Winter wheat in February

Manhattan

Herbicide

NEW FOR SPRING 2025

Manhattan is a 3-way combination of pyroxsulam, florasulam and Arylex™, a post-emergence herbicide, providing broad spectrum grass and broad-leaved weed control in winter wheat, winter rye, winter triticale and winter spelt. 

It offers outstanding control of ryegrass, brome, wild oats and loose silky-bent, as well as an extensive spectrum of key difficult broad-leaved weeds, including cleavers, poppy, speedwell, mayweed, chickweed, fumitory and umbellifer speces. 

About Manhattan

Benefits

  • Excellent broad spectrum grass weed control, including brome, ryegrass, wild oats and loose silky-bent. 
  • Controls a range of difficult broad-leaved weeds, including cleavers, poppy, speedwells, mayweeds, chickweed, fumitory, cranesbill and umbellifer species e.g. bur chervil. 
  • Can be used in joint application with a wide range of ALS-inhibitor broad-leaved weed herbicide products. 
  • Physically compatible with a wide range of herbicides, insecticides and trace elements making it an excellent tank mix partner. 
  • Refer to https://www.corteva.co.uk/tools-and-advice/tank-mixes.html for further information on compatibilities and ALS joint applications.

Best Use Advice

  • Apply Manhattan at 100 g/ha with a supported adjuvant (95% w/w oil, rapeseed fatty acid): 
    • (Actirob B, Phase II, Intracrop Rigger, Spraymate, Super Rapeeze & Toil)​ 
  • Brome control is best achieved from GS11-GS24 (optimum being 1-3 leaves). 
  • Ryegrass and wild oat control is best achieved from GS11-GS29 (optimum being 1-3 leaves). 
  • Ensure Manhattan is applied during periods of active growth and do not apply to crops or weeds under stress. 
  • Manhattan can sometimes induce slight transient crop yellowing; this has no impact on yield. 
  • To avoid subsequent injury to crops (other than winter wheat, spelt, rye and triticale), immediately after spraying Manhattan all spraying equipment must be thoroughly cleaned both inside and out using a proprietary tank cleaner such as All Clear Extra spray cleaner at 0.5% v/v.
