PRODUCT INFORMATION 
Gammasan Seed Treatment is a specially formulated combination of lindane for protection against 
wireworms and captanror protection against fungus diseases of corn and sorghum seeds and seedlings. 
Treat only those seeds needed for immediate use, minimizing the interval between treatment and 
planting. Use only at recommended rates. Lower amounts may not give desired conh·ol. Excessive 
amounts may cause seed injury. 
APPLICATION INSTRUCTIONS 
Planter Box Application Rate - Use Gammasan at a rate of 2.7 oz. (1 packet) for 50 pounds of seed. Mix 
thoroughly with seed in planter box as follows: 
1. Fill the planter box one-half full of seed. 
2. Then add one-half the required amount of Gammasan and mix thoroughly with an axe handle or 
paddle (an axe handle or paddle used for seed treatment purposes only). 
3. Then add the remaining one-half of the seed and then the remainder of the Gammasan and mix 
again until all seed is uniformly covered. 
4. Never use bare hands to mix and treat seed.

Vacuum Planters - Pour 50 pounds of seed into the planter box. Pour enough Gammasan on top of the 
seed to treat 50 pounds of seed. Mix thoroughly with an axe handle or paddle until seed is uniforfnly 
covered. Then add any plantability additive at the recommended rate to improve seed flowability (talc, 
etc.). Mix thoroughly once more with an axe handle or paddle to get uniform coverage. This process 
will provide the best seed flow through the planter while providing all the benefits of a seed treatment 
product. 
Regularly inspect planter plates and clean as required. If the seed treatment increases the friction 
between seed sufficient to reduce the rate of delivery through a grain drill, 1 ounce of graphite per 
bushel of seed should be added as a drill lubricant. Adjust the seed drill to give the required rate of seed 
delivery with the treated seed. 
Use seed within one month of treatment. 
Electric Eye Population Monitors: At the end of each day of use, or as often as required depending on 
field conditions, clean the electric-eye monitors with brushes provided by the planter manufacturer, 
according to their directions. Under extremely humid weather conditions, this cleanup process may 
need to be done more often. 
Treat only those seeds needed for immediate use, minimizing the interval between treatment and 
planting. Do not store excess treated seeds beyond planting time. Treated seed mus~ not be used for or 
mixed with food or animal feed, or processed for oil. 
STORAGE AND DISPOSAL 
Do not contaminate water, food or feed by storage or disposal. 
STORAGE: Protect from excessive heat. Store in a cool, dry place away from water, food and feed. Do 
not store with food for human consumption, feed or forage to be fed to any or all livestock animals. Do 
not transport or store near feed or feed. 
PESTICIDE DISPOSAL: Pesticide wastes are acutely hazardous. Improper disposal of excess 
pesticide, spray mixture or rinsate is a violation of Federal law. If these wastes cannot be disposed of by 
use according to label insh·uctions, contact your State Pesticide or Environmental Control Agency, or the 
Hazardous Waste representative at the nearest EPA Regional Office for guidance. >-
CONT AINER DISP05-AL: Completely empty each packet into application equipment. Then dispose 
of the packet in a sanitary landfill or by incineration if allowed by state and local authorities. If 
incinerated, stay out of smoke.
