====================================================================
A. A. MacNab, Plant Pathology Dept., Penn State University

The Commonwealth of Pennsylvania has notified the U.S. EPA of the State approval 
of the registration of "Terramaster 4EC," SLN No. PA 03-0005, EPA Reg. 
No. 400-422 for control of Pythium and Phytophthora in Greenhouse Tomato 
production.

Growers who use Terramaster 4EC in greenhouse tomatoes must have a copy of 
the supplemental label, and must follow all applicable directions, restrictions, 
and precautions on the EPA registered label.  

The following is a copy of instructions for application via drip irrigation:

Apply 6-7 fluid ounces of Terramaster 4EC per acre in a 0.01% solution (6.5 fluid 
oz. in 500 gal water) no sooner than 3 weeks after transplanting.

Reapply as needed, 6-7 fluid oz. of Terramaster 4EC per acre in a 0.01% solution, 
no sooner than 3 weeks after a previous application.

Do not exceed 27.4 fluid oz. of Terramaster 4EC per acre per crop per season.

Do not apply Terramaster 4EC closer than 3 days before harvest.

Uniform distribution of Terramaster 4EC through the growing medium is essential 
for best results.  Localized over-dosing may cause crop damage and under-dosing 
may cause ineffective disease control.

Terramaster 4EC should be introduced into the growing medium only after the 
medium has been thoroughly irrigated to ensure adequate product movement 
through the growing medium.  Continue irrigation until the entire desired quantity 
of Terramaster 4EC per acre has been introduced.

Do not mix Terramaster 4EC with other pesticides or fertilizers unless 
compatibility tests have shown complete compatibility.

Apply Terramaster 4EC to a small crop area to ensure crop safety before 
applying to a broad crop area.

THIS LABEL INFORMATION IS IN ADDITION TO THE STANDARD FEDERAL LABEL 
PRINTED ON THE CONTAINER.

Follow all applicable directions, restrictions, and precautions on the EPA 
registered label.
The supplemental label must be in the posession of the user at the time of 
the pesticide application.
