Product information

Pastor® is the leading product for broad spectrum weed control in permanent grassland, including common nettle, curled and broadleaved dock, creeping and spear thistle. Whether you have long term pasture, hay meadows or silage fields, Pastor is a suitable product to effectively tackle your weed worries!

Pastor allows a flexible application program for established grassland management, where rates can be adjusted to suit weed size and spectrum. Single applications and split applications are supported to allow optimum timing for control of weeds.

For best results apply when weeds are actively growing and have reached the optimum growth stage.

It’s common that weeds emerge at different times and different plants can be at different growth stages. In this scenario Dow AgroSciences recommend topping to even up growth of targets and applying Pastor to the re-growth 2 – 3 weeks later.

Maximise success – do it with PRIDE

Pastor contains triclopyr which means long-term control of docks is far better than using fluroxypyr alone, and clopyralid adds excellent performance on thistles.

Pastor can be used once at a rate of 4.0 L/ha or twice in the same year at 2.0 L/ha. Apply between 1st March and 31st October. Apply with a water volume of 300 L/ha.
If weed numbers are high, or if the grass sward is dense, increase to 400 L/ha. Reducing water volume, to speed up spraying operations can lead to poorer long-term control.

Use in grassland for grazing or cutting. Take stock out during spraying then return no sooner than 7 days later. Once sprayed, wait a minimum of 3 weeks prior to any planned cutting to maximise translocation into roots.

Pastor is not approved for use by hand-held equipment, e.g. knapsack or lance. Choose GrazonPro for these uses. Target actively growing plants in the rosette stage and up to 250mm across or high. If larger than this consider topping and spraying the regrowth 2-3 weeks later.

Avoid treating weeds suffering from waterlogging, drought stress or cold stress. Pastor is LERAP Category B, meaning a 5 metre area must be left unsprayed next to a flowing or static water body, or 1 metre unsprayed near dry ditches.
