Slaters

  • Slaters can cause extensive crop damage to emerging seedlings.
  • The Australiodillo bifrons slater species has the ability to swarm over a soil surface.
  • Finding black Portuguese millipedes and slaters in a crop does not necessarily mean damage will occur.
  • –Management options are limited after crop emergence so prevention is a key part of control.

Constraint - Slaters

Description

  • The common slater grows up to 20 mm long and is often pale grey with brown, yellow or
    orange hues

  • Armadillidium vulgare rolls into a ball when disturbed, grows up to 18 mm long and is dark brown to black

  • Australiodillo bifrons is about 7-8 mm long and 4mm wide with a flat, oval-shaped body, light brown with irregular dark spots and stripe down the middle of its back

Symptoms

  • Slaters feed on emerging canola seedlings

Damage

  • Damage to emerging canola seedlings can reduce plant density and may produce thin patches in the paddock

  • Finding slaters in a crop does not necessarily mean damage will occur

Control

Reducing organic matter and stubble retention leading into sowing may reduce the risk of seedling damage as slaters are consumers of organic matter.
