Percent mycelial growth inhibition

Tomato is world’s one of the largest growing vegetable crop and ranks first among processing crops. It’s production suffers with many biotic and abiotic factors. Leaf blight disease caused by different species of Alternaria is one of the most dreadful diseases of tomato, causing huge economic losses. The present study was conducted in order to evaluate the efficacy of different fungicides against Alternaria alternata, one of cause for blight disease of tomato.

Among the tested five non-systemic, three combi- products, three systemic fungicides against Peziotrichum corticolum under laboratory condition, Bordeaux mixture, Copper oxychloride, Mancozeb, Carbendazim + Mancozeb, Hexaconazole + Zineb recorded maximum (100%) mean percent inhibition of P. corticolum, followed by Cuprous hydroxide (96.39%), Propiconazole (95.56%), Captan + Hexaconazole (86.39%), Difenconazole (80.74%), Hexaconazole (74.07%), Chlorothalonil (73.92%). Among the five plant extracts (botanicals), maximum mean percent inhibition of mycelial growth (22.

A study was carried out to evaluate the efficacy of ten plant extracts against Phleospora maculans (Bereng) Allesch. both by inhibition zone technique and conidial germination technique on potato dextrose agar (PDA) medium each at three different concentrations viz. 5 percent, 10 percent and 15 percent with carbendazim 50WP (0.02%) as control. Among botanicals tested, the extract of Allium sativum (Garlic) has shown maximum inhibition of mycelial growth (66.45mm2 ), whereas, minimum inhibition was recorded in Morus alba (12.87mm2 ) irrespective of concentrations.

In vitro evaluation of systemic, non-systemic and combi fungicides against Colletotrichum gloeosporoides causing fungal fruit rot in pomegranate were carried out in the Department of Plant Pathology, College of Agriculture, Latur during the year 2017-18. Among the systemic fungicides at 1000 ppm concentration Carbendazim 50 WP showed (87.23%) inhibition of mycelial growth of fungus followed by Difenconazole 25 EC with (85.74%) and least inhibition of mycelial growth was recorded in Propiconazole 25 EC (74.66%).

Tomato is affected by a large number of diseases. Among these, collars rot disease of tomato cause by S. rolfsii is a threatening disease in eastern coastal regions of Odisha. Since, this disease is soil borne in nature, it is very difficult to control by chemical fungicides. The native rhizosphere soil of tomato was used for isolation and screening of bacterial antagonists for their efficacy and growth promotion potential. A total of 54 bacterial isolates were isolated from rhizosphere of tomato of which five isolates viz.

Among the four bioagents evaluated for their efficacy in inhibiting mycelial growth of Rhizoctonia bataticola causing dry root rot of chickpea by dual culture technique. The results indicated that T. harzianum is highly antagonistic to Rhizoctonia bataticola by suppressing its growth by 78.67 per cent. Paper towel method was also followed to test the efficacy of bioagents in suppressing the seedborne infections. Among the four bio-agents with three concentrations viz., 0.4 %, 0.8 % and 1.

The in vitro effect of certain fungicides, insecticides, and biopesticides on mycelial growth of Trichoderma harzianum was evaluated. Seven systemic fungicides, 2 contact fungicides, and 4 biopesticides were tested. A progressive increase in percent inhibition of radial growth in the fungus was observed as the concentrations of the fungicides increased.
