Volunteer bean control in winter cereals

Volunteer beans not only compete with the crop for light and nutrients, their presence in cereals can also cause problems for grassweed control as large, leafy bean plants can shade grassweeds and reduce control from contact graminicides. Autumn is the best time to control volunteer beans.

Volunteer bean control with Zypar™ or Spitfire®

Following the successful launch of Zypar (Arylex + florasulam) in spring 2017, this will be the first autumn that Zypar is available for autumn use. Arylex is highly active on legumes and gives significantly better control than florasulam alone. Zypar works in fluctuating temperatures to achieve rapid kill of volunteer beans, plus an extensive list of additional broad-leaved weeds including cranesbill.

For volunteer bean control with Zypar

  • Zypar 0.5 L/ha – Beans up to 8 true leaves (4 pairs)

Spitfire (fluroxypyr + florasulam) remains as the tried and tested product for the control of volunteer beans in the autumn. The combination of active ingredients is important: the fluroxypyr delivers rapid disruption to growth of the beans while the florasulam element ensures an effective kill, even in cold conditions. With its unique formulation, Spitfire delivers consistent, robust control of volunteers, whilst using a lower dose of florasulam than other formulations on the market leaving you with ALS flexibility in the spring. Also, it does not contain DFF, giving you flexibility with your autumn residual programme and following crop options.

Based on our trials work, recommendations for volunteer bean control are:

  • Spitfire 0.5 L/ha + adjuvant* – Beans at 4 true leaf (2 pairs)
  • Spitfire 0.75 L/ha + adjuvant* – Beans at 6 true leaf (3 pairs)
