The perfect combination for Couch control:
Monitor in spring, Roundup® pre‐harvest or on stubble EMEA
MONITOR® is suppressing Couch in
crop, safes the yield ,
the yield advantage pays for more than
the Roundup treatment = Roundup
treatment is „Free Of Charge“
Significant advantage: as couch still has
green leafs below canopy Roundup can
be used on stubbles right after harvest

17. Acetochlor: benefits of pre‐ cropprotection
EMEA
emergence weed control
“Start clean, stay clean” concept
protection of the crop against weed competition from the very early stages
Trend to earlier sowing means plants grow more slowly in the early
stages
Pre‐em herbicide limits early weed competition
Acetochlor facilitates the benefits of earlier sowing: more water
efficiency, and increased yield – key elements for higher sustainability
in corn production.
Key to integrated weed management
Foundation of a weed control programme
Sequences/mixtures with other pre‐em and post‐em herbicides
Weed resistance management: no resistant weeds in Europe known

23. cropprotection
Acetochlor: more advantages EMEA
Performance under dry conditions
Acetochlor is rated among the best pre‐em herbicides in dry conditions (ARVALIS*)
Weed resistance management
Limited resistance despite widespread use around the world since the 1970’s
some weeds cannot be effectively controlled by other pre‐emergence herbicides, particularly
sulfonyl ureas
Management of resistance in grasses
Flexible dose rate
Standard rate – season long weed control
Reduced rate – sequential/tank mix with pre or post em herbicides
Crop selectivity
Excellent selectivity in maize (safener)
all types of maize : grain and silage, sweet maize, and inbreds
No “carry‐over” = no restriction on subsequent crops
Registered in cotton in Greece
