Winter Wheat Update – early July 2020

Pests

Check the ears of wheat up to GS73 for aphids. If two-thirds of heads are infested then consider an aphicide. Bear in mind that grain aphids may well be resistant to pyrethroid aphicides, so consider using a flonicamid.  Seek specific pesticide guidance from your local agricultural advisor or agronomist.
