New Strategy for Managing Damping-off and Root Rot Disease of Cucumber Caused by Rhizoctonia solani by Seed Soaking in Formula of Antioxidant with Micronutrients

Nitric Oxide as a Beneficial Signaling Molecule in Trichoderma atroviride TRS25-Induced Systemic Defense Responses of Cucumber Plants Against Rhizoctonia solani

“…In the plants not pretreated with TRS25, R. solani caused progression of disease symptoms in roots and then in aboveground organs which had no direct contact with the pathogen. The observed disease symptoms were similar to those described in different plants including rice, tomato and cucumber, such as root rot, foliar blight, and damping-off (Singh et al., 2002; Bartz et al., 2010; Yousef et al., 2013; Jaiswal et al., 2015). Pretreatment of plants with T. atroviride TRS25 significantly reduced DI in cucumber plants.…”

“…Induction of plant defense mechanisms or “sensitization” of plants by prior application of Trichoderma is thought to be a promising plant protection strategy. However, their beneficial influence on plants depends on the Trichoderma strain, plant species, pathogen, and soil-climate conditions (Harman et al., 2004; Singh et al., 2010; Hermosa et al., 2012; Yousef et al., 2013; Gomes et al., 2017).…”

“…As the use of chemicals and changes in the cultivation practices are not sufficiently effective in the protection of plants against R. solani , the induction of defense responses and resistance to the pathogen by Trichoderma has emerged as potential supplement of crop protection (Singh et al., 2002; Bartz et al., 2010; Saberi et al., 2013; Yousef et al., 2013; Anderson et al., 2017). Firstly, some Trichoderma strains were listed among the effective antagonistic or mycoparasitic BCA of R. solani (Harman et al., 2004; Yousef et al., 2013). Further analyses suggested that resistance induction together with overexpression of different pathogenesis related proteins (PR) might be one of the ways of plant protection against R. solani as well.…”

“…Further analyses suggested that resistance induction together with overexpression of different pathogenesis related proteins (PR) might be one of the ways of plant protection against R. solani as well. However, this process requires further elucidation (Yousef et al., 2013; Mayo et al., 2015). Because our previous results strongly pointed to T. atroviride TRS25 as BCA of R. solani , we decided to study the signaling network involved in the effective cucumber defense against this pathogen, induced by TRS25.…”

Impact of Antioxidants and Micronutrients as Fungicides Alternatives in Improvment the Antagonism of Trichoderma spp. Against Sclerotinia sclerotiorum

“…Addition of micronutrients particularly borax increased the biocontrol activity of T. viride against F. oxysporum f. sp cubense (Sanjeev 2008). In our previous work Yousef et al (2013) noticed the direct effect of some micronutrients mixtures and antioxidants which showed good results in inhibiting the growth and sclerotia formation of Rhizoctonia solani. In this article, improving the growth and antagonicity of four Trichoderma spp.…”
