Only a registered Professional User using a registered sprayer is approved to apply pesticides. Sustainable Use Directiveįinally ensure you are cross compliant when using sprays. Regular slurry applications build up or provide K for dock establishment. Teagasc research has shown that docks germinate and thrive better where there are high potassium (K) levels. A harvested silage field is a good environment for the dock. The dock seed needs light, air and plenty of nutrients to establish. Tight grazing and heavy regular silage cuts leave open swards. Avoiding poaching and overgrazing will limit the space for docks to emerge. In this regard, having a fertile soil with adequate levels of Nitrogen, Phosphorous and Potassium along with a suitable pH for grass growth is hugely important. Maintaining a dense, leafy grass sward will smother out emerging docks. The best control of all for docks is good grassland management. Always spray seedling docks at 4-6 weeks after re-seeding. The trials have also shown that docks that emerge in the following years rarely establish due to competition from the grass, as the dock seed does not get the correct light signal to germinate. Applying the herbicide at this stage of the docks development results in almost complete elimination of the docks. Teagasc trials have shown that longer term (up to 5 years) control of docks can be achieved by applying a suitable herbicide onto small docks shortly after re-seeding. Use highest label rates where rootstocks are well established.

These are best applied in good growth conditions and will give season long control. These products do not harm clover but Prospect may have some effect on the constituent grasses in the sward. These products will eliminate clover.Įagle or Prospect may be applied.

#Dockstar pro herbicide plus#
Use of herbicides based on aminopyralid, dicamba, triclopyr, fluroxypyr, etc., (Dockstar Pro, Forefront T, Bandock EW, Starane 2, Reaper etc) will give at least season long control (possibly 2-3 years significant reduction in numbers and re-growth of docks) plus a wide range of common grassland weeds. Allow adequate time between spraying and cutting silage for the herbicide to work.

Use the highest water rates on the manufacturer’s label for best effects.Do not apply chemicals in a period of drought as the chemical will not be taken up by the plant leaves in sufficient quantities.Treat when the docks are actively growing, in the rosette stage up to 25cm high or wide.If seed stalks are seen on the plant or if the dock has diseased leaves or is under pest attack it is better to cut/top or graze and allow re-growth of the docks before applying chemical.In Grassland: Best control of docks will be achieved in good growing conditions when docks are actively growing and nutrients are actively being transported to new foliage and roots. Scottish data indicates that dock seeds can remain viable for 50 to 70 years if buried in soil and will germinate when conditions of light and soil temperature are suitable. The other extraordinary fact is the longevity of dock seeds. Seed Production & Survival: It has been estimated that one mature dock plant can produce up to 60,000 viable seeds per year. The dock has huge root reserves its tap root can reach a metre deep in mature plants. Docks have a wonderful survival mechanism. Docks must be the most despised and best known persistent weed problem on many intensive grassland farms.ĭocks will seriously limit grassland output and productivity unless controlled.Ī heavy infestation of docks in a silage crop can reduce yields by up to 10%.
