Rosy apple aphid: Prevent infestation using flower strips (Biofruitnet Practice Abstract)

Summary in the original language of the document

Reduction of the damage by pests, often below the economic damage threshold. Moreover, it supports bees (wild and honeybees) feeding and increases the success of pollination of the fruit flowers.
Practical recommendation: 1) Establish flower strips in the alleyways or areas besides the orchard. 2) Leave corners of the orchards untouched to allow the growth of wild plants (weeds). 3) Do not sow the flower strips in the tree row: this helps avoid water and nutrients competition and risks associated with frost damage during flowering and rodents. 4) A perfect seedbed is needed for the establishment of successful flower strips. Sow in August/September or April/May. After sowing, roll to ensure good contact between seed and soil. 5) Use a seed mixture with different species. Some species will grow better than others depending on soil characteristics. 6) Mix seeds with sand or vermiculite and use wild resident species produced locally, 1-4 g. seed per m2. 7) Avoid grass or other dominant species like Chicory (Cichorium intybus). 8) In the first year, cut the strip back to a plant height of 30-40 cm after 1-2 months. A second cut may be necessary 6-8 weeks later. 9) In the following years, the strips must be cut for mulching 3-4 times per year. Remove the cuts 2-3 days later.
