Uptake of Ethylenebis(dithi0carbamate)Fungicides and Ethylenethiourea by Soybeans Ralph G. Nash Radioactivity from soil treatments of 10 to 100 ppm of 14C-labeledethylenebis(dithi0carbamate) (EBDC) fungicides (nabam, zineb, and maneb) and 0.1 to 10 ppm of ethylenethiourea (ETU), a degradation product, is readily absorbed by soybeans and translocated throughout the plant. The presence of ETU on soybean leaves after EBDC foliar treatments decreased rapidly from
