Wheat Update

Wheat in Hill and McLennan Counties ranges from the start of grain fill to soft dough. We've been drenched again with more rains last Tuesday, and I'm concerned that these rains will cause nitrogen loss issues like they did last year for the corn. There is already yellowing in the low spots of some fields.

Some wheat fields may be experiencing damage from fall armyworm, but populations will vary greatly by location. We also still have a huge abundance of natural enemies that could be helping keep them in check, as well as the scattered aphid populations. Ladybugs, lacewings, and spiders can be found readily in most fields and will hopefully persist to aid us in other crops.

Leaf rust continues to spread in most fields, but wheat is past the flowering stage and is less vulnerable to yield losses. In fields that were not treated at Feekes 10, pockets of rust can be seen covering the flag leaves.

All species of stinkbugs can be found feeding occasionally on wheat heads. Seeing a few is not a cause for alarm, and generally they do not reach threshold levels.
