract

The objective of the research was to inventarize pests and diseases that associate with Xanthosoma undipes K. Koch at Mount Karang, Pandeglang, Banten Province. The research was conducted at field of Xanthosoma undipes K. Koch at Mount Karang and Biotechnology Laboratory of Untirta in Serang from May until July 2015. Samples of the Xanthosoma undipes K. Koch were choosen by purposive sampling methods from several points around Mount Karang. Several types of pests, predators, and diseases were found in the cultivation field of Xanthosoma undipes K. Koch. The pests were mantises, grasshoppers, snout beetles, long-horned grasshopper, big eyes dragonfly, ants, cockroaches, spiders, and butterflies. The predators including parasites were ants, flies, stone flies, and crickets. Two diseases were found i.e. leaf blight caused by Phytophtora colocasiae and sooty mold disease caused by Capnodium sp. The study also revealed that pests and diseases were also found in the storage process (post-harvest). Some warehouse pests such as pillbugs, ants and mites were found. The disease found were stem rot disease caused by Sclerotium rolfsii and soft rot caused by Lasiodiplodia theobromae.Keywords: Xanthosoma undipes K. Koch, Pest and diseases

Abstract

ABSTRACTThe objective of the research is to investigate the effectiveness of soil solarization and antagonist bacteria in controlling fusarial wilt of banana.The experiment was conducted in farmer field by randomized complete block of two factors.  The treatment in the field, factor A is solarization (without solarization, three weeks of solarization, and four weeks of solarization); factor B is antagonist bacteria (without bacteria, bacteria 1, and bacteria 2). The treatment is replicated three times.  The number of banana’s plant for each treatments are 4-6 plants. The result of field research showed that single treatment of solarization, bacteria even combination between them did not significantly affect to suppress the incident of Foc.Keywords:  Fusarium oxysporum f.sp.cubense, soil solarization, antagonist bacteria

Abstract

Bacterial leaf blight disease is an economically important disease for the growth of rice plants. The research was aimed to know the most resistant varieties to bacterial (Xanthomonas oryzae pv. oryzae) in seedling phase. The research was conducted May up to Juli 2012 at Green House Livestock, Agriculture and Horticulture UPTD Serang city. The research used a Randomized Completely Blok Design (RCBD) with one factor, each one tray planted 3 varieties. Test varieties were planted in the middle, on the right was susceptible variety (IR-64) and to the left of the comparison resistant variety (Conde). Each variety was planted 10 seeds, so there were 30 rice stalks. There were 10 trays experiment, with 3 replications. Overall there were 30 trays trial. Results of research showed that from 10 varieties had tested, levels of resistance to bacterial leaf blight disease (BLB) in seedling phase were: (1) Waler 17,56 %, (2) Tambleg 18,46 %, (3) Kewal Bulu Hideng 20, 43 %, (4) Gadog 20,84 %, (5) Jaketra 21,58 %, (6) Kewal Cere 23,65 %, (7) Ketan Laleur 25,80 %, (8) Jalawara Hawara 26,29 %, (9) Ketan Solo 29,20 %, (10) Kewal Gudril 29,93 %. The fastest BLB incubation period was local variety of Kewal Gudril within 4-5 days.Key words : Local Varieties of Banten, Bacterial Leaf Blight, Xanthomonas oryzae pv. oryzae, Resistance and Disease Intensity.

Abstract

The aims of this study was to analyze the effects of biological fertilizers Trichoderma sp on the growth and yield of eggplant (Solanum melongena L.). The experiment used eggplant hybrid varieties and conducted in the village districts of Sekong village Rumingkang Cimanuk Pandeglang in Banten. Seven treatments of Trichoderma sp dose were tested in the experiment, namely 0g, 15g, 20g, 25g, 30g, 35g, and 40g / plant. The experiment used a randomized block design (RBD) and each treatment was repeated five times so that the total treatment unit was 35. Each polybag consisted of one plant. The results showed that the use of Trichoderma sp on various doses sp generate plant height, flower number, fruit number, fruit weight, fruit length, and dry weight was better than the plants that did not use the Trichoderma sp. The dose of Trichoderma sp was found best in T1 treatment with a dose of 15 grams/plant. Based on this study, further testing on Trichoderma sp. with higher dose and mixed with organic fertilizers is needed, as well as the need to do more research on plant diseases in eggplant (Solanum melongena L.).Key Words: Trichoderma sp., Biofertilizers, Purple eggplant

Abstract

This research aimed to find and identify isolates ofendophytic bacteria in banana plants root to suppress bacterial wilt disease in banana plants (Musa aradisiaca) This research has been carried out in the Laboratory of Agroecology Department Faculty of Agriculture, Sultan Ageng Tirtayasa Universityfrom December 2012 to April 2013.This research used a completely randomized design consisting of a single factor that endophytic bacteria consisting of 10 levels: control (without bacteria), bacterial endophyte 1, bacterial endophyte 2, bacterial endophyte 3, bacterial endophyte 4, bacterial endophyte 5, bacterial endophyte 6, bacterial endophyte 7, bacterial endophyte 8, bacterial endophyte 9. The treatment repeated 4 times. The parameter done are the percentage of inhibition, antagonism between endophytic bacteria test, test bacterial gram on endophytic bacteria, and bacterial morphology. This researchindicated,that all bacteria hada potential antagonist to inhibit Ralstonia solanacearum. Of the 60 isolates, 30 isolates showed the ability to inhibit the growth of Ralstonia solanacearum in vitro. Totally of 9 isolates were selected as candidates obtained antagonist belonging to Bacillus sp. Three isolates that had the best inhibitory ability against Ralstoniasolanacearum were BE 10-812, 10-8 BE 13, and BE 10-8 29. These three isolates were identified as Bacillus sp.
