Getting the best out of Belkar® herbicide and planning your propyzamide applications this autumn

With Belkar ^®, wait until your crop is established and then tackle the weeds that are visible. Belkar offers outstanding control of key weeds including cleavers, cranesbill, poppy, shepherd's purse and fumitory.

Belkar has a window of application from either 1 or 15 September (depending on the rate being used) through to 31 December and it works in warm and cool conditions (down to 2°C) making it the ideal autumn herbicide. There are three treatment options of Belkar which have performed best in trials. Read our latest Arable Update to find out more.

Corteva’s portfolio of oilseed rape herbicides offer flexible, reliable control across a wide spectrum of weeds and timings. They can fit into the programme based on the season and target weeds. Take a look at our topic sheet 'Herbicide programme options for oilseed rape.'

As we head towards applications of propyzamide, be sure to look at our new Propyzamide Knowledge Hub.

Capture nitrogen throughout the season

BlueN is classed as a foliar applied biostimulant, composed of an exclusive strain of naturally occurring endophytic bacteria, Methylobacterium symbioticum. M. symbioticum uses methanol given off by the plant during metabolic processes as an energy source to fix atmospheric nitrogen and convert it to ammonium inside the plant. Ammonium is used to make essential amino acids essential for plant growth.
