Application Information
Apply using equipment that ensures uniform and thorough coverage of each seed piece. Cut pieces should be treated
immediately after cutting. Treated seed pieces should be planted in soil above 7°C with adequate soil moisture
required for planting. If cut seed needs to be stored or held for a few days, make sure that there is adequate cool air
(15.5
°C) movement through the pile of cut seed potatoes at relative humidity of 85-90%. Cut and treated seed should
not be piled above 1.8 m in height.
How it Works
Fludioxonil is a phenylpyrrole chemistry that possesses contact and local penetrant properties. Mancozeb is a
dithiocarbamate fungicide with contact activity.
Restrictions
