Directions for use
Application

- Apply on infested leaves
- For hotspot treatments, apply Chrysopa directly in the heavily affected areas
- The product can be applied on the rock wool slabs, on leaves, via Dibox application boxes or distributed by Air(o)bug
Dosage
The dosage of Chrysopa depends on climate, crop and pest density and should always be adjusted to the particular situation. Start introduction as soon as the first pests are detected in the crop. Introduction rates typically range from 2-20 per m2/release. Releases should be made in infested areas only and repeated at weekly intervals until control is achieved. Consult a Koppert advisor or a recognized distributor of Koppert products for advice on the best strategy for your situation.
