Insight

Using Maxstim on your onions

Integrating Agriculture+ and Cynosa into early-season plans

For onion growers planning the 2026 season, early establishment and uniformity will be key to maximising yield and quality. Maxstim’s Agriculture+ and Cynosa™ treatments are designed to strengthen your crop right from the start, supporting resilience, growth and marketable yield through every stage.

Why Agriculture+ and Cynosa™?

Agriculture+ is a complex treatment containing a wide range of bioactive components including unique bioflavonoids and polyphenols. These stimulate root development and early plant growth, helping onions establish faster and become more robust.

Cynosa™ combines orthosilicic acid with specific bioflavonoids to enhance plant structure and boost natural disease resistance. Used together, they deliver stronger, more uniform crops and better performance under environmental stress.
