(Active substances: iodosulfuron-methyl-sodium, sulfonylurea)

Hussar gives you reliable control of rye-grasses, meadow-grasses and a range of broad-leaved weeds in winter wheat. It is one of the few products approved on spring barley for annual meadow-grass control.

Why Hussar?

At full dose Hussar controls a wide spectrum of broad-leaved weeds, as well as providing useful activity against cleavers and key grass-weeds such as rye-grass and meadow-grass. The timing flexibility of Hussar allows control of both broad-leaved weeds and grass-weeds in a single application.

Main advantages

• Flexible timing window for application from February 1^st to before GS 33 for winter wheat, rye and triticale and before GS 30 for spring barley
• Controls a wide range of broad-leaved weeds, grass-weeds and cleavers
• There are no restrictions on following cereal crops or sugar beet sown in the following spring
• Low dose, water-dispersible granular (WG) formulation

Getting the best from Hussar

The optimum timing for control of weeds is when most have emerged and are between two-leaf and mid-tillering in grass-weeds, or six-leaf in broad-leaved weeds. By treating at this early stage you reduce the weed competition and increase your yield potential. Hussar should be applied in warm weather when the soil is moist and weeds are actively growing.

Important things to remember

• Don’t apply Hussar as the sole means of rye-grass control in winter wheat in any one season
• Apply before GS 31 of rye-grass (ideally within GS 13-23)
• For rye-grass, do not use reduced rates, particularly where resistance is confirmed or suspected; application has been delayed past early tillering; or environmental conditions are not optimal
• The addition of an adjuvant is not essential but it may improve the effectiveness of Hussar. However, don’t use an adjuvant on spring barley
• Uptake of the active substance on the dry leaf takes place within two hours. Therefore, effectiveness is not affected by rainfall occurring two hours after application
• Don’t apply to crops undersown or due to be undersown with clover and alfalfa
• Don’t roll or harrow within one week of spraying
• Don’t spray crops under stress, suffering drought, waterlogged, grazing, lacking nutrients or if the soil is compacted
• Don’t tank-mix with fop/dim herbicides – apply in sequence.
• In rye-grass situations, don’t tank-mix with CTU

Hussar as part of a programme

For rye-grass, Hussar should only be used as part of a herbicide programme that also includes an effective autumn-applied residual herbicide such as Liberator (flufenacet and diflufenican).
