Medicinal Plants, A promising Source of Natural Fungicides against <i>Magnaporthe oryzae Triticum</i>, Causal Agent of Wheat Blast

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