Cerone is the plant growth regulator (PGR) that we would recommend as a second spray in a programme to ensure maximum stem strength and to help prevent lodging. Cerone is consistently the best PGR to use at T2 in winter wheat and both winter and spring barley.

We have designed Upgrade as a flexible treatment that can be used either early or late to reduce lodging. It means that decisions can be made at any stage and it can be used in sequence with other plant growth regulators.
