Always use the biopower adjuvant.
Hamlet is a contact acting herbicide so the spray needs to land and stay on the target leaf; a fine-medium spray is the best way to achieve this. As Hamlet is such a crucial spray for the success of the crop, double check sprayer set up such as GPS calibration, boom height and blocked nozzles – any problem will translate into reduced control.
All applications should be made with a maximum forward speed of 12km / hour to maximise coverage and minimise drift.
Mix partners for Hamlet
Hamlet already has a strong package of contact action and residual control but there are options for growers concerned about late germinating weeds. The addition of a flufenacet product to complement the diflufenican is the best way to boost residual control. For full guidance on other products refer to the tank-mix sheet.
Hamlet’s active substances are not newcomers for weed control in wheat so the bad news is that there is already resistance lurking in black-grass and other weed populations. The good news is that control isn’t likely to fall away due to a rapid emergence of a new type of resistance so Hamlet will continue to provide control but it is still sensible to take steps to protect it.
Use Hamlet as part of a diverse control programme mixing chemical and cultural techniques. Weed control in crop is always a challenge so reduce weed populations as much as possible before crops go in the ground. If black-grass populations are very high, consider using spring crops to reduce numbers before bringing winter wheat back into the rotation.
Once you’ve made the decision to use Hamlet, apply it at the right time and apply it well to maximise efficacy and minimise resistance risks.
Using Hamlet also helps protect other actives in your control programme. Any survivor of a pre-em may carry a resistance risk so eliminating as many survivors as possible with Hamlet is a sound decision.
