Lucerne Advisor Series: How treated lucerne seed improves your stand

Lucerne is a long-term investment — but the first few weeks can make or break your stand. Poor germination, patchy emergence and early insect or fungal damage are common reasons why lucerne fails to persist.

That’s where seed treatment makes a difference. Whether you’re sowing now or preparing for next season, here’s why treated lucerne seed is worth it.

Why use lucerne seed treatments?

Lucerne is more sensitive at emergence than many other pastures. Germination can be uneven in dry or crusted soils, and seedlings are highly vulnerable to:

• Soil-borne fungal diseases (like Pythium or Phytophthora)
• Insect pests (like aphids and nematodes)
• Poor nodulation in paddocks with low background rhizobia

Treated seed gives lucerne a head start by:

• Improving germination speed and evenness
• Protecting roots from early pest and disease losses
• Ensuring nitrogen-fixing rhizobia are present at the root zone from day one

What is Goldstrike XLR8®?

Goldstrike XLR8® is a high-quality seed coating developed specifically for lucerne. With innovative technology it supports the crop during establishment and throughout the season, allowing for stronger and more vigorous plant growth. It includes:

The coating breaks down naturally in the soil. It’s designed to stick to the seed (low dust), flow well through drills, and perform consistently in a range of sowing conditions.

Bare seed vs treated seed

Using bare seed may seem like a cost saver — but the risk to early establishment often outweighs the difference in price.

Many re-sown paddocks fail not because of the seed — but because the young plants never stood a chance.
