Introducing Monolith

Darren Adkins & Jack Hill 29th & 30th November 2017

• Monolith is our new specialist grass-weed herbicide and is the evolution of

Atlantis WG in the spring…

Monolith - what is the product concept?

Atlantis WG 12 g Meso + 2.4g iodo @ 0.4 Kg/ha

• 22.5g propoxycarbazone

& 3g mesosulfuron + 2.4g iodosulfuron

• Iodo is predominantly BLW

acting, with some grass activity

• Mesosulfuron is the major grass-weed

active in Atlantis

• Propoxycarbazone - the AI in Attribut – is

also grass-weed acting

How Monolith fits into an integrated weed control program in winter wheat

AUG SEP OCT NOV DEC JAN FEB MAR APR MAY It’s essential to use all cultural controls available to reduce weed burden Delay drilling until after the major flush of black-grass Pre- emergence treatments like Liberator remain the bedrock of chemical control The cut off for Monolith is pre- GS33 T1 is the latest time

• f application

Monolith can be used from 1st February It’s important to target weeds which are as small as possible Monolith should be applied as soon as conditions are suitable after February 1st The key application window will be during March

Monolith on black-grass

Average of 10% better black-grass control than Atlantis WG

Source: 19 replicated trials in 2012-2017. Average population in untreated = 297 heads/m2

0% 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% Atlantis WG 0.4 kg/ha + Biopower 1.0 L/ha Monolith WG 0.33 kg/ha + Biopower 1.0 L/ha % control based on head counts

What does 10% better black-grass control mean to a farmer?

No post-em applied 297 heads/ m2 remained

101 heads/ m2 remained 2.5 t/ Ha yield benefit vs. UT

73 heads/ m2 remained 0.3 t/ Ha yield benefit vs. Atlantis WG

0.3 t = £42*

Take the example of the 19 trials shown previously…

What does 10% better black-grass control mean to a farmer?

= = 10% more black-grass control Fewer heads at the end of the season Fewer seeds returned to the seedbank Untreated 297 heads/ m2 remained 101 heads/ m2 remained 73 heads/ m2 remained 28 heads/ m2 fewer remained when Monolith was used rather than Atlantis WG

OR 280,000 heads per Ha This means that using Monolith rather than Atlantis WG resulted in 28,000,000 fewer seeds going back into the seed bank* That’s more than the combined population of London, New York, Paris, LA & Sydney!
