Opinions of Experienced Users 



Semesan is recognized by the U. S. Department of Agri- 

 culture and the Green Section of the U. S. Golf Association 

 as the best fungicide for preventing and curing both large 

 and small "Brown Patch" of grasses. 



In Southern Idaho, Semesan-treated beans, with their 20 

 to 40% increased yields, so convinced prominent growers 

 that they unite in saying they: "will always use Semesan 

 for treating bean seeds, as well as their other crops." 



Florists write us such tributes as: "We used Semesan on 

 poinsettia cuttings last summer with excellent results;" and 

 "My Semesan-treated aster seeds gave an almost perfect 

 stand as nearly every seed germinated." 



The U. S. Department of Agriculture's Circular No. 376 

 recommends treatments with Semesan as the most success- 

 ful means known for preventing and controlling the "Crown 

 Gall" disease of apple grafts. 



The TJ. S. Department of Agriculture, in collaboration 

 with the Illinois and Iowa State Experiment Stations, dem- 

 onstrated that Semesan Jr. was a most effective dust disin- 

 fectant for controlling the diseases and increasing the yields 

 obtained from infected field and sweet corn seeds. 



Agricultural authorities in the United States, Canada, 

 Australia and New Zealand, report that Semesan has given 

 excellent results in the control of barley, and wheat 

 diseases and in addition increased germination, and enlarged 

 crop yields. 



The Idaho Agricultural Experiment Station reported that 

 Semesan Bel: " — when applied to the uncut presprinkled 

 tubers (potatoes) at the rate of three ounces to the bushel 

 gave better control under field conditions than any other 

 treatment tested."

THE SEMESAN DISINFECTANTS have revolutionized seed disease 

 treatment and represent the most remarkable advancement of the cen- 

 tury in scientific agriculture. Trained observers testify that they not 

 only successfully control seed, plant and soil diseases but also exert a 

 stimulatory effect upon the growth of seedlings and plants with a conse- 

 quent increase in yield and improvement in quality of the crops. 



SEMESAN — Commercial results prove that Du Pont Semesan is the 

 ■premier seed, plant and soil disinfectant because it is the only chemical which 

 can be applied in either the liquid or convenient dust form to prevent or con- 

 trol effectively a most diversified variety of parasitic diseases and fungoid 

 growths borne by seeds, bulbs, corms, roots, tubers, plants and grafts, as 

 well as some of those which infest the soils. Too numerous to mention here 

 are the uses for which Semesan is endorsed by agricultural authorities, but 

 booklets containing all the facts will be gladly furnished. 



Proof that Semesan Increases Germination 



To prove to a skeptical canner that Semesan would increase the ger- 

 mination and yield of his corn seed, we induced him to select a total 

 of 40 kernels from five average ears. Twenty were dusted with Seme- 

 san, while the other 20 were untreated. These seeds were then allowed 

 to germinate in his office with the results shown. On the right the Seme- 

 san treatment developed 100 % of vigorous, healthy seedlings, while 

 on the left are shown the untreated seeds, only 85 % of which germinated 

 weakly and of these three-quarters died from disease infections. 



Semesan is harmless to seed and plant life but thoroughly sterilizes prac- 

 tically all kinds of seed pieces against the disease germs or fungous spores 

 that adhere to the seed coats, as well as many of those that exist internally. 

 Unhandicapped by diseases, Semesan-treated seeds are thus stimulated to 

 vigorous sprouting during the critical period of their early growth and con- 

 sequently bear more and finer crops than can those seeds which do not 

 receive the beneficial treatments with Semesan. 



SEMESAN Jr. — This modified form of the parent product, Semesan, is 

 exclusively a dust disinfectant used principally for the ear, root and stalk 

 rots of field and sweet corn but also for the treatment of cereal infections. 

 Under Government-conducted field tests, Semesan Jr. increased the crop 

 yields from diseased field corn seeds by approximately twenty bushels to 

 the acre and from similarly diseased sweet corn by as much as 47.7% with 

 an average of practically 12%. 



SEMESAN BEL — To meet the demand for a dust disinfectant to replace 

 the laborious, time-consuming liquid treatments for potatoes, Semesan Bel 

 was invented and can be applied to whole or cut seed potatoes either as a 

 dry powder or a whitewash-like water mixture. In widely separated potato- 

 growing sections it has influenced quicker sprouting, earlier maturity and 

 has caused greater yields of disease-free potatoes and better disease-control 

 than any other treatment known.
