Koppert Aphidend (Aphid Control)

• Adult gall midges emerge from the pupae and deposit their eggs in the aphid colonies. After emerging from the eggs the larvae consume the aphids. Aphids are consumed entirely, only skin remains.

How to use Aphidend?

Application

• Open the bottle in the greenhouse
• Place the bottle directly on the soil or rockwool slabs or hang it in-between the plants
• Do not scatter the contents
• Once emerged, the adult gall-midges will leave the bottle and spread

Dosage

• The dosage of Aphidend depends on climate, crop and aphid density and should always be adjusted to the particular situation. Start introduction as soon as the first aphids are detected in the crop. Introduction rates typically range from 1-10 per m2/release. Releases should be repeated at weekly intervals until control is achieved. 

Best working conditions for Aphidend

• Most effective between 20 and 30°C (68 and 86°F), effectivity decreases significantly at higher temperatures. As gall-midges are active at night, it is crucial to keep the night temperature above 12°C/61°F, to ensure optimal conditions for oviposition. Apply Aphidend in an environment with a high relative humidity (> 70%) to get the best results.

Combined use

• High densities of generalist predatory mites, especially Amblyseius swirskii, can be detrimental to Aphidend as the predatory mites feed on the eggs of Aphidoletes aphidimyza. Can be combined with aphid parasitoids.
