NONE, LOW, MOD, and HIGH is a relative ranking of disease severity at each location. Other diseases noted: SDS = Sudden Death Syndrome
Soybean Cyst Nematode rateds as Resistant (R), Moderately Resistant (MR), Moderately Susceptible (MS), Susceptible (S), or High Susceptible (HS) to HG Type 1.2.5.7/Race 2
Disease ratings at JAX: Frogeye leaf spot ranged from 1 – 61%, averaged 16%; Target spot from 0 – 11%, averaged 2%; Brown spot from 11 – 34%, averaged 20%
Disease ratings at RECM: Frogeye leaf spot ranged from 0 – 18%, averaged 4%; Target spot from 0 – 1%, averaged 0.1%; Brown spot from 11 – 29%, averaged 23%
