“…The tested IRCs may encourage some defense mechanisms i.e. oxidative enzymes, and phenolic compounds (Abdel-Monaim et al, 2015). In this study, all tested IRCs increased activity of defenserelated enzymes, including peroxidase, polyphenoloxidase, phenylalanine ammonialyase, pathogenesis-related (PR) protein (chitinase and β-1,3glucanase) in cowpea plants inoculated with M. phaseolina compared with control plants during the Egypt.…”

“…On the other hand, all the tested IRCs increased the tested growth parameters (plant height, number of branches, fresh and dry weight) and yield components (pod length, number of seeds/pods, the weight of 100 seeds and total seed yield Kg /feddan) during summer season 2017 under field conditions. Induced resistance was reported to be activated by exogenous application of KS, PG, HQ and SA (Mostafa, 2006;Abdel-Monaim and Ismail, 2010;Al-Askar et al, 2013;Thakur & Sohal, 2013;Abdel-Monaim et al, 2015 ;Ezzat et al, 2015;and Wang et al, 2017). Abdel-Monaim and Ismail (2010) reported that propyl gallate at 200 ppm was more efficient in reducing infection with damping-off, root rot and wilt diseases in pepper plants as well as increasing the seedling fresh weight, dry weight, plant height, plant branching, number of pod/ plant and pod yield/ plant.…”

ixteen isolates of Macrophomina phaseolina were isolated from the roots of cowpea showing charcoal-rot collected from different locations in New Valley Governorate. All the obtained isolates were able to attack cowpea plants (cv. Balady) causing charcoal rot on the basal stem with various degrees of disease severity. Isolate No. 14 was the most aggressive one in this respect causing 85.8% charcoal rot. Potassium silicate (KS), propyl gallate (PG), hydroquinone (HQ) and salicylic acid (SA) at 1, 5 and 10 mM were used in this investigation as promising inducer resistance chemicals (IRCs) for controlling the disease in vitro and in vivo. Results illustrated that all tested IRCs had little effect on the growth of M. phaseolina at different concentrations in vitro. In addition, the inhibition of the growth was slightly increased by increasing the IRCs concentrations. Under greenhouse (New Valley Agric. Res. Station) and field conditions (New Valley Agric. Res. Station at El-Kharga and East Al Owainat Res. Station) all the tested IRCs significantly decreased charcoal rot compared to the check treatment (control). Both PG and HQ were the most efficient ones in decreasing the severity of the disease. On the contrary, both SA and KS recorded the lowest protection against charcoal rot severity. Also, all the tested IRCs significantly improved cowpea plant growth parameters, i.e. plant height, No. of branches/plant, fresh and dry weight of plants (kg/feddan) and yield components, i.e. pod length (cm), No. of seeds/pod, the weight of 100 seeds, total seed yield (Kg/ feddan) compared with control during summer season 2017. Cowpea seeds soaked in PG at 5 mM recorded the highest growth and yield components in both locations. While HQ recorded the lowest ones. Analysis of plant mineral compositions showed a significant increase in contents of nitrogen (N), potassium (K), phosphorus (P) and crude protein in cowpea plants raised from cowpea seeds treated with any of the tested IRCs compared with control plants during growing summer season 2017. The highest increase was obtained for these mineral contents when cowpea seeds were soaked in SA except for potassium in East Al Owainat. While, KS treatment recorded the lowest plant mineral contents of estimated minerals in both locations, except for potassium in East Al Owainat.

“…The highest reduction was recorded using potassium silicate followed by salicylic acid. A number of studies showed the effectiveness of potassium silicate in inhibiting the mycelium growth of R. solani , F. solani , F. oxysporum , F. equiseti , and F. semitectum [ 69 ], and the germination of powdery mildew conidia by 40–60% [ 70 ]. In addition, the application of salicylic and ascorbic acids caused a significant decrease in the linear growth of F. oxysporum , F. solani , and M. phaseolina [ 6 ].…”

