Abstract
Eggplants showing stunting and wilting appearance and seeds were collected from Hyderabad and Mirpurkhas districts. Nine fungi including four predominant pathogenic fungi Fusarium solani, Rhizoctonia solani Macrophomina phaseolina and Fusarium oxysporum, were found associated with these samples. Eight fungicides viz., Thiophanate-methyl, Fosetyl-aluminium, Propineb, Carbendazim, Copper oxychloride, Mendipropomide, Difenoconazole and Metriam were evaluated with five different concentrations viz., 1, 10, 100, 1000 and 10000 ppm by food poisoning method. Variation in growth reduction observed with changing concentrations of fungicides. Higher concentrations of tested fungicides were more effective than medium and lower ones. Difenoconazole at its all doses (1-10,000 ppm) caused more than 50% inhibition of F. solani. Among 40 different treatments only Thiophanate-methyl at 10,000 ppm and Carbendazim 10,000 ppm and 1000 ppm causes more than 50% growth reduction of R. solani as compared to control. Thiophanate-methyl, Carbendazim and Difenoconazole 1-10,000 ppm dose cause more than 50% growth reduction of M. phaseolina. Mendipropomide at its highest used dose (10000 ppm) cause only 43% inhibition of Fusarium oxysporum. Carbendazim and Thiophanate-methyl found equally effective against above mentioned pathogens.
