Extensive use of biological control agents

In 2008, biological control agents were applied on 81 per cent of the greenhouse area of edible crops, while 27 per cent of the area was treated with chemical pesticides. Within ornamental crops, the corresponding shares were 37 per cent and 61 per cent respectively.

Examples of biological control agents are macro organisms like insects and microorganisms like fungi and bacteria. In cucumbers, tomatoes and lettuce, the share of crop areas treated with biological control agents were 94, 74 and 67 per cent respectively. Within ornamental crops, the decorative plant area had the highest share with 73 per cent, while the lowest share was found on bedding plants with 18 per cent. Some areas are treated with both biological control agents and chemical pesticides.

Growth regulators most used in chemical pesticides

As a whole, growth regulators accounted for almost two thirds of the gross area treated with chemical pesticides. Growth regulators are mainly used in flowering potted plants. In edible crops, fungicides accounted for almost 52 per cent and insecticides for 48 per cent of the accumulated pesticide treated area. Insecticides were most widespread on tomatoes and lettuce, while fungicides dominated on cucumbers.

Data sources

Statistics Norway conducted its first survey on pesticide usage on protected crops in greenhouses in 2009. The survey comprised the following crops: flowering potted plants, cut flowers, bedding plants, decorative plants, lettuce, herbs, tomatoes, cucumbers and berries.
