Tribasic Liquid SC is a flowable copper fungicide formulated for use in agricultural crops to protect against a range of fungal and bacterial diseases on fruit, vegetable, nut, and ornamental crops. Its fine particle size improves coverage and adherence to plant surfaces for effective disease protection.
Active Ingredient
• Copper (Cu): 190g/L
Present as tribasic copper sulphate, providing protectant fungicidal action.
Mode of Action
Tribasic Liquid SC is a protectant (non systemic) fungicide that works by coating plant surfaces with copper ions that inhibit spore germination and disease development. The ultra fine particle size enhances coverage and weatherability, increasing effectiveness.
Fungicide Resistance Group: Group M1 (copper-based fungicide).
Suggested Uses & Crops
Tribasic Liquid SC is typically used for disease protection on a range of horticultural and agricultural crops such as:
• Fruit crops: apples, citrus, stone fruit
• Vegetables: tomatoes, cucurbits, leafy vegetables
• Nut crops: almonds, macadamias
• Ornamentals and other high value crops
Exact registered uses, application rates, and crop lists should always be verified on the registered label for your region.
Features & Benefits
• Easy to use liquid formulation improves measuring and application.
• Extremely fine particle size enhances coverage, stickiness, and availability of copper ions on plant surfaces.
• Lower visible residue compared with other copper products, reducing staining on produce.
• Good weathering properties maintain protective film during rain or irrigation.
• Low rates of metallic copper reduce environmental load while maintaining efficacy.
Typical Mode of Application
• Application Method: Aerial or ground spray - uniformly cover foliage with dilute spray mix.
• Spray Volume & Concentration: Follow label instructions; dilution depends on crop, disease pressure, and equipment.
• Re entry Interval (REI) & Withholding Period (WH): As specified on the registered product label for each crop.
Safety & Handling
• Hazard Classification: Copper fungicides are hazardous; follow all safety directions, wear appropriate PPE, and prevent spray drift.
• Storage: Store in original container, tightly closed, in a cool, dry place away from ignition sources and children.
• Poison Safety: Keep out of reach of children; read safety directions before use.
• Comply with all local regulatory requirements for handling, transport, and disposal.
Compatibility
• May be tank-mixed with other plant protection products if compatible; always conduct a jar test and follow label recommendations for mixtures.

- Target spot/Early blight (Alternaria solani), Irish blight/Late blight (Phytopthora infestans): 280mL/100L or 3.0L/ha - Apply from crop emergence to maturity at 7-10 day intervals. May reduce yield if applied under dry conditions
Note: DO NOT use on aquatic root and tuber vegetables
Ornamentals
- Bacterial leaf spot: 280mL/100L - Apply at first sign of disease, repeat every 10 to 14 days as required. Ineffective against bacterial wilt of carnations caused by Pseudomonas andropogonis. Small scale evaluations recommended first to test for phytotoxicity
Tobacco Seed Beds (Qld, NSW and Vic only)
- Wildfire, Angular leaf spot (Pseudomonas syringae pv. tabaci): 560mL/100L - Apply every 7 days
- Algae (Qld only): Apply when algae first appears
Mixing and Application
Fill the spray vat with good quality water. With the agitation system operating, pour the required quantity of Nufarm Tri-Base Blue Fungicide into the spray vat in a steady stream. DO NOT attempt to pre-mix in water before adding to the spray vat. If other pesticides are being applied, prepare and thoroughly mix them before adding Nufarm Tri-Base Blue Fungicide. Sprays should be agitated continuously.
Wetting Agents
The addition of Nufarm Activator® is required when being applied to brassicas, faba beans, peas, and onion, irrespective of the method of application. A wetting agent is also required when applied as a concentrate spray or by aircraft.
Application Methods
Dilute Spraying: Apply sufficient water to cover the crop to the point of run-off. Avoid excessive run-off. Add the amount of product specified in the Directions for Use table for each 100L of water.
Concentrate Spraying: Calculate the concentration factor by dividing the dilute spray volume by your chosen concentrate spray volume. Multiply the dilute label rate by this factor. For example: if dilute spray volume is 1500L/ha and concentrate volume is 500L/ha, the concentration factor is 3X. If the dilute rate is 10mL/100L, the concentrate rate becomes 30mL/100L.
Crop-Specific Applications
- Deciduous Fruit and Almonds: Apply as dilute or up to 2 times concentrate spray using air-blast spray with cone nozzles preferred
- Citrus and Litchi: Apply only as dilute spray. Oscillating boom sprayer preferred over air-blast sprayer
- Avocados & Mangoes: Apply as dilute or up to 3 times concentrate spray with cone nozzles preferred
- Vines: Apply sufficient volume to wet all leaf surfaces to point of run-off as medium to fine spray using cone nozzles
