Antifungal, Antiradical and Insecticidal Activities of Some Grass Species | Chapter 10 | Recent Progress in Microbiology and Biotechnology Vol. 4

 Poaceae is one of the economically important families of plants and includes grass-designated monocotyledonous flowering plants. Grasses are useful as fruit, fodder, essential oil sources, building materials, and medicine. The antifungal, antiradical and insecticidal activity of grass extracts, namely Paspalum conjugatum P.J.Bergius, Oplismenus compositus (L.) P.Beauv., Capillipedium huegelii (Hack.) A.Camus and Echinochloa colona (L.) Link, were evaluated in the present study. The extraction of shade-dried plant materials by maceration using methanol was carried out. Antifungal activity against two seed-borne fungi viz. was assessed by Poisoned food technique. A. and Aspergillus niger. Oh, Flavus. In addition to mycelial development, the extracts were successful in causing considerable sporulation suppression. The DPPH free radical scavenging assay calculated the anti-radical operation. The extracts were effective in dose-dependently scavenging radicals. Insecticidal activity against II instar larvae of the genus Aedes has been evaluated. The extracts resulted in 100 percent larval mortality at the tested concentration. For the production of formulations that can be used against phytopathogenic fungi, oxidative damage, and vectors that spread dreadful diseases, grasses appear to be promising tools. The purification of the active principles from crude extracts and the assessment of their bioactivity should be carried out.
