Throughout New Zealand's history, primary industries have been the mainstay of this country's economy. Despite our isolation from major world markets, New Zealand is often able to demand a price premium for its products based on its clean green image and high quality produce. Customer demands for blemish-free produce have necessitated increased use of synthetic pesticides, but downsides to their use include adverse environmental impacts and human health concerns. Moreover, the presence of pesticide residues in produce are increasingly being used as non-tariff trade barriers. These factors drive the need to find alternative forms of pest control.
Plant defence is an essential tool for helping to control pests, but there are currently many challenges to using it to full potential. In 2011, the New Zealand Plant Protection Society organised a symposium to address ways in which plant defence can be used and the challenges around using it. The eleven papers contained in this publication give local and international examples of how plant defence has been used to overcome insect, disease and weed pests.
Topics covered include: plant defence cross talk; use of elicitors; manipulation of volatiles; use of symbiotic endophytes and mycorrhizal fungi; and allelopathy. Limitations of plant defence are discussed along with suggestions to mitigate problems. This book will serve as a thought-provoking treatise on a topic that is becoming increasingly important in global horticultural and agricultural husbandry.
