Ranman Fungcide 1L (Botritis)

RANMAN® 400SC is a super protectant fungicide with limited systemic activity. To gain optimal performance RANMAN® 400SC needs to be applied before disease infection occurs. Featuring novel chemistry directions. RANMAN® 400SC integrates into disease control programmes as it can be used either in alternation or as part of a mixture strategy. There is no documented cross-resistance of RANMAN® 400SC with other fungicides. RANMAN® 400SC rapidly binds the leaf due to its strong affinity to the leaf’s waxy surfaces, then penetrates into the leaf, providing excellent rain fastness (< 1 hour). RANMAN® 400SC is a Systemic Fungicide for the control of disease in Potatoes.
Active Ingredient:
Cyazofamid (400 g/L) in the form of a suspension concentrate.
- Fungicide Group 21.
- This group is quite unique—useful for resistance management.
What It Controls:(From the NZ label).
- Late Blight (Potatoes).
- Downy Mildew (Onions).
More broadly: (from supporting info).
- Oomycete Diseases like Phytophthora, Pythium, Downy Mildews.
- Important: this is not for general fungi like Powdery Mildew or Botrytis.
How It Works:
- Protectant Fungicide (best before infection).
- Has translaminar / slight systemic movement (moves into leaf tissue).
- Stops all stages of the disease lifecycle.
- It’s strong, but timing is everything—early use is critical.
.Application Basics: (label-style summary).
- General principles.
- Apply before disease appears.
- Use in a tight spray programme (7–10 day intervals).
- Must be used with an adjuvant (wetting agent) for best coverage.
- Coverage matters a lot—it sticks well to leaves and becomes rainfast within ~1 hour.
Timing & Strategy:(Start spraying when).
- Conditions favour disease (wet, humid).
- BEFORE visible infection.
- Rotate with other fungicide groups.
- It’s commonly used as part of a programme, not alone.
Key Safety & Restrictions:(From the label and Standard Warnings)
- Keep out of reach of children.
- Toxic to aquatic environments (avoid waterways).
- Avoid spray drift.
- Use proper PPE when handling.
Resistance Management: (VERY Important).
- Group 21 = single-site mode of action → resistance risk.
- Label + guidance recommend.
- Rotate with other Fungicide Groups.
- Use in mixtures or programmes.
- Don’t rely on it repeatedly by itself.
Practical Takeaways:
- Use early and preventatively.
Ideal for:
- Onions (Downy Mildew).
- Potatoes (Late Blight).
Needs:
- Good coverage + adjuvant.
- Rotation with other Fungicides.
NOT Useful For:
- Powdery Mildew.
- Botrytis.
- General Leaf Spots.
Bottom Line:
RANMAN® 400SC: = Specialist Fungicide for Downy Mildew & Late Blight.
- Very effective, modern chemistry.
- But narrow target + timing-sensitive.
Caution:
Must be used strictly according to label directions.
