Unseasonal heat wave brings first reports of blossom midge

24 May 2010

Temperatures in the high twenties have encouraged crop and weed growth after a long cool spring.

Many oilseed rape crops are setting pods as the flowering phase passes. Lack of rain is the new problem, however, with many crops still waiting to take up significant amounts of applied fertilisers.
