Chickpea wilt management by Plant extract Biocontrol agent & Fungicide

After 4 & 7 days of inoculation plant extracts C. procera suppressed the growth of the test fungus from 21.00 to 0.00 mm at 10 to 40% & 38.92 to 2.75 mm at 10% to 40% con.,where as the 2nd & 3rd effective plant extracts were A. indica & W. somnifera while Z. officinalis & A.cepa have shown the similar growth.The highly effective fungicide was hexaconazole which reduces (92.26%) growth,while the 2nd effective was thiophenate which reduces (77.92%) growth of the test fungus. The least effective fungicide was carbendazim which reduces(73.38%) growth. At 10 ppm con. of fungicide the growth varies from 0.00 to 5.25 mm while the growth of control was 34.22 mm. Effects of various bioagents on radial growth of test fungus was checked by the A. niger after 4 days of inoculation was 31.75 mm & the growth in control was 34.75 mm. Growth reduces by A. niger was (8.63%). T.harzianum checked the growth of test fungus. After 5 days of inoculation growth of the test fungus in presence of T.harzianum was observed 41.67 mm & the growth in control was 47.17 mm. Growth reduces by T.harzianum was(11.65%)after 7 days of test fungus reduces by T. harzianum (42.26%)& by A.niger(56.00%) over control 72.17.
