Banker plants with either Sitobion avenae or Rhopalosiphum padi are from 2020 delivered in a biodegradable pot and closed with fleece. the plants are used together with either Aphidius ervi og A.colemani to create a “bank” of parasitoids released continuously in the crop.
Place banker plants in the crop, can be placed with good results in a bigger pot with peat, and add some parasitoids the following week. renew banker plants after 8 weeks.
