In vitro Evaluation of Botanicals against Fusarium Wilt of Coriander Caused by Fusarium oxysporum f. sp. Coriandrii (L.)

Efficacy of six plant extracts viz., NSKE (Neem Seed Kernel Extract), Mentha arvensis, Allium sativum, Zingiber officinalis, Neem oil, Allium cepa were tested against the pathogen by dual culture technique in the laboratory of College of agriculture, Latur. The extract of each plant species was diluted in order to achieve respective concentrations viz., 5 and 10 per cent. Of the botanicals tested, Allium sativum was found to be significantly the most effective with least mycelial growth (0.00 mm) and highest mycelial growth inhibition (100 %) of the test pathogen(Fusarium oxysporum f.sp coriandrii), followed by Neem oil with mycelial growth of 8.00 mm and inhibition percent of 82.22. The highest colony growth and lowest percent inhibition was observed with NSKE which was 37.33 mm and 17.04 per cent respectively.
