Studies on the economic impact of Pepino mosaic virus - HH3226SPC

The aim of this research is to further understand the economic impact of Pepino mosaic virus (PepMV) on tomato crops. It will involve the establishment of a near-commercial, replicated trial, which will permit a detailed comparison to be made between infected and uninfected crops, with respect to both the yield and quality of fruit. It will also result in increased understanding of how the virus affects plant development and how timing of infection impacts on the economic significance of the virus. An additional years data will enable the comparison between years and this will contribute to an understanding of PepMV and would enable development of disease management strategies. Knowledge generated in the project will be transferred to the industry via the Tomato Growers Association and the industry press. It is also the intention to develop a HortLINK proposal in partnership with the TGA and HDC to address future research priorities on the effects of PepMV on fruit quality. This work relates to DEFRA’s policy objectives of promoting a modern, adaptable, diverse and sustainable farming industry as well as a competitive food supply chain which is responsive to the needs of consumers. This will be achieved by understanding the factors involved in PepMV disease resulting in better disease management.
1. To determine the effect of infection with PepMV at two growth stages (during propagation and when plants reach the wire) on yield and quality of a full season crop of hydroponic tomatoes grown under near commercial conditions.

2. Transfer knowledge generated in the project to the industry via the Tomato Growers Association and attempt to develop a HortLINK proposal in partnership with them to address future research priorities.

Infection of the uninfected control crops in this replicated trial would have serious implications on being able to achieve the objectives of this work. Stringent measures will be taken to prevent accidental contamination. This will involve following the standard operating procedures developed in the previous project and continual monitoring using diagnostic kits and ELISA.
