Exclusive to Notman Pasture Seeds

Providing superior pasture protection under insect pest attack

Barrier is a specialist insect tolerant permanent pasture variety for use where insect pests are a serious threat to the productivity and persistence of your pastures. Barrier is a perennial festulolium grass variety (ie an inter-species cross) of roughly 50% meadow fescue and 50% perennial ryegrass parentage.

Containing the GrubOUT® U2 endophyte, Barrier has high endophyte infection levels, and strong insect pest tolerance of a wide range of insect pests including grass grub larvae, black beetle adults and larvae, porina caterpillar, black field crickets, Argentine stem weevil etc. It has been proven to be lethal to porina caterpillar.

NOW STRONGER THAN EVER

Barrier is now even more effective against insect pests. Barrier has improved endophyte infection levels, and higher loline levels, enabling even higher tolerance of insect pests.

SAFER FOR LIVESTOCK

Barrier is highly palatable to livestock, with high livestock performance potential and won’t cause grass staggers or heat stress, so it can be used safely with sheep, cattle, deer and goats.

GrubOUT® U2 has been comprehensively trialled and tested too – in the laboratory and in the field, on farms throughout Australia & NZ.

DAVE BARRY - LABERTOUCHE

On March 25th I planted perennial pasture again with Barrier, a new variety which provides above and below ground protection against insect pests. Barrier has done well this season, coming up to its 5th grazing.

BARRIER MANAGEMENT

  • A sowing rate of 25-30kgs is recommended, along with clovers and herbs.
  • Sowing it shallow, into a fine, firm, moist and well compacted seed bed, when soil temperatures are 12° C or more will aid establishment.
  • Full cultivation is recommended over direct drilling or broadcasting to get best results.
  • Sowing Barrier with other grasses isn’t recommended, as doing so could give insects a feed source.
  • Where high insect pest populations exist (eg grass grub, porina, black beetle) get them under control first through cultivation and/or the application of a suitable insecticide. And always use treated seed in such situations.
  • Rotational grazing is recommended to prevent over-grazing.
