After a special emergency-use request by the Washington State Potato Commission and the National Potato Council, the EPA has approved use of Tattoo C fungicide.
The action was the result of months of coordination. The final decision to pursue the Section 18 when a full registration had not been given was made in May.
This is a regional-specific exemption for the use of propamocarb hydrochloride plus chlorathalonil to control late blight on potatoes in Washington and Oregon.
Tattoo C is manufactured and marketed by Aventis.
