This research was conducted to evaluate a mixture of dry powder formulations of Apron and captan on percent pure live seed (P15) emergence and emergence index (EI) in sunflower (Helianthus annuus L.) and safflower (Carthamus tinctoious L.) seed lots of varying vigor levels. Treatments were evaluated in the field ând in a growth chamber using the cold soil test. Results indicated that PLS emergence of the low-vigor seed lots of both crops increased due to fungicide treatment to a higher degree than did high-vigor seed lots. Percent PI-S emergence in the field and the growth chamber for each crop was significantly (P < 0.05 or P<0.1) correlated. This suggests that seed treatment is important in stand establishment for low vigor seed lots due to its protective effect âgainst seed and soil-borne microorganisms
