Notes content
Circa early 1950s single sided flyers that demonstrate the benefits of using Nor-Am's Panogen (methylmercury guanidine) antifungal product to treat fungus on the seeds of grain crops such as barley, oats and wheat. The role of Panogen as a fungicide is explained in article in the journal "The Plant Health Instructor" (published 2001, updated 2006) writen by D. E. Mathre, R. H. Johnston, and W. E. Grey and entitled "Small Grain Cereal Seed Treatment". After the initial discovery of the value of organic mercuries for seed treatment in 1912, additional work continued on them. The first commercial formulation called Panogen (= methylmercury guanidine) was developed in Sweden in 1938. Panogen was available as a liquid and beginning in 1948 was widely used in the United States. Later, a dust formulation of ethylmethyl mercury (= Ceresan) was developed and was also widely used in treating small grains. The organic mercury seed treatments were highly effective against common bunt and were so inexpensive that many seed elevators and/or treating stations would apply them for no cost when the farmer brought in his/her seed to be cleaned. Even when a cost was incurred, it usually was no more than 10-15 cents per bushel of seed. The use of the mercury fungicides continued until the 1970’s when concern developed over their toxicity to man and other animals. Residues of these mercury seed treatments were found in game birds that had eaten treated seed that had blown off trucks or had spilled on the ground near seed treating stations. In addition, several unfortunate incidents of human poisoning occurred from people eating treated grain directly, or eating meat from animals that had consumed treated grain. These poisonings finally sealed the fate of the organic mercury fungicides and today they are no longer used in the United States and have limited use in other parts of the world." (See http://www.apsnet.org/education/advancedplantpath/topics/SeedTreatment/top.htm). Most recent literature about Panogen refers to law suits.
