The claim means Dockstar can now be used at a lower rate (2 litres per ha) in a tank-mix with Baton herbicide at 2 kg per ha.
 

Recommended for spring applications only, this mix provides the same efficacy against docks as Dockstar applied alone at 4 litres per ha, with less pasture shock. It also gives control of the wide range of pasture weeds on the Baton label.
 

The timing of use around pasture management and grazing intervals is the same as for Dockstar alone.
 

“Docks, as most know, are a real issue for farmers in many parts of New Zealand,” says Nufarm technical specialist Paul
Addison.
 

“They’re persistent and tough to eradicate once they take hold. Few farmers can afford to sacrifice good grazing in the best of seasons, and when the pressure is on in terms of product prices, keeping paddocks productive and free of weeds is more important than ever.”
 

Docks (Rumex sp.) are a prevalent pasture weed throughout NZ. The broadleaf dock is a perennial plant with a large tap-root which  can quickly out-compete surrounding pasture.
 

Broad flat leaves (up to 35 cm long by 15 cm wide) make the weed particularly effective at reducing pasture quality.
 

Dock foliage contains tannins, and while sheep will generally eat the leaves, cows find them unpalatable, so this weed can become problematic on dairy farms.
 

A single plant can produce up to 40,000 seeds every year, and these can remain viable for several years leading to the buildup of a heavy seed burden in the soil over time. Docks spread mainly by seed but plants also regenerate readily from root fragments.
 

Docks are tolerant of poorly drained soil and will often be found in low-lying areas of a paddock. Flowering typically occurs from November to April and control is best achieved when the plant is actively growing and in full leaf stage.
 

“Dockstar, and now Dockstar with Baton, give farmers more tools to use in keeping their pastures productive and free of weeds,” Paul Addison says.
 

Trials show Dockstar alone is just as effective at controlling docks as other options on the market (i.e. thifensulfuron).
 

Paul Addison says control is relatively slow with peak control occurring two to three months following treatment. Very large, well-established docks may require a follow up application.
 

Dockstar is an easy-to-use, soluble liquid formulation presented in 20 litre packs with a handy dual pourer.
