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.

Two isolates of bacterial endophyte from soybean root were found to be effective to control bacterial pustule caused by Xanthomonas axonopodis pv. glycines. Formulation of the bacterial isolates is required to maintain the effectivity of this bacterial isolates during storage, transportation and application. The aim of this research was to obtain the best carrier for formulation to maintain the effectivity of bacterial endophyte in storage to control bacterial pustule on soybean. Three kind of carrier agent was evaluated for formulation of bacterial endophyte i.e. peat soil, tapioca flour and coconut water + 1% palm oil. Each carrier agent was combined with 5 treatment of storage time i.e. 0, 1, 3, 5 and 7 weeks. Soybean plants was inoculated by. X. axonopodis pv. glycines 2 weeks after planting by rubbing bacterial suspension (106 cel mL-1) on lower surface of leaves. The results showed that all formulas of bacterial endophyte were able to suppress the bacterial pustule on soybean. The best formulations were bacterial endophyte in peat soil stored for 1 and 7 weeks (effectivity rate 79.85% and 77.02%) and coconut water + palm oil and storaged for 3 weeks (effectivity rate 77.46%).

Yellow leaf curl disease of pepper has become an emerging important disease in West Sumatra since early 2000. Several attempts have been made, including disease survey and detection, in order to identify the causal agent of the disease. Pepper (Capsicum annuum) plants showing yellow leaf curl from West Sumatra were analyzed for presence of Begomovirus employing Polymerase Chain Reaction (PCR) with degenerate primers pAL1v 1978 and pARc 715. A DNA fragment of 1.6 kb was successfully amplified and subjected to direct sequencing. A stem loop region was found in the nucleotide sequence obtained, which contains the conserved nucleotide signature sequence TAATATTAC present in begomoviruses. Based on the stem loop region comparisons and phylogenetic analysis, the virus isolates from West Sumatra showed the closest relationship to Pepper yellow leaf curl Indonesia virus (PYLVIV) and Tomato yellow leaf curl Indonesia virus (TYLCIV). The sequence was different from other Asia Begomoviruses reported earlier. These isolates were divided into three groups which were tentatively called Pepper yellow leaf curl Indonesia virus-West Sumatra-[group 1], -[group 2] and -[group 3] {PYLCIV-WS-[group1], -[group2], and -[group3]}.

Banana blood disease (Blood Disease Bacteria, BDB) caused by Ralstonia solanacearum Phylotype IV is the most important banana disease in Indonesia. So far, information on the spread of disease by insects is very limited. The research was aimed to determine the role of insect as a disseminator of R. solanacearum Phylotype IV and to determine the amount of BDB inoculum carried by each individual insect. The experiment was conducted in May - September 2008. Samples of insects (adult insects, the young insects, larvae, eggs), nectar, and pollen were taken from a colony of Trigona spp. collected from BDB endemic area, Baso plateau (876 m asl) using purposive sampling method. Active adult insects were collected from the BDB infected banana flowers and healthy banana flowers. BDB on adult insects was isolated from the caput and abdomen, while for the young insects, larvae and pupae the isolation source were not differentiated. Each of the samples was rinsed, macerated, and cultured on medium containing Triphenyl Tetrazolium Chloride (TTC). BDB isolate characterization and identification were conducted through morphological, physiological, and pathogenicity tests. The parameter observed was the: population of BDB (cfu/ml) on each stage of insect development. The results showed that BDB can be isolated from the outside and the inside of the body of an adult, a young insect, pupa, larva also on pollen and nectar but it was not found in eggs. BDB population was higher in inside part fo the insect body in each phase of the development of the insect. From all phases, the BDB was higher in inner part of the body of adult insects which have visited infected banana flower.

The Baramban Farmers Group, since 2014, has been carrying out healthy vegetable farming with vegetable products that have been certified Prima 3. However, until now, the management of healthy vegetable farming by the Baramban Farmers Group in Banuhampu District, Agam Regency has not experienced much development in farming because it has not created a broad market with prices that favor the welfare of farmers. Strengthening farmer institutions in marketing healthy vegetables is thus very important and have become an essential element in developing healthy vegetable agribusiness in local, national, and even global markets. The method used is counseling, coaching and mentoring. This service activity is planned to be carried out over the next five years, starting with building a cooperation agreement with the Baramban farmer group starting in 2020. Several alternative solutions to solve the problems of healthy vegetable farmer group partners proposed and agreed upon by the Baramban Farmer Group are: a. Carry out mentoring activities for healthy vegetable farmers by transferring resources from universities through integrated science an agribusiness perspective, b, empowering farmers based on group institutional strengthening to build collective action that is independent of farmers to drive healthy vegetable markets, c. Facilitate farmers to create healthy vegetable market segments through modern markets and online markets with information technology 4.0 and 4. Building partnerships with Transmart as a modern market on a national scale and has a global-scale marketing network. The conclusion is that farmer groups are willing to become partners of the Community Service Team in a community partnership program scheme to help businesses develop.
