Late blight
40 - 80
mL
Use the low rate (40 mL product/acre) for preventative applications or very low
disease pressure, increasing the rate as disease pressure and/or crop development
increases, up to a maximum rate (80 mL product/acre). For late blight tuber rot
control, ensure that the last 2 - 3 applications of Ranman 400SC prior to desiccation
are made at the maximum rate (80 mL product/acre) following resistance
management practices. After one application, alternate Ranman 400SC fungicide
with at least one application of fungicide having a different mode of action for
control of late blight. Do not make more than 6 applications per year.
Note
:
Must be tank mixed with non-ionic or organosilicone surfactant at 0.6 L/acre.
Registered Tank Mixes
None registered.
Application Information
How to Apply
:
Ground application only. Do not apply by air.
Water Volume
:
Apply in sufficient water volume to obtain coverage of the foliage. Spray volume ranges from 80
to 242 L/acre.
How it Works
The active ingredient cyanofamid is a member of the cyanofamidazole class of chemistry and has preventative and
protectant activity. Although Ranman 400SC has limited systemic activity, it should be treated as a protectant
fungicide and applied before the disease enters the crop.
Restrictions
Effects of Rainfall
:
Do not apply if heavy rainfall is imminent.
Pre-harvest Interval
: 7
days.
Re-entry
:
Do not enter treated areas within 12 hours.
Re-cropping
:
A plant-back interval of 30 days is required.
