“…Maintaining to produce a single flower in a plant had made the character was predictably less affected by rust infection when the infection was still in leaves part. In severe incidences, the pustule symptoms might reach the flower petal and made the flowers unsalable as reported by Hanudin, Budiarto, & Marwoto (2017).…”

“…All the bio-and synthetic fungicides treated plants had more than 10 days of shelf life, while the negative control had less than 9 days. The low rust infection represented means the healthier photosynthetic organs is to support the plant growth and development including the flower development (Hanudin, Budiarto, & Marwoto, 2017). The optimum flower development process revealed premium flower quality including longer shelf life.…”

“…Perbaikan kualitas bunga ini mengindikasikan peningkatan kualitas pertumbuhan sebagai akibat rendahnya serangan karat selama masa produksi tanaman. Rendahnya serangan karat ini diduga berhubungan dengan persitensi mikrob antagonis yang lebih lama dalam menekan perkembangan penyakit karat dibandingkan dengan kultur teknis petani yang berbasis fungisida sintetik, terutama saat memasuki fase reproduktif (Hanudin, Budiarto & Marwoto 2017).…”

Pengendalian penyakit karat putih pada tanaman krisan dengan menggunakan agens hayati merupakan salah satu upaya penting dalam mewujudkan sistem pertanian yang berkelanjutan dan ramah lingkungan. Penelitian bertujuan mengevaluasi kemangkusan biofungisida berbahan aktif Cladosporium sp. pada beberapa formulasi (WP-1, WP-2, dan WP-3) dibandingkan dengan penggunaan fungisida sintetik dan asam salisilat dalam mengendalikan penyakit karat pada krisan cv. Puspita Nusantara. Penelitian berlangsung selama 1 tahun dari bulan Januari hingga Desember 2016, dilakukan melalui dua tahap, yaitu penelitian super impose di Kebun Percobaan Balai Penelitian Tanaman Hias dengan menggunakan rancangan acak lengkap terdiri atas enam perlakuan (WP-1, WP-2, WP-3, AS, FS, dan kontrol) dengan lima ulangan, setiap ulangan terdiri atas 100 tanaman. Aplikasi dilakukan setiap minggu pada sore hari dan verifikasi kemangkusan di lahan petani menggunakan uji t berpasangan terdiri atas dua perlakuan (WP-1 2 g/l dan fungisida sintetik berbahan aktif pyraclostrobin 250 g/l) dengan 10 ulangan. Hasil evaluasi kemangkusan perlakuan biofungisida menunjukkan bahwa seluruh formulasi mampu menekan serangan penyakit karat sebesar 17% hingga 27%. Demikian juga dengan hasil uji di lahan petani formulasi WP-1 mampu mengimbangi fungisida sintetik dengan menyisakan serangan karat 1,6% dan 1,7%. Hasil percobaan menunjukkan bahwa seluruh formulasi biofungisida mempunyai keefektifan yang sama dalam menurunkan intensitas dan perkembangan penyakit karat, dengan fungisida sintetik berbahan aktif pyraclostrobin 250 g/l dengan kualitas bunga yang cenderung lebih baik dibandingkan dengan kultur teknis petani yang berbasis fungisida sintetik.KeywordsDendranthema grandiflora; Agens hayati; Intensitas serangan; Evaluasi lapanganAbstract The application of biological agents to control white rust on chrysanthemum is one important issues in the era of ecofriendly and sustainable agriculture, including in chrysanthemum production system. The research was carried out to evaluate the application of several biofungicide formulations with the active ingredient of Cladosporium sp., i.e. WP-1, WP-2, and WP-3, synthetic fungicide and salicylic acid for white rust control in chrysanthemum cv. Puspita Nusantara. The research was conducted from January to December 2015, through two subsequent experiments, i.e. super-impose experiment that located in Indonesian Ornamental Crops Research Institution using a complete randomized design consisting of six treatments (WP-1, WP-2, WP-3, AS, FS, and control) and five replications and verification of biofungicide effectivess at the growers’ nursery using paired t test consisting of dua treatments (WP-1 2 g/l) dan synthetic fungicide with active ingridient pyraclostrobin 250 g/l) and 10 replications. The results of evaluation of biofungicide treatment efficacy showed that all of formulations biofungicide formulation were able to suppress rust attack by 17% to 27%. Likewise with the results of tests on farmer land the WP-1 formulation was able to compensate for synthetic fungicide with 1.6% and 1.7% rust attack. The results of this experiment showed that all of biofungicide formulations and synthetic fungicides had the same effectiveness in reducing the intensity and development of rust disease and improved flower quality compared to farmers’ technical culture based on synthetic fungicides.

“…The rhizobacteria-chrysanthemum interaction can have effect on the plant growth and also in the biological control of some pathogens. A mixture of rhizobacteria such as Pseudomonas, Bacillus, Azotobacter, inoculated on chrysanthemum reduce the white rust incidence (Hanudin et al, 2017) and the combined inoculation of fungi Glomus mosseae and the rhizobacteria Pseudomonas putida can mitigate phytoplasma damage (D'Amelio et al, 2011). Although, these researches present promissory use of rhizobacteria Pseudomonas as inoculant, there are no studies on the effect of Pseudomonas strains on chrysanthemum seedlings and on plants cultivated in the field conditions, as well as soil quality indicators such as microbial biomass and basal respiration, especially in tropical soil in Brazil.…”

Chrysanthemum production stands out in ornamental plants market and several techniques can improve the production of this plant. Among them, is the use of beneficial microorganisms such as plant growth promoting rhizobacteria (PGPR); however, the use of PGPR has not been explored enough so far in chrysanthemum production, especially in field conditions. With regards to rhizobacteria, the group, Pseudomonas, can be explored as a good alternative to improve plant development. Hence, the objective of the present study was to evaluate the effect of PGPR on seedlings and, on the field experiments, plants development and the impact on rhizosphere soil. The strains of Pseudomonas putida IAC-RBcr5 and IAC-RBcr2 were able to improve chrysanthemum shoot biomass up to 40%. In addition, the plants treated with these strains had increased number of flowers, which is a desirable feature for the flower market. This is the first study to demonstrate the effect of P. putida strains on chrysanthemum seedlings and cut flowers grown in tropical field conditions.
