The Economic Impact and Integrated Management Strategies against Tomato Yellow Leaf Curl Virus (TYLCV): A Review

The plants viruses have been examined to study the economic losses associated with agricultural crops and the viruses that represent a focus of attention of this study, in particular the Tomato Yellow leaf curl virus (TYLCV) and its impact on tomato productivity in Iraq. A study highlights the destroy produced by this virus, which can reach up to 100% in severe cases. This review aims to provide a comprehensive overview of the economic impact of TYLCV on tomato productivity in Iraq and to discuss integrated management strategies. It addresses the significant yield losses, which can be up to 100% in severe cases. In addition, it examines the effect of the virus on the chemical composition of fruit and reduces both nutritional value and marketing. The study emphasizes that controlling plant viruses requires integrated strategies, including development of resistant cultivars, the use of chemical, biological and agronomic control measures within an integrated management framework has been stressed as the best way to control plant viruses. It also underscores the need for enhanced scientific research and for improving farmers’ awareness. Additionally, it explores the effects of plant viruses on the chemical composition of associated plants, such as some mineral elements and plant hormones and how the plant responses resulting from the interaction of the host plant and the virus can lead to the decay of crop quality. Virus management strategies, including resistant cultivars, agricultural control methods such as the use of biological control methods and nanotechnology, in some limited cases, chemical pesticides used in a responsible manner, are discussed. Overall, this review highlights the urgent need for robust, integrated management strategies to mitigate the devastating effects of TYLCV and enhance the sustainability of tomato production in Iraq.
