Abstract

The Effective Test of Plant Extracts as A Nematicide for Fecundity of Root Knot Nematodes (Meloidogyne spp.) in Celery Plant (Apium graveolens L.) at Greenhouse. Root knot nematodes Meloidogyne spp. is among the harmful organism in plant cultivation, one of which is in the celery plant. Nematodes caused drop in/reduced plant productivity and plant quality, it can even lead to death and crop failure. Base on the adverse effects of nematodes attack, it must be anticipated. Biopesticides is one of the alternatives that can be used to suppress the growth of nematodes and more environmentally friendly. The purpose of this study is to know the effectiveness of the plant extracts that suppress the number of egg mass, the number of eggs per egg mass and the number of adult females in 1 g of roots. This study using a completely randomized design (CRD), with 5 types of treatments and each treatments received 5 repetitions. The treatments are by giving each plant extracts of 100 cc per pot. The result showed that the extract of marigold plants (Tagetes spp.) has the highest effectiveness, with the percentage of emphasis on the number of eggmass in 1 g roots is 99%, the emphasis on the number of eggs per eggmass in 1 g roots is 84,6% and the emphasis on the number of adult females in 1 g roots is 99,4%. While extract of sour-plant showed that has the lowest effectiveness, with the percentage of emphasis on the number of eggmass in 1 g roots is 96,68%, the emphasis on the number of eggs per eggmass in 1 g roots is 60,72% and the emphasis on the number of adult females in 1 g roots is 98,44%.

Abstract

Testing the Effectiviness of Plant Extracts as Botanical Nematicides to Suppress the Population of Root Knot Nematodes (Meloidogyne spp.) on Celery Plants (Apium graveolens L.). Root knot nematodes (Meloidogyne spp.) are one of nematodes that attack various types of important agricultural crops. This nematode is found on plant roots and can cause symptoms such as stunting, root knot, and wilting in plants. One effort to control nematodes is to use botanical nematicides. Based on this, research will be carried out to suppress the population of root knot nematodes (Meloidogyne spp.) using plant leaf extracts of Marigold (Tagetes spp.), soursop (Annona muricata L.), papaya (Carica papaya L.), neem (Azadirachta indica), and jatropha plant (Jatropha curcas L.). The research methods are: (1) Making plant leaf extracts, (2) Making solution of Meloidogyne spp., (3) Testing the ability of several plant leaf extracts in pots/polybag. The purpose of this study was to determine the plant leaf extracts were able to suppress the population of Meloidogyne spp. The results showed that the nematode population/300 g soil, Tagetes spp. extracts was the best in suppressed the population, 22,2 mesh (75,3%), Jatropha curcas L. 25,4 mesh (71,7%), Carica papaya L. 28,0 mesh (68,8%), Azadirachta indica 31,6 mesh (64,8%), dan Annona muricata L. 34,0 mesh (62,2%). In calculating the nematodes population/1 g of root, it is Tagetes spp. the best extract suppressed the population of root knot nematode, namely 21,2 mesh (69,5%), Jatropha curcas L. 24,0 mesh (65,5%), Carica papaya L 27,4 mesh (60,6%), Azadirachta indica 30,8 mesh (55,7%), dan Annona muricata L. 33,4 mesh (52,0%).
