Abstract

Stem Canker: A New Disease of coffee in LampungStem cancer is a new disease that has attacked smallholder coffee plantations in Lampung since 2010. The cause of the disease was unknown. This study aims to describe the symptoms of the disease, the incidence of the disease in the affected plantation, and identify morphologically and molecularly the canker pathogens of the coffee stem canker diseases. All stages of Koch’s postulate were carried out in laboratories and greenhouses. The isolated pathogens were morphologically characterized by colony shape and color as well as the conidia shape and size. Molecular identification was carried out by using a general primer (ITS1 and ITS4) and followed by sequencing. The main symptoms of the disease are stem cancer and dieback, as well as more infecting older plants. Pathogen of the coffee stem canker disease that attacks coffee plants in Lampung has been identified as Fusarium solani which has 99% homology with F. solani KY245947.1.

Abstract

Karat putih merupakan salah satu penyakit penting pada tanaman krisan di Indonesia. Teknologi yang efektif untuk pengendalian penyakit ini di Indonesia tidak tersedia. Penelitian ini bertujuan menguji potensi lima galur (Pseudomonas diminuta P14, Bacillus firmus J8, Lysinibacillus fusiformis C71, AKBR, AKS) plant growth promoting rhizobacteria (PGPR) untuk pengendalian penyakit karat putih yang disebabkan Puccinia horiana pada tanaman krisan di lapangan. Formulasi komersial Pseudomonas fluorescens dan Bacillus polymyxa dipilih sebagai pembanding. Percobaan dilakukan di lapangan dengan mengaplikasikan suspensi rizobakteri pada tanaman krisan. Semua galur PGPR yang diuji mampu menekan insidensi dan keparahan penyakit karat putih. PGPR galur Bacillus firmus J8 paling efektif menekan karat putih, sedangkan galur Lysinibacillus fusiformis C71 paling efektif meningkatkan pertumbuhan tanaman krisan. Kelima galur rizobakteri dan formulasi komersial meningkatkan diameter bunga.

Abstract

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.

Abstract

Resistance of Six Lines from Farmers against Bacterial Leaf Blight (Xanthomonas oryzae pv. oryzae) Bacterial leaf blight (BLB) caused by Xanthomonas oryzae pv. oryzae is a disease that detrimental to rice production in Indonesia. One effort to control the disease is to use BLB resistant varieties. This study aims to evaluate the development of bacterial leaf blight on six lines (TCIPB202101, TCIPB202102, TCIPB202103, TCIPB202104, TCIPB202105, and TCIPB202106) and two control varieties (Ciherang and Inpari 30). Green house experiment was conducted in Cikabayan Dramaga using artificial inoculation. The study was conducted by observing the incubation period, lesion length and disease intensity at 7 and 14 days after inoculation (DAI). The results showed that all the lines tested were resistant to BLB and had better resistance compared to the control varieties. The TCIPB202105 and TCIPB202106 lines had the best resistance response with an average disease intensity below 1%. Meanwhile, the TCIPB202101 and TCIPB202102 lines had the highest percentage of disease intensity although they are still considered as moderately resistant category.

Abstract

Plant growth-promoting rhizobacteria (PGPR) is a promising technology for controlling viral diseases, including pepper yellow leaf curl disease (PYLCD) of chili pepper caused by Begomovirus infection. The objectives of this research were to investigate the effectiveness of PGPR containing Pseudomonas fluorescens PF1 and Bacillus polymyxa BG25, as well as their combination with other protective agents, to control PYLCD under field conditions in an endemic region. The treatments consisted of a single application of PGPR (a mixture of P. fluorescens PF1 and B. polymyxa BG25), guano tea, endophytic fungus H5, and neem oil; combination of PGPR with guano tea, endophytic fungus H5, and neem oil; conventional pesticide that relies on synthetic chemical insecticide sprayed weekly; and untreated plots. The experiment was arranged in a randomized block design with four replications. Treatment with PGPR alone was able to delay disease onset by 2.25 weeks, but it caused only a slight reduction in disease incidence. The combination of PGPR + guano tea and PGPR + endophyte H5 provided the best results in controlling PYLCD. The combination of PGPR + guano tea and PGPR + endophyte H5 delayed disease onset by 2.75 weeks and 3.25 weeks, respectively, and reduced disease incidence with effectiveness rates of 52.72% and 52.08%, respectively. These two treatment combinations gave the best performance for plant growth and yield.
