The dosage of Delphibug depends on climate, crop and whitefly density and should always be adjusted to the particular situation. Start introduction as soon as a whitefly hotspot is detected in the crop. Introduction rates typically range from 1-4 per m2/release. Releases should be repeated at least 3 times at weekly intervals, or until the pest is controlled. Consult a Koppert advisor or a recognized distributor of Koppert products for advice on the best strategy for your situation.
