About Manhattan

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.com/uk/tools-and-advice/tank-mixes.html for further information on compatibilities and ALS joint applications.

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.
