ASTROKerb & KERB Flo 500 with large crop canopies

removal-of-canopyWork done last year in the UK has answered a frequently asked question from advisors “ is it OK to spray Kerb Flo 500 with a rape canopy that is intact?”

Kerb Weather Data – Final Report – Week ending 18th November 2016

Kerb® Weather Data gives timing advice for application of Kerb Flo 500 and ASTROKerb® to oilseed rape. (For beans, Kerb Flo 500 must be applied within 7 days of drilling but before crop emergence).

With cooler conditions and moist soils consider application to oilseed rape when conditions allow. Consider potential risk to watercourses. Consult VI for advice.

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.

Kerb Weather Data – Report 4 – week ending 11th November

Kerb® Weather Data gives timing advice for application of Kerb Flo 500 and ASTROKerb® to oilseed rape. (For beans, Kerb Flo 500 must be applied within 7 days of drilling but before crop emergence).

With falling temperatures and recent rain/snow, consider application to oilseed rape when conditions allow. The decision to spray now or wait should be based on local conditions, including the realistic chances of being able to travel and consideration of potential risk to watercourses. Consult VI for advice on protecting water-courses.

Winter beans – great opportunity to control blackgrass

beans-and-wheatWinter oilseed rape is still the most widely grown break crop in the UK, but some growers have abandoned this crop as yields have been variable and input costs regarded as high. Nevertheless it is still the third most widely grown crop. The obvious break crop to take its place is winter beans and the negative view on rape plus the Three Crop ruling is seeing an expansion of this crop.

Kerb Weather Data – Report 3 – week ending 4th November 2016

Kerb® Weather Data gives timing advice for application of Kerb Flo 500 and ASTROKerb® to oilseed rape. (For beans, Kerb Flo 500 must be applied within 7 days of drilling but before crop emergence).

Over most of the UK, temperatures remain too warm for outstanding results to be achieved with Kerb® Flo 500 for blackgrass control in rape. In many areas it’s also dry.

Soil temperatures (at 30 cms) in Yorkshire are sufficiently low for applications to be considered.
