  • 3 actives delivering effective translocation and wide spectrum of weed control
  • Controls many weeds such as chickweed, fat-hen, mayweeds, buttercups, docks and thistles
  • Convenient size pack which at 2 L/ha treats 1.5 ha (3.7 acres)
  • Good grass safety
  • Great versatility with use in established grassland, new sown leys, grass grown for seed and maize
  • Rainfast in 2 hours

Pastor® Trio is very safe to grass, has a grazing interval of just 7 days - this may be longer if foliage of poisonous weeds such as ragwort is present, and it is valued for its utility of use across crops and its control of a very wide range 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 Corteva Agriscience recommend topping to even up growth of targets and applying Pastor®Trio to the re-growth 2-3 weeks later.
