Weed Control

When it comes to blackgrass and other grassweeds, the power of Kerb® Flo 500 (propyzamide) has stood the test of time. With no reports of blackgrass resistance, ASTROKerb® is a vital weapon to fight grassweeds.  ASTROKerb also provides enhanced  performance against certain broad-leaved weeds such as mayweed and poppy.

Both are best applied when soil temperatures have got down to 10°C at 30 cm and falling and there is sufficient moisture in the soil for plant uptake.  These conditions are rarely met before November. (Both products can be used up to January 31st).

To get more detailed information, starting in October,  sign up for our e-newsletter and full weather data to see whether conditions are correct for Kerb Flo 500 or ASTROKerb applications.

When broad-leaved weeds need to be controlled, the proven post-emergence herbicide Galera will control mayweeds, thistles and a range of other broad-leaved weeds in winter oilseed rape.


Stewardship

Water stewardship needs to be top of mind to both safeguard the environment and to protect Kerb Flo 500 and ASTROKerb from withdrawal. If you can travel, applications of Kerb Flo 500 or ASTROKerb must only be made after taking all necessary precautions to avoid contaminating surface waters. Kerb Flo 500 and ASTROKerb may be applied in frosty conditions but avoid application onto frozen ground where subsequent rainfall could result in run-off into watercourses. More information on water stewardship can be found on the Voluntary Initiative website.
