The aim of study was to investigate the effect of two mycorrhizal fungus species Claroideoglomus etunicatum and Rhizophagus intraradices on the uptake of macronutrients and on the growth and yield of tomato hybrid plants cultivated in an ecological system. The experiment was carried out at an ecological farm in Grądy in the Lublin province of Poland, for three years (2015-2017). The experimental treatments included plants inoculated with Claroideoglomus etunicatum, Rhizophagus intraradices and plants without mycorrhizal inoculation used as a control. The mycorrhization of tomato roots with Claroideoglomus etunicatum and Rhizophagus intraradices resulted in an improved uptake of Ca and K through the plants. The length of the tomato roots, especially for the cultivars treated with Claroideoglomus etunicatum, were statistically longer than those of the control. Tomato roots inoculation with both of the studied mycorrhizal fungus strains significantly influenced the number of tomato leaves and improved the health status of the plant. The yield of tomato was not significantly affected by mycorrhization but Claroideoglomus etunicatum, to a greater extent than Rhizophagus intraradices reduced the yield of diseased fruit compared to the control. Among the studied mycorrhizal fungus species, better results were obtained with the application of Claroideoglomus etunicatum as compared with Rhizophagus intraradices for all examined features. Mycorrhizal inoculation contributed to the better growth of the plants, it improved their health and may be beneficially applied in the ecological production of tomatoes.

“…In conclusion, this study reveals that extrinsic as well as intrinsic variables can impact insect performance and behaviour in distinct ways. Arbuscular mycorrhizal fungi are discussed as potential biological pest control both below-and above-ground (Tscharntke et al, 2007;Tahat et al, 2010). Whenever environmental influences on pest insects are studied, we recommend investigating various insect life-history and behavioural traits at different time points of an individual's life span in order to gain a more complete picture of the consequences of microbe-modulated plant-herbivore interactions.…”

1. Life‐history traits of herbivores are shaped by the combination of various extrinsic and intrinsic variables. However, studies investigating the impact of both variables on insect behavioural phenotypes are rare, and research including the modulation of host plant quality by arbuscular mycorrhiza (AM) (extrinsic variable) and the herbivore developmental stage (intrinsic variable) on aphid behaviour is lacking. 2. To study the influences of extrinsic and intrinsic variables on aphid performance and behaviour, individuals of the generalist aphid pest Myzus persicae (Sulzer) were reared on Plantago lanceolata and Poa annua plants that were either non‐mycorrhized (NM) or mycorrhized (AM). Aphid performance was monitored over 2 weeks. Behavioural traits of nymphs were recorded twice during development after removing individuals from their feeding sites and placing them in an unknown environment (‘open field’), causing disturbance. Plant quality was determined by measuring the water content and leaf mass per area (LMA). 3. Differences in body mass of nymphs at day 6 dependent on plant species and treatment were compensated by the individuals within 4 days. Behavioural traits, considered as activity and exploration, were affected by the interaction between extrinsic and intrinsic variables (activity and exploration) and changed over ontogeny (activity). Independent of AM, a lower water content and LMA were recorded in P. annua leaves. 4. Overall, this study demonstrates that extrinsic and intrinsic variables need to be considered in combination and behavioural traits should be studied repeatedly during insect ontogeny to understand the complexity of microbe‐modulated plant–herbivore interactions.

“…AMF were used widely against various soil borne pathogens as biocontrol agents. Many workers have observed an antagonistic effect of AMF against some fungal pathogens (Tahat et al, 2010). Lakshmanan et al, (1987) in India reported a dramatic decrease in disease incidence by injecting rhizomes with carbendazim.…”

Soil solarization was applied for a field which was planted with infected banana seedlings. Spreading transparent plastic sheets of 80µ thickness was done from August, 1 until October 12, 2017 at the University Farm in Jordan Valley. Soil solarization was effective in elimination of all phytopathogenic propagules at 30 cm depth. Then clear plastic sheets were removed and the solarized land was planted with healthy banana seedlings cultivar Grand Naine. Banana plantlets were chemically treated as soil drench with Nanoparticle solution of 200 and 400 ppm of Silver Nanoparticles (AgNPs), two fungicides, Revanol and Tachigaren, Sodium Hypochlorite in addition of irrigation of one treatment with treated wastewater. Biological control included three treatments; Endomycorrhiza, Trichoderma as a commercial product (BioHealth) and plant growth promoting rhizo-bacteria. Fresh chicken and sheep manure was added to two treatments. Twelve treatments were distributed randomly in randomized complete block design. Endomycorrhizal inoculation with Glomus mosseae, 200 ppm of AgNPs, Revanol and Tachigaren treatments of banana seedlings were the most effective in completely protecting banana plants from Fusarium wilt during the whole experimental period. Several applications of Trichoderma, wastewater and 400 ppm of AgNPs were effective in maintaining some infected banana seedlings nine months after planting very healthy. Sheep and chicken manure treatments resulted with 60 and 40% disease incidence with Fusarium wilt respectively and 20% of disease incidence in Hypex, PGPR and control treatments. Wastewater, Nanoparticles 200 ppm and endomycorhizal treatments gave the highest ratio of sword sucker development. We recommend soil solarization and use of integrated program to control Panama disease of banana in Jordan.
