Biological control of viruses of field vegetables. - HH1831SFV

Description
Insect and fungally transmitted viruses severly reduce the quality and hence marketable yield of many hortcultural crops. In most cases the quality of produce is vitally important to the growers, retailers and consumers. There are no effective control measures although insecticides and fungicides are routinely used in the hope of reducing damage. earlier research has demonsrtated the efficacy of cross-protection for control of an aphid-transmitted virus and the potential of soil-borne inoculants for the control of a fungus-transmitted virus. This programme seeks to develop a generic strategy for the selection and development of mild strains of plant viruses for biological control by cross-protection, and to develop strategies for determining the optimum deployment of soil-borne microbial inoculants against soil-borne obligate fungal pathogens infecting plant roots. the programme addresses policy objectives of reducing losses, improving quality, acceptability and availability of produce through developing sustainable and economically viable control measures. The knowledge gained will underpin the deployment of biological control agents and provide valuable information which subsequently may be needed for registration. Some aspects will feed through HDC-funded projects to provide growers with products and techniques for non-chemical control of virus diseases of field vegetables.
Objective
This project seeks to develop a generic strategy for the selection and development of mild strains of plant viruses for biological control by cross-protection, and to develop strategies for determining the optimal deployment of soil-borne microbial inoculants against soil-borne obligate fundal pathogens infecting plant roots.
