Is pesticide-free production a viable option

Consumer and environmental pressures continue to influence agrochemical usage. Farmers and growers are increasingly using ICM approaches for pest and disease control.

Economic pressures brought about by movement to world market prices are forcing farmers, growers and their advisers to be more discriminating in their use of inputs. Increased scientific understanding of pest and disease control requirements should enable risks to be identified and control measures to be targeted efficiently. Organic production is increasing in response to consumer demand. Would pesticide-free produce have strong appeal to consumer and where can it be achieved profitably?

There is an increasing world population to be fed. What forms of production and pesticide use will be required to feed the world in future? The issues surrounding pesticide-free production will be debated.
