Potential fungicides and plant extracts against Fusarial wilt of brinjal

Abstract

Antifungal potentials of nine fungicides and eight plant parts extracts were tested in opposition to Fusarium oxysporum Schlecht. and F. solani (Mart.) Sacc. – the two pathogens, isolated from wilted roots of brinjal plants. Efficiency gradients observed in the present study expressed that Bavistin and Tall were the best inhibiting agent against the in vitro growth of the test pathogenic fungi. Among aqueous extracts of eight plant parts significant inhibition of the growth of the pathogens was observed with Azadiracta indica (leaf), Zingiber officinale (rhizome) and Asparagus racemosus (root) at 20% concentration.

In vitro effects of plant extracts and fungicides to control wilt of brinjal (Solanum melongena L.)

“…Greengel and Dithane showed 68.28 and 48.57% growth inhibition of Fusarium solani, respectively at 500 ppm ( Table 2). Bashar et al (14) reported the effects of Bavistin, Dithane and Tall on the radial growth of Fusarium oxysporum and F. solani at 400 ppm only. Chakraborty et al (11) reported that, at 0.5% dose, bavistin happened to be the most efficient one contributing the highest inhibition (83.7%) of growth of the F. solani causing wilt of brinjal under in vitro condition.…”

“…In recent years, some workers on the fungi toxicity of extracts of various parts of higher plants have indicated the possibility of their exploitation as natural fungi toxicants for controlling plant diseases (12)(13)(14)(15) . Plant metabolites and plant based pesticides appear to be one of the better alternatives as they are known to have minimal environmental impact and danger to consumers in contrast to the synthetic pesticides (16) .…”

In vitro efficacy of fungicides and plant extracts on the growth of Colletotrichum gloeosporioides (Penz.) Penz. & Sacc. and Sclerotium rolfsii Sacc. the causal organisms of anthracnose and soft rot of jute

“…Various workers in different countries evaluated the efficacy of various fungicides against Colletotrichum spp. and S. rolfsii under laboratory and field conditions (2)(3)(4)(5)(6)(7)(8)(9) . Very few works have been done for the control of anthracnose and soft rot diseases of jute by fungicides and plant extracts.…”
