Belkar allows you to invest in weed control once your crop has established and weeds are present.

The broad-spectrum post-emergence herbicide is highly effective on key weeds such as cleavers, cranesbill, poppy, shepherd’s purse and fumitory.

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:

  • When the crop is two-four 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, later in the season.
  • In high weed pressure situations where 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 after the 15th of September when the crop is at least six true leaves and all the weeds have flushed to tackle bigger weeds at a rate of 0.5l/ha. This will take care of the weeds going into the autumn.
