An interesting question . I think , perennial crops are better equipped than annual field crops to biofertilization response. Please have a look at enclosed PDF, interesting indeed....

Dear Dr. Essalmani

In the attached article, Trichoderma harzianum-enriched biofertilizer played significant role in both yield and quality improvement of tomato. Combined application of biofertilizer and chemical fertilizer (especially 50 % BioF + 50 % N:P:K) enhanced vegetative and reproductive growth, yield and nutritional quality of tomato by slow and steady release of nutrients to the plants than the sole application of N:P:K fertilizer.

Thank you, Anoop Kumar Srivastava and Seied Mehdi Miri for your help

Thanks for question and answers. Especially Dr. Miri‘s question always helpful for specific Research areas.

Trichoderma is best but its efficacy will be affected by some factor, So check then apply its

Abstract:

In order to study the effect of Trichoderma based bio-fungicide on bio control of Pythium ultimum disease in lettuce, this study was carried out in a randomized complete block design with four replications. The treatments consisted of plants treated with wild (un-irradiated) and mutant Trichoderma in both inoculated and un-inoculated conditions and control plant (without any fungal treatment). The results showed that Trichoderma (wild and mutant) significantly reduced the incidence of disease and significant development of the root system of the plant, and inoculation with mutant Trichoderm isolate has no adverse effects on plant growth. To investigate the effect of using this bio-fungicide on mammalian tissues, two experiments were conducted on feeding with mouse with lettuce irrigated with Trichoderma (mutant and wild) and drinking water containing Trichoderma spores (mutant and wild). Then inflammatory trend in the vital organs and blood factors were measured in all mouse after two months of treatment. According to the findings of this study, despite the significant impact of Trichoderma's biological fungicide on reducing the damage to lettuce, a more precise assessment of the impact of these biological agents on the mammalian body should be considered before commercializing such compounds.

Thank you for all information

I have used Trichoderma harzianum in many experiments on some Citrus root stocks and three Olive cultivars transplants and and obtained excellent results, but the use of bacteria of species Pseudomonas fluorescence and Azospirillum brasilinse It gave me better results when used in Apricot, Pomegranate and Ber crops .

Dr Ali , appreciating your valued feedback, dont you think , time has come to introduce a paradigm shift to consider such microbes possessing twin ability , to act as PGPG on one hand and antagonists to soil borne pathogens , in order to harness better potential of these microbial agents.
