Octavian Met

Octavian Met delivers effective weed control in winter barley and winter wheat. Available to use at pre-emergence and as a residual top up it provides a good option for black-grass, brome and broad-leaved weed control.

It is a three-way coformulation of metribuzin, flufenacet and diflufenican. The addition of metribuzin to flufenacet provides improved grass weed and broad-leaved weed control compared to Liberator.

The metribuzin component is primarily root acting but also has some activity against shoot which means it is a strong candidate to use for top up applications. The addition of metribuzin provides up to 10% more black-grass control at the full rate compared to straight Liberator.

Octavian Met is a simple, way to apply three effective actives for weed control throughout the autumn. Using a range of actives in the autumn programme boosts weed control and manages resistance risk. Octavian Met delivers an entirely new active for UK cereals – metribuzin – as well as the reliable performers flufenacet and diflufenican as found in Liberator.

For pre-emergence applications, apply the full 1l/ha rate within 48 hours of drilling to get the best results. However, results from trials show that even if the application is delayed until peri-emergence you can still expect good levels of control. For all applications, ensure the seedbed is in good condition and free of clods and trash for optimum performance. The shoot activity means it can give some control of established weeds as well as prevent further germination so it is also a good option as a ‘top-up’ spray at the 0.5 l/ha rate. It can be used until growth stage 25.

Including additional actives to the autumn herbicide programme is a proven way to boost black-grass control. Octavian Met delivers an entirely new active for UK cereals – metribuzin – as well as the reliable performers flufenacet and diflufenican as found in Liberator. Octavian Met is a flexible product suitable for pre-em, peri-em and early post-em applications.
