The last of nine programmes on the science behind gardening presented by Alan Hibbert To Spray or Not to Spray?
Pesticides are getting a bad press these days. Gardeners don't want to eat vegetables covered in chemicals and the pests are becoming resistant anyway. But new methods are evolving - ' organic ' gardening, biological control with natural predators and the use of pheromones.
Film editor JOHN KEENAN Produced by RON BLOOMFIELD and BRYN BROOKS
