%X Wheat blast, caused by a fungal pathogen, <i><span style=\"font-family:Verdana;\">Magnaporthe oryzae Tritichum </span></i><span style=\"font-family:Verdana;\">(</span><i><span style=\"font-family:Verdana;\">MoT</span></i><span style=\"font-family:Verdana;\">) pathotype (wheat isolates), was
first reported in Bangladesh among Asian countries in 2016. It is a serious
disease of wheat causing yield failures and significant economic losses during
epidemic years. Extensive use of persistent synthetic pesticides to control
notorious wheat blast imposes enormous threat to human health and environment.
In addition, the increasing demand for organic food has stimulated people to
look for alternative methods. Nowadays, the need for synthetic chemical-free
agricultural practices is gaining importance due to effective in managing crop
pests, inexpensive, biodegradable, easily available and have low toxicity to
non-target organisms. In order to identify active plants, 12 kinds of methanol
extracts obtained from 12 medicinal plants were conducted </span><i><span style=\"font-family:Verdana;\">in vitro</span></i><span style=\"font-family:Verdana;\"> to test the effect against </span><i><span style=\"font-family:Verdana;\">Magnaporthe oryzae Triticum </span></i><span style=\"font-family:Verdana;\">(</span><i><span style=\"font-family:Verdana;\">MoT</span></i><span style=\"font-family:Verdana;\">) pathotype. The remarkable
inhibitory activity {(29.6 ¡À 01.5)
mm, (25.1 ¡À 01.0) mm and (20.0 ¡À 02.0) mm zone of inhibition)} exhibited by the extracts (5 mg/disk)
obtained from </span><i><span style=\"font-family:Verdana;\">Artemisia indica</span></i><span style=\"font-family:Verdana;\"> (Nagdona), </span><i><span style=\"font-family:Verdana;\">Persicaria orientalis</span></i><span style=\"font-family:Verdana;\"> (Bishkatali) and </span><i><span style=\"font-family:Verdana;\">Clerodendrum indicum</span></i><span style=\"font-family:Verdana;\"> (Bamonhati), respectively. Other medicinal plant extracts did not show any
significant or no activity at all. Therefore, the three plant extracts might be
a promising source for developing natural fungicides against wheat blast.</span>
