Bioactivities of Allium longicuspis Regel against anthracnose of mango caused by Colletotrichum gloeosporioides (Penz.)
The present study focused on the effect of Allium longicuspis extracts (ALE) against anthracnose of mango fruit. In vitro tests (mycelial growth and conidial germination) showed that, ALE concentrated from 0.75 to 2.5 g L−1 completely inhibited the growth of Colletotrichum gloesporioides. Cytoplasmi...

| Summary: | The present study focused on the effect of Allium longicuspis extracts (ALE) against anthracnose of mango fruit. In vitro tests (mycelial growth and conidial germination) showed that, ALE concentrated from 0.75 to 2.5 g L−1 completely inhibited the growth of Colletotrichum gloesporioides. Cytoplasmic discharge, mycelial and conidial blasts were clearly observed when applied with ALE. The minimum effective concentration (MEC) of ALE at 0.75 g L1 can be applied as protective, curative and simultaneous treatment in mango fruit to inhibit the anthracnose infection. Efficacy of garlic extract was relatively superior to synthetic fungicide based on protective, curative and simultaneous treatments. Twenty chemical components were detected in ALE based on GCMS analysis (Table 1). The six major components were the following: oleyl alcohol, methyl ether (42.04%), γ-sitosterol (15.85%), , 24-norursa-3.12-diene (5.62%), 1-octadecanol methyl ether (4.23%), n-pentadecanol (3.95%) and 2-vinyl-4h-1 3-dithiine (3.76%). The findings support the potential use of ALE as an alternative to synthetic fungicide. © 2020, The Author(s). |
