Abstract

Chili is an important horticultural crop that is cultivated in large quantities every day. However, production is often disrupted by diseases, one of which is anthracnose caused by the fungus Colletotrichum spp. Environmentally friendly control can be done with natural ingredients such as babadotan extract which contains antifungal compounds such as steroids, terpenoids, phenols, saponins, fatty acids and alkaloids. This research aims to test the ability of babadotan (Ageratum conyzoides L.) leaf extract to suppress the growth of Colletotrichum spp. in vitro. The research took place at the Phytopathology Laboratory, Faculty of Agriculture, Lambung Mangkurat University from October 2023 to May 2024. The method used RAL with 5 treatments and 4 replications. The results showed that BCE treatment (9% babadotan leaf extract) had the lowest growth inhibition at 40.02%, while BCB (3%) 34.94%, BCC (5%) 22.39%, and BCD (7%) 8.52%.

Abstract

Celery plants (Apium graveolens L.) have export value and are included in the important leaf vegetable group. Disturbances caused by plant-disturbing organisms in celery cultivation are still a problem that is always faced by farmers. The pest that is often found infecting celery plants, especially in the Landasan Ulin Utara area, Liang Anggang District, Banjarbaru City, South Kalimantan Province, is the Root Knot Nematode (NPA) (Meloidogyne spp). The symptoms of this NPA attack are very typical, namely the roots become swollen because nematode attacks the root system and disrupts the root tissue. Therefore, before causing greater losses, it needs to be anticipated. Control can be carried out by means of biofumigation, namely using bitter mustard greens waste which comes from the Brassicae family because it contains glucosinolates (GSL) and isothiocyanate compounds (ITS). This research aims to determine whether biofumigants from chopped bitter mustard greens are effective in controlling Meloidogyne spp. on celery plants. This research used a one-factor Completely Randomized Design (CRD) method, namely treatment with 500 Meloidogyne spp eggs. (control/T0) and 4 treatments with chopped bitter mustard greens, namely 500 Meloidogyne spp. + 200 grams of chopped bitter mustard greens (T1) 500 eggs of Meloidogyne spp. + 400 grams of chopped bitter mustard greens (T2) 500 eggs of Meloidogyne spp. + 600 grams of chopped bitter mustard greens (T3) and 500 Meloidogyne spp eggs. + 800 grams of chopped bitter mustard greens (T4). The results of this study show that celery plants treated with T4 can reduce disease severity and the average number of NPA populations. The highest disease severity was found in T0 plants with a percentage of 45.0% and the lowest percentage was in T4 treatment plants at 4.2%. The highest NPA population was also found in T0 plants, namely 428,125 individuals and the lowest population was in T4 plants, amounting to 126,125 individuals.
