“…Meanwhile, the introduction of hot water at 55 °C for 25 minutes on tomato seeds infected by Clavibacter michiganensis. michiganensis (Smith) lead to a low germination rate of 52.22% (Nalis, 2015). This also occured after introducing corn seeds infected by Pantoea stewartii subsp.…”

Burkholderia glumae is a seed-borne pathogen of rice known to cause bacterial panicle blight disease. The lack of effective control methods makes seed treatment the alternative management approach. The aim of this research was to determine an effective seed treatments technique, using liquid smoke, clove oil, hot water and copper hydroxide fungicide treatment against bacteria B. glumae. The experiment used a complete randomized design with five treatments and three replications, including control, liquid smoke, clove oil, hot water, and copper hydroxide fungicide. The results showed the propensity for all treatments to reduce bacterial populations on rice seeds, while liquid smoke, clove oil, and fungicide did not reduce vigour and viability. Application of copper hydroxide fungicide 77% at concentration of 5% was recommended as the best treatment to control the bacterial pathogen. Keywords: Burkholderia glumae, clove oil, copper hydroxide fungicide, hot water, liquid smoke, rice

“…Metode perlakuan benih yang sesuai diperlukan agar tanaman terbebas dari patogen tular benih dan tidak menurunkan kualitas benih. Hasil penelitian Nalis et al (2015) menunjukkan perendaman benih terinfeksi dengan bakterisida dengan konsentrasi 100 ppm sebelum dan setelah perlakuan panas kering pada suhu 45, 50, dan 55°C selama 24 jam cukup efektif menekan bakteri P. stewartii subsp. stewartii pada benih.…”

Maize is one of the most important worldwide agricultural crops that their seed is considered a valuable international trading item. The seeds are mainly originated from United States, where the world most intensive development of new varieties occurs. Pantoea stewartii is a pathogenic bacteria of maize that occurs primarily in the US. Stewart wilt disease in maize caused by the bacterium Pantoea stewartii is become a new disease of maize in Indonesia. The stewart wilt disease was first reported in West Sumatra with the disease incidence of 1−15%. This paper discusses the epidemiology and control efforts of the bacterial stewart wilt disease in maize. Stewart wilt disease is a seed borne disease and it can transmitted by insect vector Chaetocnema pulicaria. P. stewartii has a wide host range including maize plant. In addition to maize plants, the pathogen also attacks sugarcane, sorghum, wheat, green beans, cucumbers, and several types of grasses. The abundant availability and wide range of its hosts, allows the pathogen to easily find the host to survive and develop. P. stewartii attacks maize in all stages of plant growth. The emergence of this disease on maize plant is mainly due to imported seeds from outside of Indonesia. Seed is the most suitable carrier media for pathogens to spread across its natural boundaries. One of the efforts to prevent the outbreak of the disease in Indonesia is to control its insect vectors. Several efforts that can be done to control the disease are environmental sanitation and by chemical pesticides with active ingredient such as imidacloprid, thiamethoxam, and clothianidin.Keywords: Maize, Pantoea stewartii, host plant, seed treatment AbstrakJagung merupakan salah satu komoditas pangan dan pakan penting dunia dan benihnya diperdagangkan secara internasional. Volume tertinggi perdagangan benih jagung berasal dari Amerika Serikat yang merupakan negara penghasil utama varietas unggul baru jagung di dunia. Pantoea stewartii adalah bakteri patogenik penting pada tanaman jagung, khususnya di Amerika Serikat. Penyakit layu stewart pada tanaman jagung disebabkan oleh bakteri Pantoea stewartii yang merupakan penyakit baru di Indonesia. Penyakit ini pertama kali dilaporkan di Sumatera Barat dengan insidensi 1−15%. Makalah ini membahas epidemiologi dan upaya pengendalian penyakit layu bakteri stewart pada tanaman jagung. Penyakit layu stewart merupakan penyakit tular benih dan tular serangga melalui vektor Chaetocnema pulicaria. P. stewartii memiliki inang yang luas, termasuk tebu, sorgum, gandum, kacang hijau, mentimun, dan beberapa jenis rumput-rumputan. Melimpahnya ketersediaan inang menjadikan patogen ini mudah dan cepat berkembang. Penyakit layu bakteri stewart pada tanaman jagung dapat berasal dari benih impor. Benih merupakan media pembawa penyakit yang paling efektif dan menyebar luas dengan melintasi batas alaminya. Salah satu upaya untuk mencegah wabah penyakit layu stewart ialah mengendalikan serangga vektor. Sanitasi lingkungan dan penggunaan pestisida berbahan aktif imidacloprid, thiamethoxam, dan clothianidin merupakan alternatif pengendalian.Kata kunci: Jagung, Pantoea stewartii, tanaman inang, perlakuan benih
