ROW CROPS: Onions
Trident fumigant formulations are an optimal choice to create a healthy onion field for a healthy yield. The first 6 to 8 weeks are especially vital for developing root growth in onions. Injecting Trident fumigants into the soil before planting creates a zone of protection against disease and pest, buying time for the developing young plants to yield a healthy and vigorous onion root.
- Protects Young Root Formation
- Promotes Health Bulb Development
- Better utilization of nutrients
- Requires less irrigation
- Longer harvest window
- Higher marketable yields
Benefits of Trident Fumigation

Strike out Soil Disease in Onions
Strike soil fumigants provide a barrier of protection from soil borne disease in the first 6 to 8 weeks, buying time for the onions to yield a healthy and vigorous root. Soil health studies prove that Strike suppresses disease while also supporting biological diversity and soil health overall.
Pink Root: A Menace to Onion Production
Pink root of onion caused by Phoma (Pyrenochaeta) terrestris is a devastating soilborne pathogen of onion worldwide. Infected roots are noticeable by a pink to red color at early stages of the disease and eventually dark in color and death of the plant. The pathogen has a wide host range.
How Trical Has Helped Onion Growers
TriCal Australia knew it could help solve yield problems on an onion farm in Myalup, WA. Soil health was deteriorating, with higher rates of Pink Root, Rhizoctonia, Fusarium, Verticillium wilts, Sclerotinia, Pythium, and parasitic nematodes all being detected in soil DNA tests.
