Is a Susceptible Hybrid a Bad Hybrid?

When predicting which disease may cause problems each season, start with your hybrid’s seed guide to determine the ratings for each disease. Depending on the hybrid, there are different susceptibilities. Farm Journal’s Associate Field Agronomist Missy Bauer explains how using the seed guide will help with managing disease proactively.

She explains how hybrids respond differently by using two hybrid pairs, with one of each having gotten fungicide treatment at silking while the other had not. This is a good procedure for determining how responsive each hybrid is to the fungicide and how it may keep the upper leaves free of disease.

After testing out each hybrid and discovering the level of management required for each plant, Bauer stresses that a susceptible hybrid does not mean that it is a bad hybrid. In some instances, more susceptible hybrids can prove to be higher yielding. "What it does tell us," she says, "is that if I take this hybrid and add a little bit of management to it, it can really make a pretty significant difference in yield."

It is important to explore what hybrids are out there, but also how manage them. That balance will produce the highest yielding plant.
