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.

Mixing and Application
Fill the spray vat with good quality water. With the agitation system operating, pour the required quantity of Grochem Tribasic Liquid 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 Grochem Tribasic Liquid Fungicide. Sprays should be agitated continuously.
Wetting Agents
The addition of Spraymate Activator is required when Grochem Tribasic Liquid Fungicide is applied to brassicas, faba beans, peas, and onion. A wetting agent is also required when applied as a concentrate spray or by aircraft.
Application Methods
Dilute Spraying: Use a sprayer designed to apply high volumes of water up to the point of run-off, matched to the crop being sprayed. Add the amount of product specified in the Directions for Use table for each 100L of water.
Concentrate Spraying: Use a sprayer designed and set up for concentrate spraying (applying water volumes less than those required to reach run-off). Calculate the concentration factor by dividing the dilute spray volume by your chosen concentrate spray volume, then multiply the dilute label rate by this factor.
Refer to the registered label Directions for Use table for full crop, disease and rate details. (APVMA 67618)
