Abstract

The application time of Paecilomyces spp. was assumed affecting its ability to suppress the root knot nematode (Meloidogyne spp.). This study aimed to get the effective application time to suppress Meloidogyne spp. The study was carried out at greenhouse and Biological Control Laboratory of Faculty of Agriculture, University of Andalas from March to June 2015. The research method used was compeletely random design (CRD) with 5 treatments and 4 replications. The application times consisted of 14 days before planting, 7 days before planting, at planting time, 7 days after planting, 14 days after planting and control. Application time of Paecilomyces spp. on 7 days before planting was the best time to reduce the number of root knot, the group of nematode eggs, nematode eggs and nematode larvae in the soil.

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

Ginger rot disease caused by Fusarium oxysporum f. sp. zingiberi is difficult to control because the pathogen is soil borne and is able to form clamidospore as resting structure. The aim of this study was to obtain indigenous antagonistic fungi from ginger rhizosphere which is potential for suppressing the growth of F. oxysporum f. sp. zingiberi. Fungi isolated from ginger rhizosphere were subjected for antagonism assay using dual culture method. Fungi isolates showed capability to inhibit F. oxysporum f. sp. zingiberii were then identified based on morphology characters. Eleven isolates were successfully isolated, but only 9 isolates showed the potentials of suppressing the growth of F. oxysporum f. sp.  zingiberi. All 9 isolates i.e. AB4, GC1, BB1, AB1, AB2, K12, GC3, K11 and GC2 had antibiosis activity, and 3 isolates among them i.e. AB2, BB1 and K11 showed competition mechanism. Based on morphology characters the isolates were identified as Penicillium spp. (4 isolates), Trichoderma spp. (3 isolates), and Aspergillus spp. (2 isolates).

Abstract

Pengendalian hama dan penyakit tanaman sayuran ramah lingkungan menggunakan agens hayati sampai saat ini masih belum dilaksanakan oleh petani. Agar penggunaan teknologi pengendalian hama dan penyakit tanaman sayuran secara hayati bisa dilaksanakan oleh petani di Alahan Panjang, maka pada kegiatan kedua setelah survei dilakukan kegiatan penyuluhan. Kegiatan penyuluhan telah dilaksanakan pada hari Sabtu, tanggal 23 Juli 2016. Materi utama yang diberikan adalah tentang hama dan penyakit tanaman sayuran, pengendalian hama secara terpadu, penggunaan ekstrak tumbuhan untuk pengendalian hama dan penyakit sayuran, penggunaan agens hayati untuk pengendalian OPT sayuran, pemanfaatan limbah sayuran sebagai kompos dan perbanyakan massal agens hayati (Beauveria bassiana, Trichoderma sp). Kegiatan penyuluhan ini dihadiri oleh 20 orang petani yang merupakan anggota kelompok tani Harapan Baru dan Agribisnis. Petani yang hadir merupakan petani yang menanam sayuran dan belum pernah menggunakan agens hayati untuk pengendalian hama dan penyakit sayuran. Terkait dengan penyediaan mikroba sebagai agens hayati dan dekomposer, maka pertemuan selanjutnya adalah cara perbanyakan Beauveria bassiana dan Trichoderma pada media PDA dan berbagai substrat serta penggunaan Trichoderma sebagai dekomposer. Pada kegiatan pengabdian ini, selain dari kegiatan penyuluhan dan pelatihan, juga dilakukan praktek lapang. Kegiatan praktek lapang yang dilakukan adalah berupa pemanfaatan kompos yang diperkaya dengan Trichoderma hasil buatan petani sendiri. Kompos dari berbagai jenis limbah langsung diaplikasikan pada bedengan sebelum penanaman tanaman sayuran. Praktek lapang pemberian kompos dan agens hayati dilaksanakan menggunakan tanaman bawang merah. Praktek lapang ini bertujuan untuk melihat kemampuan agens hayati ini dalam menekan serangan hama dan penyakit bawang merah.
