HOULD SOYBEAN SEED BE TREATED WITH A SEED-PROTECTANT FUNGICIDE? 



=ed treatment fungicides- -containing captan, thiram, or chloranil- -protect seed against 

 ;ed-decay fungi and help ward off soil-born organisms that infect just before or just 

 fter emergence. 



l Illinois and surrounding states, soybean seed treatment tests have usually shown that 

 roper seed treatment improves the germination of poor-quality seed, but has little or no 

 Efect on the germination of high-quality seed- -except under very stress conditions such 

 5 cold, wet soil and deep planting. 



;ed treatment often increases the emergence of low- germinating seed by 10 to 50 percent, 

 it such increases are seldom accompanied by increases in yield. Our thoughts may change 

 l the above points based on extensive trials planned this spring. You will hear more about 

 lis after harvest. 



; feel that farmers should plant only top-quality, certified seed (germination 85 percent 

 : more) . This gives the soybean grower the best protection against low- germinating seed 

 lat is shriveled, cracked, moldy, badly weathered, split, or immature. Sowing top-quality 

 ?ed is the best guarantee for a thick, uniform stand of vigorous plants. 



IUIT DISEASES ARE ACTIVE NOW 



irays should be applied to strawberries, brambles, apples, pears, stone fruits, and grapes 

 : 7- to 10-day intervals. This will keep new foliage (and later fruit) protected during 

 ^riods of wet weather when infections occur.
