Sugar Beet

Sugar beet is one of then most responsive crops to good agronomy. And within its agronomy, crop protection is a major contributor to yield and profit. We at Bayer are focused on providing solutions to all the crop protection issues you face in growing sugar beet, be it weed competition, pest damage or disease threats.

Rapid establishment is the first step to beating virus yellows

The withdrawal of neonicotinoid seed treatments means crops are once again at risk from a complex of viruses that can lead to yield losses of up to 47%. With nothing as nearly as reliable available to protect crops, growers will have to develop a strategy that considers everything from establishment to weed control to the strategic use of a single insecticide if crops are to make it through to about 12 to 13 weeks when the plant’s natural defences start to provide protection.

Advisory information

Alternating insecticides with different modes of action is a recognised anti-resistance strategy and Biscaya should be used in alternation with insecticides of a different mode of action, giving consideration to the overall treatment programme on the crop against a range of pests.

Aphid Thresholds for Biscaya Application

  • If numbers exceed the threshold for treatment of one green wingless aphid per four plants up until 12 leaf-stage (or one green wingless aphid per plant after this growth stage) then treatment will be justified
  • Repeat treatments will only be justified if the threshold is exceeded again at the appropriate growth stage
  • Growers are encouraged to follow BBRO Advisory Bulletin updates and visit the aphid survey 2019 regularly for updates on aphid numbers and their virus levels.



When and how to apply

  • Before use

    Always shake the container well by repeated inversion. This is to ensure the two phases of the oil dispersion (OD) formulation are combined in a homogenous mix.
