Interpretive Summary:

Technical Abstract: Soybeans planted in Northern Ohio in late April may not emerge for 2 or 3 weeks suggesting that seed treatment might be beneficial in stand establishment and seed yield. Seed treatment with the fungicide, Captan TBZ-PCNB, and the insecticide, Lorsban 50, alone and in combination were applied to soybeans planted in late April in 1988 and 1989 at the OARDC, Wooster, OH. A commercial fungicide/insecticide mix, Agrox DL Plus, was also applied. Percent stand and seed yield were determined. The larger seeded variety, Sprite 87, showed a 105% increase in percent stand and 55% increase in seed yield from the fungicide treatment. There was no benefit from the insecticide treatment. For the smaller seeded variety, Resnik, the fungicide treatment increased percent stand 40% and seed yield 13%. The insecticide treatment increased the percent stand in Resnik in 1988 but not in 1989. The percent stand and yield of the fungicide + insecticide and the Agrox treatments were similar to the fungicide only treatment. These results suggest fungicide seed treatment would be beneficial for early planted soybeans.
