Low Head Scab and Vomiitoxin and Very Good Grain Yield and Quality

A June 27 Update: Wheat is now drying-down and is even being harvested in some parts of the state. Thanks in part to cool spring conditions followed by relatively dry weather during early grain-fill, head scab and other disease levels were generally low in most areas; and low disease severity often means very good grain yield and quality. Stripe rust was our biggest disease problem this year, but outbreaks only occurred in pockets within and across fields. Moreover, several of the affected fields were treated with a fungicide which helped to keep this and other later-season diseases in check.

The first set of harvest numbers are showing yields above 80 bushels per acre and test weight in the upper 50s. While we expect these numbers to vary from field to field, once the rain stays away as harvest continues, we expect to continue seeing very good grain yield and quality. Lodging is being reported I some fields, but unless it becomes very windy and rainy over the next few weeks, this will likely not be a major problem. However, getting the wheat off as soon as possible will minimize the chance of lodging and other late season problems. If you opt to harvest early (moisture in the upper teens or lower 20s), make sure you dry the grain down to minimize post-harvest problems.
