Study and Biological Manage of The Plant Virus Diseases

Plant virology is the study of viruses that infect plants, impacting agricultural productivity and ecosystem health. Viruses cause a range of symptoms, including mosaic leaf patterns, stunted growth, and reduced crop yields, posing a significant threat to global food security. Understanding plant viruses involves the study of their structure, transmission mechanisms, and interactions with host plants. Research in plant virology is essential for developing sustainable agricultural practices and reducing the adverse effects of virus infections on plants, ultimately contributing to food and agricultural security. The purpose of this reference paper is to discuss and provide information on research that has been conducted, including methodology, results, and data interpretation, symptoms caused, and how to manage them, innovations in biotechnology and the development of virus-resistant crop varieties. Plant viruses can be identified with RT-PCR method. In this study, the primary pair used to amplify were universal Potyvirus primer and specific PRSV primer. Application of biopesticides Trichoderma sp., Streptomyces sp.showed that the treatment of Bioside before infestation (T1) had a high mortality value of 95% compared to the treatment after infestation (T2) which was 75%, whereas without biocide mortality was low at only 15% , there was curl disease in the control reaching 37% between chili plants in all treatments.
