“…On the other hand, total pigment content has considerably increased in all treated plants by plant extract of A. sinaica compared with non-sprayed plants. These results are in agreement of those of Mahmoud et al (2004) and El-Metwally et al (2010) who reported that plant extracts increased the photosynthetic activity of faba bean inoculated with Botrytis fabae. The stimulative effect of plant extracts on pigments biosynthesis might presumably due to the fact that these extracts increase the rate of transpiration and this will possibly increase the rate of translocation of minerals and cytokinins from root to developing shoot.…”

“…Many authors believe that latex produced from the members of Asclepiadaceae contains many bioactive components which can be used as antimicrobials (Neenah, 2013). Such results are in accordance with pervious work on the role of extracts of medicinal plants in fungal diseases control which provided successful control against this disease in laboratory and greenhouse tests (Heweidy et al, 1997;Mahmoud et al, 2004;El-Metwally et al, 2010). The efficacy of medicinal plant species may be due to induction of the resistance mechanisms in treated plants (Yamunarani et al, 2004) or cause a delay in the development of infection in early growth stage by inhibition the mycelial growth of pathogen (Krebs and Forrer, 2001).…”

“…Plant extracts have played a significant role in the inhibition of seed-borne pathogens and in the improvement of seed quality and field emergence of plant seeds. Many authors reported the effective and safe use of plant extracts for controlling seed-borne fungi (El-Metwally et al, 2010;Yoon et al, 2011;Ammar et al, 2013;Perello et al, 2013;Baka 2014b).…”

Seed samples of four Egyptian broad bean cultivars were tested for seed-borne fungi. The deep freezing method was used to isolate twelve seed-borne fungi viz., Alternaria alternata, Aspergillus flavus, A. niger, Botrytis fabae, Cladosporium cladosporioides, Fusarium oxysporum, F. solani,, Penicillium italicum, Rhizoc tonia solani, Rhizopus stolonifer, Stemphylium globuliferum and Trichothecium roseum from the broad bean cultivars viz., Giza 3, Giza 429, Giza 843 and Misr 1. Aspergillus flavus, Botrytis fabae, Fusarium oxysporum and Penicillium italicum were the most predominant fungal species. Aqueous extracts from five wild medicinal plants (Asclepias sinaica, Farsetia aegyptia, Hypericum sinaicum, Phagnalon sinaicum, and Salvia aegypti aca) which were collected from the Sinai Peninsula, Egypt were tested against the predominant fungal pathogens. All the aqueous plant extracts significantly inhibited the mycelial growth of these fungi, but the extract of Asclepias sinaica exhibited the strongest antifungal activity. The maximum seed germination rate was observed in infested Giza 843 and minimum in Misr 1. Treating seeds with plant extract of Asclepias sinaica (10%) enhanced the percentage of seed germination of all cultivars in both laboratory and pot experiments. Maximum root and shoot lengths of seedlings were recorded in Giza 843 during fungal infestation or treatment by plant extract. In greenhouse experiment, the aqueous A. sinaica extract reduced disease severity and total pigments but increased total phenolics and fruit yield.

“…Yield loss due to chocolate spot results from pod abortion and plant damage (Hawthorrne et al, 2012). Major yield reduction usually resulted from infection of flower, leaves and stems as along elliptical of reddish to chocolate brown color spots, with darker margins that are fairly defined and often a concentric circular pattern (El-Metwally et al, 2010;Hailu et al, 2014). In Egypt, this disease causes serious damage to the faba bean plant and decrease of the yield production more than 50% (El-Sayed et al, 2011;El-Banoby et al, 2013;El-Kholy, 2014) especially in the north and middle parts of the Egyptian Delta region.…”

Chocolate spot is one of the most important diseases affecting faba bean in Egypt. The field experiment was conducted for two cropping seasons with the objective of evaluating the efficacy of Trichoderma harzianum and five antioxidant agents, i.e. Vitamin C, Vitamin E, Selenium, VitaMax Plus against Chocolate spot disease incidence and severity under field conditions. Field study was performed during two successive growing seasons (2015/2016 and 2016/2017) using the bioagent T. harzianum and antioxidants individually or in combinations. All treatments were applied as faba bean foliar spray three times with 15 days interval starting at the beginning of flowering stage. Percentages of disease incidence and severity were measured for each growing season and their mean was calculated. Results showed that all applied treatments could reduce chocolate spot disease incidence at a range of 66.6 to 92.2% compared to the fungicide Diathane M45 (39.0%). Meanwhile, disease severity followed similar trend. It was reduced by a range of 38.7 up to 75.1% and 20.9% relatively to control at applied treatments of antioxidants individually or combined with T. harzianum and the fungicide, respectively. Combined treatments showed that when T. harzianum combined with either one or all of the used antioxidants, they had superior effect for reducing disease incidence and severity on faba bean plants compared to fungicide and the control. Meanwhile, all of the antioxidants in combination showed lesser suppression effect on disease incidence and severity than individual treatment. The present findings demonstrate that bio-agent T. harzianum integrated with antioxidant as foliar spray treatment can be recommended for the future use in a commercial scale for effective management of Chocolate spot on faba bean.
