SHORTT, B. J., and J. B. SINCLAIR. 1980 . Efficacy of polyethyleneglycol and organic solvents for infusing fungicides into soybean seeds. Phytopathology 70:971-973. Soybean (cultivar Bonus) seeds treated with one of six contact or six zones and a greater reduction of seedborne Phomopsis sp. occurred when systemic fungicides in acetone, dichloromethane (DCM), or aqueous benomyl and sisthane were infused with PEG than with either acetone or polyethyleneglycol (PEG) were assayed for fungicide

... ity. Activity was DCM. No treatment was 100 percent effective. Acetone and, to a greater detected in seeds treated with the systemic fungicides benomyl, carboxin, extent, DCM killed Phomopsis sp. borne within the seedcoat, however, they sisthane, and thiabendazole. Solubility of the fungicides in the solvents was damaged exposed cotyledonary tissues. Increased cotyledonary damage not related to uptake by the seeds. Benomyl, sisthane, and thiabendazole was associated with increased recovery of Bacillus subtilis. The efficacy of were detected in seeds treated with acetone, DCM, or PEG, however, any treatment depended on the fungicide and solvent-carrier combination. carboxin was detected only in seeds treated with PEG.
