Summer control of skeleton weed

Summer control is aimed at controlling the above-ground part of the plant in order to prevent viable seed set.

There are a number of options for controlling Skeleton weed during the summer months

Small infestations

  • Tordon™ Granules can be used for single plants and small infestations, at a rate of 5 to 10g/m2. Sprinkle granules over plants and over the ground in a 1m buffer around each plant. Then cut and remove all stems to prevent seed production while the chemical takes effect.
  • Spot spray with a mixture of glyphosate (450g/L) at a rate of 0.5 to 1.5L/ha plus 1-1.5L/ha FallowBoss™TORDON™.
    Other formulations of glyphosate are available and if used the rates should be adjusted accordingly.
  • Where small numbers of plants are seeding, cut and bag stems before spraying. Burn all cuttings.

Large Infestations

  • Boom spray the whole paddock if infestations are widely scattered, to control possible missed plants.
  • Treat large areas of flowering and seeding plants (where cutting and bagging is impractical) with SpraySeed®250 at a rate of 1 to 2L/ha (minimum recommendation). This treatment will act quickly and prevent further flowering and seeding for several weeks. The addition of 2,4-D amine will improve control and lengthen the period between retreatment.
  • Monitor infested sites regularly, approximately every two to three weeks throughout summer and autumn and after rain events.
