Isozymes are one of the key control mechanisms for cellular protection against versus infection (Harb et al, 2010;Akladious et al, 2019;El-Fawy et al, 2021). Induction of these isozymes plays a vital role in cellular defense against oxidative stress (El-Beltagi et al, 2010;Contreras-Zentella et al, 2022;Zulfiqar and Ashraf, 2022).…”

Plant growth promoting fungi (PGPF) were employed in the present study to biocontrol Fusarium wilt disease in pepper plants. Two of the five fungal isolates were chosen based on biochemical characteristics such as their production of hydrocyanic acid, siderophores, and IAA, phosphate solubilization, and in vitro antifungal activities. The most potent fungal isolates were identified as Penicillium expansum (P. expansum) and Trichoderma harzianum (T. harzianum). Using GC-MS, it was found that PGPF extracts contain compounds with antifungal activity, antioxidants, and plant growth stimulators. The combined effect of T. harzianum and P. expansum increased the protection against fusarial wilt by (76.74%), followed by T. harzianum by (50%), then P. expansum by (17.64%). Significant improvement because of using the mixture (T. harzianum and P. expansum) showed an increase in shoot length (59.4%), root length (129%), and number of leaves (52.6%). Chlorophyll A and B levels in infected plants were consistently raised by 28.71% and 67.58%, respectively; as a result of application the mixture (T. harzianum and P. expansum). Also, there was an increase in soluble proteins and carbohydrates in infected plants treated with (T. harzianum) by 25.42% and 31.78% over untreated infected plants, respectively. It could be recommended that the use of targeted PGPF strains, especially a mixture of T. harzianum and P. expansum could be commercially used as therapeutic nutrients against Fusarium wilt of pepper plants.

“…According to the latest statistical statement (FAOSTAT, 2019); the area cultivated with tomatoes in Egypt is around 450,000 acres with a production of 7,297,108 tons. The soil borne pathogens can affect tomato and the most important of these are the soil borne fungal pathogens including Fusarium spp., Rhizoctonia solani and Sclerotium rolfsii (Abdel-Monaim, 2012;El-Fawy et al, 2021;El-Mohamedy et al, 2014;Saad 2006). Both R. solani and F. solani produced damping-off disease causing major economic losses in many crops.…”

Fusarium root rot disease of tomato caused by Fusarium solani is one of the most important tomato diseases and causes severe problems in all production regions. The aim of the current study was to evaluate the efficacy of some Trichoderma isolates and Pseudomonas fluorescence to control this disease in vitro and in vivo. In laboratory experiments, the effect of four Trichoderma isolates, i.e. T. harzianum (T1), T. harzianum (T2), T. reesei and T. asperellum (T34) and one isolate P. fluorescence. Data indicated that all the tested isolates of biocontrol agents were able to inhibit the mycelial growth of the pathogen with variation in their antagonistic capability. In general, T. asperellum (T34) exhibited the highest antagonistic effect toward the pathogen, followed by T. harzianum (T2). Under greenhouse conditions, application of bio control agents as a soil treatment led to decrease in disease severity of tomato root rot disease compared to the control treatment. Data indicated that T. reesei treatment exhibited the highest reduction in the disease severity of root rot compared to other treatments in both seasons. Moreover, application of these treatments significantly enhanced plant height (cm), fresh and dry weight (gm). Laboratory estimates showed that the tested bio control agents increased catalase (m/g fresh weight), peroxidase and polyphenol oxidase (m/g f. w) in treated tomato plants compared to infected and healthy control. Furthermore, treated tomato plants contained a high level of total phenol contents (TPC) compared to untreated plants.

Essential oil nanoemulsions have received much attention in the last period for controlling of fungal plant pathogens. In this study, thyme oil nanoemulsion (TONE) was successfully prepared from thyme oil which extracted from Thymus vulgaris (T. vulgaris). The prepared TONE was characterized using DLS, Zeta potential, and TEM analyses. Results revealed that, TONE has spherical shape with size 32.7 nm. Moreover, results illustrated that TONE exhibited promising antifungal activity against Fusarium oxysporum (F. oxysporum) with minimum fungicidal concentration (MFC) 5 mg/ml. Additionally, TONE concentrations 1, 2, 3 and 4 mg/ml reduced the growth of F. oxysporum with percentages 7.78, 31.1, 52.2 and 67.8 % respectively. Disease index (DI) of Fusarium wilt reached the maximum rate by (85 %) in the Foeniculum vulgare (F. vulgare) plant infected with F. oxysporum. Application of TONE treatment on infected plants led to a decrease in DI to (17.5%) and an increase in the percentage of protection to (79.4%). Furthermore, DI was decrease to 42.5% with protection percentage 50% in the case of infected plant with TOE. Moreover, TOE, TONE played an important role in improving plant immunity by increasing phenol, proline, and antioxidant enzymes (POD&PPO) activities, as well as reducing oxidative stress by reducing (MDA & H2O2). Results revealed that TONE led to significant increase in free proline in compared to TOE. We can conclude that TOE, TONE are considered eco-friendly safe strong inducers of F. vulgare plant immunity alternatives to difenoconazole against fusarial wilt disease to preserve plant, soil, and human health.
