Abstract

Plant parasitic nematodes can cause crop losses in celery. Parasitic nematodes that infect celery are Helicotylenchus spp., Trichodorus, Longidorus, Xiphinema and Meloidogyne spp Cropping pattern becomes part of the factors that influence the presence of plant parasitic nematodes in celery. Field obervation was conducted in celery growing areas to study the diversity and abundance of parasitic nematodes from monoculture and polyculture cropping system. Seven genus of nematodes, i.e. Meloidogyne, Pratylenchus, Tylenchorhinchus, Tylenchulus, Xiphinema, and two nonparasitic nematode were identified from polyculture cropping system, whereas 4 genus were found from monoculture cropping system i.e. Meloidogyne, Pratylenchus, Tylenchulus and Trichodorus. Genus with high abundance in polyculture cropping pattern was Xiphinema and Meloidogyne however Trichodorus was not found. Genus with a high abundance in monoculture was Meloidogyen and Xiphinema was not found. The genus most frequently found was Meloidogyne in polyculture and Xiphinema in monoculture.

Abstract

ABSTRACT Wild rice Oryza rufipogon accession can be used as a source of resistance genes to develop elite rice varieties for Rice tungro virus. This study aimed to examine some potential high yield rice lines developed by crossing IR64 with O. rufipogon for their response to three isolates of Rice tungro virus originating from Bogor, Sumedang, and Bali. Virus transmission was done by insect vector, Nephottetix virescens. Variation on plant response was observed. Three lines i.e. Bio5-AC-Blas/BLB, Bio62-AC-Blas/BLB-03, Bio111-BC-Pir7, showed stabile resistance response to all isolates of Rice tungro virus; 6 lines i.e. Bio132-AC2-Blas, Bio138-AC2-Blas, Bio148-Mamol-Dro, Bio154-Mamol-Dro, Bio159-Mamol-Dro, Bio 153-Mamol-Dro were moderately resistance. Virus isolates from Sumedang and Bali is more virulence than isolate from Bogor based on observation on incubation period, disease severity and suppression of plant height.

Abstract

Anthracnose caused by C. capsici is the most important factor causing low yield on chili in Indonesia. A research was conducted to examine to examine the potential of patchouli oil in suppressing anthracnose disease development on chili. In vitro test was conducted by growing C. capsici on potato dextrose agar (PDA) medium that has been added with different concentration of patchouli oil, i.e. 10, 5, 2.5, 1.25 and 0.625%. Negative controls treatment (Kn) was conducted by growing C. capsici on PDA without patchouli oil, whereas positive controls (Kp) was conducted by growing C. capsici on PDA containing mancozeb fungicide. Patchouli oil -A significantly suppressed the growth of C. capsici compared to patchouli oil-B on 10 days after harvest, i.e. 91.15% suppression for all concentration level except for 0.625% which caused 85.92% suppression. Further examination using patchouli oil-A showed that incubation period on curative test was 8 days after inoculation (DAI) whereas on preventive and induced resistance test were 5 DAI. Disease severity at 10 DAI reached 4.8%, 23.20%, and 29.60% on curative, preventive, and induced resistance tests, respectively. Disease severity was 29.60% and 68.80% on positive control and negative control, respectively.

Abstract

Budok caused by Synchytrium pogostemonis is the important and destructive disease on patchouli plant (Pogostemon cablin). Chemical control must be done in incidence with high disease intensity and prediction of outbreak. The experiment was done using benomyl (Benlate 50 WP) and cuprous oxide (Kocide 77WP) 0.1%, 0.2% and mixture of both ( 1 g cuprous oxide and 1 g L-1 benomyl). Patchouli plant was sprayed eight times with one week interval. Harvesting was done two weeks after the end of spraying. Residue analysis of Cu was done with AAS and benomyl residue with HPLC. The result showed that 0.1% benomyl significantly reduced the disease intensity. The other treatments showed lower result. Harvested patchouli plants treated with 0.1% benomyl showed higher yield compare with 0.2% benomyl and cuprous oxyde. Cu residue in dried leaves was between 460 ppm and 950 ppm. Residue of benomyl was 54–100 ppb. Diseased seedling still can be used after spraying by benomyl four times with 2 weeks interval.

Abstract

The rapid development of oil palm industry is indicated by wide monoculture plantation. This condition causes the development of many diseases such as basal stem rot, bud rot, leaf spot, anthracnose, and fruit rot diseases. Recently, a new disease causing dry frond symptom was reported from plantations in 2 provinces, i.e. East Kalimantan and North Sumatera. Disease exploration was conducted in Muara Wahau estate, East Kalimantan and Kota Pinang (Labuhan Batu) estate, North Sumatera. Typical symptoms involved decaying which started from the tip of frond that spread into the middle, rotting brown to blackish; when rot had reached the middle, the frond becomes dry, and finally broken. Isolation and identification of the fungi from the infected plant showed the association of Thielaviopsis sp., although Koch Postulate–based assay was unable to prove that the disease was caused by infection of Thielaviopsis sp.
