Extensive use of biological control agents in greenhouses

In 2012, biological control agents were applied to 90 per cent of the greenhouse area of edible crops, while chemical pesticides were used on 44 per cent of the area. Within ornamental plants, the corresponding shares were 32 per cent and 82 per cent respectively.

Most vegetables are treated with biological agents

Examples of biological control agents are macro organisms such as insects and micro organisms like fungi and bacteria. For cucumbers, tomatoes and lettuce, the share of crop areas treated with biological control agents was 99, 86 and 81 per cent respectively. Within ornamental plants, the average share was 32 per cent. Some areas are treated with both biological control agents and chemical pesticides.

Frequent use of chemical growth regulators in flowers

As a whole, growth regulators accounted for about half of the gross area treated with chemical pesticides. Growth regulators are mainly used in flowering potted plants. In edible crops, fungicides accounted for almost 57 per cent and insecticides for 43 per cent of the gross pesticide treated area. Insecticides were most widespread on tomatoes and lettuce, while fungicides dominated on cucumbers.
