Abstract
Celery (Apium graveolens L.) is an important spice plant cultivated in the highlands. One of the diseases that can reduce the production of celery is root ringworm caused by the parasitic nematode Meloidogyne sp. Until now, nematode control uses pesticides which are toxic and have a negative impact on the environment. Currently, many biological control efforts have been developed, one of which is the use of endophytic bacteria. The purpose of the study: to determine the potential of endophytic bacteria from the wetlands of South Kalimantan as biological agents for the root-knot nematode Meloidogyne sp in celery plants. The research was carried out in three stages, namely: exploration of endophytic bacteria in the wetlands of South Kalimantan in November 2021, the in-medium test to be carried out at the Plant Health Laboratory, Faculty of Agriculture, National Development University "Veteran" East Java in December 2021 and the in planta test in Sumber Kembar Desa Hamlet. Sumber Glagah, Pacet, Mojokerto in December 2021 to March 2022, using a completely randomized design. Then, further DMRT test was carried out with a level of 95%. The results showed that as many as 9 isolates of endophytic bacteria from the wetlands of South Kalimantan which had been tested for their biosafety were able to increase the mortality of juvenile-II nematode Meloidogyne sp. with the highest mortality percentage, namely 50.67%, 45.33%, 49.33%, and 45.33% at 12 hours after treatment. Treatment of endophytic bacteria on celery plants can inhibit the attack of root-knot nematodes. Seen in the lowest gall index parameter is 2.33%. The lowest gall number parameter was 19.67/gram root and the lowest nematode population parameter was 9.33/gram root and the lowest nematode population was 11.33/10 gram soil Keywords: Endophytic Bacteria, Meloidogyne, Celery
