Grain/Forage Update

We were out yesterday doing some soil samples before the cold and were in and out of some forage fields. It is still really wet, we even bogged the gator down in one field. Almost all of our grain and forage fields were planted late this year. Here is some rye planted for grazing. It is coming up and looking good, however low temperatures will unfortunately slow it down and take it more time before the cows can graze.

We also have wheat planted into December. If we’re planting late, we want to use an early maturing variety that has shorter vernalization requirements. When planting early maturing varieties, we have to also watch planting too early are since they can enter jointing phase before cold and have winter damage.  Therefore, with our grain crops, we’re mostly pushing back our weed control timing. This is usually a month after planting.

Here is some wheat I looked at before Christmas that is starting to tiller now. It has 2-3 tillers. This is important in terms of weed control. This field is okay for MCPA but not yet for a 2,4-D application. The weeds in the field right now are henbit, annual bluegrass and very little chickweed. We’re not used to seeing as much annual bluegrass, so what about its impact on wheat? UGA Extension Weed Scientist Dr. Stanley Culpepper says if annual bluegrass is thick and emerges with the grain then it can be concern. In this case, it did not emerge with wheat and is not the same size.

There are no raddish weeds yet, so this field could stand to go another week/week and a half before we do post-emergent treatment.

I did see an aphid here and there. Populations are very low and not close to treatment threshold. We need to see 6 aphids per row foot when plants are 6-10 inches before we consider treatment.
