This study is the first time report of utilization of Trichoderma spp. isolated from different tree bark from Odisha state of India for rice crop health management and higher productivity. Six isolates of Trichoderma spp. were identified based on the morphological characteristics and species determination was performed by molecular assays. One of the isolated strains determined as Trichoderma erinaceum outperformed others. Trichoderma erinaceum controlled three soil borne plant pathogens i.e. Rhizoctonia solani, Sclerotium rolfsii and Sclerotium oryzae effectively under controlled condition and R. solani and Helminthosporium oryzae under filed condition. Seed treatments with the formulated isolates improved the germination rate of rice and enhanced vigour. These parameters along with higher chlorophyll content could be related to higher yield observed in two rice varieties; Karuna and Sahabhagidhan. Among the six isolates tested, Trichoderma erinaceum treatment recorded highest yield. Significantly higher expression of some stress related enzymes was observed in Trichoderma treated plants which helped in better crop growth both under biotic and abiotic stresses. These isolates helped both the varieties to accumulate more nutrients. This study proves that Trichoderma erinaceum obtained from tree bark may be incorporated in integrated rice crop management both as biocontrol agent and biofertilizer.

该研究是木霉属植物利用的首次报道。从印度奥里萨邦的不同树皮中分离出来，用于水稻作物健康管理和更高的生产率。木霉属的六个分离株。根据形态特征进行鉴定，并通过分子分析进行物种确定。分离出的一种菌株被认为是木霉木霉（Trichoderma erinaceum）优于其他菌株。在控制条件下，木霉木霉菌能有效地控制三种土壤传播的植物病原体，即茄根枯萎病菌，罗氏菌和稻瘟病菌，以及茄枯菌和稻瘟病菌。在提起诉讼的条件下。用配制的分离物进行种子处理可提高水稻的发芽率并增强活力。这些参数以及较高的叶绿素含量可能与两个水稻品种的高产有关。Karuna和Sahabhagidhan。在测试的六种分离物中，木霉木霉处理的收率最高。在木霉处理过的植物中观察到一些与胁迫相关的酶的显着较高表达，这有助于在生物和非生物胁迫下更好地促进作物生长。这些分离物帮助两个品种积累了更多的营养。这项研究证明了木霉菌 从树皮中获得的植物可作为生物防治剂和生物肥料掺入水稻综合管理中。
