Leaf miners (Lyriomyza spp.).
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.
It is not possible to see on the outside if the leaf miner larvae or pupae are parasitized.
|Pack size||500 adults.|
|Presentation||100 ml bottle.|
Directions for use
- Release parasitic wasps between the leaves of the crop in the morning or in the evening
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.
Minusa is more effective than Miglyphus at lower temperatures (<20°C/68°F). When temperatures rise Minusa can be supported by Miglyphus.
Can be combined with Miglyphus.
