Yes, organic farmers sometimes use pesticides. However, there are only 20 pesticides that they can use (as opposed to the hundreds used on conventional farms) and all of them are derived from natural ingredients. This means that they tend to be much less harmful to human and environmental health than synthetic pesticides that are used in conventional farming. Most organic farmers also use Integrated Pest Management to control pests and diseases – a system which works with nature and not against it – which means that they are using pesticides much less regularly, and do not rely on them.
