Pantoea stewartii subsp. stewartii is the pathogen causing stewart’s wilt disease in maize. The occurrence of the disease was recently reported in Indonesia with limited information. Research was conducted to characterize several isolates of P. stewartii subsp. stewartii isolated from maize plants collected from 6 districts in West Sumatra. Leaves showing yellow stripes symptoms along the vein was ground and suspeneded then the bacteria was isolated and incubated for 3 × 24 h at room temperature in nutrient glucose agar (NGA). Pure bacterial colonies gained from this medium was used for characterization. Assessment of bacterial characters was conducted based on morphological assay, physiological assay, biological assay (hypersensitivity, and pathogenicity) followed by polymerase chain reaction (PCR)-based identification. Unique characters of the family Enterobacteriaceae was observed on 7 isolates based on morphological and physiological characters, and only 4 isolates (PR1, PP, ST1, LA) gave positive reaction on hypersensitivity and pathogenicity test. Further molecular identification confirmed 3 out of 7 isolates had high homology to Pantoea stewartii, i.e. Pantoea stewartii strain R1-104, R1-132, and ATCC 29923 for isolates LA, PR1, and PR2, respectively.

The community service carried out by the Ekasakti Padang University Team is in the Nagari Tuik area, Batang Kapas District. the northern part of the South Coast District. The community, in general, is farming, because the agricultural land is very large, namely 256 ha. There are still many people who cultivate rice fields, but not many have cultivated corn which further increases income. Because the base price of corn is more stable than the base price of grain. The base price of flat corn alone is between Rp. 2500 – Rp. 5000 a kilo. In addition, corn can be processed into various products such as steamed brownies made from corn and sweet corn pudding. This service socializes the cultivation of sweet corn plants and their processing so that they can increase people's income and increase knowledge about corn cultivation. Knowledge increased from 24.6% to 80.6%. And people's income also increased with the production of steamed brownies with a selling price per unit of Rp. 2,500. BEP will be achieved only when 123 pieces are produced. So if it is produced more than that, it has already benefited. With this sweet corn cultivation program, it can be a community empowerment program
