Title

Suppressive capability of fungicides and botanical extracts against Alternaria polianthi Causing leaf spot of Tuberose ( polianthus tuberosa L ).

Abstract

Alternaria species causing diseases to horticultural and medicinally important ornamental plants. In the present study the experiment was made on the leaf spot disease of tuberose ( polianthus tuberosa ). This fungus produces profuse dark brown to blackish mycelium with transverse as well as longitudinal septate conidia on the czapex dox agar medium. In this study attempts was made to investigate the constraint capability of some fungicides and plant extracts against Alternaria polianthi causing leaf spot of tuberose. In vitro study fungicides, Viz. mancozeb, carbendazim, coper oxychloride,chlorothalonil and propiconazole and Leaf extracts of Saraca indica Linn. Cassia auriculata L. pongamia pinnata L Vitex negundo L., Boerhavia repens Var. diffusa (L.). Hook. Tithonia diverisfolia A.Gary used against the pathogen by the Poisoned food technique. Among the tested fungicides mancozeb 1000 ppm was found most effective against the pathogen it shown 90.74% Percent of inhibition, followed by carbendazim 87.41%, copper oxychloride 84.07% and cholorothalonil shown 81.85% and propicanozole shown 80.74 % of growth inhibition . Among the plant extracts 50 % alcoholic leaf extract of all tested plants inhibited the growth of the pathogen. 100 % aqueous leaf extract of Saraca indica was quite superior over the other tested plant extracts, it shown maximum 86.33% percent of growth inhibition .
