How it works

How it works

Mode of action

The adult female parasitic wasps of Dacnusa sibirica preferably lay their eggs inside first and second instars of the leaf miner larva. The parasitic wasps develop inside the leaf miner pupa. The adult wasp will emerge from the pupa.

Visual effect

It is not possible to see on the outside if the leaf miner larvae or pupae are parasitized.

Dosage

The dosage of Minusa depends on climate, crop and leaf miner density and should always be adjusted to the particular situation. Start introduction as soon as the first mines are visible in the crop. Introduction rates typically range from 0.25-0.5 per m2/release. Releases should be repeated at least 3 times at weekly intervals or until control is achieved. At higher temperatures (>25°C/77°F) and/or higher infestation rates it might be better to use Miglyphus. Consult a Koppert advisor or a recognized distributor of Koppert products for advice on the best strategy for your situation.
