“…Significant differences between different treatments were not observed for shoot P uptake but were higher in all the treatments in comparison with control plants. The present study is in accordance with the other findings that application of consortium of AM fungi, Pseudomonas resulted in increased phosphorus and nitrogen content (Akhtar & Siddique 2008b). Prominent increase in the root N content in consortium of all the bioinoculants indicates that AM fungi might have played little role in the solubilisation of soil minerals, especially phosphorus and nitrogen.…”

Tanwar Most of the vegetable crops are known to depend upon arbuscular mycorrhizal fungal (AM) symbiosis for growth and development, since AM fungi provide nutrients and water in exchange for photosynthates. The influences of AM fungi (glomus intraradices (G) and Acaulospora laevis (A)) with Trichoderma viride (T) and Pseudomonas fluorescens (P) alone and in combinations on growth, mycorrhization, chlorophyll content, nutrient uptakes, and yield of broccoli plants were studied in pot culture under glasshouse conditions. The obtained results demonstrated that the single inoculation of broccoli plants with T. viride significantly increased the above ground fresh weight, root length, chlorophyll b, head diameter, root phosphorus, and shoot nitrogen in comparison to uninoculated control plants. On the other hand, consortium of G+A+T+P significantly increased plant height, above ground dry weight, root fresh weight, chlorophyll a, head fresh weight, and root nitrogen content. Similarly, G+T showed maximum leaf area, and P alone showed maximum uptake of shoot phosphorus. Whereas when P was supplied along with T, early flowering was recorded. AM fungal colonisation was negligible and only root tips were found infected in G or A treated plants which confirms low dependency of broccoli on AM fungi.

“…In addition, the intensity of the chickpea root-rot disease complex was reduced after the combined application of Glomus intraradices with either Pseudomonas straita or Rhizobium than when they were applied separately (Akhtar and Siddiqui 2008a). Similarly, the greatest reduction in the chickpea root-rot disease complex was observed when Pseudomonas alcaligenes, Bacillus pumilus and Glomus intraradices were used together (Akhtar and Siddiqui 2008b). Application of Paecilomyces lilacinus with composted cow manure on tomato also gave better control of M. incognita than either did individually (Siddiqui and Akhtar 2008).…”

“…PGPR were grown in nutrient broth medium for 72 h at 37°C before their use as biocontrol agents; hence, no significant nutrients remained in the medium (Siddiqui and Akhtar 2008). Similarly, the AM fungal inoculum included a few Rhodes grass segments and some soil particles, but these additions did not significantly affect plant growth (Akhtar and Siddiqui 2008b).…”

Antagonistic fungi (Aspergillus niger CA and Penicillium chrysogenum CA1), plant growth-promoting rhizobacteria (PGPR) (Burkholderia cepacia 4684 and Bacillus subtilis 7612) and AM fungi (Glomus intraradices KA and Gigaspora margarita AA) were assessed alone and in combination for their effects on the growth of tomato and on the reproduction of Meloidogyne incognita in glasshouse experiments. Application of antagonistic fungus, PGPR, or AM fungus alone or in combination significantly increased the length and shoot dry mass of plants both with and without nematodes. The increase in shoot dry mass caused by Gl. intraradices KA in plants without nematodes was greater than that caused by PGPR or antagonistic fungi. Similarly, the increase in shoot dry mass caused by Bu. cepacia 4684 in plants with nematodes was greater than that caused by P. chrysogenum CA1. Application of Bu. cepacia 4684 caused a 36.1% increase in shoot dry mass of nematode-inoculated plants followed by Ba. subtilis 7612 (32.4%), A. niger CA (31.7%), Gl. intraradices KA (30.9%), Gi. margarita AA (29.9%) and P. chrysogenum CA1 (28.8%). Use of Bu. cepacia 4684 with A. niger CA caused a highest (65.7%) increase in shoot dry mass in nematode-inoculated plants followed by Ba. subtilis 7612 plus A. niger CA (60.9%). Burkholderia cepacia 4684 greatly reduced (39%) galling and nematode multiplication, and the reduction was even greater (73%) when applied with A. niger CA. Antagonistic fungi had no significant effect on root colonization caused by AM fungi. Applying Bu. cepacia 4684 with A. niger CA may be useful in the biocontrol of M. incognita on tomato.

“…According to Moghaddam et al (2014), B. pumilus ToIrFT-KC806241 and ToIrMA-KC806242 showed potential antagonism against M. javanica by reducing the number of galls and eggs in tomato plants. Similarly, B. pumilus reduced the gall formation and reproduction of the root-knot nematode (Akhtar and Siddiqui, 2008). Several studies have reported the nematicidal effect of B. pumilus on root-knot nematodes in different agricultural crops (Pinho et al, 2009;Mekete et al, 2009: Oliveira et al, 2007.…”

The present study described the isolation of 2-methylbutyric acid (2-MBA) produced from Bacillus pumilus L1, to subsequently investigate its nematicidal activity for the control of the root-knot nematode. The results showed that 2-MBA could be purified by chromatographic techniques and was identified using nuclear magnetic resonance and liquid chromatography-mass spectrometry. Crude extract and partially purified compounds had a significant effect on the inhibition of egg hatchability and second-stage juvenile (J2) mortality. A dose-dependent effect of 2-MBA was observed for J2 mortality and egg hatchability. Egg hatchability was 69.2%, 59.9%, 32.7%, and 0.0% at 125, 250, 500, and 1000 μg mL -1 of 2-MBA after 4 d of incubation, respectively. Meanwhile, J2 mortality was in the range of 24.4%-100.0% after 2 d of incubation, depending on the concentrations of 2-MBA used. A pot experiment also demonstrated that treatment of B. pumilus L1 culture caused a significant reduction in the number of galls, egg masses, and J2 population than that of the tap water (TW) control. However, as the B. pumilus L1 culture concentration was decreased, the efficacy of nematode control by treatment of B. pumilus L1 culture was reduced compared to that of TW. B. pumilus L1 inoculation at different concentrations also promoted cucumber plant growth. Therefore, our study demonstrated the potential of 2-MBA from B. pumilus L1 as a biocontrol agent against the root-knot nematode and a plant growth promoter for cucumber plants.