The possibility of inducing systemic resistance in roselle against root rot and wilt diseases was investigated using biotic and abiotic inducers. The biotic inducers included three biocontrol agents (i.e., Bacillus subtilis, Gliocladium catenulatum, and Trichoderma asperellum) and two biofertilizers (i.e., microbein and mycorrhizeen), while the abiotic inducers included three chemical materials (i.e., ascorbic acid, potassium silicate, and salicylic acid). In addition, preliminary in vitro studies were conducted to evaluate the inhibitory activity of the tested inducers on the growth of pathogenic fungi. The results show that G. catenulatum was the most efficient biocontrol agent. It reduced the linear growth of Fusarium solani, F. oxysporum, and Macrophomina phaseolina by 76.1, 73.4, and 73.2%, respectively, followed by B. subtilis by 71.4, 69, and 68.3%, respectively. Similarly, potassium silicate was the most effective chemical inducer followed by salicylic acid, each at 2000 ppm. They reduced the linear growth of F. solani by 62.3 and 55.7%; M. phaseolina by 60.7 and 53.1%; and F. oxysporum by 60.3 and 53%, respectively. In the greenhouse, all inducers applied as a seed treatment and/or foliar spray strongly limited the development of root rot and wilt diseases. In this regard, G. catenulatum, at 1 × 109 CFU mL−1, achieved the highest values of disease control, followed by B. subtilis; while T. asperellum, at 1 × 105 CFU mL−1, recorded the lowest values. In addition, the plants treated with potassium silicate followed by salicylic acid, each at 4 g/L, recorded the highest disease control compared to ascorbic acid at 1 g/L, which had the lowest values. The mixture of mycorrhizeen + microbein (at 10 g/kg seeds) was the most effective compared to either of them alone. All treatments, applied alone or in combination in the field, significantly reduced the incidence of diseases. The most effective treatments were a mixture of G. catenulatum (Gc) + Bacillus subtilis (Bs) + Trichoderma asperellum (Ta); a mixture of ascorbic acid (AA) + potassium silicate (PS) + and salicylic (SA); G. catenulatum; potassium silicate; and a mixture of mycorrhizeen + microbein. Rhizolix T had the highest disease-reducing efficacy. In response to the treatments, significant improvements in growth and yield, changes in biochemicals, and increased activities of defense enzymes were achieved. This research points to the activity of some biotic and abiotic inducers that can play a vital role in managing the root rot and wilt of roselle through the induction of systemic plant resistance.

This study was conducted to evaluate the efficacy of some chemical and biological substances, individually or in combination in reducing fusarium root rot disease in soybeans caused by the fungus Fusarium solani. The results of laboratory evaluation showed that A. chroococcum bacteria achieved 58.90% inhibition by using dilution 10 -7 . Whereas, the biochar scored 100% inhibition rate at a concentration 4%, while the potassium phosphate (K 2 HPO 4 ) scored a complete and 100% inhibition of the growth of the fungus at of 200 mM concentration. At greenhouse conditions, the mixing treatment A .chroococcum with biochar was performed in the presence of pathogenic fungi, and treatment of K 2 HPO 4 with A.chroococcum and biochar with pathogenic fungi, was the most efficient in reducing the incidence and severity of infection with F. solani which was 0.00 and 0.00% respectively, which did not differ significantly from the treatment of K 2 HPO 4 with A.chroococcum with pathogenic fungi, which was 6.67 and 3.33% respectively, compared to the percentage and severity of infection in the control treatment with, 76.67 and 75.00% respectively, as well as their cause of The fresh and dry weight of the plant was significantly increased among their treatments. The factors also showed an efficiency in inducing systemic resistance by increasing the peroxidase enzyme activity 7 and 14 days of adding the pathogen, compared to the treatment (without pathogenic fungi. The two mixing treatments between K 2 HPO 4 with A .chroococcum and biochar with pathogenic fungi and the addition treatment of mixing A .chroococcum with biochar in the presence of the pathogen were 64.00, 70.00, 63.17 and 68.37 respectively the rate of change in photosynthesis / min / g fresh weight of plant leaves. The rate of change of plant leaves was successively, while the rate of change of the enzyme was achieved by the comparison treatment (without pathogenic fungi), which was 22.27 and 23.33 rate of change by photosynthesis / min / gm fresh weight of plant leaves respectively, followed by the remaining treatments.
