Kendon Triforine Rose Fungicide – Powerful Protection Against Rose Fungal Diseases

What diseases does Kendon Triforine Rose Fungicide treat?

It controls black spot, powdery mildew, and rust—three common fungal issues in roses. It works both as a protectant and curative, helping prevent new infections and reduce active outbreaks when used as part of a regular program.

How and when should I apply Kendon Triforine Rose Fungicide?

Spray every 7–10 days during disease-prone periods, starting with new growth in warm, humid weather. Apply to the point of runoff, aiming for good foliage coverage. Avoid spraying during heat, cold, or when rain is imminent.

What’s the correct dilution rate for Kendon Triforine Rose Fungicide?

Mix 15 mL per 1L of water. For example, 30 mL in a 2L sprayer. Always dilute just before spraying—don’t pre-mix and store. If you over-concentrate the mix, dilute it back to the proper rate before use.

Can I mix Kendon Triforine Rose Fungicide with other products?

It's compatible with certain insecticides like Kendon Pyrethrum Insect Killer, but avoid mixing with multiple products or adding wetting agents. Always jar-test before combining sprays to prevent plant damage.

Is Kendon Triforine Rose Fungicide safe for kids, pets, and bees?

Keep kids and pets away during application and until spray dries. Avoid spraying directly on pollinators and apply during low bee activity. Use gloves, long sleeves, and eye protection when spraying, and rinse skin or eyes immediately if exposed.

What equipment can I use to apply this fungicide?

Use a hand sprayer, pump sprayer, or knapsack. Hose-end sprayers are possible but less accurate. Clean your sprayer thoroughly after use and never pour leftover mix or rinse water into drains or waterways.

Should I rotate Kendon Triforine Rose Fungicide with other fungicides?

Is Kendon Triforine Rose Fungicide safe for indoor or potted roses?

Yes, but ensure good ventilation and avoid overspray indoors. It’s best to spray outside and let the plant dry before bringing it back in.

What’s the best practice routine with Kendon Triforine Rose Fungicide?

Remove infected leaves, spray at 15 mL/L every 7–10 days during active conditions, avoid wetting agents, and don’t spray in extreme weather. Rotate fungicides to manage resistance and improve long-term results.

How much area does a 250mL bottle cover?

At 15 mL per litre, a 250 mL bottle makes about 16–17 litres of spray, which is typically enough for several treatments of a small to medium rose garden, depending on plant size and coverage.

Can I use Kendon Triforine Rose Fungicide on other plants?

Only on plants listed on the label. It’s not safe for edibles like vegetables or fruit trees. For non-listed ornamentals, don’t apply unless approved by the label or a professional recommendation.

Why might I still see black spot or mildew after spraying?

Common reasons include inconsistent spraying, poor coverage, leaf wetness, or high disease pressure. Improve air circulation, remove fallen leaves, spray regularly, and avoid overhead watering to get better control.
