Mix components

Formulation 2025

Component
The only early flowering commercial annual ryegrass with ARGT resistance that can inoculate Wimmera pastures for future protection against ARGT.
A very versatile and proven subterranean clover with good seed set ability that combines well with other species in this mix.
Annual legume with good spring production, well suited to our Mediterranean-type climate and growing satisfactorily on a wide range of soils. Tolerates low pH soils, has good insect tolerance and is a non bloating, palatable forage.
A mid-maturing, semi-erect self-regenerating annual clover selected for its tolerance to waterlogged and acid soils and clover scorch resistance. Although tolerant to waterlogging it has low salt tolerance. Combines well with other species.
Early maturing hard black seeded variety with good persistence due to the high level of hard seeds. Due to Nungarin's earlier maturity, production declines into late spring.

*Occasionally some varieties in our mix will be replaced with a like-for-like variety where the original is not available or not easily accessible. Varieties in the mix will be specified on the bag label.

About this seed blend

IH Seeds introduced Self Regeneration Mix to cater for the large number of farmers who require an early flowering pasture of annual ryegrass and various clovers that will set seed for regeneration in the following years, and that also gives protection against annual ryegrass toxicity at the same time.

Self Regeneration Mix is based around Safeguard ARGT Resistant Annual Ryegrass, which will successfully cross pollinate with Wimmera, providing ARGT resistance to the following year's progeny. Safeguard flowers early while there are still good moisture levels in the soil, increasing the chances of a successful seed set.

The mix has the potential to provide grazing opportunities during the winter and early spring period before locking up for seed set.

Planting & grazing notes

Optimal sowing time is autumn to winter. Sow at a minimum of 12 kg/ha, or up to 15 kg/ha where there is a likelihood of a higher Wimmera plant population; the higher seeding rate increases the effectiveness of cross pollination with the local Wimmera, increases winter production and assists with second year regeneration. If your background population of annual ryegrass is high, cultivate after the autumn break to encourage Wimmera germination and spray with a non-selective herbicide to reduce Wimmera seed reserves, ideally the year before sowing. If background ryegrass levels are low, plant with minimum soil disturbance. Leave unsown test strips to monitor local ryegrass. Do not sow deep: broadcast and harrow lightly, or preferably sod seed with a triple disc. Check emerging seedlings for insects such as redlegged earth mite. Once established, lightly graze at about 6 weeks or 6–8cm, ideally with younger or lighter beef cattle or sheep, then graze rotationally between 10–15cm, to no lower than 3cm. Graze or cut through late winter and early spring to ensure Wimmera pasture is in a vegetative phase. It is important to keep the paddock tightly grazed until mid-September. Safeguard normally runs to head in early October depending on the area and seasonal conditions. Remove or reduce stock from mid-September so Safeguard and Wimmera head together.

Disease & pest resistance

Contains certified Safeguard ARGT resistant annual ryegrass, which is resistant to the nematode that causes outbreaks of ARGT. Livestock grazing Safeguard pasture have a significantly reduced risk of developing annual ryegrass toxicity in the pasture, hay or grain. It is safe to graze in spring and summer, and with a good management plan over several years it should assist with eradicating and combating signs of ARGT on your farm. It is recommended the paddock is tested in subsequent years to confirm the bacterium is under control. Paradana Balansa is clover scorch resistant.

Stand life

Allow the paddock to run to seed in the first year to provide the following years' regeneration. The clovers are hard seeded for persistence: Dalkeith Sub clover is a medium maturing prolific seeder with a high % of hard seed, making it very persistent; Nungarin Sub clover is early maturing with a high level of hard seed; Hykon Rose is an early flowering hard seeded clover; and Paradana Balansa provides prolific regeneration if it is not cut late for silage or hay and is allowed to set seed. After seed set, when the pasture has fully dried off, stock can return to graze the residues. If managed well, Self Regeneration Mix should continue to provide high quality pasture into subsequent years.

