Winter wheat update – May 14, 2013

Wheat is finally exhibiting some vigor following a cool, wet April. The crop is lagging a few days behind normal, but is reaching growth stage 7 (two visible nodes) in the southern third of Michigan.

The Michigan Wheat Watchers submitted a May 13 report (table below). Armyworm moth catches have been sporadic and inconsistent. Brandon Hotchkin in Jackson County has the hot trap with over 50 moths caught to date. However, all other traps are logging just a few moths, if any. Presumably, the peak flight is still ahead.

Very few diseases have been reported. However, some septoria leaf spot has been reported and is expected to develop in the days to come. Aphids have been reported in the southern end of the state (Jackson and Lenawee counties), so this insect bears watching as it serves as the vector for barley yellow dwarf virus.

Nitrogen availability continues to be a concern. Some fields across the state are showing varying degrees of nitrogen availability and uptake. According to Michigan State University Extension, supplemental nitrogen may be warranted in some cases.

Some yellowing due to loss of N, some excess rain, and some possibly due to herbicides. Overall remains a good crop.

Some 1,000 ac have been worked-up in area, many others are using oats to fill in damaged spots in fields. Planted a bit of hard red spring wheat.

Late N applications show burn on top leaves. Relatively dry weather has slowed down disease development. Many farmers express intention to monitor crop for more aggressive fungicide use.

Ponded water has done damage and washed some N. No significant pest issues, except weeds. Plenty of moisture, but ground is finally firming up.
