Effectiveness of ethanolic extract of Lippia palmeri Wats for the management of Fusarium spp. in chickpea seeds

Chickpea is a crop of world importance due to its nutritional value; however, seed and root diseases caused by Fusartum spp. affect the harvest and for its control. synthetic fungicides are applied: nevertheless, natural products based on plant extracts niay be an option for the sustainable niaiiagement of this crop diseases. The objective of this research was to determine the in ri/no and in rico efficiency of the Lippia pa/men extract for the control of Fusarium oxysporuni and F. so/ani in chickpea seeds. To Pl)A media, 500. 1000 and 2000 ppm from ethanolic extract of F. painteri plus one agar disc of each pathogen, and tl e inhibition of mycelial growth was quantified Chickpea seeds were submerged in each concentration ofF. pa/men for Sand 10mm later, each seed was inoculated with F. oxvsporum and F. soluni and the disease incidence and germinated seeds w crc determined, The three concentrations of F. palnu'ri inhibited 1)0th phytopathogens iii ri/ru. ln the seeds, F. painteri ethanolic extract decreased the incidence of' F. so/ala and kept germination above 80 %. l'or F.oxysporurn only the highest dose of the ethanolic extract and the longest exposure time decreased tl e incidence by 20 % and germination was less than 25 %.The ethanolic extract of F. pa/men can he an option to decrease diseases caused by phytopathogenic fungus of' the soil in chickpea seeds.
