Immediately before sowing, the seeds of both cultivars were treated with the insecticide Standak ® Top (200 ml. per ha) and were inoculated with Biomax (300 ml. per 100 kg seed).

However, the discussion of weed control in this text analysis is guided on a 20% probability, due to higher discriminatory power and accuracy in significant differences found.
  • Onduty® provided excellent residual control, allowing reduction between 85 and 90% in the emergence of new plants within the crop cycle. This lower density of plants in treatments with Onduty® leads to a much more comfortable and efficient post-emergence application, what affects positively the final control.
