How to get the best out of Belkar herbicide and planning your propyzamide (Kerb Flo 500 and AstroKerb) applications this autumn
|
Drought, slugs, CSFB, late drilling? We know you are under pressure. For others, if your oilseed rape crop is motoring along like Rob Fox’s from Woodhall Estate, it will soon be time to assess the weed pressure.
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.
Arylex™ active has been formulated with picloram to create Belkar. The product 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:
|
At two true leaves, an application at 0.25l/ha will take out the weeds which have germinated alongside the crop and, in some circumstances, that will be enough broad-leaved control before an application of Astrokerb® (propyzamide + aminopyralid) or Kerb® Flo 500 (propyzamide) where grassweeds are a problem.
In high weed pressure situations where germination of another flush of weeds occurs, growers have the option to make a second 0.25l/ha spray. This is usually two to four weeks after the first application.
Depending on workloads, growers can wait until six true leaves of the crop and all the weeds have flushed – after 15 September – to tackle bigger weeds at a rate of 0.5l/ha which will take care of the weeds going into the autumn.

Autumn nitrogen stabiliser 'Instinct' available for arable crops
|
New trials data shows that arable crops can benefit from autumn applications of the innovative nitrogen stabiliser product Instinct®, which keeps more nitrogen in the soil for longer. In oilseed rape, yield responses of up to 7% were observed when Instinct was used with slurry in the autumn.
Category Manager Colin Bowers said: “A crop reaching its yield potential is underpinned by successful establishment. In cereals and oilseed rape, we have seen evidence of improved autumn establishment from using Instinct in the autumn, especially when used in conjunction with slurry and digestate. Our internal development trials showed yield responses of up to 7% and improve spring vigour in oilseed rape when Instinct is used with slurry in the autumn”.
The product should be applied at a rate of 1.7L/ha, as close to the application of the source of nitrogen as possible – ideally within a couple of days either side, if not applied with the slurry or digestate. Instinct can be applied to a seed bed and incorporated or simply sprayed on as a surface application. “When applied to the soil surface, the ideal situation is for there to be at least 12 mm of rain during the 10 days following application in order for the product to be washed into the soil,” Colin added.
The product is in stock and available to cereal and oilseed rape growers across the UK and Ireland. Find out more about Instinct here.
