<p>Bacterial leaf blight caused by Pseudomonas cichorii is a major disease in chrysanthemum plants almost all over the world. In Indonesia, this pathogen can cause damage to chrysanthemum 10- 60%. Bacteria spread from one plant to another through water droplets from modern irrigation networks as well as conventional irrigation. P. cichorii is a polyphagic pathogen, which infects succulents and others across continents with varying incidence. Symptoms of transmission of this pathogen in each type of plant are always different, and effective control methods have not been found. This article discusses the virulence of pathogens, the incidence of transmission, and recommendations for controlling bacterial leaf blight on chrysanthemums in Indonesia. A search of various references from within and outside the country shows that P. cichorii can be controlled by combining several methods, namely (a) the use of tolerant varieties (Puspita Nusantara, Puspa Kania, Dwina Kencana, Dwina Pelangi, Pasopati, Paras Ratu, and Wastu Kania), (b) technical culture (extracting infected leaves and watering in the morning), and (c) application of synthetic chemical bactericides with active ingredients of hydrogen peroxide and peroxyacetic acid, or biopesticides with active bacterial isolates of the antagonistic bacteria Bacillus subtilis MI600, and B. amyloliquefaciens IN937, and combination of P. fluorescens Pf Irana with Pf Slada-2.</p><p>Keywords: Chrysanthemum, P. chicorii, bacterial leaf blight disease, epidemiology, control</p><p> </p><p><strong>Abstrak</strong></p><p><strong>PENYAKIT HAWAR DAUN BAKTERI (Pseudomonas cichorii (Swingle 1925) (STAPP 1928) PADA TANAMAN KRISAN (Dendranthema grandiflora Tzvelev) DAN UPAYA PENGENDALIANNYA DI INDONESIA</strong></p><p>Hawar daun bakteri yang disebabkan oleh Pseudomonas cichorii merupakan penyakit utama pada tanaman krisan hampir di seluruh penjuru dunia.

The bacterial leaf blight (BLB) caused by Xanthomonas oryzae pv. oryzae (Xoo) is one of the most serious rice diseases, causing huge yield losses worldwide. Several technologies and approaches have been opted to reduce the damage; however, these have had limited success. Recently, scientists have been focusing their efforts on developing efficient and environmentally friendly nanobactericides for controlling bacterial diseases in rice fields. In the present study, a scanning electron microscope (SEM), transmission electron microscope (TEM), and a confocal laser scanning microscope (CLSM) were utilized to investigate the mode of actions of ginger EOs on the cell structure of Xoo. The ginger EOs caused the cells to grow abnormally, resulting in an irregular form with hollow layers, whereas the dimethylsulfoxide (DMSO) treatment showed a typical rod shape for the Xoo cell. Ginger EOs restricted the growth and production of biofilms by reducing the number of biofilms generated as indicated by CLSM. Due to the instability, poor solubility, and durability of ginger EOs, a nanoemulsions approach was used, and a glasshouse trial was performed to assess their efficacy on BLB disease control. The in vitro antibacterial activity of the developed nanobactericides was promising at different concentration (50–125 µL/mL) tested. The efficacy was concentration-dependent. There was significant antibacterial activity recorded at higher concentrations. A glasshouse trial revealed that developed nanobactericides managed to suppress BLB disease severity effectively. Treatment at a concentration of 125 μL/mL was the best based on the suppression of disease severity index, AUDPC value, disease reduction (DR), and protection index (PI). Furthermore, findings on plant growth, physiological features, and yield parameters were significantly enhanced compared to the positive control treatment. In conclusion, the results indicated that ginger essential oils loaded-nanoemulsions are a promising alternative to synthetic antibiotics in suppressing Xoo growth, regulating the BLB disease, and enhancing rice yield under a glasshouse trial.
