Leaf surface environment is dynamic due to the physiochemical properties of leaf surface and activity of phylloplane microflora. The present study aims to understand and explore the potential microbial bio agents on the phylloplane of the tomato to devise efficient management of their diseases by using phylloplane microflora. The study showed that phylloplane microflora associated with diseased leaves of tomato are more in number compared to healthy leaves and are a natural source of eco-friendly bioagents which may control plant pathogens. This investigation confirms that leaf surface mycobiota such as <em>Trichoderma</em> species found to be effective antagonists against <em>Alternaria solani</em> and <em>Fusarium </em>sp. of tomato as it is having mycoparasitic ability.</p> 2023-02-28T00:00:00+0530 Copyright (c) 2023 Research on Agricultural Sciences and Technology https://journals.ijroast.com/index.php/sard/article/view/20 Heterogeneous Chemical Catalysts in Bio Fuels Production- an overview 2022-02-25T05:26:00+0530 Vasanthakumar Thanigaimalai tmvasanth67@gmail.com <p>Catalystsperforming momentous aspects in transesterification of both edible and non-edible vegetable oils. At present here chemical catalysts are being investigated with their benefits and loss of points. In an extensive operation, catalysts are more helpful to reduce the cost in this heterogeneous nature of a catalyst is more useful and economical compared to homogeneous catalysts. This article reviews the role of the various heterogeneous chemical catalytic systems used in the transesterification of oils in biofuel manufacturing.</p> <p><strong>keywords</strong>: Biofuels, Chemical catalysts, Transesterification.</p> 2023-02-28T00:00:00+0530 Copyright (c) 2023 Research on Agricultural Sciences and Technology
