Kerb Weather Data – Report 2 – week ending 28 October 2016

Kerb® Weather Data gives timing advice for application of Kerb Flo 500 and ASTROKerb® to oilseed rape.

Soil temperatures (at 30 cms) in Yorkshire are now sufficiently low for applications to be considered. The decision to spray now or wait should be based on local conditions, including the realistic chances of being able to travel, consideration of potential risk to watercourses and priority of spraying grassweeds in cereals. Consult VI for advice on protecting water-courses. In Scotland, soil temperatures are still marginal for the most effective results on ryegrass and brome.

Over other oilseed rape growing areas it’s still too warm for outstanding results to be achieved with Kerb® Flo 500 for blackgrass control.

For optimal blackgrass control Dow AgroSciences recommend Kerb Flo 500 and ASTROKerb  applications are made when soil temperatures have got down to 10°C and falling, and there is sufficient soil moisture in the soil for grassweed uptake.

More Kerb Weather Data will be supplied as the season progresses.

Kerb Weather Data – First Report – week ending 14th October 2016

Welcome to the first edition for this autumn giving timing advice for application to oilseed rape.

Soil temperatures (at 30 cms) in the oilseed rape growing areas are around 11°C – 14°C, too warm for outstanding results to be achieved with Kerb® Flo 500 for blackgrass control. Soils are also dry in many areas.

Please note a 30 cms soil temperature reading is less variable than the more commonly used 10 cm reading.

For optimal blackgrass control Dow AgroSciences recommend Kerb Flo 500 and ASTROKerb® applications are made when soil temperatures have got down to 10°C and falling, and there is sufficient soil moisture in the soil for grassweed uptake. Both these criteria are rarely met before November.

More Kerb Weather Data will be supplied as the season progresses.
