Increasing resistance to established fungicides has stimulated the search for novel fungicides with new modes of action. Environmental concerns now also demand that these have low environmental impact and toxicity. Fungicidal Activity discusses new approaches to fungicide development including biological control and genetic engineering, and takes a global view of the future of fungicidal development. Fungicidal Activity is a volume in the Wiley Series in Agrochemicals and Plant Protection. This series brings together current scientific and regulatory knowledge and perspectives on all aspects of the use of chemicals and biotechnology in agriculture.