FAQs

How do I reduce ARGT poisoning risk in my annual ryegrass paddocks?

We recommend our Self Regeneration Mix, built around Safeguard Diploid Annual Ryegrass, an ARGT-resistant annual ryegrass. Safeguard cross-pollinates with Wimmera Annual Ryegrass to pass ARGT resistance to the following year's progeny and reduce risk over time. Keep the paddock tightly grazed until mid-September, then remove stock so Safeguard and Wimmera head together, and test paddocks in later years.

What pasture mix suits lower rainfall wheatbelt paddocks that already have Wimmera ryegrass?

Our Self Regeneration Mix suits lower rainfall areas (350mm+) where Wimmera Annual Ryegrass exists. It combines Safeguard Diploid Annual Ryegrass with Dalkeith Subterranean Clover, Nungarin Subterranean Clover, Paradana Balansa Clover and Hykon Rose Clover, and is productive across light sand to heavy soils with a pH of 5.0 (CaCl2) or above.

How much should I sow of an ARGT resistant ryegrass and clover mix?

For our Self Regeneration Mix we recommend 12 to 15 kg/ha, using the higher end where the Wimmera Annual Ryegrass population is likely to be high to improve cross-pollination. Do not sow deep: broadcast and harrow lightly, or preferably sod-seed with a triple disc. Where background ryegrass is low, sow with minimum soil disturbance.

How should I graze a new self-regenerating pasture in its first year?

For our Self Regeneration Mix, graze lightly at about six weeks or 6 to 8cm to increase tillering, ideally with younger or lighter beef cattle or sheep. Then graze between 10 and 15cm, closing no lower than 3cm. Remove stock from mid-September for seed set, then graze residues after drying off.

What pasture handles a bit of salt on wheatbelt flats and comes back each year?

Our Self Regeneration Mix tolerates mild salinity and regenerates if locked up to set seed each year. It suits light sand to heavy soils with pH 5.0+. For heavily salt-affected or scalded ground, we suggest talking to us about Puccinellia or Tyrrell Tall Wheatgrass instead.

How do I prepare a paddock with lots of Wimmera ryegrass before sowing new pasture?

Where background ryegrass is high, we recommend cultivating and spraying with a non-selective herbicide the year before sowing our Self Regeneration Mix, to reduce Wimmera Annual Ryegrass seed reserves. Where levels are low, use minimum-disturbance sowing. Leave an unsown test strip to monitor local ryegrass.

Can I cut hay from a self-regenerating pasture?

Yes, our Self Regeneration Mix suits winter and early spring grazing and hay. Keep in mind cutting can reduce seed set, and regeneration depends on the pasture being locked up to set seed. Consider cutting only part of the paddock if you want strong regeneration.

What's in Self Regeneration Mix?

Self Regeneration Mix contains Safeguard Diploid Annual Ryegrass, an ARGT-resistant annual ryegrass, plus Dalkeith Subterranean Clover, Nungarin Subterranean Clover, Paradana Balansa Clover and Hykon Rose Clover. Safeguard is early flowering, and the clovers are hard seeded for regeneration and suit a wide range of soils. It is coated with BioNPK Powder S.

How do I know if Self Regeneration Mix has fixed my ARGT problem?

We recommend testing the paddock in the years after sowing Self Regeneration Mix to confirm the ARGT bacterium is under control. Keep the paddock tightly grazed until mid-September, then remove or reduce stock so the mix's Safeguard Diploid Annual Ryegrass and the local Wimmera Annual Ryegrass head together. This helps pass ARGT resistance to the following year's local ryegrass.

Self Regeneration Mix vs Nitro Mix?

Self Regeneration Mix pairs Safeguard Diploid Annual Ryegrass, an ARGT-resistant ryegrass, with sub and aerial clovers for grazing and hay, aimed at paddocks with ARGT risk. NITROMIX is legumes only, focused on building soil nitrogen and structure. Choose Self Regeneration Mix if you want a grass and clover pasture that regenerates.
