Interpretive Summary: Raxil 2.6 combined with LO121 as a seed treatment increased seedling height of winter wheat and the number of crown roots showing symptoms of Rhizoctonia.

Technical Abstract: Treatments with Raxil 2.6 combined with L0121 AI significantly increased plant height and the number of seminal roots. Seed treatments did not affect the number of crown roots, but treatments with Raxil 2.6 plus L0121 at 75 and 100 ppm reduced the percent of crown roots showing Rhizoctonia symptoms. Seed treatments did not significantly affect stand count and yield, although both Raxil XT treatments had the highest numerical yield and the nontreated plants had the lowest yield.
