How it Works
The active ingredient cymoxanil in Curzate 60 DF is a highly active, locally systemic fungicide recommended for the
control of late blight on potatoes. It works as a preventative, curative and inhibitive (against sporulation) product.
Curzate offers a unique feature for late blight management called “kick-back” activity. It controls infections that have
already attacked the crop but are not yet visible.
Restrictions
Rainfall
:
Curzate is rainfast within 2 hours after application.
Pre-harvest Intervals
:
Do not harvest within 8 days of treatment.
Re-entry
:
Do not re-enter treated area within 24 hours.
Environmental Precautions
Overspray or drift to sensitive habitats must be avoided. A buffer zone of 50 metres is required between the
downwind point of direct application and the closest edge of sensitive aquatic habitats. Do not contaminate sensitive
habitats when cleaning and rinsing spray equipment and containers. Do not mix, load or apply within 15 metres of all
wells.
Runoff
:
Do not apply product during periods of intense rainfall or to soils saturated with water. Do not apply directly
to standing or running water. Do not apply in areas where surface water from treatment site can run off to adjacent
cropland, either planted or to be planted, or into streams, irrigation waters or wells. Do not contaminate any body of
water, including irrigation water.

Curzate 60 DF is moderately toxic after single ingestion. Acute oral LD
50
(
rats) = 433 mg/kg. Slightly toxic after
short-term skin contact. Acute dermal LD
50
(
rats) = > 2,000 mg/kg.
