“…Penyakit terpenting pada bawang merah ialah busuk pangkal batang yang disebabkan oleh Fusarium oxysporum f. sp. cepae yang menyebabkan kerugian hingga 50% (Rahmiyati et al 2021) dan penyakit bercak ungu yang disebabkan oleh Alternaria porri (Wiyatiningsih et al 2009) yang menyebabkan kerugian mencapai 57% (Fahrun et al 2018).…”

Produksi bawang merah di Indonesia menghadapi permasalahan hama dan penyakit yang berat. Penggunaan pestisida menjadi andalan petani hingga saat ini untuk pengendalian hama dan penyakit tersebut. Beberapa agens biokontrol hama dan patogen bawang merah terbukti efektif secara individual, namun belum terintegrasi di lapangan. Tujuan penelitian ialah mengevaluasi kombinasi agens biokontrol dengan efektivitas terbaik untuk menekan insidensi penyakit utama bawang merah di lapangan. Percobaan lapangan dilakukan di Tegal, Jawa Tengah, salah satu sentra penghasil bawang merah di Indonesia. Perlakuan yang diuji ialah kombinasi Fusarium nonpatogenik (FNP) + plant growth promoting rhizobacteria (PGPR)+ khamir antagonis (KA), FNP + KA, PGPR + KA, FNP+PGPR, fungisida sintetik, dan tanpa perlakuan (kontrol). Penelitian disusun dalam rancangan acak kelompok dengan empat ulangan sebagai blok. Semua perlakuan kombinasi agens pengendali hayati dan fungisida sintetik menunjukkan perbedaan nyata dengan perlakuan kontrol dalam menekan penyakit busuk batang (Fusarium oxysporum f. sp. cepae) dan bercak ungu (Alternaria porri), tetapi tidak berbeda nyata antarperlakuan. Produktivitas bawang merah dengan perlakuan agens pengendali hayati memiliki bobot umbi segar yang cukup tinggi. Tanaman dengan perlakuan agens hayati PGPR + KA dan FNP + PGPR memiliki bobot umbi segar yang paling tinggi di antara perlakuan agens pengendali hayati lainnya. Penelitian ini menunjukkan bahwa aplikasi kombinasi agens pengendali hayati berpotensi menekan penyakit bawang merah di lapangan.

“…Klasmidiospores can germinate if there is root stimulation from sugar and amino acid compounds and also due to the accumulation of plant residues in the soil (Saputra, 2020). If the pathogen attack is not immediately controlled, resulting in a production loss of more than 50% (Rahmiyati et al, 2021).…”

Shallot (Allium ascalonicum L) is one of the horticultural plants that acts as a natural antioxidant. Shallot's productivity in Indonesia is relatively low. It is influenced by various factors, one of which is due to the attack of a soil-borne pathogen, namely Fusarium oxysporum. Symptoms of Fusarium oxysporum pathogen attack are yellow or pale green leaves and more elongated growth. Severe attack leads plant to death. Balanced fertilization and biopesticides application can prevent Fusarium wilt. This study aims to reduce and control Fusarium wilt disease. The research method used was the Split Plot Design method which consisted of two factors with the main plot, namely the application of suspension of microorganisms (S) which consists of two levels, namely fungicide application (S0) and Fobio application and the sub-plot, namely the application of various organic fertilizers (M) which consists of three levels, namely control (chemical fertilizer) (M0), chicken manure (M1), and Piensbio organic fertilizer (M2). Observation data for each treatment will be analyzed using analysis of variance (ANOVA) followed by the Duncan test (alpha 5%) if there were differences in each treatment. The results of this study, the main plot treatment, fungicide application (S0), showed an incubation period of 29 days and an average intensity of disease attacks of 4.2%. The treatment of subplots, a type of organic fertilizer (M), is unable to suppress the intensity of the attack and slow down the incubation period of the Fusarium sp on shallot crops. There was no interaction between the treatment of the main plots and the subplots on all the observation parameters.
