JENIS NEMATODA YANG DITEMUKAN PADA TANAMAN BAWANG MERAH (Allium ascalonicum) DAN RHIZOSFER SEKITARNYA DI AREA PERSAWAHAN NITEN, BANTUL, YOGYAKARTA
ABSTRACT: Constraints in the
development of onion plants are plant parasitic nematodes attack. The damage
could reach 30% or greater. This study aims to determine the type of plant
parasitic nematodes found in onion crops in the area and the surrounding onions
fields rhizosfer at Niten, Bantul, Yogyakarta.
Isolation of nematodes from roots and leaf tissues of onion used the
method of Method Spray funnel and isolation from soil using a modified Baermann
funnel. Samples of soil, roots and leaves of onion taken at random from five
different locations, each location 20 samples taken. Isolation results are
stored in a bottle. Identification of nematodes using identification book
Pictorial Key to Genera of Plant Parasitic nematodes.
From the results
obtained from samples of soil
nematodes and roots.Nematodes obtained which consists of four species of Meloidogyne sp., Helicotylenchus sp., Scutellonema sp., and Saprofage sp. Nematodes
recovered from soil samples consisted of three species, namely: Helicotylenchus
sp., Scutellonema sp., and Saprofage sp . While the roots are found from the
sample is composed of two species: Meloidogyne sp. and Saprofage sp .. From
these results which are parasitic Meloidogyne sp., Helicotylenchus sp., and Scutellonema sp.
while Saprofag sp. not parasitical.
