An intensive survey was conducted on wheat diseases in 152 farmer’s fields in 36 districts of Bangladesh to assess plant responses of mature plants. During the survey, ten diseases including three majors diseases viz. Bipolaris leaf blight, leaf rust and wheat blast were identified. The maximum prevalence was recorded for Bipolaris leaf blight, with 100% incidence and 28–56% diseased leaf area (DLA). The disease was found on every cultivar in every field with varying levels of severity. Seventy-four percent of the fields surveyed had leaf rust. A significant variation in disease severity was observed among surveyed fields and cultivars. Most of the cultivars showed low to moderate disease severity with moderately susceptible to susceptible (MSS) reactions. Wheat blast, a new disease in Bangladesh, was found in 40% of fields but with low levels of infection. Among the surveyed districts, wheat fields in Bhola had higher levels of blast severity while Naogaon district had the lowest. The major wheat growing districts eg., north-western parts of the country were free from wheat blast. This survey provided fundamental information on the current status of wheat diseases which will allow for more effective management strategies.

在孟加拉国36个地区的152个农田中对小麦疾病进行了深入调查，以评估成熟植物的植物反应。在调查中，十种疾病包括三个重大疾病。鉴定出双极叶枯病，叶锈病和小麦瘟病。记录到双极叶枯病的最大流行率，发病率为100％，患病叶面积（DLA）为28-56％。该病在每个领域的每个品种中都有不同的严重程度。被调查的田地中有74％的叶子有铁锈。在所调查的田间和品种之间，观察到疾病严重程度的显着差异。大多数品种表现出低至中度的疾病严重程度，中度易感（MSS）反应。小麦爆炸，孟加拉国的一种新病，在40％的田地中被发现，但感染水平较低。在被调查的地区中，波拉州的麦田具有较高的爆炸强度，而瑙冈区的最低。主要的小麦产区，例如该国西北部，没有小麦瘟病。这项调查提供了有关小麦疾病现状的基本信息，这将有助于制定更有效的管理策略。
