YLD= Avg. Yield @ 13% moisture MS= Varieties that have any MS letter in common are not statistically different in yield at the 5% level of probability.   *Treated plots sprayed with Quadris TOP SBX @ 7 oz./Acre + 0.25% Induce @ R3 growth stage. RECM varieties planted June 3, sprayed July 29, and harvested Oct 5. JAX varieteis planted June 2, sprayed July 29, and harvested Oct 1.   LOW, MOD, and HIGH is a relative ranking of disease severity at each location. Other diseases noted: SC=Stem Canker; ‘ – ‘ indicate variety was not tested at that location Disease ratings at RECM: Frogeye leaf spot ranged from 0 – 13% with an average of 5%;  Target spot ranged from 0 – 21% with an average of 10%. Disease ratings at JAX: Frogeye leaf spot ranged from 0 – 6% with an average of 2%; Target spot ranged from 0 – 17% with an average of 8%;   Disease ratings & yield data compiled by Dr. Heather Kelly & Alyson Horner from replicated plots at the Research and Education Center at Milan and on-farm location in Jackson. County data provided by Ryan Blair, Ext. Area Specialist, and the extension agents.
