Five things to consider when growing crops this October in the south
Oilseed rape crops drilled in early to mid-August have grown away fast, helped by bits of rain. There has been some cabbage stem flea beetle activity, and some treatment with pyrethroids, although efficacy needs to be checked.
While earlier drillings have reached 6-8 true leaves, first half of September drillings are still emerging as reach the last week of September, and yet to get going. But there are no horror stories and growers are feeling optimistic.
Further west of Exeter, I get the feeling the winter cereal area will be down after the problems we’ve had keeping crops going through incredibly wet winters, and that spring barleys have outyielded winter barley.
Those growing malting barley have been drilling and some wheats have started going in too from mid-September, although agronomists have been trying to keep the brakes on.
