DIMOCARPUS LONGAN (JUNGLI LYCHEE) EXTRACT ACTS AGAINST MAGNAPORTHE ORYZAE TRITICUM, CASUAL AGENT OF WHEAT BLAST (Pages : 24 - 28)

Rice blast, caused by a fungus, Magnaporthe oryzae Triticum (MoT) pathotype, is an important and serious disease of wheat worldwide. The disease has been reported to cause yield losses up to 100%. Extensive use of persistent synthetic pesticides to control notorious wheat blast imposing enormous threat to human health and environment as well as developing resistance in fungal population to fungicides. Additionally, increasing demand for organically produced foods, stimulated search for alternative approaches. Nowadays, botanical pesticides are gaining popularity due to effective in managing crop pests, inexpensive, biodegradable, easily available and have low toxicity to non-target organisms. With a view to identify active plant extracts, 11 extracts (five ethyl acetate and six methanol extracts) were subjected to in vitro screening test against Magnaporthe Oryzae Triticum (MoT) pathotype. The marked inhibitory activity (20 mm zone of inhibition) of methanol extract (1 mg/disk) obtained from Dimocarpus longan (jungli lychee) was shown against MoT. This plant extract can thus be used for developing natural fungicides against wheat blast. Other medicinal plant extracts showed little or no activity at all.Download
