“…Bacillus velezensis GF267 reduced the intensity of tomato bacterial spots and increased the chlorophyll content in plants as reported by Mates et al (2019). Various strains of Pseudomonas fluorescens have also been shown to be effective biocontrol agents against multiple plant diseases (Yendyo et al, 2017;Kulimushi et al, 2021;Mosahaneh et al, 2021). As observed in the current study, the combination of these two isolates was more effective in controlling wilt as compared to the treatments containing these isolates alone.…”

Fusarium oxysporum is one of the most damaging plant pathogens causing Fusarium wilt in many plants leading to serious economic loss. The fungus colonizes the xylem, which leads to resistance in water flow in the plant thereby affecting the rate of photosynthesis. The present study focuses on the selection of bacterial endophytes isolated from tomato plants and evaluating their potential to antagonize Fusarium oxysporum in tomato in vivo. The results obtained indicated that two endophytic isolates, namely Pseudomonas fluorescens BUMD5 and Bacillus velezensis BUMD9, could act as efficient biocontrol agents (BCAs) as they inhibited the growth of pathogen by 67.2 and 69.1%, respectively, in vitro. Both the isolates were found to produce hydrolytic enzymes chitinase and protease. They also produced siderophore and hydrogen cyanide (HCN). The consortia of both the isolates significantly reduced the infection percentage by about 67% and a 3-fold decrease in disease severity was observed as compared to pathogen control. The treatment of infected plants with these potent isolates was also beneficial in improving the overall photosynthetic performance index (PI). Thus, plants treated with consortia of these isolates exhibited better overall plant growth despite being infected by the pathogen.

“…It is necessary to discover cheap, applicable, effective, and efficient solutions to overcome this problem. An effort that can be done is to develop a bionematicide formula with the active materials of antagonistic bacteria (Viljoen et al 2019;Mosahaneh et al 2021). In previous study, we found 8 bacterial isolates including 6 endophytic bacteria and 2 rhizobacteria.…”

Abstract. Asyiah IN, Prihatin J, Hastuti AD, Winarso S, Widjayanthi L, Nugroho D, Firmansyah K, Pradana AP. 2021. Cost-effective bacteria-based bionematicide formula to control root-knot nematode Meloidogyne spp. in tomato plants. Biodiversitas 22: 3256-3264. The root-knot nematode, Meloidogyne spp. can infect and cause loss production in various horticultural plants, including tomatoes. In the previous study, we found 3 endophytic bacteria isolates and 1 rhizobacterium isolate that could control several plant-parasitic nematodes. In this study, we formulated these bionematicide isolates with cheap and environmentally friendly organic materials. The formula was fortified using several organic matters, vitamin sources, protein sources, and sugar sources. The research was conducted in an experimental land with a history of severe root-knot nematode infection. The analysis showed that there were 63.7 J2 Meloidogyne spp. per 100 ml of soil on the experimental land. The application was given at a time interval of 2 weeks at the concentration of 0.5%, 1%, 1.5%, and 2%, with a dose of 100 ml per plant. As a negative control, the plant did not give any treatments, and as a positive control, the plant was given 5 g carbofuran per plant. The results revealed that treatment with 2% bionematicide formula concentration showed the best consistent result. This treatment increased canopy wet weight by 38.63% and root dry weight by 106.97% compared to negative control. The P4 treatment was also found effective to increase fruit weight by 33.61% and fruit diameter by 26.16% as compared to negative control. Increased plant growth in P4 treatment was closely related to the total of root-knot suppression and root damage intensity. In the P4 treatment, the total of root-knots and root damage intensities was 44.83% and 32.66%, respectively, compared to the negative control. This suppression also occurred in the nematode population and nematode eggs. In the P4 treatment, the total of Meloidogyne spp. J2 in soil and root was lower by 60.74% and 66.24%, respectively, compared to the negative control. A similar phenomenon also occurred in the total of eggs, which was 79.40% lower than the total of eggs in the negative control. This study provides the latest information about a cost-effective bacteria-based bionematicide formula, which is effective in suppressing Meloidogyne spp. infection in tomato, and promotes the growth and development tomato plant.

The aim of this research was to get protein-fractions from the aqueous extract of P. sanguineus through gel filtration chromatography (GFC) to induce resistance to Meloidogyne spp. in Micro-Tom tomato plants. Precipitation of protein from the aqueous extract (AE) of basidiocarps was performed based on increasing ethanol gradients 20%, 40%, 60%, 80% and 95%, which were individually centrifuged. Each ethanol-protein precipitate (EPP) was fractionated by using GFC, and isolated proteins (IP) were identified based on molecular mass. Each EPP and IP were tested in vitro for nematicide and nematostatic activity against M. incognita and M. javanica, through motility and mortality evaluation. Regarding resistance induction assays, root samples were also collected for the analysis of defense enzymes peroxidase (POX), polyphenoloxidase (POL) and phenylalanine ammonia-lyase (FAL). Six IP (named as I, II, III, IV, V and VI) were obtained through GFC, which molecular weights were 4.81, 47.98, 0.17, 25.78, 4.25 and 4 KDa, respectively. P. sanguineus basidiocarps contain proteins with no nematicide/nematostatic effects but capable of reducing M. javanica infection in Micro-Tom tomato plants, which can occur by resistance induction involving peroxidase activity.
