After use, the dominant bacterial flora in the soil steadily maintains its dominant position. Fiji 2014). Svalbard and Jan Mayen It has a good effect of degrading organic phosphorus in soil. Chitinase plays an important role in hydrolyzing chitin, the structure component in egg shell, and thus reducing nematode multiplication. Maldives statement and Paraguay Jersey Ghana Falkland Islands A micro-plot field experiment was carried out in a loamy soil (a mixture of coarse sand (2.9%), fine sand (20.7%), silt (39.8%), and clay (36.6%)) located at the Experimental Agronomy Farm, Faculty of Agriculture, Mansoura University, Egypt, to assess the nematicidal properties and induction resistance of certain bio-agents to sugar beet plant var.

Bouvet Island Haiti In vitro propagation was carried out in biotechnology laboratory at Nematological Research Unit (NERU), Agricultural Zoology Department, Faculty of Agriculture, Mansoura University, Egypt, to produce sterilized multiple shoots, the main source of callus (Murashige and Skoog 1962). In agriculture, Bacillus megaterium can be used to produce phosphate-fixing and potassium-fixing fertilizers. Laos 2005). (2016) reported that the Bacillus species, B. megaterium, B. cereus, and B. subtilis, produced cytokinins. Austria Next to B. subtilis, B. megaterium has attracted the most attention in recent years. Additionally, the greatest suppression in nematodes’ population (95.7%), root galling (83.0%), and number of egg masses (100%) was also sustained at the soil amended with nemastrol + humisun + bio-arc + sweet basil callus + oxamyl since incorporation of such organic materials into soil might enhance B. megaterium activity that initiates antibiotics towards nematode population. Ukraine Google Scholar, Murashige T, Skoog F (1962) A revised medium for rapid growth and bio assays with tobacco tissue cultures. Ecuador Improve the soil, restore ecological balance, and improve the quality of agricultural products. It is a common strain used in biological organic fertilizers. Bacillus megaterium malachite-green staining Bacillus megaterium. Previous studies reported that application of bio-arc + nemastrol under greenhouse conditions increased the activities of related enzymes, i.e., PO and PPO, in roots of sugar beet infected with M. incognita, as they reached their peaks at day 9 from nematode inoculation (Ibrahim 2013; Mostafa et al. Herein, sweet basil callus (53.5%) and dried leaf powder (48.2%) exhibited the least reduction in nematodes’ population. Liechtenstein 2007). At the same time, it converts materials that are difficult to absorb in the soil into materials that are easily absorbed by crops, promotes the absorption and utilization of nutrients by crops, and improves the utilization rate of fertilizers. Bermuda 2006), but little attention has been given to their use in nematode management (Rocha et al. Azerbaijan The presence of rosmarinic acid and terpenoids in methanolic extract of dried callus and powdered leaves of sweet basil was evaluated, using thin-layer chromatography (TLC) and nuclear magnetic resonance (NMR) (Kintzios et al.

As fertilizer additive, use 1-2kg per ton fertilizer; 2. Malawi to assess the potential of bio-agents namely bio-arc ( Bacillus megaterium ), nemastrol (a mixture of active ingredients), humisun (humic acid), and dried sweet basil callus to suppress nematodes’ population and induce resistance in sugar beet.

PO and PPO are thought to reinforce cell walls (lignification and suberization) at the border of infection and further limit spread of pathogens (Passardi et al. RKN, Meloidogyne incognita (Kofoid & White) Chitwood, is among the most important nematode species in sugar beet fields (Korayem 2006) causing damage to the epidermis, cortex, and stele regions which leads to giant cells and galls formation on fibrous and lateral roots that affect water and nutrient absorption (El-Nagdi and Abd El Fattah 2011). Comoros Ivory Coast It has the ability to kill the insects which are harmful for the crops, forests or agriculture.

Saint Barthelemy The authors would like to thank to Dr. Hadeer Y. Darwish, Plant Res. The activities of both peroxidase (PO) and polyphenol oxidase (PPO) showed detectable fluctuations at the end of the experiment compared to untreated plants. Whilst growth parameters were significantly promoted (P ≤ 0.05) by the application of nemastrol and humisun in concomitant with bio-arc, sweet basil callus, and oxamyl (half recommended dose), such application induced significant (P ≤ 0.05) and maximum improvement in shoot (47.7%) and root (18.1%) lengths.

The integration of B. megaterium with the nemastrol, humisun, dried sweet basil, and oxamyl induced systemic resistance towards the challenger Meloidogyne spp. However, sugar beet plants showed healthy storage root with NS + HS + BA + DSBC +O and NS + HS + BA as well.

Argentina Utilization of biofertilizers based on the B. megaterium did not increase the number of Bacillus megaterium in the soil, but they were conducive to the stabilization of this strain in the soil environment that is crucial since any pressure affected on the homeostasis of soil environment has an adverse effect [ 50 ]. However, several plant species have been demonstrated to have nematicidal activity against plant parasitic nematodes (Salim et al. Saint Kitts and Nevis (308J2/250 g), Rotylenchulus reniformis (453 immature females/250 g), and other nematode genera, i.e., Tylenchorhynchus, Helicotylenchus, Aphelenchus, and Xiphinema.
