“…This association increases the supply of mineral nutrients to the plant, particularly those whose ionic forms have a poor mobility rate or those which are present in low concentration in the soil and thus promote plant growth (Ercolin & Reinhardt 2011). AM fungi also have the potential in plant disease control that has been demonstrated by various workers (Akhtar & Siddiqui 2008a;Kobra et al 2009;Singh et al 2010;Mwangi et al 2011). Several mechanisms are involved in disease control by AM fungi such as sink competition with infection sites, morphological changes in roots and root tissues, and changes in chemical constituents in plant tissue (Linderman 2000).…”

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.

“…For Trichoderma spp., isolated conditioning showed the best performance, followed by seed coating, being still superior to untreated seeds. Likewise, Mwangi et al (2011) emphasize that T. harzianum can be used to increase the growth of tomato seedlings. When evaluating seedling growth, it was observed that the suspension of B. subtilis bacterial cells provided lower results compared to the other techniques.…”

This study performs the microbiolization of black oat seeds with Trichoderma spp. and Bacillus subtilis by physiological conditioning, suspension of biological structures, and film coating, improving the control of pathogens and the effect on seed germination and vigor. Microbiolization with suspension of biological structures was carried out with commercial products based on Trichoderma spp. and Bacillus subtilis. Water restriction was performed in PDA + Mannitol (-0.8 MPa) medium, for Trichoderma spp. and B. subtilis. One hundred disinfected seeds of black oat were distributed in each plate. Once root protrusion occurred in one seed, the others were removed and dried, under laboratory conditions, for 48h. Film coating was performed with the addition of polymer to the treatment syrup containing Trichoderma spp. or B. subtilis. The seeds were dried for 48 h in a laboratory environment. A treatment was used to coat the conditioned seeds with the organisms, individually or in combination. Trichoderma spp. and B. subtilis control the pathogens associated with black oat seeds. B. subtilis increases the germination, seedling performance and growth, and dry matter accumulation of black oat. Trichoderma spp. promotes seedling shoot growth and dry matter accumulation in black oat plants. However, Trichoderma spp. and B. subtilis, applied by physiological conditioning and film coating, compromise the germination and emergence of black oat seedlings.

“…A comparison of mycorrhizal root colonization in the treatment AMF and treatment with both AMF and T. harzianum showed that they were not significantly different (Mwangi, et al (2011)), also they demonstrated that T. harzianum showed compatibility with AMF and no inhibitory effects on the development of mycorrhizal colonization was observed, also Sr'amek, et al 2000 found that T. harzianum did not affect colonization by AMF in three balcony plants (Verbena, Torenia, Diascia) inoculated with both AMF and T. harzianum. Data presented as the means of three replicates ± SD.…”

Pot experiments were conducted to study the effect of Arbuscular mycorrhizal fungi (AMF), Tricoderma harzianum and mix of them on suppression of fusarium wilt of three varieties of tomato (castle-rock, super marmande and peto 86). Disease severity, shoot and root Length, fresh, dry weights and the changes in amino acids, reducing sugars and phenolic compounds contents and phenylalanine ammonia lyase, ascorbate peroxidase, peroxidase and poly phenoloxidase activities were investigated. The treatments AMF, T. harzianum and AMF + T. harzianum gave significant reduction of disease severity and elevated phenolic acids, amino acids and reducing sugars contents and POD, PPO, APX and PAL activities in roots and leaves of tomato varieties.
