Abstract

Anthracnose of chili caused by Colletotrichum capsici is responsible for huge yield loss in Bangladesh. To avoid chemical control of the disease, the present study was aimed to observe the field efficacy of selected medicinal plants including neem (Azadirachta indica) and mahogany (Swietenia mahagoni) and a commercially available formulated Trichoderma either alone or in various combinations. Among all the treatments, combined application of mahogany leaf extract and peat soil-based Trichoderma resulted highest reduction of disease incidence (58.99%) and severity (67.19%) of the leaf over control. Similar treatment combinations also resulted the highest reduction of disease incidence (64.08%) and severity (68.97%) of fruit over control. The combined application of mahogany leaf extract and peat soil-based Trichoderma also exhibited the highest plant height (27.44 cm), number of fruits per plant (169), and fruit weight per plant (499.10 g). The findings of the present study explored the potentiality of the combined application of mahogany leaf extract and peat soil-based Trichoderma for the eco-friendly management of Anthracnose of chili.

利用配方木霉和本土药用植物对辣椒炭疽病进行环保管理

由辣椒炭疽菌引起的辣椒炭疽病是造成孟加拉国巨大产量损失的主要原因。为了避免对病害进行化学防治，本研究旨在观察包括印楝(Azadirachta indica)和桃花心木(Swietenia mahagoni)在内的精选药用植物和一种市售配方木霉单独或多种组合的田间药效。在所有处理中，红木叶提取物与泥炭土基木霉联合施用的病发率最高(58.99%)，严重程度较对照降低(67.19%)。与对照相比，相似处理组合的果实病害发生率和严重程度分别降低了64.08%和68.97%。红木叶提取物与泥炭土木霉配施的辣椒株高(27.44 cm)、单株果数(169个)和单株果重(499.10 g)最高。本研究旨在探索红木叶提取物与泥炭土木霉配施在辣椒炭疽病生态治理中的潜力。

期刊介绍： The Open Ecology Journal is an open access online journal which embraces the trans-disciplinary nature of ecology, seeking to publish original research articles, reviews, letters and guest edited single topic issues representing important scientific progress from all areas of ecology and its linkages to other fields. The journal also focuses on the basic principles of the natural environment and its conservation. Contributions may be based on any taxa, natural or artificial environments, biodiversity, spatial scales, temporal scales, and methods that advance this multi-faceted and dynamic science. The Open Ecology Journal also considers empirical and theoretical studies that promote the construction of a broadly applicable conceptual framework or that present rigorous tests or novel applications of ecological theory.
