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. The extracts of Datura stramonium inhibited the maximum conidial germination of 82.24 percent, whereas, Urtica dioica inhibited the minimum conidial germination of 13.85 percent irrespective of concentrations. At 5 percent concentration, Datura stramonium showed the highest mycelial inhibition of 48.17mm2, whereas, maximum conidial inhibition of 79.16 percent was recorded in Allium sativum. At 10 percent concentration, highest mycelial inhibition of 63.50mm2 was recorded in case of Allium sativum, whereas, highest conidial inhibition of 83.90 percent was recorded in Datura stramonium. At 15 percent concentration, Allium sativum inhibited highest mycelial growth of 87.97mm2, whereas, Datura stramonium inhibited highest conidial germination of 86.45 percent.
