Aphids
(Summer)
- Apply an insecticide listed for this insect under Early
Spring. Some products have limited numbers of applications per year.
Japanese beetles (Summer)
- Comments: Adult beetles can severely defoliate hazelnut
orchards beginning in late spring and can continue well into summer.
There are currently no insecticides registered for control of adult
Japanese beetles on hazelnut. Clean cultivation may help reduce larvae
populations in the orchard soil, however new adults usually fly in from
other areas.
Filbert
worm (Summer)
- Comments: Filbert worm is native to Ontario on wild
hazelnuts and may become a problem in commercial orchards. Monitor samples
of nuts near harvest for signs of internal feeding by larvae.
Wood-boring
insects (Summer)
- Comments: Monitor main branches and trunk for small
holes and sawdust on the ground near the trunk. Hazelnuts are host to
several wood-boring insect pests that are common to commercial fruit
orchards and forest tree and shrub species. There are no insecticides
registered for wood-boring insects on hazelnut.
Precautions
Read the label and follow all safety precautions.
Consult the product label for suggested water volumes. Otherwise, use
enough water to ensure thorough spray coverage. Where the product rate
is listed in amount per 1,000 L and if a water volume is not provided
on the label, use enough water to wet the foliage to the near drip point.
For preharvest interval, re-entry period, maximum number of applications
and chemical group, see Table
