OSR crops winning the seasonal race against pollen beetle

The majority of weather stations on the Bayer Pollen Beetle Predictor tool are still showing only 20 to 30 per cent migration as many oilseed rape (OSR) crops begin to flower.

Regional exceptions include the South West and Scotland where migration is around 15 per cent, and the North West, where migration is around 36 per cent.

 

Against the backdrop of slow migration, Dr Steve Ellis of ADAS reports that most crops have reached yellow bud and some have flowers open. “This could be all it takes to see crops into flowering and past the damage susceptible phase by the beginning of April,” he says.

 

The ‘new migration’ map is mostly showing moderate migration conditions, with some weather stations on the western side of the country having good migration conditions.

According to BBC Weather, sunshine and showers is the theme of the week ahead and the forecast includes temperatures around the mid-teens.

 

Dr Ellis says: “This outlook should allow migration to move forward, but probably too slowly to cause concern for crops already at yellow bud. However, all growers – particularly those with backward crops – should keep checking the pollen beetle predictor until their crops are flowering in earnest.”
