The Flower Power System® is a cultivation method for oilseed rape designed to reduce the need of sprayings against insects during flowering by means of a white flowering (‘white’) variety as main crop and a yellow flowering (‘yellow’) variety as trap crop.
The principle is shown on the pictures to the left. 6 ha white spring oilseed rape is surrounded by 10 m frame of a yellow flowering variety. 5 % of the yellow variety is mixed into the white main crop as a second defence line. In this field insect sprayings were not needed during flowering, only once in the bud stage against pollen beetles.
The Flower Power System® stands for methods to reduce the needs of insecticides in rapeseed by the use of different flower colors and different earliness of flowering.
The system does not help before flowering (of some of the plants).
In some years the amount of insects are very high and spraying is necessary. But a focused treatment of the yellow frame might be enough.
