“…Besides, they also increased the number of productive tillers compared to the control plants. In a similar study, the treatments of H. gramineum crude metabolites effectively reduced the development of ShB with no significant adverse effects on the growth and yield attributes of rice plants (Duan et al 2007). Ma et al (2008) also reported the suppression of Phytophthora rot of chilli pepper using sterilised culture filtrates of Penicillium striatisporum Pst10.…”

“…Similarly, in the present study, the antifungal agents from T. roseum MMl003 culture filtrate were successfully extracted using ethyl acetate and the antifungal activity of the obtained extracts were confirmed through a well diffusion assay. In a similar study, the crude metabolites of Helminthosporium gramineum were tested for their antagonistic effects towards R. solani, where both the culture filtrate and ethyl acetate extract significantly reduced the in vitro growth of R. solani (Duan et al 2007). Kavitha et al (2005) isolated a heat-stable antifungal protein from Bacillus sp.…”

The aim of the study is to investigate the biocontrol mechanisms of Trichothecium roseum MML003 against the rice sheath blight (ShB) pathogen, Rhizoctonia solani as the former exhibited strong antagonistic activity against the latter. It has been found that T. roseum MML003 did not show any hyperparasitic interaction against R. solani. Further, it did not produce siderophores and hydrogen cyanide. However, the culture filtrate of T. roseum MML003 strongly inhibited the mycelial growth and sclerotial formation, its germination and viability, which proved that the biocontrol activity is antibiosis-mediated. The extracellular crude antifungal metabolites of T. roseum MML003 were thermo and photo-stable. Potted plant experiment showed that the crude metabolites of T. roseum MML003 effectively reduced the ShB disease in rice up to 47.7%. Thus, this study assumes significance as it provided further scope for the identification of antifungal metabolites from T. roseum MML003 and their possible use against sheath blight disease of rice.

“…Therefore, many researchers dedicate to the study of antagonistic micro-organisms to control RsB. Many organisms had been reported as the potential biocontrol agents against RsB, such as Pseudomonas fluorescens (Nagarajkumar, Bhaskaran, & Velazhahan, 2004;Nandakumara, Babua, Viswanathanb, Raguchandera, & Samiyappana, 2001), Helminthosporium gramineum Rabenh (Duan et al, 2007) and Streptomyces (Prabavathy, Mathivanan, & Murugesan, 2006). Compared with other antagonistic bacteria, Paenibacillus species, as a group, have several advantages for protection against pathogens, including the broad-spectrum activity of their antibiotics and the ability to form endospores which facilitate long-term storage and commercialisation (Emmert & Handelsman, 1999).…”

“…A variety of plant essential oils and extracts have been evaluated for the biological control of plant pathogenic as well as human pathogenic fungi (Mishra and Dubey 1990;Wilson et al 1997;Phongpaichit et al 2005). Fungal secondary metabolites produced by one fungal species have been found to possess antifungal activity towards other species of the same or different genera (Duan et al 2007;Cabras et al 2006;Vincente et al 2001). There are hardly any instances where the antifungal activity of fungal secondary metabolite produced has been tested against itself.…”

Enhanced social concern towards the ill effects of synthetic agrochemicals, their residual toxicity and resistance development in the target pests created a necessity of exploration of alternatives. Fungal biocontrol agents have been used as herbicides over two decades and research continues to enhance their efficacy comparable to synthetic herbicides. Combinations of synthetic herbicides with the fungal biocontrol agents was an approach adopted to enhance mycoherbicidal activity but had limited acceptance due to negative effects of their synthetic components. Hence a necessity for development of the formulations having least toxicity or being benign to non-target organisms was felt. The present study brings forth a new dimension of holistic and ecofriendly bioherbicidal formulations comprising of crude phytotoxins and spores of Alternaria alternata LC# 508 which enhances outstandingly its mycoherbicidal potential. Spent broth of Alternaria alternata (LC#508) exhibited toxic activity to its spores (autotoxicity) at a concentration of 50µg/ml which was used for developing five formulations FN1 to FN5. Formulations No. 5 was the best of all the formulations when evaluated by pot trails compared to control and other formulations. Disease onset and mortality was observed in 3.5 days and 5 days respectively in case of formulation No 5 (50 µg of crude spent broth + 1x 10 6 spores/ml) when compared to spore spray alone. Thus the formulation of crude spent broth and fungal spores could be developed as a cost effective and efficacious bioherbicide formulation when compared to the spores alone.
