Indigenous rhizobacteria screening from tomato to control Ralstonia syzigii subsp. indonesiensis and promote plant growth rate and yield. Bacterial wilt is the most damaging vascular pathogen on tomato and many other crops in tropical, subtropical and warm temperate areas of the world which limits the production. Rhizobacteria have been concerned as potential biological control agents due to their ability to promote plant growth and health, and their role as antagonists of plant pathogens. The purpose of this research was to screen the best indigenous rhizobacteria (IRB) that able to control bacterial wilt disease and increase growth rate and yield of tomato plant. This research was conducted in 3 stages: (1) Isolation and selection of indigenous rhizobacteria as PGPR on tomato seedlings, consisted of 27 IRB isolates and a control, with triplications; (2) Selection of IRB isolates that control R. syzigii subsp. indonesiensis on tomato plants, which consisted of 8 treatments including 7 IRB and a control with 5 replications; (3) Characterization of IRB isolates ability to promote plant growth (indicated with IAA production & phosphate solubilizing). The variables observed were disease development, growth enhancement and IRB isolate ability to produce IAA and solubilize phosphate. The results showed that all IRB isolates were able to control bacterial wilt disease and increase the growth rate and yield of tomato. IR2.3.5, IR1.3.4 and IR1.4.2 were the best isolates in controlling R. syzigii subsp. indonesiensis and increasing the growth rate and yield by 81.25% and 68.72% respectively. All isolates showed various abilities to produce IAA, however, only isolates IR2.3.5 and IR1.3.4 that had abilities to solubilize phosphate.

Nagari Simabur is one of the nagari which is included in the Pariangan District, Tanah Datar Regency with the main sector only in the agricultural sector with the main crop being lowland rice. The problem that is often faced by Simabur farmers is the problem of pests and diseases which are the cause of the low growth and yield of the lowland rice plant. One of the main components of the IPM program that can be used as a biological control agent is the use of Trichoderma indigenous. In addition to the use of biological agents, the system or method of planting also affects the production results of the cultivated plants. The purpose of this community service is to increase public knowledge about the use of Trichoderma which can increase the growth and production of rice plants with the jajar legowo system. The method used in this activity is structured training and direct demonstration in the field. The results obtained from this activity were the production of grain weight/plant clump treated with Trichoderma was higher than the control with a difference of 42.45 grams. The conclusion of this activity is that the growth and yield of plants that were applied with Trichoderma were higher than those that were not treated with Trichoderma (control). The use of rhizobacteria is highly recommended because in addition to being easy to obtain, it also provides a positive value for plant growth and is good for environmental technology around cultivated plants.

Endophytic bacteria reside within plant hosts without causing disease symptoms. Bacterial endophytes promote plant growth and yield, suppress pathogens, may help to remove contaminants, solubilize phosphate, or contribute assimilable nitrogen to plants. The aim of this study were to obtain indigenous endophytic bacterial isolates, which have the ability to control bacterial pustule cause by Xanthomonas axonopodis pv. glycines and to increase growth and yield of soybean. The bacterial endophyte isolates were introduced as seed treatment (108 cfu/ml) and soil drench on 3 weeks old soybean seedling. Xanthomonas axonopodis pv. glycines were inoculated on one month old of soybean by pricking leaf methodes. The effect of bacterial endophyte on disease incidence, disease severity, plant growth and yield of soybean were evaluated. We have found two selected bacterial endophyte isolates from soybean’s rhizosphere (St4E1.1 and St1E1.1.), with the ability to control bacterial pustule and to increase growth and yield of soybean.Key words: bacterial endophyte, bacterial pustule, in planta technique, soybean

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%).
