Product details

Mode of action

Released parasitic wasps will parasitise the wheat aphids (Sitobion avenae) present on the cereal planyd and form a large population of parasitic wasps on the cereal plants. The aphid infestation level remains low due to the continuous presence of large quantities of parasitic wasps, searching actively for aphids in the crop.

Product specifications

Pack size	1 box of cereal plants with approximately 500 wheat aphids.
Presentation	Plastic box.
Developmental stage	All stages.
Carrier	Winter wheat.

Product handling

Application

Open the box immediately after receipt
Fill a hanging basket of 20 cm diameter with a piece of wetted rock wool
Take the tussock of cereal plants from the box and place it on the rock wool in the basket
Place the basket in direct light, preferably in a spot where it can remain for 10-12 weeks
Fit a dripper to the tussock for continuous supply of water and nutrients, arrange proper drainage for any excess water
Move the dripper from tussock to rock wool when roots start to grow
Best results are obtained when the banker plants hang above the crop
To prevent the crop from honeydew contamination, secreted by the aphids, a large plastic bowl can be placed under the hanging basket
If aphids are found in the crop before the banker plants produce parasitic wasps, apply Ervipar
Regularly add new tussocks
Start introductions of Aphidend as soon as hyperparasitoids occur in banker plants or crop

Dosage

Use 5-15 Ervibank per hectare. Consult a Koppert advisor or a recognized distributor of Koppert products for advice on the best strategy for your situation.

Environmental conditions

Ervibank is effective at temperatures up to approximately 30°C/86°F.

Side Effects

Aphids on banker plants are extremely susceptible to insecticides. Remove the banker plants from the greenhouse for at least 24 hours when fogging/spraying an insecticide. If the insecticide is applied via the drip system, remove the drippers from the banker plants for approximately 24 hours. In these cases it may be necessary to switch to an alternative way of irrigation temporarily.

Notes

Wheat aphids can only live and reproduce on monocotyledons. As most cultivated crops in greenhouses are dicotyledons they are not attacked.

Storage time after receipt

Apply as soon as possible after receipt. If necessary, the product can be stored for 1-2 days.

Storage temperature

5-8°C/41-47°F.
