“…The isolated fungi were previously isolated from the roots of pea plants and proved their pathogenicity (Abada et al,1992, Masoodi et al,2000, Kraft and Pfleger,2001, Zue, 2003, Hamid, 2012, Sharma-Poudyal et al,2015and Muhanna et al, 2018 The tested bioagents and the CRIs resulted in significant reduction to the linear growth of both F. solani and R. solani compared with control treatment. This reduction was gradually increased by increasing the incorporated concentration to PDA medium.…”

The isolated fungi of Alternaria sp., Fusarium semitectum, F. solani, Rhizoctonia solani, and fungus-like Pythium ultimum caused pre-and post-emergence damping-off to pea plants. In the pathogenicity test, the fungus Fusarium solani showed the highest percentages of pre-and postemergence damping-off followed by Rhizoctonia solani and F. semitectum. Meanwhile, Alternaria sp. caused the least figures of pre-and post-damping-off followed by fungus-like Pythium ultimum. Data demonstrated that the tested bioagents Bacillus megaterium, B. subtilis and B. thuringiensis and the CRIs resulted in a significant reduction to the linear growth of both F. solani and R. solani compared with control treatment with reduction-concentration dependent. In addition, CRIs were less efficient in this regard than the bioagents. The obtained results revealed that soaking pea seeds in 100 mM Bion (BTH) for six hours, then pelleting them with supernatant of B. megaterium resulted in a significant reduction to the incidence of damping-off and root-rot severity caused by both tested fungi. Also, a significant increase to the plant height and the produced green pods yield was recorded compared to control treatment. Moreover, the most efficient treatment in reducing damping-off and root-rot severity and increasing each of plant height, number of pods/ plant and average weight of green pods (g) / plant was the combination with Bion and B. megaterium. Treating pea seeds with the tested Bacillus strains and the CRIs resulted in increasing of the total phenols in the roots pea plants compared with the plants of untreated seeds. The study recommends treatment of pea seeds in the mixture of Bion and B. megaterium to protect the roots and seedlings and improve the plant characteristics.

Damping-off of common bean (Phaseolus vulgaris L.) is considered to be of paramount importance causing yield losses that exceed 50% and has been reported in many countries worldwide. In this study, damping off and root rot fungi and others associated with common bean root rot in Egypt were isolated and were identified as Rhizoctonia solani Kuhn, Macrophomina phaseolina (Tassi) Goid and Sclerotium rolfsii Sacc. Non-traditional control measures with chemicals as sulphuric acid were tried in literature. It has been shown in the present study that application of high rates of H2SO4 to bean plants have had indirect effect on disease(s) progress. Plants, 45 days after the treatment, were evaluated pathologically. Two dry bean Nebraska and Nahda cultivars reacted differently to the isolated pathogenic fungi. Pre and Post emergence damping off caused by mixture of the isolated fungi on Nahda cv. treated with sulphuric acid compared to Nebraska cultivar showed greater susceptibility to the disease. The results showed significant differences in shoot /root ratio(s) either on fresh or dry weights bases as influenced by H2SO4 strength, i.e., the concentration. Different intensity values of nodulation in both varieties were found to follow the recorded difference in damping off susceptibility. The same conclusion may be applied to the inherent difference in varietal susceptibility to infection by nodule bacteria. Root rot severity was significant and also determination of microbial density, 45 days after application. The concentration (0.2N) of sulphuric acid resulted in the decrease of each of N, P and K in most cases. Further studies are needed to include the possible effect of induced resistance in common bean induced by sulphuric acid. Field trials may be advised.

“…Trichoderma harzianum, Rhizobium sp., and B. subtilis were used as biological agents to manage pea root rot complex and improve plant growth parameters according to the study done by Muhanna et al (2018). The results revealed that the root rot complex was caused by R. solani, F. oxysporum, Thielaviopsis basicola, and S. sclerotiorum.…”

Background Root rot pathogens reported to cause considerable losses in both the quality and productivity of common bean (Phaseolus vulgaris L.) and pea (Pisum sativum L.). It is an aggressive crop disease with detriment economic influence caused by Fusarium solani and Rhizoctonia solani among other soil-borne fungal pathogens. Destructive plant diseases such as root rot have been managed in the last decades using synthetic pesticides. Main body Seeking of economical and eco-friendly alternatives to combat aggressive soil-borne fungal pathogens that cause significant yield losses is urgently needed. Trichoderma emerged as promising antagonist that inhibits pathogens including those inducing root rot disease. Detailed studies for managing common bean and pea root rot disease using different Trichoderma species (T. harzianum, T. hamatum, T. viride, T. koningii, T. asperellum, T. atroviridae, T. lignorum, T. virens, T. longibrachiatum, T. cerinum, and T. album) were reported both in vitro and in vivo with promotion of plant growth and induction of systemic defense. The wide scale application of selected metabolites produced by Trichoderma spp. to induce host resistance and/or to promote crop yield, may represent a powerful tool for the implementation of integrated pest management strategies. Conclusions Biological management of common bean and pea root rot-inducing pathogens using various species of the Trichoderma fungus might have taken place during the recent years. Trichoderma species and their secondary metabolites are useful in the development of protection against root rot to bestow high-yielding common bean and pea crops.
