CERESAN 



for seed treatment of wheat, oats, barley, 

 sorghum 



Now, only one product is nec- 

 essary for the seed treatment of 

 wheat, oats, barley, rye or sorghum, 

 Ceresan. Here is an easily apphed 

 dust treatment which has proven 

 effective in controlling such seed- 

 borne diseases as bunt or stinking 

 smut of wheat, stripe disease of 

 barley, loose and covered smuts of 

 barley and oats, and covered kernel 

 smut of sorghum. 



This is the only dust treatment 

 which has successfully controlled 

 all of these grain diseases as well as 

 being the first effective dust disin- 

 fectant to be offered the farmer for 

 control of barley stripe and smuts. 

 Ceresan does not injure the seed 

 nor the grain-drill. Only 2 ounces of 

 Ceresan required per bushel of 

 wheat, rye or sorghum, and 3 

 ounces for barley and oats. Easy to 

 apply; economical to use.

SEMESAN JR* 



for field and sweet seed corn 



Applied by the simple dusting 

 operation at the rate of 2 ounces to 

 each bushel of seed corn, Semesan 

 Jr. offers the cheapest and most 

 effective form of disease insurance. 



It is especially effective in con- 

 trolling seed-borne infections of 

 diplodia, gibberelfa, and basispor- 

 ium, without harming the seed 

 embryo in the least. Tests have 

 shown Semesan Jr. to increase the 

 yield even from known disease-free 

 seed. 



Its use protects the seed from 

 rotting in the ground and makes 

 possible earlier planting which gen- 

 erally results in increased yields. 

 Improved germination, better 

 stands, control of certain diseases, 

 increased yields— those are the 

 benefits which thousands of farmers 

 are reaping at a cost of less than 

 3 cents an acre.

SEMESAN BEL 



for white and sweet seed potatoes 



Instead of using chemicals for 

 treating your seed potatoes, which 

 require tedious soaking and which 

 sometimes injure the seed-piece, use 

 the quick, easy, time-saving Seme- 

 san Bel treatment. Simply mix, dip, 

 drain, dry, and the potatoes are 

 ready for planting. Semesan Bel 

 may be used on either whole or cut 

 seed-pieces. Does not injure sprouts. 

 No hot water necessary. A quick 

 dip into the Semesan Bel solution 

 and the seed potatoes are covered 

 with a protecting film of disinfectant 

 which effectively controls such 

 seed-borne disease organisms as 

 scab, rhizoctonia, and black-leg. 



By controlling these diseases, 

 germination is generally increased, 

 stand improved, and the resultant 

 crop of potatoes is bigger and of 

 better quality. Crop increases of from 

 10 to 15 per cent are common. One 

 pound treats 16 to 20 bushels of seed.

SEMESAN 



for flower and vegetable seeds 



Semesan is indispensable to those 

 growing vegetables or flowers 

 whether for market or home use. It 

 may be applied in dust or liquid 

 form to the seed before planting, 

 and is harmless to the seed but 

 deadly to any disease organisms 

 that may be on it. 



Semesan is such a powerful and 

 effective disinfectant that seed 

 treatment with it is ridiculously 

 low in cost, from 34 to 1 cent per 

 pound of seed. One ounce treats 

 15 pounds of seed. Effective in con- 

 trolling damping off, the brown 

 patch disease which affects golf 

 greens, and such devastating gladi- 

 olus diseases as hard rot and scab. 



DuBay Semesan takes the place 

 of the product sold as DuPont 

 Semesan and Bayer Uspulun.
